## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The heartbeat system records agent runs and can add a run summary to
an issue.
> - The ACPX engine receives output text and internal thought text as
separate streams.
> - The default summary strategy joined both streams and could publish
internal text in an issue comment.
> - Paperclip already has final-output segmentation for run summaries.
> - This pull request makes final-output-only summaries mandatory and
removes the configuration bypass.
> - The benefit is that automatic issue comments contain the intended
final message instead of internal execution text.

**What happened?**
The ACPX engine used the full summary strategy when an adapter did not
set `summaryStrategy`. That strategy joined all text deltas, including
thought-stream text and intermediate narration. The heartbeat finalizer
could then store that summary as an issue comment.
**Expected behavior**
An automatic issue comment must use only the final output segment.
Configuration must not allow thought-stream text or intermediate
narration into that summary.
**Steps to reproduce**
1. Run an ACPX adapter without a configured `summaryStrategy`.
2. Emit an output delta, a thought delta, a tool call, and a final
output delta.
3. Read the generated run summary.
4. Observe that the old default included all text deltas.
**Paperclip version or commit**
`54b8bec44417511c623999613f9f1006f8af0517`
**Deployment mode**
Built from source with a local ACPX adapter.
## What Changed
- Limit ACPX run summaries to the final non-empty output segment.
- Ignore the legacy full-summary setting so configuration cannot bypass
containment.
- Update regression tests for the safe default and an attempted unsafe
override.
## Verification
- Observed the new guard fail before the implementation change because
the summary contained thought text.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "defaults run
summaries to the final output segment without thought text|does not
allow configuration to include thought text in run summaries"`. Result:
2 passed.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts`. Result: 130
passed.
- Ran `pnpm --filter @paperclipai/adapter-utils typecheck`. Result:
passed.
## Risks
- Run summaries are shorter for adapters that relied on full text
aggregation.
- The old `summaryStrategy: "full"` setting no longer changes summary
behavior. This is an intentional containment change.
- The change does not alter run logs or tool events. It changes only the
summary selected for downstream use.
> This is a focused security and privacy bug fix. It does not add
roadmap scope.
## Model Used
- OpenAI Codex on the GPT-5 family. The runtime did not expose the exact
model ID or context-window size. Reasoning, tool use, terminal
execution, and code editing were enabled.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local agent adapters (`claude_local`, `gemini_local`, `grok_local`,
…) are the integration surface that lets Paperclip run coding CLIs on
the host machine
> - The Kimi Code CLI (`kimi`, Moonshot AI) has a documented
non-interactive mode, `kimi -p --output-format stream-json` with session
resume via `kimi -r`, but Paperclip has no built-in adapter for it
> - So Kimi users (especially Kimi membership / OAuth subscribers)
cannot onboard their CLI to Paperclip agent teams
> - This pull request adds a complete built-in `kimi_local` adapter
(both execution engines, session management, instructions + skills
delivery, thinking-effort control, environment test, UI and CLI modules,
docs) following the established `gemini_local`/`grok_local` package
pattern
> - Kimi Code ships an ACP server (`kimi acp`), so the adapter runs on
Paperclip's shared acpx engine by default (streaming transcript with
live tool status, like `claude_local`/`gemini_local`) and falls back to
a headless CLI lane (`kimi -p --output-format stream-json`) when ACP
prerequisites are unavailable
> - The benefit is that Kimi Code becomes a first-class Paperclip agent
lane: selectable in the UI, resumable across heartbeats, with the same
operating context (instruction bundle, skills, effort) and streaming
transcript the other local adapters get
## Linked Issues or Issue Description

Duplicate/related prior PRs, per the dedup search (both appear stale: no
updates or maintainer review since May 2026, and both target an older
Kimi CLI interface; calling them out for reviewer context per
CONTRIBUTING.md):
- Refs #6276 (`feat: add kimi-local adapter`): targets an older
array-based content format (`{type: think}`/`{type: text}` blocks), not
the current documented stream-json schema
- Refs #5202 (`feat(adapter): add Kimi CLI local adapter with Wire
protocol support`): builds on a `--wire` JSON-RPC interface that current
Kimi Code CLI (0.27.0) no longer documents; the current documented
headless interface is `-p --output-format stream-json`
This PR is a fresh implementation against current master and the
currently documented/verified Kimi CLI behavior (see Verification).
Happy to fold in anything useful from the earlier attempts if a reviewer
prefers.
## What Changed
- **New adapter package** `packages/adapters/kimi-local`
(`@paperclipai/adapter-kimi-local`), modeled on
`gemini-local`/`grok-local`:
- `src/server/execute.ts`: spawns `kimi -p <prompt> --output-format
stream-json` (argv array, no shell), `-m <model>` only when configured,
`-r <sessionId>` when the stored session cwd matches the run cwd,
automatic fresh-session retry on unrecoverable-session errors,
headless-safe env (`CI=1`, `NO_COLOR=1`, `KIMI_CODE_NO_AUTO_UPDATE=1`,
`TERM=dumb`; user-configured values win), full remote (ssh/sandbox)
execution lane with runtime install via `@moonshot-ai/kimi-code`
- **Instruction bundle delivery**: the prompt path directive now names
the sibling instruction files (`./HEARTBEAT.md`, `./SOUL.md`,
`./TOOLS.md`) alongside the prepended entry file, and local runs pass
`--add-dir <instructions-dir>` so Kimi can actually open them (matching
`claude_local`). Without this, only the entry file reached Kimi and
agents improvised the operating workflow that `HEARTBEAT.md` documents
- **Thinking effort**: a configured `effort` is forwarded as the
`KIMI_MODEL_THINKING_EFFORT` operational override (Kimi has no
per-invocation effort flag). It is only sent for models that advertise
`support_efforts` (currently `kimi-code/k3`) to avoid provider
rejections, and `medium` maps to `high` since Kimi has no medium tier
(`low`/`high`/`max` pass through)
- **Skills delivery**: desired Paperclip skills are delivered via Kimi's
`--skills-dir` flag from a dedicated per-run directory (a local
snapshot, or the synced snapshot on remote targets), so skills load
reliably and in isolation. Paperclip never overwrites the shared
`$KIMI_CODE_HOME/skills` home, so skills installed by the operator or
other agents are left intact. `--skills-dir` is only passed when at
least one skill is desired, so unconfigured agents keep Kimi's default
skill discovery
- **Live run status**: the adapter now forwards each streamed
stream-json line to `onEvent` (assistant `content` as an assistant
snippet, `tool_calls` as tool-name events), which drives the
issue-thread activity indicator (`currentToolName` /
`lastAssistantSnippet` / `lastEventAt`). Previously the adapter only
wrote the raw run log, so the issue thread showed a stale "no output for
N s" line with no tool or reasoning context while Kimi worked. Tool
results are omitted so the last meaningful "Using X" / snippet is not
overwritten by a generic label
- `src/server/parse.ts`: parses the verified Kimi stream-json event
shapes (`assistant` text, `assistant.tool_calls` with JSON-string
arguments, `tool` results, trailing `meta.session.resume_hint` for
session-id capture) plus failure classifiers (`kimi_auth_required`,
transient network, unrecoverable session). A signaled exit (null exit
code, not a timeout) is now reported as a failure rather than coalesced
to success, and the error message names the terminating signal
- `src/server/skills.ts`: lists/syncs Paperclip skills for the adapter's
skill-management surface
- `src/server/test.ts`: environment test covering CLI resolution + `kimi
--version`, cwd check, auth detection (OAuth credential dirs, keyed
`[providers.*]` in config.toml, or the `KIMI_MODEL_NAME` +
`KIMI_MODEL_API_KEY` env pair), and a live hello probe
- `src/ui/` (stdout-line parser for transcripts, config builder) and
`src/cli/` (stream event formatter) modules
- Root metadata: three managed model aliases
(`kimi-code/kimi-for-coding`, `kimi-code/kimi-for-coding-highspeed`,
`kimi-code/k3`), effort-capable-model metadata (`EFFORT_CAPABLE_MODELS`,
effort mapping helpers), `agentConfigurationDoc`
- Tests: 101 tests across parse, execute (args building, resume gating,
retry, auth error code, timeout, signaled-exit failure, effort
forwarding/gating/mapping, `--add-dir` instructions directive,
`--skills-dir` gating, `onEvent` runtime-event forwarding), ACP engine
(engine resolution, acpx config build, node-version gate), ACP
transcript delegation, environment test, UI parse/build-config
- **ACP engine lane (default)** (`src/server/acp.ts` + shared
`adapter-utils/acpx-engine`): Kimi Code ships an ACP server (`kimi
acp`), so `kimi_local` now runs on Paperclip's shared acpx engine by
default, matching `claude_local`/`codex_local`/`gemini_local`. The
issue-thread transcript streams live (assistant text deltas, tool calls
with a `pending`->`completed` status lifecycle) instead of the CLI
lane's bursty complete-message output. Registered `kimi_local -> "kimi"`
in `ACPX_ADAPTER_AGENT_IDS` and resolved the built-in agent command to
`kimi acp`; `execute.ts` dispatches to the ACP executor first with an
automatic CLI fallback when ACP prerequisites fail (`engine=acp`
requires ACP, `engine=cli` pins the headless lane); `index.ts` falls
back to the shared acpx session codec; the UI/CLI delegate `acpx.*`
events to the shared acpx transcript parser and event formatter. The
headless CLI lane (above) remains as the fallback
- **Registration** (one entry each, mirroring existing adapters): server
adapter registry + `BUILTIN_ADAPTER_TYPES`, `AGENT_ADAPTER_TYPES`
(shared), UI adapter registry + display registry (`Kimi Code`, Moon
icon) + capabilities defaults, CLI adapter registry, `Dockerfile`
(package copy + `npm install --global @moonshot-ai/kimi-code@latest`),
`vitest.config.ts` workspace, `scripts/release-package-manifest.json`
- **Behavioral sets** mirroring `gemini_local` (Kimi resumes sessions
the same way): `GIT_SENSITIVE_LOCAL_ADAPTER_TYPES`,
`SESSIONED_LOCAL_ADAPTERS` (heartbeat + recovery),
`REMOTE_MANAGED_ADAPTERS`, ssh/sandbox execution-target allow-lists,
`ADAPTER_DEFAULT_RULES_BY_TYPE` (`timeoutSec: 0`, `graceSec: 15`), and
`LEGACY_SESSIONED_ADAPTER_TYPES` + `ADAPTER_SESSION_MANAGEMENT` in
adapter-utils
- **UI touch-points**: New Agent default-model branch, AgentConfigForm
command map (`kimi_local: "kimi"`) + model defaults + a Kimi-specific
thinking-effort option list (`Low`/`High`/`Max`, reflecting Kimi's tiers
rather than borrowing Claude's), OnboardingWizard (command map, model
default, `kimi login` / `KIMI_MODEL_NAME + KIMI_MODEL_API_KEY` auth
hints, manual-debug command line), InviteLanding enabled adapters
- **Control-plane skill install** (`cli/src/commands/client/agent.ts`):
`paperclipai agent local-cli` seeded the Paperclip control-plane skills
into `~/.codex/skills` and `~/.claude/skills` so Codex/Claude agents
auto-discover the API reference every run. Kimi had no equivalent
target, so `kimi_local` agents began each session without the
control-plane skill and rediscovered routes (e.g. the company-scoped
`POST /api/companies/{companyId}/issues`) by trial and error. Added
`~/.kimi-code/skills` (honoring `KIMI_CODE_HOME`) as a third install
target for parity. Independent of the per-run `--skills-dir` delivery,
which only applies to explicitly configured skills.
- **Docs**: `docs/adapters/kimi-local.md` (prerequisites, auth options,
config fields including `effort`, session resume, instruction bundle,
skills delivery, control-plane skill install) + a row in
`docs/adapters/overview.md`
Out of scope (deliberately): model profiles, built-in agent
`allowedAdapterTypes` additions.
## Verification\n\nCurrent-master rebase verification (OpenAI Codex,
2026-08-03): 13 focused files / 231 tests pass; adapter-utils, server,
UI, CLI, and Kimi adapter typechecks pass; full repository build and UI
token gates pass. The branch is conflict-free against master at head
`1249df117c5e12e5771b9a570a6340866450619e`.\n\nAutomated (all from repo
root, pnpm 9.15.4, Node 22):
- `vitest run packages/adapters/kimi-local`: 89/89 pass (includes
coverage for the instruction `--add-dir` directive, effort
forwarding/gating/mapping, `--skills-dir` gating, the signaled-exit
failure path, and `onEvent` runtime-event forwarding with cross-chunk
line buffering)
- `vitest run server/src/__tests__/adapter-registry.test.ts
server/src/__tests__/adapter-routes.test.ts
server/src/services/heartbeat-stop-metadata.test.ts
ui/src/adapters/adapter-display-registry.test.ts`: 37/37 pass
- `vitest run cli/src/__tests__/skills.test.ts`: 13/13 pass (the
control-plane skill install target follows the existing Codex/Claude
install path, whose symlink logic is unchanged)
- `vitest run packages/shared`: 307/307 pass; `vitest run
packages/adapter-utils`: pass except one pre-existing, unrelated failure
(`mcp-isolation.integration.test.ts` requires Claude CLI ≥ 2.1.207; host
has 2.1.185, fails identically on unmodified master)
- `pnpm --filter @paperclipai/adapter-kimi-local typecheck|build`, plus
typecheck of `server`, `ui`, `cli`, `adapter-utils`: all clean
- `pnpm install --frozen-lockfile`: passes (the PR diff itself contains
no lockfile changes, per repo policy; verified against a locally
regenerated lockfile)
- `node scripts/check-no-git-push.mjs` and `node
scripts/check-forbidden-tokens.mjs`: pass
- CI note: the `policy` job's release-bootstrap step is expected to stay
red until a maintainer bootstraps the first npm publish of
`@paperclipai/adapter-kimi-local`; see the CI Note for Maintainers
comment. All other contributor-actionable checks are green.
Manual end-to-end (real Kimi CLI 0.27.0, OAuth login, dev server on an
isolated instance):
1. Server `GET /api/adapters` lists `kimi_local` as builtin with correct
capability flags; models endpoint returns the three Kimi models
2. `POST .../adapters/kimi_local/test-environment`: all checks pass,
including a live `kimi -p` hello probe
3. Created a `kimi_local` agent and invoked two heartbeats: run 1
spawned `kimi -p ... --output-format stream-json`, Kimi used its `Read`
tool, produced the expected answer, and the session id was captured from
the `session.resume_hint` meta event; run 2 resumed the **same** Kimi
session (`sessionIdBefore == sessionIdAfter`) via `-r`
4. UI: adapter appears in the New Agent dropdown; selecting it shows the
Kimi command placeholder, the three models, and the Kimi config fields;
the run transcript renders Kimi tool calls via the adapter's stdout
parser
The instruction-bundle, thinking-effort, and `--skills-dir` changes
landed after the manual run above. They are covered by the unit tests
listed under Automated, and the Kimi CLI flags they rely on
(`--add-dir`, `--skills-dir`, `KIMI_MODEL_THINKING_EFFORT`) were
confirmed against the installed Kimi Code CLI 0.27.0 (`kimi --help`,
config-file thinking-effort docs).
Screenshots (assets branch on the fork, not part of the diff):
## Risks
- Low risk to existing behavior: the change is additive, one new
workspace package plus single-entry registrations alongside existing
adapters; no existing adapter code paths are modified.
- The adapter invokes the locally installed `kimi` CLI; like other local
adapters, run behavior depends on the host's Kimi version. The parser is
written against the documented/verified 0.27.0 stream-json schema and
degrades gracefully (malformed lines are skipped, failures surface as
run errors).
- `--skills-dir` overrides Kimi's auto-discovery of user and project
skills for the run. This is intentional (paperclip-managed agents get a
reproducible, isolated skill set), and it is only passed when at least
one Paperclip skill is desired, so unconfigured agents keep default
discovery.
- Thinking effort is only forwarded to models that advertise
`support_efforts` (currently `kimi-code/k3`); `EFFORT_CAPABLE_MODELS`
must be extended when more Kimi models gain support, otherwise a
configured effort is silently ignored for them.
- `Dockerfile` now installs `@moonshot-ai/kimi-code@latest` globally
alongside the other agent CLIs, so image size increases slightly.
- Maintainer action needed for the npm bootstrap gate: the `policy`
job's release-bootstrap step fails until the first npm publish of
`@paperclipai/adapter-kimi-local` (the gate from #5146 that every new
adapter package has passed through). Enrollment with `publishFromCi:
true` is required by the manifest validator (dropping the entry,
`false`, or `private` are all rejected), so this is intentionally left
to a maintainer. Remaining CI lanes are expected to run once it is done.
## Model Used\n\n- **Current-master rebase, conflict adaptation, and
registry-parity coverage:** OpenAI, **GPT-5 Codex** (Codex agent; exact
serving model ID and context-window size were not exposed to the
runtime), with repository, shell, Git, and GitHub tooling. It preserved
Hawik’s commit authorship, reconciled ACPX and environment-capability
changes, added current registry tests, and ran the verification
above.\n- **Adapter implementation and initial review:** Moonshot AI,
**Kimi K3 Coding** (latest), via **Kimi Code CLI v0.27.0**
(`kimi-code/k3` alias, 1M-token context window, thinking mode, agentic
tool use). The CLI agent explored the repo, wrote the adapter
implementation (delegated to a coder sub-agent of the same model), ran
tests, and drafted the first version of this PR body. A second
model-driven review pass (read-only, same model) audited the diff for
security/correctness before submission; its findings (shell-quoting
hardening, auth-detection false positive, session-compaction
registration, test gaps) were fixed and are included.
- **Harness-context fixes and review responses:** Anthropic, **Claude
Opus 4.8** (`claude-opus-4-8`) via Claude Code. Diagnosed from run logs
that Kimi received only the entry instructions file (not the
`HEARTBEAT.md`/`SOUL.md`/`TOOLS.md` bundle) and that `effort` was never
wired, then implemented the instruction `--add-dir` delivery,
`KIMI_MODEL_THINKING_EFFORT` forwarding, and `--skills-dir` skill
delivery, added the accompanying tests and docs, and addressed the
automated review comments (preserving external skills on remote sync,
treating a signaled exit as a failure). Also extended the `paperclipai
agent local-cli` installer to seed the control-plane skills into
`~/.kimi-code/skills` for Codex/Claude parity, wired `onEvent` runtime
events so the issue-thread activity indicator reflects Kimi's tool and
reasoning output live, and built the ACP engine lane (`kimi acp` via the
shared acpx engine, default) so the transcript streams with live tool
status like the other ACP adapters. The Kimi CLI flags, subcommand, and
env var relied on here were verified against the installed Kimi Code CLI
0.27.0.
- All CLI behaviors claimed here (`-p`, `--output-format stream-json`,
`-r` resume, event shapes, `--add-dir`, `--skills-dir`,
`KIMI_MODEL_THINKING_EFFORT`) were verified empirically against the
installed Kimi CLI, not assumed.

## Maintainer Addendum (2026-08-20)
The shared acpx-engine and issue-chat changes (run-summary segmentation,
placeholder tool-event coalescing,
`ISSUE_CHAT_TRANSCRIPT_MAX_VISIBLE_ENTRIES` 30 → 400, live-reasoning UI)
have been **extracted to #11761** so the cross-adapter behavior changes
review and revert independently — both commits there preserve @hawikk's
authorship. This PR is now the kimi-specific adapter only (60 files,
+3,793/−8, essentially pure addition); the only shared-engine touch left
is the `kimi acp` command resolution. `publishFromCi` is `true` — the
package name is bootstrapped on npm.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local agent adapters stream their work through the shared acpx
engine, which every ACP adapter (`claude_local`, `codex_local`,
`gemini_local`, custom ACP) runs on
> - Verbose streaming backends break two shared-engine behaviors: the
auto-posted run summary concatenates every text delta including the
thought stream (a long multi-tool run once auto-posted a ~50k character
monologue as an issue comment), and token-by-token tool-argument
streaming floods the run log with tens of thousands of
placeholder-titled in-progress events per run
> - These fixes were developed inside the `kimi_local` adapter PR, where
Kimi Code's streaming volume (~16,000 text deltas per run vs ~290 for a
comparable Claude run) surfaced both problems
> - Changing this behavior for all adapters at once is a fleet-wide
risk, and hardcoding adapter identities in shared code does not scale to
many adapters (or work at all for externally-shipped plugin adapters) —
so the behaviors become invocation-config parameters that an adapter's
own acpx config builder sets, with defaults preserving today's behavior
byte-for-byte
> - The benefit is that the machinery lands fully tested with zero
behavior change for existing adapters — pin tests prove it — the engine
carries no adapter identities, and any adapter (including `custom_acp`
configs for external backends) opts in declaratively
## Linked Issues or Issue Description
- Refs #9967 — extracted from the `kimi_local` adapter PR and
restructured to be inert by default; the commit preserves the original
author's (@hawikk) authorship.
**Current behavior**
When an acpx-engine run ends without the agent leaving a comment, the
auto-posted summary is every streamed text delta concatenated, thought
stream included. Backends that stream tool arguments emit tens of
thousands of placeholder-titled `in_progress` tool events into the
stored run log, pinning the live activity indicator to a generic "tool
call". There is no mechanism for an adapter to vary either behavior, and
shared code must never branch on adapter identities.
**Proposed behavior**
Two engine invocation-config parameters, read with behavior-preserving
defaults: `summaryStrategy` (`"full"` = existing concatenation, the
default; `"lastOutputSegment"` = segment output at tool starts, exclude
thought stream, post the last non-empty segment) and
`coalescePlaceholderToolUpdates` (`false` = never drop an event, the
default; `true` = coalesce placeholder-titled in-progress updates). An
adapter opts in from its own acpx config builder — the engine has no
per-adapter knowledge, no adapter identity appears anywhere in shared
code, and `custom_acp` agent configs can set the same knobs for external
verbose backends.
**Reason and benefit**
Existing adapters are provably unaffected — new pin tests assert the
default path's summary and tool-event output byte-for-byte, so any
future change that alters behavior for claude/codex/gemini/custom fails
the suite. The verbose-backend handling still lands fully tested,
activated declaratively by the adapter that needs it (the `kimi_local`
adapter PR sets both knobs in its config builder).
## What Changed
- `packages/adapter-utils/src/acpx-engine/execute.ts`: the run
preparation parses `summaryStrategy` and
`coalescePlaceholderToolUpdates` from the invocation config (validated,
defaulted); summary accumulation and `emitRuntimeEvent` branch on the
prepared values. The default path is the pre-existing code
(`textParts.join("")`, no event filtering). `buildAcpxRunSummary` is the
exported last-segment strategy.
- `packages/adapter-utils/src/acpx-engine/execute.test.ts`: a pin test
asserting the default path's exact summary (thought stream included) and
full tool-event stream (placeholder-titled in-progress updates present,
names restored); opt-in tests for each knob; a `buildAcpxRunSummary`
unit test.
- `ui/src/adapters/types.ts`: `UIAdapterModule` gains an optional
`transcriptPresentation` capability — `maxVisibleEntries` (issue-chat
transcript window, default 30) and `liveReasoningView` (`"ticker"`
default; `"scrollLog"` renders live reasoning in a scrollable
auto-following box with one entry per tool call).
- `ui/src/lib/issue-chat-messages.ts` and
`ui/src/components/IssueChatThread.tsx`: shared code resolves the hints
via `findUIAdapter(adapterType)` with today's defaults as fallback — no
adapter identities anywhere. The `scrollLog` rendering component ships
here but is unreachable until an adapter declares it.
- `ui/src/lib/issue-chat-messages.test.ts`: a capability test registers
a synthetic verbose adapter and asserts the wider window; the
pre-existing test keeps pinning the default 30-entry window.
No adapter declares any of this in this PR — every adapter renders and
summarizes exactly as before, and there is no per-adapter data anywhere.
The `kimi_local` adapter PR (#9967, stacked on this branch) is the first
consumer: it declares `transcriptPresentation` in its own UI module and
sets the engine knobs in its own acpx config builder.
## Verification
- Engine suite: 130/130 pass (126 existing + 4 new); chat suites
(`issue-chat-messages`, `IssueChatThread`, `RunChatSurface`): all pass
including the new synthetic-adapter capability test — 237 tests across
the touched surfaces
- The pin tests are the regression guard: the engine test encodes
today's summary text and tool-event sequence for a default-config run,
and the existing 30-entry-window test pins the default transcript
window, so "nothing changed for Claude/Codex users" is an executable
assertion, not a review judgment
- `pnpm --filter @paperclipai/adapter-utils --filter @paperclipai/ui
typecheck`: clean
## Risks
- Low: with no adapter setting the knobs, every code path taken in
production is the existing one. The only behavioral surface is additive
(an unused strategy and an unused filter), exercised by tests.
- The knobs are ordinary invocation-config keys, so a `custom_acp` agent
config can also set them — intended: an external verbose backend gets
the same handling without code changes. Both knobs only affect that
agent's own run summaries and run-log verbosity.

## Thinking Path
> - Paperclip is an open source app that manages AI agents for work
> - Paperclip runs agents in local and remote sandbox environments
> - A sandbox needs a bounded channel for commands and asynchronous
input
> - Daytona needs a real pseudo-terminal transport for this channel
> - The sandbox gateway also needs a mode that handles channel loss
safely
> - This pull request adds the Daytona transport and gateway mode behind
a default-off kill switch
> - The benefit is a tested foundation for later transport selection
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above): sandbox providers, plugin SDK,
server settings, and shared types.
**Problem or motivation**
The merged sandbox protocol has no runtime transport for Daytona. The
generated sandbox gateway also has no duplex mode. A later
transport-selection change needs both parts and a safe per-run gate.
**Proposed solution**
Add a Daytona `duplexCommandStream` transport over a raw
pseudo-terminal. Add a generated gateway mode named `duplex_v1`. Add the
`enableSandboxDuplexBridge` setting with a default value of `false`.
Keep transport selection disabled until a later pull request.
**Alternatives considered**
Keep the protocol unused until the transport-selection change. This
would delay provider tests and leave the gateway path without direct
coverage.
**Roadmap alignment**
This change supports the completed Roadmap item for cloud and sandbox
agents. It extends the merged sandbox channel foundation in pull request
#11738.
**Additional context**
The Daytona provider remains an untrusted boundary. Deployments must use
least-privilege provider credentials and provider-side quota controls.
Operators must name an owner for duplex telemetry retention before
rollout.
## What Changed
- Add the Daytona `duplexCommandStream` capability over a raw
pseudo-terminal.
- Add a launch wrapper that disables echo and newline translation for
NDJSON frames.
- Close channels on lease release, destroy, resume of a stopped worker,
and worker shutdown.
- Declare the capability in the Daytona manifest and set
`PLUGIN_VERSION` to `0.1.5`.
- Add the worker-to-host notification sink at `ctx.duplexChannel.data`
and `ctx.duplexChannel.exit`.
- Add the generated sandbox gateway mode
`PAPERCLIP_API_BRIDGE_MODE=duplex_v1`.
- Add channel-loss results of `409 outcome_indeterminate` and `503
bridge_unavailable`.
- Add the per-run setting `enableSandboxDuplexBridge`, with a default
value of `false`.
- Add unit tests, generated-source codec tests, lifecycle tests, and a
credential-gated live Daytona test.
## Verification
- Daytona suite: 185 tests pass.
- Adapter utilities: 754 tests pass and 4 tests skip.
- Plugin SDK: 62 tests pass.
- Shared package: 28 tests pass.
- Server duplex tests pass.
- Shared, plugin SDK, server, and Daytona TypeScript checks pass.
- The live Daytona test passes 3 cases when `DAYTONA_API_KEY` is set.
- The live Daytona test skips 3 cases without `DAYTONA_API_KEY`.
- CI must run the full workspace typecheck, test, and build gates after
PR creation.
## Risks
- The Daytona control plane and pseudo-terminal remain untrusted
boundaries.
- The duplex gateway changes behavior only when the mode and per-run
setting enable it.
- A lost channel fails requests without replay, so callers must handle
indeterminate outcomes.
- The transport-selection change must require both `duplexCommandStream
=== true` and `enableSandboxDuplexBridge === true`.
- The provider credential and quota limits need operator control before
rollout.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox-managed runtimes move files between a host and an isolated
sandbox
> - The git-bundle export path reads the full bundle into host memory
> - The workspace restore path already uses the provider native
`syncOut` transfer
> - This pull request uses `syncOut` for bundle export and keeps
`readFile` as a fallback
> - The change reduces host buffering and exposes the transfer to
provider tracing
## Linked Issues or Issue Description
**What happened?**
The sandbox git-bundle export used `client.readFile` even when the
provider supported native `syncOut`. The path buffered the full bundle
in host memory and used a chunked base64 command loop.
**Expected behavior**
The export should use one confined native file transfer when the
provider supports `syncOut`. Providers without that capability should
keep the existing `readFile` fallback.
**Steps to reproduce**
1. Prepare a sandbox-managed runtime with native `syncOut` support.
2. Export the sandbox git bundle.
3. Inspect the sync operations and file reads.
4. Confirm that the bundle uses one native file mapping and that the
status file still uses `readFile`.
**Paperclip version or commit**
Commit `3fc88d14be7133867897e87838276e15aba675fd`.
**Deployment mode**
Built from source. The change applies to sandbox-managed runtime
execution.
**Additional context**
This PR contains a focused bug fix. No public issue matched this change
during the duplicate search.
## What Changed
- Route bundle export through `nativeSyncOut` when the provider supports
it.
- Keep the existing `readFile` fallback for providers without native
sync support.
- Confine the native bundle mapping with `assertSyncOperationsConfined`.
- Cover the native path, fallback path, retry path, and confinement
checks with unit tests.
## Verification
- `npx vitest run
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` — 52 tests
passed.
- `npx tsc --noEmit` in `packages/adapter-utils` — passed.
- The PR CI workflow must pass before merge.
## Risks
Low risk. The native path runs only when the provider advertises
`syncOut`. The existing `readFile` path remains available as a fallback.
Native transfer progress reports only start and finish events.
## Model Used
OpenAI GPT-5 Codex. Exact runtime model ID: GPT-5 Codex. Context window:
not exposed in this run. Capabilities used: code review, shell tools,
GitHub CLI, and Paperclip API coordination.

## Thinking Path
> - Paperclip provides a control plane for companies that run AI agents.
> - Sandboxed agents need a safe execution path for persistent command
streams.
> - The existing callback transport does not provide a bounded, generic
duplex route.
> - The host must control capability access, route identity, protocol
limits, and close behavior.
> - This pull request adds an opt-in duplex command-stream foundation
across the sandbox layers.
> - The feature stays inert because no current provider declares the
capability.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above)
**Problem or motivation**
Sandbox command execution needs a persistent host-to-sandbox stream. The
current callback bridge uses a file transport and does not provide this
generic route.
**Proposed solution**
Add a fail-closed provider capability, generic worker protocol messages,
a host-owned bounded route, cross-layer service mediation, and a
versioned newline-delimited frame codec.
**Alternatives considered**
Keep the file transport and add feature-specific commands. This does not
provide one reusable duplex contract or host-owned route bounds.
**Roadmap alignment**
This work supports the completed Cloud / Sandbox agents roadmap area and
the safe autonomy goal in the product definition.
**Additional context**
The change passed a two-stage security review. The final code review
verdict was approve after fixes for active-stream bounds and
service-layer capability mediation.
## What Changed
- Add the opt-in `duplexCommandStream` provider capability with
fail-closed narrowing.
- Add duplex open, write, stop, and close requests and data and exit
notifications to the plugin worker protocol.
- Add a host-owned route with bounds for chunk size, cumulative bytes,
lifetime, protocol errors, pending requests, and pre-bind buffering.
- Add close acknowledgement handling with worker retirement when the
close remains unconfirmed.
- Wire `openDuplexChannel` through the execution target, runtime
service, and plugin worker.
- Add a versioned frame codec with shared wire-compatibility vectors and
split UTF-8 handling.
## Verification
- `server/src/__tests__/plugin-worker-manager-duplex.test.ts` passes 18
tests.
- `server/src/__tests__/environment-execution-target-duplex.test.ts`
passes 11 tests.
- `packages/adapter-utils/src/duplex-frame-codec.test.ts` passes 38
tests.
- `server/src/__tests__/sandbox-capability-contract.test.ts` passes 15
tests.
- Setup-token pseudo-terminal regression tests pass 47 tests.
- Server TypeScript check passes.
- Continuous integration will run the full required test, typecheck,
build, and policy checks.
## Risks
- Providers that opt into the capability must implement the complete
worker protocol.
- Route limit defaults can close a stream when a workload exceeds the
configured bounds.
- The capability remains disabled for current providers, so current
production behavior does not change.
## Model Used
OpenAI GPT-5 (`gpt-5`), with tool use and code execution. The model
reviewed and prepared this pull request from the supplied implementation
and verification record.

## Thinking Path
> - Paperclip runs AI agents through local and remote execution
adapters.
> - Sandbox providers move workspace and asset files before and after
agent runs.
> - Serial file transfers delay startup and teardown when several
operations do not depend on each other.
> - Providers need an opt-in contract so existing providers keep their
serial behavior.
> - This pull request adds a bounded scheduler and routes inbound and
outbound sync operations through it.
> - The benefit is shorter sandbox setup and teardown with stable
errors, clear telemetry, and a safe opt-in path.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above): packages/shared,
packages/adapter-utils, packages/plugins, and server.
**Problem or motivation**
Sandbox sync processes the workspace, assets, and referenced projects in
series. This adds avoidable wait time to agent startup and teardown.
**Proposed solution**
Add a fail-closed provider capability named concurrentSyncOperations.
Use a bounded scheduler with a limit of four operations. Preserve
operation order for error reporting. Keep non-opted-in providers on the
serial path.
**Alternatives considered**
Increase the serial transfer speed or add provider-specific schedulers.
Those options do not provide one shared contract or stable behavior
across providers.
**Roadmap alignment**
ROADMAP.md lists cloud and sandbox agents as a product area. This change
improves sandbox execution without changing the control-plane contract.
**Additional context**
The Daytona provider opts in. Board trials on this commit showed overlap
for inbound sync and outbound restore, with no referenced-project
staging failures.
## What Changed
- Add the concurrentSyncOperations sandbox capability and fail-closed
parsing.
- Add a bounded settle-all scheduler with stable input-order errors.
- Parallelize inbound workspace, asset, and referenced-project sync
operations when the provider opts in.
- Parallelize outbound workspace and asset restore operations when the
provider opts in.
- Surface referenced-project failure text in run logs and server
telemetry.
- Add Daytona sync spans and the capability declaration.
- Preserve in-flight upload scratch tarballs during workspace wipe.
- Add unit and regression tests for the scheduler, coordinators,
provider behavior, telemetry, and wipe race.
## Verification
- Run the adapter-utils and server type checks.
- Run the targeted adapter-utils, server, and Daytona test suites.
- Run the full automated sweep.
- Review six cold Daytona trials, with three serial and three parallel
runs.
- Confirm that parallel trials show inbound overlap and outbound restore
overlap.
- Confirm that providers without the capability keep serial behavior.
## Risks
- Providers must opt in only when their file operations can run safely
at the same time.
- A provider that declares the capability incorrectly can expose
transfer races.
- The scheduler keeps a limit of four to bound resource use.
- Providers without the capability keep the prior serial behavior.
## Model Used
OpenAI GPT-5 in the Codex runtime. The model used tool calls, code
inspection, and GitHub workflow support. The model did not author the
implementation commits.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox agents need a safe login path for each supported adapter
> - Codex device login and Claude setup-token login used separate
session stores and route logic
> - Separate stores made session lookup, expiry, and login capability
checks harder to keep consistent
> - This pull request unifies both flows on one session table and one
capability contract
> - The benefit is one company-scoped login model with public session
identifiers and shared lifecycle rules
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above)
**Problem or motivation**
Codex and Claude sandbox login used separate session stores and
different route paths. This split increased the risk of inconsistent
company scoping, session lookup, and cleanup.
**Proposed solution**
Use `adapter_auth_sessions` for both login flows. Use public session
identifiers for API access. Select login behavior from projected adapter
capability data. Share the route spine, lease arguments, runner
lifecycle, and reaper rules.
**Alternatives considered**
Keep two session tables and add matching fixes to both routes. This
keeps duplicate logic and does not provide one capability contract, so
this pull request uses shared infrastructure.
**Roadmap alignment**
This change supports the shipped Cloud / Sandbox agents milestone in
`ROADMAP.md`.
## What Changed
- Unify Codex device login and Claude setup-token login on
`adapter_auth_sessions`.
- Return and look up sessions with company-scoped public session
identifiers.
- Enforce one active session for each company, owner, and adapter.
- Share the login route spine, sandbox lease arguments, runner
lifecycle, and missing-auth check.
- Add a standalone setup-token reaper with adapter-specific row
selection.
- Add optional login capability projection for adapters and drive route
and UI selection from that data.
- Rename the provider flag to `supportsLoginPty` and validate its
deprecated alias.
- Remove the old Claude setup-token session table and add the required
migrations.
## Verification
- Server typecheck passed with `tsc`.
- Database typecheck passed.
- UI typecheck passed with `tsc -b`.
- Codex login service and route suites passed.
- Setup-token session, route, and reaper suites passed.
- Adapter session schema, plugin validator, capability projection, UI
render, and Daytona suites passed.
- GitHub Actions must confirm the complete CI gate after pull request
creation.
## Risks
- The migrations remove short-lived in-flight login rows during
deployment. A login that spans the migration can continue until its
provider lease expires.
- The Codex credential store remains company-scoped. A cross-owner
credential race remains a documented, board-accepted risk.
- API clients that use internal session row identifiers no longer work.
The API accepts only public session identifiers.
## Model Used
Codex, GPT-5, exact runtime model ID not exposed in this handoff, large
context window, reasoning, and repository tool use. The implementing
engineer produced the code with AI assistance.

> - This pull request grafts the imported tree onto the current head as
a single commit instead of failing
> - The benefit is that a history rewrite inside the sandbox can no
longer lose a run's work
## Linked Issues or Issue Description
No existing issue found. I searched issues and PRs for "unrelated
histories", "Failed to merge concurrent", and "shallow". Depends on
#11637 (merged; the graft commit reuses its identity constant). This PR
is now rebased onto `master`.
**What happened?**
An agent run amended a commit inside its sandbox workspace to address
review feedback. The sandbox clone is depth-1 shallow, so git treated
the boundary commit as parentless and the amend produced a root commit.
At finalize, the host-side sync failed with `Failed to merge concurrent
remote git histories for <sha>` and the run was marked failed. A
follow-up run had to repair the branch by hand: fetch the true parent
from origin and rebuild the commit with `git commit-tree`.
**Expected behavior**
The sync must never strand completed work. When the imported history
shares no ancestor with the local one, the imported tree should still
land on the current head, with the imported message preserved and the
graft recorded.
**Steps to reproduce**
1. Start a run whose workspace transport uses the shallow clone path
(`withShallowGitWorkspaceClone`, depth 1).
2. Inside the sandbox workspace, run `git commit --amend` on the
boundary commit. The result is a parentless root commit.
3. Finish the run. The host-side `integrateImportedGitHead` finds no
merge base, `merge-tree` fails, and the run fails.
## What Changed
- `git-workspace-sync.ts`: new exported
`createUnrelatedHistoryGraftCommit` helper. It reads the imported head's
tree and message, and creates one commit on top of the current head with
the deterministic sync identity and a trailer that records the graft and
both shas.
- `integrateImportedGitHead` (both the remote-git-sync version and the
SSH copy in `ssh.ts`): when `merge-base` reports no common ancestor,
graft instead of throwing. The ref update keeps the same
compare-and-swap and concurrent-retry semantics as the merge path.
- The graft is gated on `git merge-base` exiting with status 1 — the
no-ancestor signal. Operational failures (timeout, missing object,
repository error) keep the loud merge failure instead of rewriting the
tip.
- New regression tests: one builds the exact shallow-amend shape (a root
commit rebuilt from the base tree) and asserts the graft lands on the
current head with the imported tree, subject, and graft trailer; one
integrates a well-formed sha the repository does not hold and asserts
the integration still throws with the branch tip unchanged.
## Verification
- `pnpm vitest run
packages/adapter-utils/src/git-workspace-sync.test.ts` — 19/19 pass
(includes the new graft test and the merge-base failure-discrimination
test).
- `pnpm --filter @paperclipai/adapter-utils typecheck` — clean.
- Full `pnpm vitest run packages/adapter-utils`: every file passes
except `local-process-sandbox.test.ts`, which fails identically on an
untouched `master` checkout on macOS (bubblewrap-dependent,
pre-existing, unrelated).
## Risks
- Behavioral shift: unrelated imported histories previously failed the
integration; now they land as a squash-graft. In this degenerate case
there is no base to merge against, so the imported tree is taken
wholesale and concurrent local-only tree changes are superseded at the
tip. The local commits keep their place in the graft's ancestry, and the
trailer records both shas, so nothing is unrecoverable. The old behavior
lost the imported work instead, which is the worse failure for an
autonomous run.
- The graft reuses the imported head's commit message, so branch history
still reads naturally after a sandbox rewrite.
## Model Used
- Claude Fable 5 (`claude-fable-5`), extended thinking, via Claude Code
CLI (tool use for code exploration, test runs, and verification).

## Linked Issues or Issue Description
No existing issue found. I searched issues and PRs for "Author identity

**What happened?**

identity unknown ... fatal: unable to auto-detect email address (got
'node@<container-id>.(none)')`. The adapter recorded the whole run as
failed, and the host worktree kept the stale head. Any container
deployment without a global gitconfig reproduces this; I observed it on
a Paperclip Cloud stack.
**Expected behavior**
Commits that the sync machinery itself creates must not depend on
ambient host git configuration. The merge commit is machine-authored, so
it should carry a deterministic Paperclip identity.
**Steps to reproduce**
1. Run the Paperclip server in a container with no
`user.name`/`user.email` git config and a hostname git cannot turn into
an email.
2. Let a run's sandbox branch diverge from the host worktree, so both
sides advance.
3. Workspace finalize calls `integrateImportedGitHead`. The `git
commit-tree` step fails with "Author identity unknown" and the run
fails.
## What Changed
- `git-workspace-sync.ts`: new exported `GIT_SYNC_COMMIT_IDENTITY_ARGS`
(`-c user.name=Paperclip -c user.email=noreply@paperclip.ing`), applied
to the `commit-tree` call in `integrateImportedGitHead`.
- `ssh.ts`: the SSH-sync copy of `integrateImportedGitHead` applies the
same identity args to its `commit-tree` call.
- New regression test: builds divergent histories in a repo with no
configured identity and asserts the sync merge commit is created with
the deterministic identity, correct parents, and merged tree.
## Verification
- `pnpm vitest run
packages/adapter-utils/src/git-workspace-sync.test.ts` — 18/18 pass.
- `pnpm --filter @paperclipai/adapter-utils typecheck` — clean.
- Negative proof: with the source fix stashed, the new test fails on the
identity assertion.
- Full `pnpm vitest run packages/adapter-utils`: every file passes
except `local-process-sandbox.test.ts`, which fails identically on an
untouched `master` checkout on macOS (bubblewrap-dependent,
pre-existing, unrelated).
## Risks
Low risk. The change only adds `-c` identity flags to two
machine-generated commit invocations. `GIT_AUTHOR_*` / `GIT_COMMITTER_*`
environment variables still take precedence over `-c` when an operator
sets them, so existing deployments that configure an identity keep their
behavior.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters run agent sessions through the ACPX engine
> - The ACPX engine handled one run attempt as a long implicit procedure
> - That shape made resource ownership, cleanup order, and failure
behavior hard to verify

ledger, separate run sites, and explicit turn and settlement sequences
> - The benefit is clear ownership, one cleanup path, safer session
reuse, and testable failure behavior
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The ACPX engine manages startup, turn execution, session reuse, and
cleanup inside one large run procedure.
**Current behavior**
The run procedure owns several resources through implicit control flow.
Cleanup and session reuse behavior depend on lane-specific branches and
error paths.
**Proposed behavior**
The coordinator owns the run attempt. A typed ledger records six
resources and their states. Host and sandbox run sites own lane-specific
acquisition. Turn and settlement sequences expose typed outcomes. The
engine emits allowlisted phase telemetry.
**Reason and benefit**
Explicit ownership makes cleanup and failure behavior easier to inspect.
The fault matrix and characterization tests protect the external result
while the refactor reduces hidden control flow.
**Breaking changes**
None to the public adapter contract. The host warm-save path now closes
and relaunches the runtime because a transferred runtime could retain a
run-scoped credential. A cold session-handshake failure now closes the
created runtime.
**Additional context**
This pull request contains the ACPX engine lifecycle refactor, its
tests, and the lifecycle document.
## What Changed
- Add a run coordinator for startup, turn execution, settlement, and
result reproduction.
- Add a typed resource ledger with open, sealed, and consumed states.
- Add host and sandbox run sites for lane-specific resource acquisition.
- Replace separate runtime maps with a generic session reuse store.
- Split session fingerprint identity from the outer session key.
- Add typed turn and settlement sequences with one cleanup owner.
- Add a closed allowlist for phase telemetry.
- Add characterization tests and a 17-case fault matrix.
- Add `doc/acp-run-lifecycle.md`.
## Verification
- `npx vitest run packages/adapter-utils/src/acpx-engine/` passes 18
files and 286 tests at the submitted commit.
- `pnpm --filter @paperclipai/adapter-utils typecheck` reports 0 errors
at the submitted commit.
- Run the full pull request checks after GitHub starts CI.
- Run Greptile review after the pull request opens.
## Risks
- The refactor changes internal control flow across the ACPX engine.
- Host warm-save behavior now closes and relaunches the runtime.
- Settlement changes the handling of a cold session-handshake failure
from a leak to a close.
- The characterization baselines and fault matrix reduce the risk of an
external behavior change.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The server authenticates each agent request in `actorMiddleware`
before it attributes chat comments
> - When an agent bearer token failed verification, the middleware
called `next()` with no error and the request continued without an agent
actor
> - The request then fell back to the local user actor, so the server
stored agent replies as user comments
> - The task chat UI renders user comments in blue bubbles, so agent
messages appeared as blue user bubbles
> - This pull request rejects invalid agent credentials with 401 instead
of a silent downgrade
> - The benefit is that agent messages keep agent attribution, and
broken credentials fail loudly with a clear retry message
## Linked Issues or Issue Description
**What happened?**
A user cancelled an onboarding question card. The agent posted a
follow-up reply. The reply appeared in a blue bubble, which the UI
reserves for human messages. The agent run held an expired local agent
JWT. The auth middleware could not verify the token, called `next()`
without an actor, and the request fell back to the local user identity.
The server stored the agent comment as a user comment.
**Expected behavior**
Agent messages always render as agent bubbles. A request with invalid
agent credentials must fail with 401 so the adapter can refresh
credentials and retry. It must not post content under a human identity.
**Steps to reproduce**
1. Start a local Paperclip instance.
2. Give an agent run an expired or malformed agent JWT.
3. Let the agent post an issue comment through the API bridge.
4. Before this change: the comment is stored with the local user
identity and renders as a blue bubble. After this change: the request
fails with 401 and a message that tells the caller to obtain fresh
credentials.
## What Changed
- `server/src/middleware/auth.ts`: a bearer token that fails
verification now produces a 401 `unauthorized` error instead of a silent
fall-through to the anonymous/local-user actor.
- The 401 message states the cause: expired token, unverifiable token,
empty bearer token, missing agent record, agent record in another
company, terminated agent, or agent pending approval.
- The API-key path now also rejects an agent record whose company does
not match the key.
- `packages/adapter-utils/src/execution-target.ts`: the bridge proxy now
writes a `comment id: <id>` marker to the run log for each posted issue
comment, so misattributed comments can be traced to a run.
- `ui/src/components/task-chat/task-chat-adapter.test.ts`: a regression
test asserts that a recovered `local-board` comment with a derived agent
author renders as an agent bubble, not a user bubble.
- `server/src/__tests__/agent-auth-middleware.test.ts` and
`packages/adapter-utils/src/execution-target-sandbox.test.ts`: new tests
cover each rejection path and the log marker.
## Verification
- Run `pnpm vitest run src/__tests__/agent-auth-middleware.test.ts` in
`server/` — 14 tests pass.
- Run `pnpm vitest run execution-target-sandbox` at the repo root — 44
tests pass.
- Run `pnpm vitest run
src/components/task-chat/task-chat-adapter.test.ts` in `ui/` — 4 tests
pass.
- Manual check: post an issue comment with an expired agent JWT; the API
returns 401 with a retry message and no comment is stored.
## Risks
- Behavioral shift: requests that previously continued as anonymous or
local-user actors after a failed agent-token verification now receive
401. Any caller that relied on the silent downgrade must refresh its
credentials. This is the intended fix, and the adapters already handle
401 with a credential refresh.
- No schema or migration changes. Low risk otherwise.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Workspaces let users and agents inspect files that belong to an
issue
> - Changed-file views use full-tree Git status scans
> - Many issue views could start those scans at the same time and make
the server unresponsive
> - Route-level limits did not protect the process or coalesce work for
one repository
> - This pull request adds one bounded scheduler for every expensive
workspace Git scan
> - It also starts browser scans only when the file panel is open and
visible
> - The benefit is bounded child-process use and responsive health
checks during request storms
## Linked Issues or Issue Description
**What happened?**
Many changed-file requests could start full `git status --porcelain=v1
-z --untracked-files=all` scans at the same time. One production
incident produced about 270 direct Git child processes. The Node process
stayed alive but stopped answering health requests in time.
**Expected behavior**
Paperclip must bound expensive Git work across all companies, actors,
issues, repositories, and browser tabs. Duplicate requests for one
worktree must share work. Excess requests must fail fast with a
retryable response. Hidden or closed file panels must not start scans.
**Steps to reproduce**
1. Open changed-file views for many issue and actor keys.
2. Send requests for two large workspace roots at the same time.
3. Observe that route-level limiter keys allow many full Git scans to
run together.
4. Observe delayed health responses and accumulated Git children.
**Paperclip version or commit**
Reproduced on master before commit `43ab441f0f`.
**Deployment mode**
Self-hosted server with local workspace repositories.
## What Changed
- Add a process-wide scheduler with configurable concurrency, queue
capacity, timeout, and cache TTL.
- Add fair admission, a bounded queue, canonical worktree keys,
single-flight joins, and bounded result caching.
- Add subprocess timeouts, TERM-to-KILL escalation, bounded output,
waiter cancellation, and slot cleanup.
- Route full-tree status work from file resources, workspace runtime,
execution workspaces, and adapter overlay sync through the scheduler.
- Return stable retryable `503` and `504` error codes for saturation and
timeout.
- Add structured logs with safe workspace hashes, durations, queue
state, cache use, joins, and terminal outcomes.
- Gate UI queries on panel and document visibility. Cancel queries on
close, hide, unmount, and workspace change.
- Disable focus and reconnect bursts. Keep one explicit refresh action
and a retryable unavailable state.
- Document the 10-second default freshness tradeoff and all
configuration variables.
- Add unit, route, UI, adapter, and deterministic 500-request load
coverage.
## Verification
- `pnpm -r typecheck`
- `pnpm build`
- `pnpm check:token-gates`
- `pnpm --filter @paperclipai/server exec vitest run
src/services/workspace-git-operation-scheduler.test.ts
src/__tests__/file-resources-git-scan-load.test.ts --reporter=dot` — 16
tests passed.
- `pnpm --filter @paperclipai/ui exec vitest run
src/components/WorkspaceFileBrowser.test.tsx
src/lib/page-visibility.test.ts --reporter=dot` — 38 tests passed.
- `pnpm --filter @paperclipai/adapter-utils exec vitest run
src/git-workspace-sync.test.ts --reporter=dot` — 16 tests passed.
- Existing file-resource, workspace-runtime, and execution-workspace
regression selections passed.
- Two cleanup safety regressions prove failed scans preserve the
worktree before archive and at the final deletion fence.
- Before: the incident produced about 270 Git children and health
requests timed out.
- After: 500 concurrent requests across 500 issue keys, 73 actors, and
two roots started two underlying scans. Peak scan concurrency was 2. All
500 requests succeeded. Health p99 was 4.94 ms. The harness found zero
unreaped children.
- The full local Vitest run passed 4,267 tests. Ten existing fixed-port
HTTPS exposure tests could not run because this host already owns
Tailnet listeners on ports 42000 and 52000. Clean GitHub CI is the final
full-suite result.
- Latest-head GitHub CI passed all required test, typecheck, build,
canary, e2e, policy, and security gates.
- Greptile completed at 5/5 with zero unresolved comments,
recommendations, or follow-ups.
## Risks
- Changed-file results can be up to 10 seconds old by default. Explicit
refresh remains available.
- A full queue returns a retryable `503` instead of waiting without a
bound.
- A scan that exceeds the default 8-second deadline returns a retryable
`504` and terminates its process group.
- Operators can tune all limits with documented environment variables.
Safe defaults protect local and shared servers.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Managed agents run inside a sandbox and reach the Paperclip server
only through the sandbox callback bridge, which forwards a fixed route
allowlist (`DEFAULT_SANDBOX_CALLBACK_BRIDGE_ROUTE_ALLOWLIST`)
> - The `paperclip-create-agent` skill instructs an agent to call
adapter/icon discovery endpoints, compare existing agent configurations,
submit a hire request, and link the resulting approval to its source
issue
> - None of those routes were on the bridge allowlist, so a sandboxed
agent following the skill correctly hit `Route not allowed` on every
call — including the hire `POST` itself — making hiring impossible from
inside a sandbox
> - This pull request adds the six routes the skill uses to the bridge
allowlist, while keeping direct agent creation (`POST
/api/companies/:id/agents`) denied
> - The benefit is that hiring works end-to-end for sandboxed agents
through the approval-gated `agent-hires` path, without widening the
bridge beyond what the skill needs
## Linked Issues or Issue Description
No public issue exists; describing the bug in-PR (bug template fields):
- **What happened:** A managed agent running in a sandbox followed the
`paperclip-create-agent` skill and got `Route not allowed` from the
callback bridge on every endpoint the skill documents — adapter
discovery (`/llms/agent-configuration.txt`,
`/llms/agent-configuration/:adapterType.txt`, `/llms/agent-icons.txt`),
config comparison (`GET /api/companies/:id/agent-configurations`), the
hire submission (`POST /api/companies/:id/agent-hires`), and approval
linking (`POST /api/issues/:id/approvals`).
- **Expected behavior:** An agent with hiring permission can complete
the hire flow from inside a sandbox; the bridge forwards the skill's
routes and the server enforces authorization (`canCreateAgents`).
- **Impact:** Hiring by sandboxed agents was fully broken — the failure
is in the transport allowlist, not permissions, so no configuration
could work around it.
Related: #8981 (companion fix making the `paperclip-create-agent` skill
available to agents that can hire; supersedes #8823). The two changes
serve the same end-to-end hire flow but are independently mergeable —
this PR is purely the bridge transport allowlist.
Supersedes #8853.
## What Changed
- `packages/adapter-utils/src/sandbox-callback-bridge.ts`: add six
routes used by the `paperclip-create-agent` skill to
`DEFAULT_SANDBOX_CALLBACK_BRIDGE_ROUTE_ALLOWLIST` (three `GET /llms/...`
discovery routes, `GET .../agent-configurations`, `POST
.../agent-hires`, `POST /api/issues/:id/approvals`), with a comment
documenting why direct agent creation stays denied
- `packages/adapter-utils/src/sandbox-callback-bridge.test.ts`: assert
the six routes are allowed, and add negative cases proving the regexes
do not over-match (no `POST .../agents`, no non-`.txt` or arbitrary
`/llms` files, no `agent-hires` sub-resources)
## Verification
- `npx vitest run
packages/adapter-utils/src/sandbox-callback-bridge.test.ts` — 13/13
tests pass locally
- `npx tsc --noEmit -p packages/adapter-utils` — clean
- Manual: run a managed agent in a sandbox, invoke the
`paperclip-create-agent` skill, and confirm the discovery calls, hire
`POST`, and approval linking all pass through the bridge; `POST
/api/companies/:id/agents` still returns `Route not allowed`
## Risks
- Low risk: additive allowlist entries only; anchored regexes with
`[^/]+` segments prevent over-matching (covered by tests)
- The bridge allowlist bounds surface area but does not replace
server-side authorization — the hire `POST` remains approval-gated and
permission-checked (`canCreateAgents`) on the server

## Linked Issues or Issue Description
Related public work:
[#9488](https://github.com/paperclipai/paperclip/pull/9488) adds
first-class recognition for `CLAUDE_CODE_OAUTH_TOKEN` in headless and
remote runs. Related public issue:
[#2681](https://github.com/paperclipai/paperclip/issues/2681) requests
Claude Code subscription support. This pull request adds the login
transport and new-agent UI flow that those changes do not provide.
**Subsystem affected:** Claude local adapter, server login probes,
sandbox provider setup, cleanup recovery, and the new-agent UI.
**Problem or motivation:** The Test lanes did not show the sandbox login
panel in all supported cases. Test results also exposed raw probe
diagnostics, and JSON escapes could end secret redaction early.
**Proposed solution:** Surface the login capability through the bundled
provider manifest. Prepare the same probe runtime in the ACP lane. Send
diagnostics only to redacted server logs. Keep Test checks on fixed
public messages. Normalize login URL hints to allowlisted HTTPS Claude
and Anthropic hosts. Consume JSON escapes during redaction. Preserve
failed sandbox cleanup state across retries and restarts, and prevent
deletion from severing the lifecycle context of a live reusable sandbox.
**Alternatives considered:** Keep raw diagnostics in Test checks or
trust login URL text from the sandbox. Both choices increase information
exposure. Keep separate probe behavior in the ACP lane. That choice
would leave the two Test lanes inconsistent.
## What Changed
- Surface the sandbox login panel on both Test lanes.
- Reconcile the bundled Daytona plugin manifest so
`supportsSetupTokenLogin` reaches the UI capability gate.
- Prepare the ACP Test lane with the same probe runtime as the CLI Test
lane.
- Add the `claude_acp_login_probe_unavailable` warning when the ACP
probe cannot run.
- Send raw sandbox diagnostics only to redacted server logs.
- Keep Test checks on fixed public messages in the ACP, managed-config,
and CLI paths.
- Normalize login URL hints to allowlisted HTTPS Claude and Anthropic
hosts.
- Redact JSON and escaped-JSON secret values, including escaped quotes
and backslashes.
- Preserve orphan cleanup records across provider failures, restarts,
and unavailable plugins.
- Atomically block environment deletion while a live reusable sandbox
lease still depends on it.
- Verify pending cleanup destroys plugin sandboxes with the provider
configuration recorded on the lease, even after the current environment
configuration changes.
## Verification
- Head under review: `506b7fa2d83c36bfa5fd722ee9d95b0c7431c241`.
- Focused environment route/service/runtime coverage passes: 196 tests
across 3 files.
- `pnpm -r typecheck` passes.
- `pnpm build` passes.
- The full Vitest run completed with 4,754 passing and 28 failing tests.
All 23 source-test failures reproduce unchanged on parent head
`58cfe61a33191ce03d965d65085d26064b4888ba`; the other 5 are duplicate
executions from stale `server/dist` output. The failures are unrelated
macOS path/listener and scheduler-fixture failures, so there is no new
bad commit for bisect to localize.
- All required CI checks pass for the current head, including build,
typecheck/release registry, all server and workspace shards, serialized
server suites, canary, and e2e.
- A fresh Greptile review for `506b7fa2d83c36bfa5fd722ee9d95b0c7431c241`
reports 5/5, “safe to merge,” with no blocking failure remaining.
## Risks
- A probe or redaction change could hide useful server diagnostics.
- An allowlist change could reject a valid Claude login URL.
- Cleanup recovery changes could affect provider teardown ordering.
- An environment with a live reusable sandbox can no longer be deleted
until the owning issue or execution workspace completes teardown.
- The implementation keeps public Test messages fixed and sends detail
to redacted server logs.
## Model Used
OpenAI GPT-5 via Codex — exact model ID: GPT-5; tool use and code
execution enabled; extended reasoning enabled. The implementation author
used AI-assisted development.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandboxed agents use provider capabilities to select safe execution
paths
> - Session output still depends on three operator flags that duplicate
capability data
> - Duplicate flags can drift from the verified sandbox capability
snapshot
> - This pull request makes the capability snapshot the only streaming
decision and removes the obsolete flags
> - The benefit is default streaming with a poll fallback when a
capability or stream fails
## Linked Issues or Issue Description
**What existing behavior does this improve?**
ACP sandbox session-output streaming and sandbox execution
configuration.
**Subsystem affected**
Cross-cutting (multiple of the above): server/, packages/shared/,
packages/adapter-utils/, and packages/plugins/.
**Current behavior**
Session-output streaming requires operator flags in the server and
Daytona plugin configuration. Saved configurations can retain a removed
key.
**Proposed behavior**
The verified capability snapshot selects streaming. The Daytona plugin
uses persistent sessions by default, keeps bypass commands one-shot, and
falls back from the log stream to polling. Removed configuration keys
become inert.
**Reason and benefit**
One capability source prevents configuration drift. The fallback keeps
output available when capability resolution or log streaming fails.
**Breaking changes**
The three operator flags no longer control session-output streaming.
Existing saved keys load but have no effect.
## What Changed
- Remove `useSessions` and `useLogStream` from the Daytona plugin
configuration and manifest.
- Remove `streamAgentSessionOutput` from server configuration, shared
types, and execution-target plumbing.
- Select streaming from `persistentProcessSessions` and
`independentControlCommands`.
- Keep poll fallback on capability resolution failure and stream
failure.
- Strip removed keys from strict fake-sandbox and catchall plugin
configuration.
- Update the sandbox capability documentation and focused tests.
## Verification
- `tsc --noEmit` passed in `packages/shared`, `packages/adapter-utils`,
`server`, and the Daytona plugin.
- Daytona `plugin.test.ts` passed 139 tests.
- Server capability, configuration, route, and runtime suites passed 160
tests.
- `packages/adapter-utils` `execution-target-sandbox.test.ts` passed 44
tests.
- The capability matrix covers stream, poll, and resolution-failure
paths.
- Removed-key tests cover strict fake-sandbox and catchall plugin
schemas.
## Risks
- A capability snapshot that lacks either required session capability
uses polling.
- A log stream failure uses polling and can increase request count.
- Existing removed configuration keys no longer change behavior.
- The isolated-worktree Daytona Vitest run has a pre-existing missing
`packages/adapters/droid-local` reference. CI and standard checkouts use
the committed configuration.
## Model Used
OpenAI Codex, GPT-5, tool use and code review assistance. The exact
runtime context window is managed by the Codex platform.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip runs work through adapters and sandbox providers
> - Providers need a clear contract so the server can use only verified
capabilities
> - A declared capability must not grant a method that the live worker
did not verify
> - This pull request adds manifest declarations and fail-closed
effective capability resolution
> - The benefit is safe provider reuse across execution targets and run
lifecycles
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above)
**Problem or motivation**
Sandbox providers expose different runtime methods. The server needs one
safe capability contract that accounts for provider declarations, worker
verification, and narrowing configuration.
**Proposed solution**
Add strict manifest validation for five sandbox capabilities. Resolve
effective capabilities as the subset of verified, declared, and narrowed
values. Store the result as a frozen execution-target snapshot.
**Alternatives considered**
Trusting the manifest alone could grant methods that the worker does not
support. Trusting only a fixed built-in list would reject valid
third-party providers. The intersection rule keeps the verified runtime
ceiling and supports both provider types.
**Roadmap alignment**
This change supports the ACP run lifecycle track and the sandbox
provider contract work in the current roadmap.
**Additional context**
The legacy `supportsReusableLeases` field remains supported. The nested
capability validator rejects unknown keys. Missing or unavailable
verification resolves all capabilities to `false`.
## What Changed
- Add strict `sandboxCapabilities` manifest validation with legacy
reusable-lease compatibility.
- Carry declarations through the ready-driver projection.
- Add fail-closed effective resolution from verified, declared, and
narrowed capabilities.
- Add narrowing for provider configuration, Kubernetes Job leases, and
Daytona sessions.
- Add a frozen read-only capability snapshot to execution targets.
- Add focused tests and keep existing characterization baselines
covered.
- Add and update sandbox provider capability documentation.
## Verification
- `npx vitest run packages/shared/src/validators/plugin.test.ts`
- `npx vitest run
server/src/__tests__/plugin-environment-driver-sandbox-capabilities.test.ts`
- `npx vitest run
server/src/__tests__/sandbox-capability-contract.test.ts`
- `npx vitest run
server/src/__tests__/environment-execution-target-capabilities.test.ts`
- `npx vitest run
packages/adapter-utils/src/acpx-engine/startup-characterization.test.ts

packages/adapter-utils/src/acpx-engine/settlement-characterization.test.ts
packages/adapter-utils/src/acpx-engine/composed-run-characterization.test.ts`
- Package typechecks for shared, server, and adapter-utils pass.
- Stage-2 security review suites pass with 28 tests.
## Risks
The resolver fails closed when verification is absent or unavailable.
Providers that rely on undeclared capabilities may see narrower behavior
until they expose verified worker methods. The change does not alter the
existing native-sync guard.
## Model Used
OpenAI Codex, GPT-5, exact runtime model ID `gpt-5`, tool use and code
execution. The implementation author used this model to assist with the
change.

`execution-target-sandbox` has failed twice in CI and not once in several
hundred local runs. This does not fix it. It makes the next occurrence carry
its own evidence, because a third unreproducible failure would teach nothing.
The observed signature was an empty stdout with exit code 0 - the child exited
cleanly having produced nothing, which is what a lost stdin frame looks like
from the test's side. Three mechanisms were checked and ruled out rather than
assumed: the helper resolving on `exit` rather than `close` (a 200-iteration
probe produced no truncations, and the failure was empty rather than partial);
the wrapper reporting exit before stdout drains (it already listens on
`close`); and frame writes racing (the stream wrapper's `writeEvent` is
synchronous and sequence-numbered).
Two candidates remain and the runtime tree separates them. A stdin queue frame
still present means the host wrote it and the wrapper never consumed it; a
drained queue with no output means it was consumed and the reply was lost on
the way back. The report prints that tree, both proxy streams, the exit code,
and the elapsed time - the last because the bridge and proxy run on 5s budgets
that are generous locally and tight on a runner sharing a box with 19 other
lanes.
Timeouts are deliberately unchanged. Raising them would probably make the
symptom go away, which is the reason not to do it blind.
The first revision capped the tree walk one level above the queue frames, so
"the queue is empty" and "the walk never looked" printed identically - the
distinction the report exists to make. Caught in review. Verifying that the
reporter printed something was not enough; it had to print the thing that
discriminates, which is now checked by planting a frame and forcing the
assertion.
adapter-utils typecheck clean; 44 pass, stable across repeated runs.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter runtime starts, turns, settles, and composes ACPX runs

## Linked Issues or Issue Description
**What existing behavior does this improve?**
The ACPX adapter runtime and server heartbeat lifecycle need stable
regression coverage for their current corrected behavior.
**Subsystem affected**
Cross-cutting (multiple of the above): `packages/adapter-utils` and
`server` test suites.
**Current behavior**
The runtime has corrected rules for startup, turns, settlement, composed
results, and heartbeat terminalization. The repository lacks a single
characterization baseline for these rules.
**Proposed behavior**
Keep the current lifecycle rules pinned by five test suites. Let the
later engine refactor change behavior only when it updates these tests
with a clear reason.
**Reason and benefit**
The suites expose order, cleanup, transport, timeout, retry, result, and
lease-release changes during the refactor. They also record one known
latent defect as current behavior.
**Breaking changes**
None. This pull request adds tests only.
## What Changed
- Add startup characterization coverage for commands, launch values,
session fingerprints, sync order, bridge overlap, and cleanup paths.
- Add turn characterization coverage for inputs, events, transports,
timeout and cancel behavior, retry rules, errors, and usage.
- Add settlement characterization coverage for teardown, adapter
sync-back, workspace restore order, native sync, and error policy.
- Add composed-run characterization coverage for result forms,
finalization sets, and host-lane warm save and warm hit behavior.
- Add server coverage that checks run terminalization before environment
lease release.
## Verification
- Run `npx vitest run
packages/adapter-utils/src/acpx-engine/startup-characterization.test.ts
packages/adapter-utils/src/acpx-engine/turn-characterization.test.ts
packages/adapter-utils/src/acpx-engine/settlement-characterization.test.ts
packages/adapter-utils/src/acpx-engine/composed-run-characterization.test.ts
packages/adapter-utils/src/acpx-engine/execute.test.ts`.
- Run `npx vitest run
server/src/__tests__/heartbeat-run-terminalize-before-release.test.ts`.
- The adapter-utils run passes 178 tests, and the server run passes 4
tests.
- Check `pnpm --filter @paperclipai/adapter-utils typecheck`.
- Check `pnpm --filter @paperclipai/server typecheck`.
## Risks
Low risk. The change adds test files and does not change production
code. One known cold ensure-session cleanup defect remains pinned as
current behavior.
## Model Used
OpenAI Codex, GPT-5, with tool use and code execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters run ACP sessions and manage runtime, workspace, and
lease resources.
> - Several failure paths left runtime bridges, staged workspaces, or
environment leases active after an error.
> - These leaks reduce run reliability and can leave later runs without
clean resources.
> - This pull request closes the failure paths, applies one teardown
policy, and adds regression tests.
> - The benefit is consistent failure settlement and safer reuse of
agent workspaces and leases.
## Linked Issues or Issue Description
**What happened?**
ACP runs could leave runtime bridges, staged workspaces, or environment
leases active after failures. Claude and Gemini ACP runs did not restore
the sandbox workspace on teardown. Lease release stopped when one lease
returned an error.
**Expected behavior**
Each ACP failure must return an error result and settle its resources.
Teardown must run each step, release leases independently, and restore
the host workspace when the sandbox ends. Pending cleanup leases must
receive bounded retry attempts.
**Steps to reproduce**
1. Run an ACP session that fails after runtime creation or during turn
preparation.
2. Run an ACP session that fails during a warm hit or staged runtime
handoff.
3. Run lease cleanup with more than one lease when the first release
returns an error.
4. Inspect the result phase, teardown calls, workspace state, and lease
metadata.
5. Run the regression suites listed in the Verification section.
## What Changed
- Settle every ACP failure after runtime creation with an error result
and one sandbox.startup span closure.
- Close the ACP runtime and remove warm entries after every pre-turn
failure.
- Run all teardown steps, record teardown errors, release staging leases
in finally, and prevent duplicate teardown.
- Dispose staged runtimes after seam failures and remove borrowed staged
entries with identity guards.
- Add fail-open workspace sync-back teardown for Claude and Gemini ACP
adapters.
- Isolate lease release errors and add bounded retry sweeps for stranded
pending_cleanup leases.
- Atomically claim pending_cleanup retries and clamp attempt readers to
keep the five-attempt bound.
- Default absent provider reusableLeases values to false and align the
fake provider with its runtime declaration.
- Add regression tests for engine, adapter, server, and shared
environment behavior.
## Verification

## Risks
The engine changes affect failure settlement and teardown order across
ACP runs. The server changes add retry state to existing lease metadata
without a schema migration. The adapter changes restore workspaces after
sandbox execution. Regression tests cover the changed paths. GitHub CI
and Greptile passed for the current head.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. This change fixes runtime
reliability and does not duplicate a roadmap feature.
## Model Used
OpenAI GPT-5 Codex. The model used tool-based repository inspection,
GitHub operations, and code review support. The runtime does not expose
a context-window value.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters can run through a sandbox process-session bridge
> - The bridge writes streamed standard input to files before the remote
process reads them
> - Concurrent file writes can make a later chunk visible before an
earlier chunk

for the missing head
> - This pull request serializes host writes and makes an unexpected
file gap a loud error
> - The benefit is ordered input with a bounded failure path for sandbox
ACP sessions
## Linked Issues or Issue Description
No public GitHub issue exists for this change. The description below
follows `.github/ISSUE_TEMPLATE/bug_report.yml`.
**What happened?**
A sandbox ACP process-session bridge could stall after its handshake
when a run sent a large prompt. The host sent one un-awaited file write
for each standard input chunk. A small later chunk could finish before a
large earlier chunk. The remote poller then sent the tail bytes first.
The agent parser raised an error on the tail fragment, and the head
bytes stayed buffered without a newline.
**Expected behavior**
The bridge must expose standard input files in sequence. The remote
poller must report a clear error when an earlier file remains missing
beyond the retry budget.
**Steps to reproduce**
1. Start an ACP session through a sandbox process-session bridge.
2. Send a prompt that produces multiple standard input file chunks.
3. Delay finalization of an earlier chunk while a later chunk completes.
4. Observe that the remote parser can receive the later chunk first and
the session can stop without a clear error.
**Paperclip version or commit**
The change targets the current `master` branch at the submitted commit.
**Deployment mode**
The bug affects sandbox execution.
**Agent adapter(s) involved**
The failure affects the ACP process-session bridge.
**Database mode**
Not database-related.
**Additional context**
The fix keeps the existing per-file atomic write behavior. It adds
ordering at the host write boundary and a bounded ordering check in the
shared wrapper poll tail.
## What Changed
- Add a per-session promise chain for host standard input file writes.
- Keep a failed write from blocking later chain entries.
- Track the next expected sequence number in the shared wrapper poll
tail.
- Hold later files while an earlier file is missing within the existing
retry budget.
- Emit a loud error and advance after the retry budget expires.
- Add regression tests for host ordering, gap holding, and the loud
error path.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-stdin-race.test.ts` — 9
tests passed.
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts` — 43 tests
passed.
- `pnpm --filter @paperclipai/adapter-utils typecheck` — clean.
- With the source fix reverted, the 3 new tests fail and the 6 original
tests pass.
- CI must pass on the pull request before merge.
## Risks
Low risk.
- The host now serializes writes for each session, which can reduce
write parallelism.
- A failed write still emits one error and destroys the socket, as
before.
- The wrapper can emit a loud error after the existing retry budget when
a file gap persists.
- The change does not alter the atomic per-file write behavior.

and a sandbox

## Linked Issues or Issue Description
**What happened?**
The sandbox callback bridge could wait forever when a client call
stopped responding without a rejection.
**Expected behavior**
The bridge should fail queued requests and report a run-level error when
the sandbox channel stops responding.
**Steps to reproduce**
1. Start a sandbox callback bridge.
2. Queue a request.
3. Make the sandbox call stop responding.
4. Observe that the request does not receive a failure response.
**Paperclip version or commit**
Commit `edc4f71b460c600f97cf44cb486d5cac72ca2db9`.
**Deployment mode**
Built from source.
**Installation method**
Built from source with pnpm.
**Agent adapter(s) involved**
Custom or external sandbox callback bridge.
**Database mode**
Not database-related.
## What Changed
- Add a per-iteration timeout for `listJsonFiles` and
`processRequestFile`.
- Add a watchdog that fails pending requests when the loop makes no
progress.
- Abort a hung handler and use a non-retryable 504 backstop when its
outcome can be indeterminate.
- Retry recovery writes and keep queued requests when a recovery write
fails.
- Forward the indeterminate-outcome header through the execution target.
- Record worker failures through the
`sandbox.callbackBridge.workerFailed` trace span.
- Add tests for timeout, watchdog, recovery, mutation safety, header
forwarding, and fast-request behavior.
## Verification
- Run `pnpm exec vitest run
packages/adapter-utils/src/sandbox-callback-bridge.test.ts
packages/adapter-utils/src/execution-target-sandbox.test.ts`.
- Confirm that the PR test, typecheck, build, end-to-end, serialized
test, and security checks pass.
- Confirm that the current PR head is
`edc4f71b460c600f97cf44cb486d5cac72ca2db9`.
- Confirm that the PR changes four files: the callback bridge, its
tests, the execution target, and its tests.
## Risks
The default timeout can fail a slow but valid sandbox call. The defaults
remain configurable, and the iteration timeout stays below the sandbox
response deadline. A mutation that may have committed returns a
non-retryable 504 outcome so the caller does not apply it twice.
## Model Used
OpenAI Codex, GPT-5 current runtime, with extended reasoning and tool
use. The exact context window is not exposed by the runtime.

Fixes#2444.
Refs #4947.
The `claude_local` adapter launched Claude Code as
`claude --print - --output-format stream-json --verbose`. Paperclip writes
the rendered task prompt to Claude's stdin, but current Claude Code releases
can treat the stale `-` positional marker as the prompt itself, so Claude
received the literal string `"-"` instead of the issue body. The customer's
task ran against no content at all.
The fix keeps `--print` mode and stdin delivery, and removes the stale `-`.
Adds regression coverage on both sides of the delivery path: a `claude_local`
assertion that `--print` is present, `"-"` is absent and the prompt still
reaches stdin, and an adapter-utils case proving the sandbox run-log command
wrapper preserves stdin while streaming logs.
Authored by @elJayAdvisor, whose commit is included unchanged with their
authorship. The branch had gone stale and was showing CONFLICTING; the
conflict was in `execution-target-sandbox.test.ts`, where their new test was
added at the same point as master's `creates the process session directories
only in the launch exec` case and git interleaved the two into one hunk.
Resolved by taking master's file and re-inserting their test whole, after
checking every helper it needs still exists there.
Verified: the bug was still live on master at `execute.ts:838`; the
regression test genuinely catches it — restoring the stale `-` fails
`expect(captured.argv).not.toContain("-")`; `@paperclipai/adapter-claude-local`
and `@paperclipai/adapter-utils` typecheck clean; 67 pass across the two test
files. All CI gates green; Greptile 5/5.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Reviewers annotate plans and issue documents with inline comments,
and assigned agents act on that feedback
> - The server already builds a bounded review context from open plan
annotations and includes it in agent wake payloads
> - Non-plan issue documents did not get the same treatment: their open
annotation threads never reached the agent, and the properties pane did
not surface their annotations
> - This pull request extends the review-context path and the
properties-pane UI to issue documents, at parity with plans
> - The benefit is that agent feedback on any issue document reaches the
assigned agent, not only feedback on the plan
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The review-context pipeline that delivers inline annotation feedback to
assigned agents, and the properties pane that surfaces those annotations
to reviewers.
**Subsystem affected**
The server review-context path
(`server/src/services/plan-review-context.ts`, wake payload assembly in
`server/src/services/heartbeat.ts`, `server/src/routes/issues.ts`),
shared wake-payload types (`packages/shared`, `packages/adapter-utils`),
and the issue properties pane (`ui/src/components/issue-properties/`).
**Current behavior**
A reviewer can annotate any issue document, not only the plan. The agent
wake payload includes open annotation threads for the plan document
only. Feedback left on other issue documents is invisible to the
assigned agent. In the properties pane, the Artifacts tab also gives no
way to see or open a document's annotations.
**Proposed behavior**
Add `buildDocumentReviewContext` beside the existing plan builder. It
collects open annotation threads for all non-plan issue documents,
applies the same thread, comment, and character budgets across
documents, and reports truncation. Include the result as a new
`documentReviewContext` field in agent wake payloads and in the issue
wake-context route. Keep the plan context on its legacy builder and
field so plan-only wakes stay byte-for-byte compatible. Render the new
context in the adapter wake-payload text, and surface annotation counts
and the annotation panel for documents in the properties pane's Plans
and Artifacts tabs.
**Reason and benefit**
The floating annotation popover and persistent highlight UI landed
earlier; this change completes the loop so agent feedback on any issue
document reaches the assigned agent, not only feedback on the plan.
**Breaking changes**
None. The wake payload gains a new optional `documentReviewContext`
field; the existing plan context field and its legacy builder are
unchanged, so plan-only wakes stay byte-for-byte compatible.
## What Changed
- Add `buildDocumentReviewContext` in
`server/src/services/plan-review-context.ts`: bounded review context
(shared thread/comment/character budgets, per-document legacy limits)
over all non-plan issue documents
- Include `documentReviewContext` in agent wake payloads
(`server/src/services/heartbeat.ts`) and in the issue wake-context
response (`server/src/routes/issues.ts`)
- Add shared `DocumentReviewContext` / `DocumentReviewContextDocument`
types in `packages/shared`
- Normalize and render the new context in adapter wake-payload text
(`packages/adapter-utils/src/server-utils.ts`), with tests
- Show a `DocumentAnnotationsCountChip` and the annotation panel for
documents in the properties pane Plans and Artifacts tabs, with tests
- Extend server document-annotations service tests to cover the new
context builder
## Verification
- Run `npx vitest run packages/adapter-utils/src/server-utils.test.ts
server/src/__tests__/document-annotations-service.test.ts` from the repo
root — 104 tests pass
- Run `TZ=UTC npx vitest run
ui/src/components/issue-properties/IssuePropertiesDocumentAnnotations.test.tsx
ui/src/components/IssueProperties.test.tsx
ui/src/components/IssueDocumentAnnotations.test.tsx
ui/src/components/DocumentAnnotationPopover.test.tsx` from the repo root
— 75 tests pass (one pre-existing monitor-row case asserts UTC
timestamps, so use `TZ=UTC` locally; CI runs in UTC)
- `pnpm run typecheck` in `server/` passes
- Manual: annotate a non-plan issue document, then wake the assigned
agent with a comment — the wake payload lists the open document
annotation threads; the Artifacts tab shows the annotation count chip
and opens the panel
## Risks
- The wake payload gains a new optional `documentReviewContext` field;
consumers that ignore unknown fields are unaffected, and the plan
context field is unchanged
- The context is new input to agent wakes; shared budgets (same limits
as the plan context) bound token cost across all documents
- Low UI risk: the properties-pane changes reuse the existing annotation
components

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Every agent run gets a run-scoped bridge into the Paperclip API
through the injected `PAPERCLIP_API_URL` / `PAPERCLIP_API_KEY` env vars,
built by `buildPaperclipEnv` in
`packages/adapter-utils/src/server-utils.ts`
> - `buildPaperclipEnv` resolves that URL as `PAPERCLIP_RUNTIME_API_URL
?? PAPERCLIP_API_URL ?? http://<listen-host>:<port>`, and the server
always exports `PAPERCLIP_RUNTIME_API_URL` derived from
`authPublicBaseUrl` at boot
> - When `authPublicBaseUrl` points at an address that is not reachable
from inside the runtime container (e.g. a VPN/tailnet-only address used
to keep the web UI off the public internet), every local run receives a
dead API URL (`curl` exit 7) and agents only survive by hand-rolling a
localhost fallback
> - An operator-set `PAPERCLIP_API_URL` is the documented escape hatch —
`docs/deploy/environment-variables.md` states the server "preserves the
value" when set externally and that the run-level var "inherits the
server-level value" — but the run env builder inverts the precedence, so
the override never actually reaches runs
> - This pull request swaps the precedence in `buildPaperclipEnv` so an
explicit `PAPERCLIP_API_URL` wins over the derived runtime URL, aligning
the behavior with the documented contract
> - The benefit is that operators with split-horizon topologies (public
auth URL != container-reachable URL) can point agent runs at a reachable
endpoint with one env var, with zero behavior change for deployments
that do not set it
## Underlying Issue
No pre-existing public issue covers this, so per CONTRIBUTING ("Link
Issues or Describe Them In-PR") here are the `bug_report.yml` fields
inline:
- **What happened:** with `PAPERCLIP_AUTH_PUBLIC_BASE_URL` on a
tailnet-only address and `PAPERCLIP_API_URL=http://localhost:3100`
explicitly set in the server environment, every agent run still received
`PAPERCLIP_API_URL=http://100.x.y.z:3100` (the derived,
container-unreachable URL); `curl` from inside the run exits 7 and
agents can only reach the API by hand-rolling a localhost fallback
- **Expected behavior:** the run env inherits the operator-configured
`PAPERCLIP_API_URL`, as documented in
`docs/deploy/environment-variables.md` ("preserves the value", run-level
var "inherits the server-level value")
- **Steps to reproduce:** (1) set `PAPERCLIP_AUTH_PUBLIC_BASE_URL` to an
address not reachable from inside the server container, (2) set
`PAPERCLIP_API_URL=http://localhost:3100` in the server env, (3) trigger
any agent run and inspect the spawned process env: it carries the
derived URL, not the override
- **Version/commit:** reproduced on the `91e58acb` image (2026-07-19);
the precedence is unchanged on current `master` (`a3b293e`)
- **Deployment mode:** single-host Docker Compose, local adapters
(`claude_local`/`codex_local`), web UI exposed via VPN/tailnet only
## Related PRs (dedup search)
Several in-flight PRs touch the same pain point (runs receiving an
unreachable injected API URL) — linked for reviewer context; none of
them honors the documented explicit override, and the older ones appear
stale:
- #9916 — reworks `PAPERCLIP_RUNTIME_API_URL` derivation and port
preservation (server side); complementary, does not change run-env
precedence
- #8130 — honors a pre-set `PAPERCLIP_RUNTIME_API_URL` (server side); a
complementary escape hatch via the runtime var instead of the documented
`PAPERCLIP_API_URL` override
- #8025 — heuristic: prefer loopback when the runtime bind is loopback
(no activity since Jun 12)
- #5692 — heuristic loopback-safe URL inside `buildPaperclipEnv` (no
activity since May 14)
- #4877 — broader same-host injection rework across 10 files (no
activity since May 2)
- #4794 — always forces loopback for spawned agents (no activity since
Apr 30; would break split-horizon setups where a reachable non-loopback
URL is intended)
This PR intentionally takes the Path-1 route from CONTRIBUTING: the
smallest possible change (swap two lines so the documented operator
override wins) plus regression tests, rather than a new heuristic.
## What Changed
- `packages/adapter-utils/src/server-utils.ts`: `buildPaperclipEnv` now
resolves the injected URL as `PAPERCLIP_API_URL ??
PAPERCLIP_RUNTIME_API_URL ?? http://<listen-host>:<port>` (explicit
override first), with a short comment explaining why
- `packages/adapter-utils/src/server-utils.test.ts`: three new tests
covering the override precedence, the derived-URL fallback, and the
listen-host default (including the `0.0.0.0` to `localhost` mapping)
- `server/src/__tests__/paperclip-env.test.ts`: updated the expectation
that encoded the old runtime-URL-first precedence and added the
symmetric fallback case (runtime URL used when no explicit override is
set)
- No docs changes needed: `docs/deploy/environment-variables.md` already
describes the fixed behavior
## Verification
- `vitest run` on the new `buildPaperclipEnv` tests in
`packages/adapter-utils`: 3/3 pass
- `vitest run` on `server/src/__tests__/paperclip-env.test.ts` after the
expectation update: 5/5 pass (the first CI run correctly flagged the one
test that encoded the old precedence)
- Reproduced and verified on a production deployment (single-host
Docker, `PAPERCLIP_AUTH_PUBLIC_BASE_URL` on a tailnet-only address):
- Before: freshly spawned runs received
`PAPERCLIP_API_URL=http://100.x.y.z:3100` (verified in the spawned
process `/proc/<pid>/environ`); `curl` to it from inside the container
exits 7
- After (with `PAPERCLIP_API_URL=http://localhost:3100` in the compose
environment): a fresh run received `http://localhost:3100`, and `curl
$PAPERCLIP_API_URL/api/agents/me` with the run-scoped key returned HTTP
200; the run finished `succeeded` with usage telemetry recorded
## Risks
- Low. Behavior changes only for deployments that explicitly set
`PAPERCLIP_API_URL`; when unset (the default),
`PAPERCLIP_RUNTIME_API_URL` is used exactly as before
- The sandbox callback bridge (`execution-target.ts`) is intentionally
untouched: remote sandboxes genuinely need the publicly reachable URL,
and its `input.hostApiUrl || PAPERCLIP_RUNTIME_API_URL || ...` chain
still provides it

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents can execute in remote sandboxes, where a callback bridge
relays in-sandbox Paperclip API calls back to the host server process
> - The bridge worker resolves its forward target from
PAPERCLIP_RUNTIME_API_URL / PAPERCLIP_API_URL, which now prefer a
configured public base URL and therefore mean "the origin browsers and
external agents use"
> - The bridge worker runs inside the same process that serves the API,
so forwarding through the public origin routes an in-process loopback
hop through the network edge
> - On a deployment whose public origin sits behind a session-gated edge
proxy, every forwarded agent API call is rejected at the edge, so agents
in sandboxes cannot read their identity, comment, or hire
> - This pull request resolves the bridge forward target from the
explicit hostApiUrl override or the local listen host and port only,
never the public URL exports
> - The benefit is that sandbox agent API calls keep working regardless
of how the public base URL is configured or gated
## Linked Issues or Issue Description
No existing issue. Describing in-PR following the bug report template:
**What happened?**
On a cloud deployment with a session-gated public edge, setting a public
base URL (PAPERCLIP_PUBLIC_URL) caused every in-sandbox agent API call
through the sandbox callback bridge to fail with `403 text/plain "Access
denied"` from the edge proxy. With PAPERCLIP_BRIDGE_DEBUG enabled, the
bridge logs show the forward target is the public origin, and every
proxied request (for example `GET /api/agents/me`) returns the edge
proxy's 403 instead of reaching the API.
**Expected behavior**
The bridge worker runs in the same server process that serves the API,
so forwarded calls should target the local listen origin and succeed
regardless of how the public origin is configured or gated.
**Steps to reproduce**
1. Run the server with a public base URL configured, fronted by a proxy
that requires a browser session on API routes.
2. Start a sandbox-executed agent run (any adapter using the sandbox
callback bridge).
3. Observe every in-sandbox call to the Paperclip API fail with the
proxy's 403; with PAPERCLIP_BRIDGE_DEBUG the forward URL is the public
origin.
**Paperclip version or commit**
Current `master`.
**Deployment mode**
Self-hosted server behind a reverse proxy.
**Agent adapter(s) involved**
All sandbox-executed adapters (the bridge is adapter-agnostic).
## What Changed
- `packages/adapter-utils/src/execution-target.ts`:
`startAdapterExecutionTargetPaperclipBridge` now resolves its forward
target as `input.hostApiUrl?.trim() || resolveDefaultPaperclipApiUrl()`.
It no longer consults `PAPERCLIP_RUNTIME_API_URL` / `PAPERCLIP_API_URL`,
which now describe the public origin for browsers and external agents,
exactly the wrong target for an in-process loopback hop.
`resolveDefaultPaperclipApiUrl()` builds
`http://<PAPERCLIP_LISTEN_HOST>:<PAPERCLIP_LISTEN_PORT>` (exported by
server boot before any run executes) and maps wildcard listen hosts to
the loopback address of the same family (`0.0.0.0` to `127.0.0.1`, `::`
to `[::1]`), so the forward target always matches the address family the
server is bound to. `input.hostApiUrl` remains the explicit override
seam. A comment documents the reasoning.
- `packages/adapter-utils/src/execution-target-sandbox.test.ts`: two new
tests. One sets both public URL env vars to an unreachable public https
origin and asserts the bridge forwards to the local listen origin (fails
before this fix with a 502 because the worker targets the public
origin). One asserts an explicit `hostApiUrl` input still overrides
everything.
- The acpx-engine bridge start
(`packages/adapter-utils/src/acpx-engine/execute.ts`) passes no
`hostApiUrl` and goes through the same resolution site, so it is covered
by the same fix. The sandbox-facing env builder in `server-utils.ts` is
intentionally untouched; the bridge env overrides `PAPERCLIP_API_URL`
inside the sandbox separately.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts` (28 tests
pass; the new local-origin test fails without the fix)
- `pnpm --filter @paperclipai/adapter-utils typecheck` (clean)
- Full adapter-utils suite run; the only failures are pre-existing
environment-dependent tests (bubblewrap and shallow-clone tests on
macOS) identical on a clean `master` checkout
## Risks
- Low risk. Deployments where the bridge previously worked did so
precisely because the forward target already resolved to the local
origin (no public URL configured, so the chain fell through to the same
`resolveDefaultPaperclipApiUrl()` result). The only behavioral shift is
for deployments with a public URL configured, where forwarding through
the edge was either wasteful (an unnecessary network round trip) or
broken (session-gated edge). The explicit `hostApiUrl` override seam is
preserved for callers that need a nonlocal target.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - It runs each agent in a remote sandbox and emits OpenTelemetry spans
for the sandbox bring-up and the run.
> - A real trace showed two gaps. `stage.sync` had about 3 seconds of
unattributed host work before its `pack` span. The persistent agent
process showed a `sandbox.exec` span that outlived its parent by about
50 seconds.
> - The gaps hide real cost and make the trace read as a sequencing bug,
so an operator cannot see where startup time goes.
> - This pull request wraps the two pre-`pack` host steps in their own
spans. It also homes the long-lived process in a run-scoped
`sandbox.agentProcess` span.
> - The benefit is that startup time is fully attributed and the process
reads as a resource that overlaps the turn, not a child that outlives
its parent.
## Linked Issues or Issue Description
No public issue exists. This is an enhancement to existing telemetry. It
is described inline below, following
`.github/ISSUE_TEMPLATE/enhancement.yml`. Prior related work: the merged
PR #10999 added the run-time wrapper spans and the telemetry
data-contract section this PR extends.
**What existing behavior does this improve?**
The sandbox bring-up and run OpenTelemetry trace. It closes two
attribution gaps in that trace.
**Subsystem affected**
Observability for sandbox execution. The code lives in
`packages/adapter-utils`. The span contract lives in
`packages/shared/src/telemetry`.
**Current behavior**
`stage.sync` opens a `pack` span, but the git enumeration and the
baseline content-hash walk that run before `pack` have no span, so about
3 seconds read as a gap. On the streamed process-session path the agent
process launches fire-and-forget inside the ~2.3 second
`bridge.process-session` bring-up step, so its `sandbox.exec` span
parents to that step and then runs about 50 seconds. The child dangles
past its parent and overlaps `agent.turn`.
**Proposed behavior**
Wrap the two pre-`pack` host operations in `snapshot.git` and
`snapshot.baseline` spans under `stage.sync`. Wrap the streamed launch
in a run-scoped `sandbox.agentProcess` span that parents to the live run
root (`task.run` at launch).
**Reason and benefit**
Startup time is fully attributed. The long-lived process reads as a
resource that overlaps the sibling `agent.turn`, not a mis-parented
child.
**Breaking changes**
None. The spans are opt-in and export only when an OTLP endpoint is
configured. The span seam is a no-op when no runner is injected. No
first-party telemetry event changes.
## What Changed
- `sandbox-managed-runtime.ts`: add `snapshot.git` and
`snapshot.baseline` spans around the git enumeration and the baseline
content-hash walk, nested under `stage.sync`, through a shared
`runStepSpan` helper that `pack` now also uses.
- `execution-target.ts`: wrap the fire-and-forget streamed launch in a
run-rooted `sandbox.agentProcess` span, so it parents to the live run
root and holds the inner `sandbox.exec`. The `.then`/`.catch` chain
became try/catch inside the span callback, with identical
frame-ingestion behavior.
- `packages/shared/src/telemetry/README.md`: update the span table and
the parenting prose. Add `snapshot.git`, `snapshot.baseline`, `pack`,
and `sandbox.agentProcess`, and document the intended
`sandbox.agentProcess` / `agent.turn` overlap.
- Tests: update the executor span-tree test (`childNames` and parent
assertions), update the `sandbox-managed-runtime` span-set and nesting
tests, and add two `execution-target-sandbox` tests (the launch opens
`sandbox.agentProcess`; it parents to the run root, not the bring-up
step).
## Verification
- Run `npx vitest run` on the three affected test files. Result: 174
tests pass. This includes the updated executor span-tree test and the
new `sandbox.agentProcess` open and parenting tests.
- Run `tsc --noEmit` in `packages/adapter-utils`. Result: no errors in
the changed source or test files.
- The full 37-test streamed process-session suite passes unchanged. This
confirms the try/catch restructure preserves frame delivery and
exit/error behavior.
- Pre-existing and unrelated to this PR (present on `master`): `tsc`
errors in `execute.ts` / `execute.test.ts` /
`remote-spawn-smoke.test.ts` (`onAgentStderr` / `spawnCwd`), and a
`check:forbidden-tokens` failure from internal `PAP-###` ids in
`ui/src/components/IssueRecoveryActionCard.test.tsx`. This PR does not
touch those files, and its own diff is token-clean.
## Risks
Low. The change adds instrumentation on the opt-in span path and does
not change control flow on the default path. The one production
restructure is the streamed launch, which stays fire-and-forget, so
bring-up does not block on it. Only the streamed path gains
`sandbox.agentProcess`; the legacy poll path launches the process
detached and has no host-side long-lived span to home.
## Model Used
Anthropic Claude Opus 4.8 (`claude-opus-4-8`), about 200K-token context,
agentic tool use through Claude Code. The trace was reviewed through the
Honeycomb MCP. The code was written and tested with the model.

secret delivery, redaction, and fail-closed transport checks, ready for
a later staged production rollout
## Linked Issues or Issue Description
**Agent or provider**
Claude Code setup-token login for sandbox agents.
**Why this adapter is useful**
Sandbox agents need a supported way to sign in without host credentials.
An authorized owner completes the browser step and receives the token
one time.
**How the agent is invoked**
When a sandbox provider binds the injectable transport, the server
starts `claude setup-token` through a sandbox pseudo-terminal, sends the
browser code to the matched prompt, and returns the token through the
guarded session route. The default build does not bind the transport. In
that state the start route fails closed with a fixed no-secret `503`. It
does not start a process and it does not hold a sandbox lease.
**Additional context**
The transport is injectable, so each sandbox provider binds its own
pseudo-terminal. This pull request adds the Daytona transport but does
not bind it in the production server. A production wiring needs a lease
manager, a live pseudo-terminal factory, a durable token store, and its
own security review. The route keeps secrets out of logs, activity
details, errors, telemetry, and non-owner responses.
## What Changed
- Add strict parsers for the setup-token URL, the prompt, and the
success token.
- Add a login runner that drives the `claude setup-token` command
through a pseudo-terminal.
- Add the Daytona pseudo-terminal transport and the sandbox plugin
wiring.
- Add a company-scoped, owner-bound login session service with rate
limits, a reaper, cleanup, and one-time token delivery.
- Add the guarded session routes at
`/agents/:id/setup-token-login-sessions/*` behind an injectable
transport. The routes become the live login path only when a provider
binds the transport.
- Keep the start route fail-closed in the default build. It returns a
fixed no-secret `503` and it does not bind `setupTokenLogin`.
- Keep the existing host route `POST /agents/:id/claude-login` in place.
This pull request does not replace it.
- Keep confidential responses behind a fail-closed TLS transport guard
with `Cache-Control: no-store`, and extend redaction for the new fields.
- Export the parser and the runner from the Claude local server entry,
and document the new session routes in the OpenAPI spec.
## Verification
- `pnpm --filter @paperclipai/server exec vitest run setup-token-route
setup-token-session`
- `pnpm --filter @paperclipai/adapter-claude-local exec vitest run`
- `pnpm --filter @paperclipai/server run typecheck`
- Confirm that the pull request checks pass on GitHub.
## Risks
- Low user-facing risk on merge. The default build does not bind the
transport, so the production start route stays fail-closed with a `503`.
The merge does not change the production login behavior.
- When a provider later binds the transport, the flow starts a live
sandbox process and holds a short-lived in-memory secret. Cleanup must
stop the child before it releases the sandbox lease.
- The transport guard fails closed when the deployment does not provide
a trusted TLS path. A wrong proxy allowlist can block a valid request.
- The production wiring is out of scope. It needs a lease manager, a
live pseudo-terminal factory, a durable token store, and its own
security review before the server binds `setupTokenLogin`.
## Model Used
Anthropic Claude Opus 4.8 assisted the implementation. It used extended
reasoning, code execution, repository tool use, and a 200,000-token
context window.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use execution targets to exchange input and output
with sandbox processes
> - The sandbox input path can expose partial files, and the poller can
delete or stop on invalid input
> - These timing windows can lose agent input without a clear error
> - This pull request makes host writes atomic and makes the poller
retry invalid files before it drops them
> - The benefit is reliable sandbox input delivery with visible failure
after bounded retries
## Linked Issues or Issue Description
Closes#10874
## What Changed
- Decode host input into a temporary file, then rename it onto the final
JSON path.
- Apply the same atomic write pattern to the filesystem client.
- Parse each input file before deletion.
- Retry parse failures and drop a file after the bounded retry limit
with an error event.
- Add regression tests for empty, partial, and permanently malformed
input files.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/execution-target-stdin-race.test.ts` passes
5/5 tests.
- Related sandbox callback, execution target, and sandbox execution
suites pass 71/71 tests.
- TypeScript checks pass for the changed files.
- The regression suite fails on the old code and passes on this change.
## Risks
- Low risk. The change affects sandbox input file handling and adds
bounded retry behavior.
- A permanently malformed file now creates an error event after the
retry limit.
> This bug fix does not add a core feature, so a roadmap change is not
needed.

## Thinking Path
> - Paperclip runs AI agents through adapter execution services.
> - The adapter runtime records spans for each stage of agent startup.
> - The managed runtime packs workspace tarballs before it uploads them.
> - These pack operations had no host span, so `stage.sync` omitted pack
time.
> - This pull request adds one `pack` span around both tarball builds.
> - The span nests under the active `stage.sync` step and improves trace
detail.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The managed runtime workspace sync builds a git-history tarball and a
workspace-overlay tarball before upload.
**Subsystem affected**
The change affects `packages/adapter-utils`, which provides adapter
execution and managed runtime support.
**Current behavior**
The host builds both tarballs without an OpenTelemetry span. The
`stage.sync` trace therefore omits the host pack duration.
**Proposed behavior**
The host wraps both tarball builds in one `pack` span. The executor
parents this span under the active startup step.
**Reason and benefit**
The trace shows the time that the host spends packing workspace data.
Operators can use the existing runtime span tree to find sync delays.
**Breaking changes**
None. The default span runner remains a no-op runner, and the existing
control flow remains unchanged.
## What Changed
- Add an optional `runtimeSpan` runner to the managed runtime
preparation path.
- Create one host `pack` span around the two workspace tarball builds.
- Parent the `pack` span under the active startup step.
- Add unit coverage for span emission and span nesting.
## Verification
- Run `tsc --noEmit` for `@paperclipai/adapter-utils`.
- Run the `@paperclipai/adapter-utils` Vitest suite.
- Confirm the suite reports 448 passed tests and 4 skipped tests.
- Confirm the trace test records `pack` under `stage.sync`.
## Risks
The change adds optional tracing only. The default no-op runner
preserves behavior when tracing is not configured.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. The model reviewed the
handoff and opened this pull request. The implementation author supplied
the commit.

## Thinking Path
> - Paperclip is the open source app that manages AI agents for work
> - Sandbox providers let agents run in remote and isolated environments
> - Daytona session commands need a path that sends agent output to the
host without host polling
> - Host polling adds delay and repeats provider output work
> - This pull request adds typed execute.log notifications and a log
sink for incremental output
> - This pull request adds an optional ACP session stream with
final-result replay protection
> - The benefit is lower output delay while the default flags keep
current behavior unchanged
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. The change spans the plugin SDK, Daytona provider,
adapter utilities, and server execution services.
**Problem or motivation**
The Daytona ACP bridge polls a host output file while an agent command
runs. This adds delay and can repeat work. The host also needs a safe
route for provider output chunks.
**Proposed solution**
Add a typed `execute.log` notification with host-issued invocation
correlation. Add an ordered log sink to the environment execute path.
Add an optional ACP session-log path that parses newline-delimited JSON
frames and removes the host output poll for that path.
**Alternatives considered**
Keep the output-file poll as the only path. This keeps the current
behavior but does not provide timely output. The new path stays behind
flags, so the existing path remains the default fallback.
**Roadmap alignment**
This change supports the shipped Cloud / Sandbox agents milestone in
`ROADMAP.md`, including Daytona support.
## What Changed
- Add the typed `execute.log` worker-to-host notification and
company-scoped host route.
- Add ordered `stdout` and `stderr` chunk delivery before the final
execute result.
- Add the Daytona session log sink and the optional ACP streamed session
path.
- Add monotonic frame handling so live and final output reach the host
once.
- Keep `useLogStream` and `streamAgentSessionOutput` off by default.
- Add unit and integration coverage for the notification, execution
target, runtime, and Daytona paths.
## Verification
- Run adapter-utils tests: 445 tests pass locally.
- Run server environment tests: 73 tests pass locally.
- Run Daytona plugin tests: 131 tests pass locally.
- Run TypeScript checks for shared, adapter-utils, and server.
- Review the pull request checks after GitHub completes them.
- All required GitHub checks pass on the current head.
## Risks
The new paths change output delivery only when a feature flag enables
them. The final execute result remains available for parsing and
fallback. The main risk is a provider stream or frame-order error; the
final-result parser limits that risk.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. The runtime did not
supply a context-window value.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip uses adapter and sandbox code to start agents and run
sandbox work
> - The current sandbox spans use mixed names and do not group related
run-time work
> - Mixed names make traces harder to read and compare across providers
> - This pull request renames provider spans, adds run-time wrapper
spans, and keeps the host allowlist closed
> - The benefit is clearer traces with the same sandbox behavior and
trust boundary
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves OpenTelemetry span names and grouping for sandbox startup,
execution, callback relay, and agent session work.
**Subsystem affected**
Cross-cutting (multiple of the above): adapter utilities, sandbox
providers, shared telemetry documentation, and server instrumentation.
**Current behavior**
Sandbox provider spans use mixed names. Related run-time operations
expose inner `sandbox.exec` spans without a named wrapper span. The host
mapper uses a closed allowlist for provider span names.
**Proposed behavior**
Use descriptive provider-scoped span names. Add wrapper spans for agent
session input, agent session output polling, and callback relay. Keep
the host mapper allowlist closed and map unknown names to `other`.
**Reason and benefit**
Clear names make traces easier to read and reduce ambiguity during
sandbox operation analysis. Wrapper spans show the full operation while
preserving the inner execution spans.
**Breaking changes**
None. This change updates telemetry span names and grouping only. It
does not change sandbox behavior, endpoint behavior, or the host trust
boundary.
**Additional context**
Related prior work:
[#10758](https://github.com/paperclipai/paperclip/pull/10758).
## What Changed
- Rename Daytona provider sync and session spans with descriptive
provider-scoped names.
- Add three run-time wrapper spans for agent session input, output
polling, and callback relay.
- Add a shared span runner that preserves no-op behavior without a real
tracer.
- Keep the host mapper allowlist closed and map unknown names to
`other`.
- Update telemetry documentation and span-name tests.
## Verification
- Focused adapter-utils span tests pass for startup timing, callback
relay, and sandbox execution.
- Focused Daytona plugin span tests pass for renamed leaf spans and
session open or close spans.
- Focused server tests pass for host mapping and instrumentation.
- The stacked diff contains one commit on top of
`feat/daytona-persistent-session-model`.
## Risks
- Span names change for existing telemetry consumers.
- The wrapper spans add trace structure but do not change sandbox
execution.
- The host mapper keeps the existing closed allowlist and `other`
bucket.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents ask humans for decisions through interaction blocks: plan
confirmations, structured questions, suggested tasks, and checkbox
prompts
> - Each agent writes these decision prompts in its own style, so
operators can get long or unclear text at the exact moment they must
decide
> - There is no instance-level control that makes agents use a
controlled language for these decision points only
> - This pull request adds an experimental setting that tells agents to
write all user-interaction content in ASD-STE100 Simplified Technical
English, with the context the user needs and the effect of each choice
> - The benefit is faster, clearer human decisions, with agent thinking
and normal responses unchanged
## Linked Issues or Issue Description
Refs #10410 (optional `/simplified-english` skill in the skills catalog;
this PR adds the instance-level toggle for interactions).
**Problem or motivation**
Agent-posted user interactions (plan confirmations, structured
questions, suggested-task proposals, checkbox prompts) are written in
each agent's default style. Operators who want fast, unambiguous
decisions have no way to ask agents to use a controlled language for
exactly those decision points.
**Proposed solution**
Add an experimental instance setting,
`enableSimplifiedEnglishInteractions` ("Simplified English
Interactions"). When it is on, the server sets
`simplifiedEnglishInteractions: true` in the heartbeat wake payload. The
shared wake-prompt renderer, used by every adapter, then emits a
directive: write all user-interaction content in ASD-STE100 Simplified
Technical English, state what information the user needs to decide, and
state what happens for each choice. The directive applies to interaction
content only. Thinking, comments, documents, and other responses keep
their usual style.
**Alternatives considered**
Per-agent instructions work today, but someone must maintain them on
every agent. An instance-level toggle applies uniformly and turns off in
one place. Server-side rewriting of interaction payloads was rejected:
post-hoc translation is lossy and cannot add the decision context that
only the agent has.
**Roadmap alignment**
Extends the experimental settings surface with another opt-in
agent-behavior refinement, consistent with existing prompt-side flags.
## What Changed
- Added `enableSimplifiedEnglishInteractions` to the experimental
instance-settings zod schema, mirror type, and feature catalog (default
off, tier preference) in `packages/shared`.
- Server `instance-settings.ts` normalizes the flag on both read
branches; `heartbeat.ts` reads it once and passes
`simplifiedEnglishInteractions` into `buildPaperclipWakePayload`.
- Shared adapter renderer
(`packages/adapter-utils/src/server-utils.ts`): added the field to
`PaperclipWakePayload`, normalization, and an `- interaction language
(experimental): ...` directive emitted in both fresh and resume prompt
lanes, so one injection point covers all adapters.
- UI: new experimental settings card "Simplified English Interactions"
in `ui/src/pages/InstanceExperimentalSettings.tsx`, in alphabetical card
order; fixtures updated.
- Tests: renderer coverage for flag on/off in both lanes, plus
schema/catalog/UI fixture updates.
## Verification
- From the repo root: `node_modules/.bin/vitest run
packages/adapter-utils` (88/88), `packages/shared` validators (25/25),
server instance-settings + heartbeat suites (47/47 and 70/70 consumer
tests), `ui` settings tests (32/32).
- Typecheck is clean in all four touched packages.
- Manual check: turn the flag on in Settings → Experimental, wake an
agent, and confirm the wake prompt contains the interaction-language
directive; turn it off and confirm the directive is absent.
## Risks
- Low risk: the flag defaults to off, and the only behavior change is
one extra directive line in the wake prompt when an operator turns it
on.
- The directive is advisory to the agent; models can still deviate from
STE. No data or API shape changes; no migration.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The agent Test action builds adapter config from the form.
> - The build-config parser kept plain and secret_ref bindings.
> - It dropped user_secret_ref bindings on the create path.

## Linked Issues or Issue Description
**What happened?**
The agent Test action dropped a user-scoped env binding in create mode.
The same agent config worked in a real run. Related public PRs: #10115,
#9321, #9921, #8825.
**Expected behavior**
The Test action should keep user-scoped env bindings and resolve them
like a real run.
**Steps to reproduce**
1. Set a user-scoped env binding on an agent config form.
2. Run Test in create mode.
3. The probe runs without the variable.
**Paperclip version or commit**
c09d2509e3
**Deployment mode**
Local dev (pnpm dev)
**Agent adapter(s) involved**
Not adapter-specific (core bug)
**Database mode**
Embedded PGlite (default — DATABASE_URL unset)
**Additional context**
This change is not Claude-specific.
## What Changed
- Added a shared env binding parser in `@paperclipai/adapter-utils`.
- Replaced the eight adapter build-config copies with the shared helper.
- Kept `plain`, `secret_ref`, and `user_secret_ref` bindings intact in
create mode and edit mode.
- Preserved the runtime merge behavior from the earlier env merge
change.
## Verification
- Author-recorded test run:
`packages/adapter-utils/src/env-bindings.test.ts`
- Author-recorded test run:
`packages/adapters/claude-local/src/ui/build-config.test.ts`
- Author-recorded test run: six adapter build-config test files
- Author-recorded typecheck: `tsc --noEmit` for adapter-utils and the
eight adapter packages
- GitHub checks: all required PR checks pass on PR #10926.
- Greptile review: 5/5 with no open comments.
## Risks
- The change touches adapter config assembly.
- A wrong binding shape would change test-time probe input.
- Tests cover the binding types and the create-mode path.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - When an agent runs on a different host (sandbox or SSH), the adapter
transport copies the local git execution workspace to that host and
syncs changes back after the run
> - The transport materializes the remote copy with `git init` plus a
depth-1 or bundle fetch, so the copy has no `origin` remote and its head
reads as a parentless snapshot commit
> - An agent asked to publish its branch (push it, open a pull request)
sees "no remote, root snapshot" and must hand the publish step back to a
human operator, even when the branch base is a commit the upstream
remote already holds
> - This pull request carries the workspace's `origin` URL
(credential-scrubbed) onto the transported copy as metadata
> - The benefit is that branches produced in transported workspaces stay
publishable by any actor with credentials, while the transport itself
still never fetches or pushes
## Linked Issues or Issue Description
No public issue exists. Description follows the enhancement template:
**What existing behavior does this improve?**
The workspace transport in `@paperclipai/adapter-utils` already copies a
git workspace to the execution host and back. This change improves the
fidelity of that copy: the transported repo keeps the workspace's
`origin` remote instead of losing it.
**Subsystem affected**
Adapter utilities — the sandbox transport
(`withShallowGitWorkspaceClone` in
`packages/adapter-utils/src/git-workspace-sync.ts`) and the SSH
transport (`importGitWorkspaceToSsh` in
`packages/adapter-utils/src/ssh.ts`).
**Current behavior**
The transported copy is built with `git init` plus a depth-1 (sandbox)
or bundle (SSH) fetch. It has no remotes. `git remote -v` is empty and
the head commit reads as a root snapshot with no visible ancestry.
Agents and operators inside the execution host cannot fetch real
ancestry or push a branch, even when the branch base is a commit the
upstream remote already holds.
**Proposed behavior**
The transport reads the source workspace's `origin` URL, scrubs
credentials from it, and configures it on the transported copy. The
sandbox path adds the remote to the fresh clone. The SSH path sets or
adds the remote in the remote setup script, which also covers reused
workspace directories. A workspace with no `origin` transports exactly
as before.
**Reason and benefit**
A branch committed in a transported workspace becomes publishable in
place: the shallow boundary commit already exists on the remote, so a
push pack closes without full local ancestry (a new test locks in this
property). Fetching real ancestry also becomes possible for whoever
holds credentials. Without this, agents must describe their change in a
handoff document and a human must reconstruct the branch by hand.
**Breaking changes**
None. The URL copy is best-effort and metadata-only. The transport never
fetches from or pushes to the remote. The no-remote-git contract holds:
sync-back through the local cwd stays the only cross-run persistence
path, and `packages/adapters/AUTHORING.md` gains a paragraph that makes
the carried-remote nuance explicit.
## What Changed
- `packages/adapter-utils/src/git-workspace-sync.ts`: new
`sanitizeGitRemoteUrl` (strips http(s) userinfo, where tokens can be
embedded; scp-like/ssh forms and filesystem paths pass through) and
`readSanitizedOriginRemoteUrl`; `withShallowGitWorkspaceClone`
configures the scrubbed `origin` on the fresh clone, best-effort.
- `packages/adapter-utils/src/ssh.ts`: `importGitWorkspaceToSsh` sets or
adds the scrubbed `origin` in the remote setup script, non-fatal under
`set -e`.
- `packages/adapter-utils/src/git-workspace-sync.test.ts`: four new
integration cases (remote copied, credentials scrubbed, no-origin
unchanged, push from the shallow clone to an origin that holds the base
commit) plus `sanitizeGitRemoteUrl` unit tests.
- `packages/adapters/AUTHORING.md`: documents that a transported copy
may carry a credential-scrubbed `origin` as metadata, and why this does
not weaken the no-remote-git contract.
## Verification
- `npx vitest run packages/adapter-utils/src/git-workspace-sync.test.ts`
— 12/12 pass (4 new integration cases + sanitizer unit tests).
- `npx vitest run
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` — 24/24
pass.
- `npx vitest run packages/adapter-utils/src/ssh-fixture.test.ts` —
16/16 pass, including the `no-remote-git contract` case (a workspace
without `origin` still round-trips with no remote introduced at any
point).
- `node scripts/check-no-git-push.mjs` — passes; this change adds no
push or fetch to adapter/runtime code.
- `pnpm typecheck` in `packages/adapter-utils` — clean.
## Risks
- Low risk. The change is additive metadata on the transported copy
only; failure to record the remote never fails the transport.
- Credential exposure is the real hazard and is handled: http(s)
userinfo is stripped before the URL leaves the host. Non-http forms
(scp-like, `ssh://`) carry no secret in the URL and pass through.
- A reused SSH workspace whose project `origin` changed now gets the
current URL via `set-url` instead of keeping a stale one.

## Thinking Path
> - Paperclip uses spans and traces to show how work moves through
agents and tools
> - sandbox.exec spans need a real parent so the trace tree matches the
work tree
> - Wrong parent links make execution history hard to read and hard to
debug
> - This pull request adds a single task.run root span and re-parents
live work to the nearest active span
> - The change keeps detached work under the closest live span instead
of the HTTP root
> - The benefit is a clear trace tree for sandbox.exec work and better
execution diagnosis
## Linked Issues or Issue Description
**What happened?**
sandbox.exec spans attached to the wrong parent or to no live parent in
some paths.
**Expected behavior**
Each sandbox.exec span should attach to the nearest live span.
**Steps to reproduce**
1. Run work that creates sandbox.exec spans during startup and callback
bridge paths.
2. Inspect the trace tree.
3. Observe an orphaned span or a span with the wrong parent.
**Paperclip version or commit**
`672e9de9c8b004aebc1f08e24b612ab067735ad1`
**Deployment mode**
Local dev.
**Additional context**
The branch adds the task.run root span, parents sandbox.startup to it,
and re-parents detached bridge work to the nearest live span.
## What Changed
- Added a task.run root span for the run tree.
- Re-parented sandbox.startup, agent.turn, and detached bridge work to
the nearest live span.
- Added end-to-end trace-tree assertions for the full parent chain.
- Added negative coverage so sandbox.exec does not parent to the HTTP
root.
## Verification
- Focused Vitest suite passed:
`packages/adapter-utils/src/acpx-engine/execute.test.ts`,
`packages/adapter-utils/src/acpx-engine/startup-timing.test.ts`,
`packages/adapter-utils/src/execution-target-sandbox.test.ts`,
`packages/adapter-utils/src/sandbox-callback-bridge.test.ts`, and
`server/src/__tests__/environment-execution-target.test.ts`.
- Result: 5 files passed, 204 tests passed.
- The submitted branch also reported `adapter-utils` checks, `server`
seam checks, and `tsc` exit 0 in the handoff state.
## Risks
- This change can alter trace tree shape in tools that read parent
spans.
- A missed bridge path could still point to the wrong live span.
- Low risk for runtime behavior, because the change only changes span
parent attribution.
## Model Used
OpenAI GPT-5, tool-use capable.

## Thinking Path
> - Paperclip is the control plane that lets humans govern companies of
AI agents.
> - Issue-thread interactions are the structured handoff point for
confirmations, questions, suggested tasks, and other governed decisions.
> - Those interactions previously assumed that only board users could
resolve them, preventing one agent from explicitly addressing another
agent for a response.
> - Agent resolution needs company-level governance, auditable resolver
identity, safe terminal-state handling, and attention routing so
authorization is enforced server-side rather than inferred from UI
behavior.
> - This pull request adds governed agent resolution, withdrawal and
terminal expiry semantics, explicit agent addressees, lifecycle
reconciliation, and attention-feed filtering.
> - The benefit is that agents can participate in structured decisions
without weakening board control, company isolation, wake behavior, or
audit invariants.
## Linked Issues or Issue Description
### Subsystem affected
Issue-thread interactions across database, shared contracts, server
authorization/services, adapter callbacks, agent skill guidance, API
docs, and UI governance surfaces.
### Problem or motivation
Structured interactions were board-only, had no explicit agent
addressee, and lacked durable withdrawal/terminal-expiry semantics. That
made peer-agent decisions impossible to authorize and audit safely.
### Proposed solution
Persist requested/effective resolver policy and addressee identity,
enforce company governance and eligible agent resolution, reconcile
addressee lifecycle changes, expose withdrawal and terminal expiry, and
route attention to the intended active agent with board fallback.
### Alternatives considered
Implicitly authorizing the issue assignee or mentioned agents was
rejected as ambiguous and difficult to audit. Using comments alone was
rejected because it loses structured outcomes and continuation behavior.
### Roadmap alignment
Supports the ROADMAP direction for lightweight leadership-agent
communication that still resolves into governed decisions and work
objects.
### Additional context
Public GitHub issue/PR search found no duplicate implementation; open PR
search for interaction resolver governance and agent addressees only
returned this PR.
## What Changed
- Add company-scoped interaction resolver governance contracts and
persistence.
- Add requested/effective resolver policy, resolver identity,
withdrawal, and terminal-expiry behavior.
- Add explicit `addresseeAgentId` validation, authorization,
persistence, lifecycle reconciliation, API documentation, and skill
guidance.
- Route pending addressed interactions to the intended invokable agent
and fall back to board attention when that agent becomes ineligible or
is deleted.
- Preserve sandbox callback identity fields required by governed
resolution paths.
- Add migrations `0193` and `0194` plus route, service, attention,
adapter, CLI, and UI coverage.
- Add governance state and company settings UI, including responsive
mobile behavior and distinct withdrawn/expired audit presentation.
## Verification
- `pnpm check:token-gates` — passed.
- `pnpm -r typecheck` — passed, including migration numbering and safety
checks.
- `pnpm test:run` — feature/server and UI workspace suites passed; one
unrelated CLI AWS doctor test observed injected static AWS credentials
and warned instead of passing.
- `env -u AWS_ACCESS_KEY_ID -u AWS_SECRET_ACCESS_KEY pnpm exec vitest
run cli/src/__tests__/secrets.test.ts --project paperclipai` — 8 tests
passed, confirming the failure was environment-sensitive.
- `pnpm build` — passed.
- Latest rebased head `e24cece6be9f1877bdbac7691bcb44fd583c0161`
completed all GitHub CI jobs successfully.
## Risks
- Migrations add interaction and company-governance fields; numbering is
conflict-free on current `master`, additive statements are idempotent,
and migration safety checks pass.
- Agent authorization behavior expands beyond board-only resolution, but
defaults remain board-only and coverage exercises company boundaries,
resolver eligibility, lifecycle invalidation, wake behavior, withdrawal,
expiry, and attention fallback.
- Attention routing depends on current agent invokability;
reconciliation and read-time filtering prevent stale addressees from
retaining visibility or resolution authority.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work

metadata
## Linked Issues or Issue Description
**Bug**
**What happened?**
Long-lived bridge continuations kept a stale startup step store during
the queue-directory setup path.
**Expected behavior**
Runtime exec spans should start with no active startup step.
**Steps to reproduce**
1. Start a bridge lane.
2. Let the startup step end.
3. Run later runtime exec work on the same lane.
**Paperclip version or commit**
223068e2ff
**Deployment mode**
Self-hosted server
## What Changed
- Added `runWithoutActiveStep` in
`packages/adapter-utils/src/acpx-engine/startup-timing.ts`.
- Wrapped the long-lived poll timer, socket handlers, and
callback-bridge worker loop in both bridge lanes.
- Added unit tests for store leak and reset behavior.
- Added continuation tests for both bridge lanes and the `criticalPath`
flag.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit`
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/startup-timing.test.ts`
- `pnpm exec vitest run
server/src/__tests__/environment-execution-target.test.ts`
## Risks
- Low risk.
- The change alters async context handling in bridge continuations.
- If a caller depends on inherited step state, this change removes it.
- The tests cover the intended bridge lanes.
## Model Used
OpenAI Codex, GPT-5, tool use enabled.

## Thinking Path
> - Paperclip tracks agent work for the team.
> - The startup timing path already emits detailed spans.
> - The run log repeats the same detailed timing.
> - That makes the event larger than it needs to be.
> - This pull request removes the redundant per-step timing fields from
the run-log payload.
> - The benefit is a smaller log with the same detail still available in
traces.
## Linked Issues or Issue Description
No public GitHub issue or open pull request matches this change. I
described the enhancement below.
**What existing behavior does this improve?**
`run.startup.step` event output.
**Subsystem affected**
Cross-cutting (multiple of the above)
**Current behavior**
`run.startup.step` writes `roundTrips`, `providerExecMs`,
`providerGetMs`, `createRuntimeMs`, and `ensureSessionMs`. The same
detail already exists in the spans.
**Proposed behavior**
`run.startup.step` keeps only `step`, `durationMs`, and `outcome`. The
heartbeat lifecycle timestamps stay unchanged.
**Reason and benefit**
This change removes redundant data from the run log. It keeps the useful
detail in trace spans. It also makes the payload smaller and easier to
read. The revert path stays clear because the removed data has one
producer chain.
**Breaking changes**
Yes. Consumers that read the removed fields must switch to span data or
the remaining event fields. The heartbeat lifecycle timestamps do not
change.
**Additional context**
I searched GitHub for related open PRs and issues. I found no match.
## What Changed
- Removed the redundant per-step timing fields from the run-log payload.
- Removed the now-dead producer chain that fed those fields.
- Kept the span-level timing data and the heartbeat lifecycle
timestamps.
## Verification
- `adapter-utils` typecheck clean
- `server` typecheck clean
- `startup-timing` suite: 30 passed
- `adapter-utils` `execute` suite: 99 passed
- `server` `environment-execution-target` suite: 21 passed
## Risks
- Consumers that still read the removed fields will need a code change.
- This is a one-way-door data removal for the run log.
## Model Used
OpenAI Codex, GPT-5, tool use enabled.

## Thinking Path
> - Paperclip uses pull requests to ship control-plane changes with
review and audit.
> - This change extends sandbox provider telemetry.
> - The first PR added startup and exec spans.
> - This PR adds provider spans for cache hits, plugin tracer flow, and
Daytona file sync steps.
> - The host must keep the trust boundary and reject unsafe span data.
> - The result is fuller OTel coverage with bounded labels and safe
parentage.
## Linked Issues or Issue Description
**Problem or motivation**
Sandbox provider telemetry lacks an explicit cache-hit signal, plugin
span context, and file-sync pack and transfer spans.
The current proxy for a cache hit is fragile.
The plugin SDK also needs a safe tracer surface and a per-call parent
context.
**Proposed solution**
Add an explicit `cacheHit` flag from the Daytona sandbox handle lookup.
Expose `ctx.tracer` on the plugin context and pass a `traceparent`
string with each call.
Record provider spans on the host with allowlist clamping and capability
checks.
Wrap Daytona file sync pack and transfer steps in spans.
**Alternatives considered**
Keep the old `providerGetMs == 0` proxy.
Reject that path because the cache-hit decision belongs at the handle
lookup, not in a timing proxy.
The host stays the trust boundary for worker span data.
It clamps labels, rejects bad parent data, and gates the worker-to-host
span RPC by capability.
A security review completed before this PR opened.
## What Changed
- Added an explicit `cacheHit` flag from the Daytona sandbox handle
lookup.
- Added `ctx.tracer` on the plugin context and a `traceparent` field in
the per-call context.
- Added host-side span recording with attribute clamping and capability
checks.
- Wrapped Daytona file sync pack and transfer steps in spans.
- Added tests for the host trust boundary, the plugin tracer no-op path,
and the Daytona span paths.
## Verification
- `pnpm --filter @paperclipai/plugin-daytona exec vitest run`
- `pnpm --filter @paperclipai/plugin-sdk exec vitest run`
- `pnpm --filter @paperclipai/server exec vitest run
plugin-host-services environment-execution-target instrumentation
plugin-worker-manager`
- `tsc --noEmit` for server, plugin-sdk, and adapter-utils
## Risks
- Span data now crosses the worker boundary, so the host allowlist and
capability gate must stay strict.
- The `traceparent` path must stay valid and host-owned.
- Daytona file sync spans must not add new round trips.
## Model Used
OpenAI Codex, GPT-5, tool use.

## Thinking Path
> - Paperclip coordinates AI agent work and records execution data.
> - The sandbox startup path and the host-to-sandbox execution path need
clearer OpenTelemetry spans.
> - The trace data now shows wait time, critical path data, and bounded
labels.

leakage.
## Linked Issues or Issue Description
- No public GitHub issue exists for this branch.
- Related PR: #10536
- This PR extends the sandbox OpenTelemetry work with exec spans, root
timing, and bounded labels.
## What Changed
- Added a closed span-attribute contract for sandbox startup data.
- Added a bounded label helper for command and region values.
- Threaded the active step context into the execution path.
- Added a `sandbox.exec` span with true timestamps and bounded
attributes.
- Added skipped-step and root-span timing data with low-cardinality
context.
- Moved handshake sub-times and bridge batch data onto spans.
## Verification
- `pnpm --filter @paperclipai/adapter-utils run typecheck`
- `pnpm --filter @paperclipai/server run typecheck`
- `pnpm --filter @paperclipai/adapter-utils exec vitest run`
- `pnpm --filter @paperclipai/server exec vitest run
environment-execution-target`
- `git log --oneline
origin/master..origin/feat/sandbox-startup-otel-spans`
- `git diff origin/master...origin/feat/sandbox-startup-otel-spans
--stat`
## Risks
- Span attribute rules could still miss a future field if new code skips
the shared helper.
- Low-cardinality labels may hide some detail, but that is the intended
tradeoff.
- Tracing stays fail-open, so a missing tracer still hides data rather
than stopping work.
## Model Used
- OpenAI Codex, GPT-5, tool use enabled. The runtime did not expose the
context window size.

The current head still has one failing required check: `e2e`. The PR

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The heartbeat service is the control plane that runs agents through
adapters and records each run's usage and cost in the finance/cost
ledger
> - Adapters report a provider cost (`costUsd`), but there is no way to
represent the provider-billed cost *after* prompt-cache discounts, so
cache-heavy runs are priced wrong and some paid runs end up exported
with a zero/null cost
> - A benchmark comparing Paperclip-orchestrated runs against direct
harness invocation of the same tasks measured 1.5–3.1× higher apparent
USD per pair, largely because cache-discounted billing was not
represented in the exported cost data
> - This pull request adds an optional `cacheAdjustedCostUsd` field to
`AdapterExecutionResult` and a `resolveCacheAdjustedCostUsd` helper in
the heartbeat service that prefers the explicit cache-adjusted figure
and falls back to the reported `costUsd`, persisting it into the run's
usage/ledger JSON
> - The benefit is that paid runs are no longer exported as zero/null
cost and cache-heavy runs can be priced correctly, so operators
comparing orchestrated vs. direct costs see real numbers
## Linked Issues or Issue Description
No single existing public issue covers this exactly; closely related
cost-reporting issues:
- Refs #8947 — hermes adapter never reports usage/cost to Paperclip, so
budget limits never trigger
- Refs #6716 — hermes_local cost/usage capture returns zero
- Refs #3320 — expose per-run token counts in activity log and dashboard
**Problem (feature-request form):** Adapters can only report a single
`costUsd`. Providers with prompt caching bill less than the nominal
token cost, and the heartbeat cost accounting has no field for the
cache-adjusted billed amount. As a result, cache-heavy paid runs are
either priced at the undiscounted figure or, when the adapter withholds
the ambiguous number, exported as zero/null. **Proposed solution:** an
explicit optional `cacheAdjustedCostUsd` on the adapter execution
result, resolved server-side with a safe fallback to `costUsd`.
**Alternatives considered:** recomputing cache discounts server-side
from token counts (rejected: provider pricing tables drift and cache
billing rules are provider-specific; the adapter is the source of
truth).
## What Changed
- `packages/adapter-utils/src/types.ts`: added optional
`cacheAdjustedCostUsd?: number | null` to `AdapterExecutionResult`, with
a doc comment on adapter expectations
- `server/src/services/heartbeat.ts`: added exported
`resolveCacheAdjustedCostUsd()` (explicit cache-adjusted value wins when
a finite non-negative number; otherwise falls back to a finite
non-negative `costUsd`; otherwise `null`), and consistently uses the
resolved billed value for ledger cents, cost status, and run usage JSON
- `server/src/__tests__/heartbeat-cost-accounting.test.ts`: added unit
coverage for explicit precedence, fallback, invalid values,
adjusted-only pricing, and discounted ledger billing
## Verification
- `pnpm exec vitest run
server/src/__tests__/heartbeat-cost-accounting.test.ts` — 1 file, 7
tests passed
- `pnpm --filter @paperclipai/adapter-utils typecheck` — passed
- `pnpm --filter @paperclipai/server typecheck` — passed
- GitHub Actions on head `dc9c3830bf694b9afb3b27c5c8c36bff38e7fdcb` —
all 26 checks clean/skipped; one unrelated E2E checkout-contention flake
passed on its single failed-job rerun
- Greptile review on the same head — 5/5 with zero unresolved threads
## Risks
- Low risk: the field is optional and additive; when absent, behavior
falls back to the existing `costUsd` path
- Ledger/usage JSON gains a new optional `cacheAdjustedCostUsd` key —
consumers that strictly validate keys would need to tolerate it (usage
JSON is already open-shaped)
- No migrations, no API-breaking changes

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Operators spend most of their time on the issue detail page. They
talk to the assigned agent there through comments.
> - The current page reads as a ticket form. The thread sits below
properties, the composer sits mid-page, and live agent activity renders
as dense transcript logs.
> - Talking to an agent is a conversation. A chat-first layout matches
that mental model better than a ticket form.
> - A layout change this large must not disrupt current users. It needs
a safe opt-in path and full parity with the existing thread features.
> - This pull request adds a chat-style task view behind a new
"Chat-Style Tasks" experiment toggle. The flag is off by default and the
existing page is unchanged when it is off.
> - The benefit is a focused, readable conversation with the agent: live
tool activity folds into compact summaries, the composer stays at the
bottom, and properties, plan, and artifacts move into header tabs.
## Linked Issues or Issue Description
Refs #49 (chat with agents is a much-wanted feature).
Related PRs found in the dedup search:
- #4489 — an earlier, closed attempt to promote the conversation to the
primary surface on issue detail. This PR is a fresh, flag-gated take on
the same goal.
- #8837 — an open PR that proposes a two-column task layout. It
restructures the same page but keeps the ticket paradigm; this PR is
orthogonal because it is opt-in and chat-first.
**Subsystem affected**
UI (issue detail page).
**Problem or motivation**
The issue detail page presents agent conversations as a ticket:
properties first, thread below, composer in the middle of the page, and
raw transcript noise during live runs. Users who mainly converse with
their agents must scroll past chrome to follow the conversation, and
live activity is hard to read.
**Proposed solution**
An opt-in chat-style view of the issue detail page, gated by a new
"Chat-Style Tasks" experiment toggle in Settings → Experimental. With
the flag on, the thread fills the center pane, the composer docks to the
bottom of the viewport, Properties / Plan / Artifacts become header
tabs, live turns show a status pill with the current tool action and
elapsed time, and settled turns collapse to a "Worked · N tools" summary
that expands into per-tool rows. With the flag off, nothing changes.
**Alternatives considered**
Restyling the existing layout in place (rejected: too disruptive without
an opt-out), and a separate chat page beside the issue page (rejected:
splits the task's single source of truth). A per-request lab page
(`/task-chat-lab`, dev-only) was kept for design iteration instead.
**Roadmap alignment**
ROADMAP.md "CEO Chat" wants lighter conversations that still resolve to
real work objects. This PR keeps the core task-and-comments model — it
only changes presentation, opt-in — so it does not duplicate that
planned work.
## What Changed
- New `enableTaskChatRedesign` instance setting, exposed as a
"Chat-Style Tasks" experiment card in Settings → Experimental (shared
feature catalog, validators, server instance-settings service, and UI
settings page).
- New `ui/src/components/task-chat/` component family: chat thread with
turn grouping, agent reply bubbles, live status pill, collapsible turn
summaries with per-tool rows, plan tab with a sticky CTA action bar,
inline interaction cards, per-request mode chips, and a bottom-docked
composer.
- A shared tool taxonomy (`tool-taxonomy.ts`) maps tool names to verbs
and icons; the status pill, tool rows, and the classic transcript view
all use it.
- A transcript adapter converts stored run logs into chat turns; it
dedupes tool-call updates by `toolUseId` so tool counts match the
expanded rows, and it keeps a tool row's first real name when later
generic updates arrive.
- Composer: posts on Cmd/Ctrl+Enter, supports image paste with
object-URL thumbnail previews (revoked on clear/unmount), and uploads
through the issue attachments route.
- `IssueDetail.tsx`: with the flag on, pane tabs move to the header bar,
the header is not sticky, and the chat fills the center; with the flag
off, the previous layout renders unchanged.
- Motion tokens for the new animations live in `ui/src/index.css` with a
`motion-tokens.ts` catalog and a test that keeps the two in sync (the
catalog now also covers the shared enter/exit/swap tokens that the
decision/quicklook block declares).
- A dev-only `/task-chat-lab` page with fixtures and a tweak panel for
motion tuning.
## Verification
- `pnpm typecheck` — clean across the workspace.
- `pnpm check:token-gates` — 3/3 CLEAN.
- `cd ui && pnpm vitest run` — 3,344 of 3,345 tests pass locally. The
one failure is `IssueProperties.test.tsx` monitor-row time formatting,
which is timezone-sensitive: it also fails on unmodified `origin/master`
in a non-UTC timezone and passes with `TZ=UTC`. It is not related to
this change.
- `cd server && pnpm vitest run
src/__tests__/instance-settings-service.test.ts` — 21/21 pass (covers
the new setting).
- Manual: start the dev server, open Settings → Experimental, enable
"Chat-Style Tasks", and open any issue. The thread fills the page, the
composer docks to the bottom, and Properties / Plan / Artifacts appear
as header tabs. Assign an agent and comment to watch a live run: the
status pill shows the current tool action with elapsed time, and the
finished turn folds into a "Worked · N tools" summary. Disable the
toggle and confirm the classic page is unchanged.
- Visual snapshot baselines are intentionally not updated: per
`doc/design/DECISION-SHEET.md`, "Per-change snapshot verification
demoted to dormant (Jul 13 2026)".
## Risks
- The flag-off path goes through the same `IssueDetail.tsx` file, so a
regression there would affect current users. Mitigation: the classic
markup renders through the same components as before behind explicit
flag conditionals, and the full UI suite passes.
- The transcript adapter interprets stored run-log formats, including
legacy entries without `toolUseId`. Malformed logs degrade to generic
tool rows rather than crashing.
- The new view changes no server behavior other than one additive
instance setting; it is additive and default-off. Overall risk with the
flag off is low.

- Claude (Anthropic), model id `claude-fable-5` (Claude Fable 5),
extended thinking enabled, agentic tool use (file editing, shell, test
execution) via Claude Code / Claude Agent SDK.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - An agent that runs in a sandbox has its workspace copied back to the
host when the run ends, so its work persists — the copy-back ships a git
bundle of the sandbox's commits
> - The bundle is created as a thin delta, `git bundle create HEAD --not
<baseSha>`, which records `baseSha` (the host workspace HEAD captured at
export) as a prerequisite the host must already hold
> - That assumption breaks when the sandbox HEAD has diverged from
`baseSha`, or when a shared host workspace no longer holds `baseSha` at
import time — then `git fetch` on the host hard-fails and the entire run
is lost even though the agent finished its work
> - This pull request bundles against the merge-base of `baseSha` and
the sandbox HEAD (with a full-bundle fallback), which the host can
satisfy in those cases
> - The benefit is that copy-back no longer discards a completed run's
work over a base the host can't reconcile
## Linked Issues or Issue Description
**What happened?**
A sandbox agent run completed its work, then failed during workspace
finalize:
```
git -C <host workspace> fetch --force <git-delta.bundle> refs/…/export:refs/…/imported
error: Could not read <baseSha>
fatal: revision walk setup failed
error: git-delta.bundle did not send all necessary objects
```
The run is reported as `adapter_failed` even though the agent produced
output. The copy-back bundle names the host workspace's recorded HEAD
(`baseSha`) as a prerequisite, but the host cannot satisfy it.
**Steps to reproduce**
Two independent triggers, both reproduced in tests:
1. The sandbox's HEAD has diverged from `baseSha` — e.g. the sandbox
carries a local-only branch that forked from an older commit than the
host's current HEAD.
2. The shared host workspace no longer holds `baseSha` at import time
(it was reset / re-realized between export and import).
In either case `git fetch` of the thin bundle fails with a missing
prerequisite.
**Expected behavior**
Copy-back imports the sandbox's work as long as the host holds any
common ancestor, instead of hard-failing and discarding the run.
**Paperclip version**
Current `master`.
**Deployment mode**
Any deployment running agents in sandbox environments with workspace
sync (notably shared-workspace clones and custom images that carry a
local-ahead branch).
## What Changed
- `buildRemoteGitDeltaBundleScript` now computes `bundle_base = git
merge-base <baseSha> HEAD` and bundles `HEAD --not <bundle_base>`. The
merge-base is an ancestor of `baseSha`, so any host that holds `baseSha`
(or an ancestor of it — e.g. after a reset) can satisfy the
prerequisite, and the bundle stays a delta rather than a full-history
transfer.
- When `baseSha` is absent from the sandbox, or no merge-base exists, it
falls back to a full, self-contained bundle (no prerequisites) so the
import can always complete.
- The existing empty-bundle no-op (no new commits) and the ordinary
fast-forward path are unchanged; the `cat-file` base check no longer
aborts the script under `set -e`.
## Verification
- `pnpm vitest run packages/adapter-utils/src/git-workspace-sync.test.ts
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` — new cases:
a diverged sandbox HEAD imports when the host holds only the merge-base
(not `baseSha`), and the full-bundle fallback imports into a host that
shares no history; existing thin-delta and empty-bundle cases still
pass.
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit`.
- Standalone shell repro confirmed the old thin bundle fails with
"Repository lacks these prerequisite commits" in both trigger cases, and
the merge-base bundle imports successfully.
## Risks
- Low. For the common case (sandbox HEAD descends from `baseSha`) the
merge-base is `baseSha`, so the bundle is byte-for-byte the same delta
as before. The change only alters behavior when the old code would have
hard-failed.
- This makes the copy-back import succeed on a diverged base; the
subsequent reconciliation of divergent histories
(`integrateImportedGitHead`) is unchanged and still owns how the
imported head is merged into the host branch. Where a workspace's
history has genuinely diverged (e.g. a stale custom image carrying a
local-only branch), a clean re-clone/re-capture is still the right
operational fix — this change prevents work loss, it does not reconcile
intentional divergence.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local agent wakes include a default execution contract
> - That contract tells agents how issue-thread continuation policies
behave
> - The current text says `wake_assignee` resumes a confirmation only
after acceptance
> - The server actually wakes for every non-expired resolution and
reserves acceptance-only behavior for `wake_assignee_on_accept`
> - This pull request makes the default prompt match the server contract
and strengthens the recovery follow-up regression case
> - The benefit is that agents choose the correct continuation policy
and recovery tests cover normalized agent name keys
## Linked Issues or Issue Description
Related work: Refs #5473, Refs #5060, and Refs #10562.
**What happened?**
The default local-agent prompt described `wake_assignee` as
acceptance-only for `request_confirmation`. This conflicts with the
server. The server wakes on every non-expired resolution. A recovery
follow-up test also used an already-normalized execution agent name key,
so it did not exercise the normalization seam.
**Expected behavior**
The prompt must state that `wake_assignee` resumes after acceptance or
rejection. It must direct acceptance-only flows to
`wake_assignee_on_accept`. The recovery regression must use a
display-style agent name key and prove that the follow-up path still
works after normalization.
**Steps to reproduce**
1. Read the default local-agent prompt in
`packages/adapter-utils/src/server-utils.ts`.
2. Compare its confirmation continuation text with
`queueResolvedInteractionContinuationWakeup` in
`server/src/routes/issues.ts`.
3. Observe that the prompt gives acceptance-only semantics to
`wake_assignee`.
4. Inspect the recovery hand-back test and observe that its execution
name key is already normalized.
**Paperclip version or commit**
`7301fae942`
**Deployment mode**
Local dev. The prompt and test behavior are not deployment-specific.
## What Changed
- Corrected the default agent prompt for `wake_assignee` and
`wake_assignee_on_accept`.
- Added focused prompt assertions for both the required and obsolete
text.
- Changed the recovery follow-up fixture to use a display-style agent
name key.
## Verification
- `pnpm exec vitest run packages/adapter-utils/src/server-utils.test.ts
-t 'keeps the default local-agent prompt action-oriented'` passed: 1
test.
- `pnpm exec vitest run
server/src/__tests__/heartbeat-comment-wake-batching.test.ts -t 'defers
recovery hand-back wakes until the resolving run exits'` passed: 1 test.
- `pnpm --filter @paperclipai/adapter-utils typecheck` passed.
- `pnpm --filter @paperclipai/server typecheck` passed.
- `git diff --check origin/master...HEAD` passed.
## Risks
- Low risk. The production change updates prompt text only.
- Agents that followed the old text may now choose
`wake_assignee_on_accept` for acceptance-only flows.
- The server test change only broadens an existing regression fixture.

## Thinking Path
> - Paperclip is the open source control plane people use to manage AI
agents for work.
> - Local agent heartbeats need durable process identity so the server
can supervise them.
> - The ACPX runtime owns the child process used by `codex_local`
sessions.
> - ACPX did not expose the child PID and start time to the Paperclip
adapter.
> - Warm ACPX runtimes can also serve a later heartbeat without a new
spawn event.
> - A hot restart could therefore classify a live Codex run as lost
because its heartbeat row had no process identity.
> - This pull request forwards ACPX spawn identity, reuses it for
compatible warm heartbeats, and fails closed when identity cannot be
persisted.
> - The benefit is reliable hot-restart adoption for eligible local
Codex runs.
## Linked Issues or Issue Description
No matching public GitHub issue was found.
**What happened?**
A `codex_local` heartbeat could run through ACPX without a persisted
`processPid` or `processStartedAt`. A Paperclip hot restart then had no
durable identity for the live ACP child. Recovery could classify the run
as `process_lost` even while the child was still alive.
**Expected behavior**
ACPX reports the real child PID and start time before the first prompt.
A compatible warm runtime reports the same known identity to each later
heartbeat that reuses the child. ACPX stops the child if the identity is
invalid or persistence fails. Hot-restart recovery can then adopt the
live run.
**Steps to reproduce**
1. Start a `codex_local` heartbeat through the ACPX execution lane.
2. Keep the run active during a Paperclip hot restart.
3. Inspect the heartbeat row before this change.
4. Observe that the process identity can be null and recovery cannot
adopt the live child.
**Reproduced on**
- Paperclip `master` before this change.
- Linux source deployment.
- `codex_local` with ACPX `0.12.0`.
## What Changed
- Add an awaited `onAgentSpawn` lifecycle hook to the patched ACPX
runtime.
- Forward the ACP child PID and start time through the adapter `onSpawn`
callback.
- Keep a mutable callback sink for cached runtimes so a later respawn
updates the current heartbeat.
- Reuse the last known process identity when a compatible warm heartbeat
reuses the existing child.
- Kill the ACP child and fail session startup when the PID is invalid or
identity persistence rejects.
- Add ACPX and heartbeat recovery tests for callback ordering, warm
reuse, failure cleanup, durable row identity, and hot-restart adoption.
- Document the one-time drain required when an installed pre-fix run
already lacks process metadata.
## Verification
-
`PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/test-home-execute-escalated"
pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` — 89 passed.
-
`PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/test-home-recovery-escalated"
pnpm exec vitest run
server/src/__tests__/heartbeat-process-recovery.test.ts` — 92 passed.
-
`PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/test-home-remote-smoke-escalated"
pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/remote-spawn-smoke.test.ts` — 3
passed.
-
`PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/test-home-ci-repro-escalated"
pnpm exec vitest run
server/src/__tests__/heartbeat-dependency-scheduling.test.ts` — 6
passed.
- `pnpm --filter @paperclipai/adapter-utils typecheck` — passed.
- Reverse and forward dry-run application of `patches/acpx@0.12.0.patch`
— passed.
- `git diff --check` — passed.
- `git diff --exit-code origin/master...HEAD -- pnpm-lock.yaml` —
passed.
- `git diff --exit-code origin/master...HEAD -- .github/workflows` —
passed.
## Risks
- Runtime risk is low to moderate. ACPX now awaits process-identity
persistence during child startup.
- ACPX kills the child when persistence fails. This prevents an
unsupervised process, but it makes that heartbeat fail visibly.
- A compatible warm heartbeat reuses the identity of the existing ACP
child. Regression tests verify that identity is persisted before the
next prompt.
- The change updates the vendored ACPX patch. Package installation must
apply that patch.
- There are no schema, migration, public API, UI, workflow, or lockfile
changes.

## Model Used
- OpenAI Codex used GPT-5.3-Codex for the earlier implementation.
- OpenAI Codex used GPT-5 for the lifecycle-hook revision and the
current fail-closed review fix. The runtime did not expose a more
specific snapshot ID or context-window size. Both runs used reasoning,
repository tools, and code execution.

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This change touches server orchestration, sandbox
transport, and observability.
**Problem or motivation**
A run can @-mention another project. Local targets stage each referenced
project and give the agent a path. Remote confined sandboxes dropped the
full referenced set, so the agent could not read those project files or
paths.
**Proposed solution**
Enable referenced-project sync for the confined sandbox transport behind
`PAPERCLIP_MULTI_PROJECT_WORKSPACE_SYNC_REMOTE`, which defaults on. Keep
the SSH transport out of scope and keep it dropping referenced projects.
Repoint each referenced workspace hint at its staged
`project-<projectId>` sandbox directory. Publish
`PAPERCLIP_WORKSPACES_JSON` on the confined sandbox lane. Count each
per-project remote staging failure as a `staging` failure in the
requested-vs-synced metrics.
**Alternatives considered**
Keep the remote path drop-only. That keeps the gap open. Move the change
into SSH too. That expands scope beyond the target transport and adds
risk.
**Roadmap alignment**
No matching item in `ROADMAP.md` showed up in this review.
**Additional context**
The change lands in three commits. The first commit opens the gate for
the confined sandbox transport. The second commit repoints the workspace
hints and publishes the workspace map. The third commit records
per-project staging failure data.
## What Changed
- Opened remote referenced-project sync for the confined sandbox
transport behind `PAPERCLIP_MULTI_PROJECT_WORKSPACE_SYNC_REMOTE`.
- Repointed referenced workspace hints to the staged
`project-<projectId>` sandbox directories and published
`PAPERCLIP_WORKSPACES_JSON`.
- Counted per-project remote staging failures as first-class `staging`
failures in the requested-vs-synced observability.
## Verification
- The pushed ref
`refs/heads/feat/sync-referenced-projects-remote-sandbox` resolves to
the authorized submit SHA.
- `git log --oneline
origin/master..origin/feat/sync-referenced-projects-remote-sandbox`
shows exactly the three expected commits.
- The handoff reports server typecheck clean, adapter-utils typecheck
clean, and the listed unit tests passing.
- The handoff also reports no open review comments and no Greptile score
yet.
## Risks
- The change touches authorization and sandbox path handling, so
regressions could block remote runs or expose the wrong project context.
- The new flag defaults on, so any bug in the remote path affects normal
remote use.
- SSH stays out of scope, so the two transport paths must remain
distinct.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The recovery subsystem restores work after an agent run stops or
loses state
> - Recovery notices currently use the same visual weight as normal work
comments
> - Recovery agents can also post long narratives that obscure the
useful hand-off
> - The server must identify recovery output because agents cannot set
presentation controls
> - This pull request adds compact recovery notices, structured action
references, and brief recovery prompts
> - The benefit is a quieter issue thread that still keeps recovery
state inspectable
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting: `server/`, `packages/shared`, and
`packages/adapter-utils`.
**Problem or motivation**
Recovery notices and recovery-run comments can dominate an issue thread.
Operators must scan routine recovery narration before they find the work
hand-off.
**Proposed solution**
Give routine recovery output a compact system-notice presentation.
Derive the presentation on the server so agents cannot hide arbitrary
comments. Keep the successful missing-state summary fully visible
because that comment is the recovery deliverable.
**Alternatives considered**
The UI could detect recovery text. That approach is fragile and does not
provide structured action references. Agents could also set presentation
directly, but that would weaken the current board-only security
boundary.
**Roadmap alignment**
This change refines the completed “Self-healing runs & automatic
recovery” and “Enforced Outcomes” roadmap areas. It does not add a
competing roadmap capability.
**Additional context**
The scope covers shared comment validation, server recovery notices,
agent-comment derivation, and recovery prompt text. No database
migration is needed because presentation data already uses JSON.
## What Changed
- Add the `compact` issue-comment presentation density to shared
constants, types, and validation.
- Give recovery escalation, waiting, and in-place notices compact titles
and structured recovery-action metadata.
- Use recovery-action metadata for notice deduplication, with the legacy
text marker as a compatibility fallback.
- Derive compact presentation for comments from recovery-scoped runs
while preserving the board-only presentation boundary.
- Keep successful missing-state recovery summaries fully visible.
- Ask recovery participants to record outcomes in `resolutionNote` and
keep source-issue comments brief.
- Add shared, route, service, and prompt tests for the new behavior and
exceptions.
## Verification
- `pnpm -r typecheck`
- Focused Vitest coverage: 320 tests passed across shared validators,
adapter prompts, issue comments, recovery actions, and heartbeat
recovery.
- Full server phase: 292 files passed, 3,094 tests passed, and 2 tests
skipped.
- Full UI phase: 386 files passed and 3,182 tests passed.
- `pnpm build`
- Known master baseline: `cli/src/__tests__/secrets.test.ts` expects
`pass`, but the current implementation returns `warn` when strict secret
mode is disabled for Postgres. This branch does not change CLI secrets
code.
## Risks
- Low migration risk. The presentation column is JSON and needs no
database migration.
- Recovery-run detection depends on the persisted run context snapshot.
- Structured metadata becomes the primary deduplication key. The
existing body marker remains as a fallback for older comments.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex with `gpt-5.6-sol`. The runtime did not expose the
context-window size. The model used agentic reasoning, repository tools,
code execution, and test execution.

## Thinking Path
> - Paperclip moves agent work through sandboxed execution and
control-plane services.
> - The sandbox start path now has a no-op span seam.
> - This change turns that seam on when OTLP export is configured.
> - It keeps the default path unchanged when export is off.
> - The result is structured startup traces with low-cardinality
attributes and explicit parent links.
> - The benefit is better observability without changing normal
behavior.
## Linked Issues or Issue Description
No public GitHub issue exists for this change.
### Problem
The sandbox start path has a tracer seam, but it stays a no-op unless
the OTLP export path is active.
### Proposed solution
Enable the server tracer on sandbox bring-up, open a root span, parent
each startup boundary to that root, and keep the export path opt-in
behind `OTEL_EXPORTER_OTLP_ENDPOINT`.
### Alternatives considered
- Keep the start path as a no-op. I rejected that path because it leaves
sandbox start opaque when OTLP export is already configured.
- Add broad attributes for commands and paths. I rejected that path
because the span allowlist must stay low-cardinality.
### Roadmap alignment
This follows the current OTel sandbox-start work and keeps the default
path unchanged.
## What Changed
- Add a root sandbox startup span and child spans for each named startup
boundary.
- Keep concurrent bridge spans parented to the root span.
- Inject the server tracer through the adapter deps without
OpenTelemetry imports in the engine.
- Attach host-received provider duration attributes only when the values
are finite.
- Keep span attributes inside the allowlist and keep command, path, id,
and error text out of span data.
## Verification
- The pushed branch already passed `pnpm --filter
@paperclipai/adapter-utils exec tsc --noEmit`.
- The pushed branch already passed `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/`.
- The pushed branch already passed `pnpm --filter @paperclipai/server
exec vitest run src/__tests__/environment-execution-target.test.ts
src/__tests__/instrumentation.test.ts`.
- The pushed branch already passed `pnpm --filter @paperclipai/server
exec tsc --noEmit`.
## Risks
- OTel export changes trace volume when the endpoint is set.
- The allowlist limits trace detail, so new fields need care.
- The change stays no-op when OTLP export is off.
## Model Used
- OpenAI GPT-5, tool use enabled.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is the control plane for AI agent companies
> - Sandbox providers move files between the host and the sandbox
> - The runtime needs advisory data for which sync paths are writable
> - The host already knows that intent when it prepares the sync map
> - Daytona can record that intent for later use
> - This pull request adds the advisory access field and collects
writable paths
> - The benefit is that later runtime work can use the data without
changing current flow
## Linked Issues or Issue Description
No public GitHub issue exists for this change. The description below
follows the feature-request template fields.
### Problem or motivation
An agent runs inside an ephemeral sandbox. Some sandbox paths keep agent
changes; other paths do not. Today the runtime has no declared signal
for which sync destinations the agent may change and keep. A later
feedback wrapper needs this signal to give the agent real-time feedback
when a write lands on a non-persistent path.
### Proposed solution
Add an optional advisory `access: "rw" | "ro"` field to the sync
file-mapping types. The host sets `rw` for the workspace, git-history,
and asset destinations, and `ro` for referenced-project trees. An absent
value defaults to `ro`. The Daytona provider collects the `rw` target
directories into a per-lease writable set for later use. This change
adds the metadata and the collection only. No execution path reads the
writable set yet, so runtime behavior does not change.
### Alternatives considered
Derive a static writable set in provider code. This alternative is
weaker: the layer that authors each sync destination already knows the
intent, so a per-operation declaration is more accurate and does not
hard-code a path list.
### Roadmap alignment
This is the first step toward an advisory sandbox feedback wrapper. The
wrapper is best-effort and adds no security. The ephemeral sandbox stays
the only boundary.
### Additional context
The field is advisory metadata. It does not change the file transfer and
adds no security.
## What Changed
- Added an optional `access` field to the sync file mapping types.
- Set the workspace, git history, and asset destinations to writable.
- Set referenced project destinations to read only.
- Added a writable set store in the Daytona provider.
- Recorded the parent directory of each writable sync mapping during
sync in.
## Verification
- The handoff reports these checks before push.
- `pnpm --filter @paperclipai/adapter-utils exec vitest run
sandbox-managed-runtime.test.ts`
- `pnpm --filter @paperclipai/plugin-sdk exec tsc --noEmit`
- `vitest run src/plugin.test.ts` in the Daytona package
- `tsc --noEmit` in the Daytona package
## Risks
- Low risk.
- The new field is advisory.
- The writable set store is best effort and in memory.
- A cold store falls back to the workspace baseline.
## Model Used
OpenAI Codex, GPT-5, tool use, code execution.

## Thinking Path
> - Paperclip helps people run and govern AI agent work
> - Sandbox startup needs a safe place to add telemetry spans without
forcing OpenTelemetry on every run
> - This change adds a no-op span seam, so the startup path can accept a
tracer later and still stay inert now
> - The server gets a lazy tracer accessor, and the adapter timing
helper gets an injected tracer hook
> - The change keeps the default path free of OpenTelemetry and keeps
the existing startup event path unchanged
> - The benefit is a future-safe seam with no runtime change today
## Linked Issues or Issue Description
This PR addresses a feature gap in the sandbox startup path.
### Problem
Sandbox startup has no safe span seam. A direct OpenTelemetry import
would load telemetry packages on every run.
### Proposed Solution
Add a lazy tracer accessor in the server. Add an injected no-op tracer
seam in startup timing.
### Alternatives
Import OpenTelemetry directly in the startup path. Reject that path
because the default startup flow must stay inert.
## What Changed
- Added a lazy startup tracer accessor in
`server/src/instrumentation.ts`.
- Added an injected startup tracer seam in
`packages/adapter-utils/src/acpx-engine/startup-timing.ts`.
- Kept the startup event path unchanged.
- Kept `adapter-utils` free of OpenTelemetry imports.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/startup-timing.test.ts`
- `pnpm exec vitest run server/src/__tests__/instrumentation.test.ts`
- `tsc --noEmit` for `@paperclipai/adapter-utils` and
`@paperclipai/server`
## Risks
Low risk. The default tracer is a no-op, so the runtime path stays inert
until a later change injects a real tracer.
## Model Used
OpenAI GPT-5. Tool use and code execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Cloud and sandbox agents need less round-trip overhead at workspace
start
> - The workspace start path now uploads the git history and the working
tree overlay in two separate sync operations
> - That adds extra mkdir, guard, upload, and rename work for the same
workspace bytes
> - This pull request merges those two uploads into one guarded sync
operation
> - The benefit is one sync round trip for the workspace bytes with the
same guard and login-shell contract
## Linked Issues or Issue Description
No public GitHub issue exists for this change.
### Problem
A git-backed workspace start uploads the git-history clone and the
working-tree overlay as two separate host-to-sandbox sync operations.
### Proposed Solution
Merge the two uploads into one sync operation. Keep both tar mappings
under the same confinement guard. Run the git-history extract first,
then the overlay extract, then optional cleanup.
### Alternatives Considered
Keep two sync operations. That keeps the current round-trip cost and
duplicates the guard, upload, and rename work.
### Roadmap Alignment
This change supports the roadmap work on cloud and sandbox agents by
reducing workspace start overhead.
## What Changed
- Merge the git-history tar and the working-tree overlay tar into one
sync operation.
- Run the git-history extract first, then the overlay extract, then
optional remove-deleted-paths cleanup.
- Keep both temporary tar targets under the runtime directory so the
first extract cannot delete the second tar before use.
- Keep the symlink-escape guard, login-shell contract, and file-mapping
checks on the merged file set.
## Verification
- `tsc --noEmit` on `@paperclipai/adapter-utils`
- `@paperclipai/adapter-utils` full project test suite: 354 pass / 4
skipped
- Orchestrator proof: one merged operation with both tars and two
ordered extract commands
- Orchestrator proof: the confinement guard covers both tar mappings
- Daytona plugin `plugin.test.ts`: 94 pass
## Risks
- Any regression in the extract order could change workspace start
behavior.
- Any regression in the merged guard could block valid uploads or miss
an escape attempt.
## Model Used
OpenAI GPT-5, tool use enabled, current Codex session.

## Thinking Path
> - Paperclip is the control plane for AI agents.
> - Sandbox startup uses bridge directories and a Daytona workspace
handle.
> - The cold path made repeat directory creation calls and one avoidable
handle fetch.
> - Those calls add delay but do not change state.
> - This pull request folds the bridge directory setup into one exec,
removes redundant process-session setup, and seeds the Daytona handle
cache at acquire.
> - The benefit is fewer deterministic host-to-sandbox round trips and
faster cold starts.
## Linked Issues or Issue Description
- Problem: Cold sandbox start does extra directory creation work and
re-fetches a handle it already has.
- Expected result: The startup path should create each directory once
and reuse the fresh handle.
- Related PRs I found on GitHub: #9280, #9293.
## What Changed
- Added `makeDirs` to the bridge queue client and used one `mkdir -p`
exec for the callback bridge directories.
- Removed the two upfront `mkdir` execs for the process-session bridge
stdin and events directories.
- Seeded the Daytona sandbox handle cache at acquire so realize can
reuse the fresh handle.
- Reset the process-scoped cache in the compatibility test so the second
sync run sees the expected exec count.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec vitest run` - 351
passed, 4 skipped.
- `pnpm --filter @paperclipai/sandbox-provider-daytona exec vitest run`
- 91 passed.
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit` - clean.
- I checked `ROADMAP.md` for sandbox round-trip work. I found no
duplicate planned core work for this change.
## Risks
- Low risk. The change removes redundant calls and adds cache seeding.
- A wrong cache scope would hide the handle. The seed now checks the
lease scope and fails loudly.
- The daytona package `tsc --noEmit` still depends on SDK types that are
not installed in this isolated workspace. CI covers that path.
## Model Used
- OpenAI GPT-5, tool-using, with code execution in the current
workspace.

## What Changed
- Thread additional referenced-project sources through the run prepare
path and the runtime layers.
- Stage each referenced project into its own `project-<projectId>`
directory under the runtime root.
- Keep the anchor workspace history and overlay semantics unchanged.
- Fail closed on confinement or sync errors for one project, and keep
the other projects running.
- Keep the path inert by default behind the multi-project workspace-sync
kill-switch.
- No documentation update was needed for this code-only runtime change.

## Risks
- A referenced project can skip if confinement or sync fails.
- A new runtime tree layout can affect tools that assume one project
root.
- The kill-switch keeps the path inert until operators enable it.

### What happened?
The sandbox exec path kept a `noProfile` field after the exec wrappers
stopped sourcing a login profile.
### Expected behavior
The plugin protocol, server drivers, and managed-runtime helpers should
not expose or forward a dead field.
### Steps to reproduce
1. Run a managed-runtime command through the sandbox exec path.
2. Inspect the protocol payload and runtime helper inputs.
3. Observe that `noProfile` is present even though it no longer changes
behavior.
### Paperclip version or commit
`60c7da86fc7a6c1dbf37bbcd86e25ecaaff01607`
### Deployment mode
Built from source (pnpm dev / pnpm build)
### Additional context
This pull request removes the dead field, updates the affected tests,
and updates the README note for the sandbox profile path.
## What Changed
- Removed noProfile from the plugin protocol and the server exec-path
call sites.
- Updated the managed-runtime helpers to use the narrower exec-path
contract.
- Updated the affected tests and added the README pointer to

## Thinking Path
> - Paperclip keeps agent work on a controlled execution plane.
> - Sandbox exec wrappers run on the hot path for agent commands.
> - The current change removes the explicit `nvm.sh` load step from
those wrappers.
> - The sandbox image already restores PATH through profile startup.
> - This pull request keeps profile sourcing where the wrapper still
needs it and drops only the `nvm.sh` load step.
> - The result is a smaller command path with the same node and agent
CLI resolution.
## Linked Issues or Issue Description
No public GitHub issue exists for this change.
Problem:
The sandbox exec wrappers spent extra time sourcing `nvm.sh` before each
command.
The sandbox image already restores PATH in
`/etc/profile.d/00-restore-env.sh`, so that explicit `nvm.sh` work was
redundant.
Proposed solution:
Remove the `nvm.sh` source step from all six wrappers.
Keep the profile sourcing that the provider still needs for PATH setup.
Alternatives considered:
Keep the existing shell setup and accept the launch cost.
That keeps the current behavior, but it leaves the hot path slower than
needed.
Roadmap alignment:
This change keeps the sandbox command path small and predictable.
It does not change the adapter contract or the node resolution rules.
## What Changed
- Removed `nvm.sh` sourcing from all six sandbox exec wrappers.
- Kept profile sourcing where the provider still needs it for PATH
setup.
- Switched Modal to a non-login shell because the script now sources
profiles itself.
- Updated wrapper tests to assert that built commands do not source
`nvm.sh`.
## Verification
- Local TypeScript typecheck passed in each changed package.
- Focused provider tests passed for Daytona, E2B, Modal, exe-dev,
Cloudflare bridge, and adapter-utils.
- One Daytona test failure is pre-existing and unrelated to this change.
## Risks
- This change alters shell startup for sandbox exec paths.
- A provider that depends on implicit shell setup may need a follow-up.
- The current tests cover command shape, but they do not cover every
runtime shell path.
## Model Used
OpenAI Codex, GPT-5, tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The sandbox runtime depends on efficiently staging files into remote
environments
> - The process-session bridge was rewriting a static remote script on
every start, even when the remote copy already matched
> - That caused unnecessary round trips and made the startup path
noisier than it needed to be
> - This pull request adds a hash-skip path for the process-session
script write and keeps the existing bridge-entrypoint hash gate on the
same helper
> - It also locks in the reduced inbound round-trip count so the
collapse from the prior PR cannot silently regress
> - The benefit is fewer remote execs on warm starts and a stronger
guard against performance regressions
## Linked Issues or Issue Description
- Refs: https://github.com/paperclipai/paperclip/pull/10354
### Feature request-style description
**Subsystem affected**
- Cross-cutting (packages/adapter-utils and sandbox staging helpers)
**Problem or motivation**
- The process-session bootstrap path was rewriting a static remote
script on every start even when the remote file already matched the host
content.
- That added avoidable remote execs and latency to warm starts.
- The inbound staging collapse from the previous PR also needed a
regression lock so it could not silently drift back to extra round
trips.
**Proposed solution**
- Route the process-session remote script upload through the existing
hash-skip helper used by the sandbox callback bridge entrypoint.
- Keep the bridge-entrypoint behavior unchanged by delegating it to the
same helper.
- Add a regression test that asserts the inbound staging path still
collapses to the expected round-trip count.
**Alternatives considered**
- Keep the existing unconditional write path and accept the extra execs
on warm starts. Rejected because it preserves avoidable overhead.
- Add a second specialized helper just for process-session scripts.
Rejected because the bridge-entrypoint logic already solved the same
problem and should stay aligned.
**Roadmap alignment**
- This fits the roadmap items around cloud/sandbox agents and enforced
outcomes by reducing bootstrap waste and preventing performance
regressions.
- It does not introduce new product surface area, telemetry, or
user-facing workflow changes.
**Additional context**
- The implementation preserves the existing upload/verify/rename
behavior when the remote content differs and only skips the write when
the hash already matches.
- PR #10354 collapsed the inbound staging path; this PR preserves that
win.
## What Changed
- Added a shared hash-skip helper for remote text-file synchronization
so unchanged content skips the write path after a single remote hash
check.
- Switched the process-session remote script upload to use that helper,
preserving the existing write/verify/rename behavior when the remote
content differs.
- Refactored the sandbox callback bridge entrypoint sync to use the same
helper without changing its observable behavior.
- Added a mocked-native-runner regression test that locks the inbound
staging path to one `client.syncIn` round-trip per step and zero direct
write/run execs.
## Verification
- `tsc --noEmit`
- `pnpm --filter @paperclipai/adapter-utils exec vitest run`
- Full adapter-utils vitest sweep: 338 passed / 4 skipped
## Risks
- Low risk: the helper changes when a write occurs, not the script
contents or the remote execution surface.
- A hash-check failure now fails loudly instead of silently rewriting,
which is safer but could surface provider-side issues earlier than
before.
- The regression test is intentionally specific to the current collapsed
staging path, so future architectural changes will need test updates.

## Thinking Path
> - Paperclip is the control plane for autonomous AI companies
> - The Daytona adapter turns tasks into shell commands and manages
execution overhead
> - Many short-lived exec calls still pay for login-shell profile
sourcing even when the binary already resolves on the sandbox default
PATH
> - That extra startup work adds latency on the hot path for repeated
command execution
> - This pull request adds an opt-in fast path that skips profile
sourcing only when the caller explicitly requests it and the command
does not need shell initialization
> - The benefit is lower per-call latency for eligible commands without
changing the conservative default behavior for commands that need the
profile
## Linked Issues or Issue Description
This change does not reference a public GitHub issue. It follows the
same Daytona startup-speed work as merged PR #10335 and narrows the
execution path for eligible commands while keeping the default
login-shell behavior intact.
## What Changed
- Added an optional `noProfile` flag to
`PluginEnvironmentExecuteParams`.
- Refactored Daytona login-shell script assembly so the profile and nvm
sourcing block is omitted only on the explicit fast path.
- Preserved environment prefixing, `cd`, shell quoting,
`NONINTERACTIVE_GIT_ENV`, stdin handling, and `durationMs` behavior on
both paths.
- Added regression tests for the fast path omission, the preserved
execution parameters, and the default profile-sourcing path.
## Verification
- `pnpm --filter @paperclipai/sandbox-provider-daytona exec vitest run
src/plugin.test.ts`
- `pnpm --filter @paperclipai/plugin-sdk tsc --noEmit`
- Reverted the guard locally to confirm the two behavior tests fail
again, then restored the change.
## Risks
- If a caller opts into `noProfile` for a command that depends on shell
initialization, the command can fail to resolve its binary.
- The API comment and opt-in design keep that risk narrow; the default
path remains unchanged.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents make progress in heartbeats: the server wakes an agent
session, it does a slice of work on an issue, records a disposition, and
exits
> - Benchmarking identical coding tasks run as Paperclip-orchestrated
agent pairs vs invoking the same agent harness directly measured a
1.8–2.2× wall-clock slowdown for the Paperclip pairs, dominated by
per-heartbeat orchestration overhead rather than model time
> - Two contributors stood out: (1) since PF-4 (#4838) every
`heartbeat_timer` wake starts a brand-new task session, so continuation
work on a specific issue repays the full session-start and
re-orientation cost on every heartbeat; (2) in degraded environments
agents burn many tool calls retrying the same failing control-plane
write before giving up
> - This pull request reuses the task session for issue-scoped timer
wakes (keeping the PF-4 fresh-session rule only for unscoped exploratory
wakes, which were the original context-bloat case) and adds a
bounded-retry rule to the wake prompt and core skill: after 2
consecutive failures of the same control-plane write, stop retrying it
for the rest of the heartbeat and rely on the adapter/runtime status
channel
> - The benefit is materially less wall-clock and token overhead per
heartbeat while preserving the context-bloat protection PF-4 was added
for
## Linked Issues or Issue Description
Refs #4838 (merged PF-4 change whose reset rule this refines), Refs
#5287, Refs #1907 (related timer-heartbeat session work).
No public GitHub issue exists for the slowdown itself; bug-report
fields:
- **What happened:** Agent pairs orchestrated through Paperclip
heartbeats complete identical task sets 1.8–2.2× slower (wall-clock)
than the same harness invoked directly. Profiling attributed the gap to
per-heartbeat orchestration overhead: every timer wake discards the task
session (full session start + re-orientation), and in degraded
environments agents repeatedly retry the same failing control-plane
write.
- **Expected behavior:** Heartbeat orchestration should add minimal
wall-clock overhead on top of the underlying harness; issue-scoped
continuation work should not pay a fresh-session tax each interval.
- **Steps to reproduce:** Run a fixed benchmark task set once through
Paperclip issue heartbeats and once via direct harness invocation with
the same model/config; compare wall-clock totals.
- **Version/commit:** master @ 3d23c3b2c3, self-hosted deployment.
## What Changed
- `server/src/services/heartbeat.ts`: `shouldResetTaskSessionForWake`
now resets only for `heartbeat_timer` wakes with no derivable task key
(unscoped exploratory wakes). Issue-scoped timer wakes reuse the issue's
task session. `describeSessionResetReason` updated to stay in exact
agreement.
- `server/src/__tests__/heartbeat-timer-wake-session-reset-pf4.test.ts`:
new cases for scoped vs unscoped timer wakes, plus the scoped case added
to the reset/reason agreement invariant.
- `packages/adapter-utils/src/server-utils.ts`: wake prompt template and
execution contract gain a bounded-retry rule — after 2 consecutive
failures of the same control-plane write, stop retrying it for the rest
of the heartbeat, continue useful work, report the failure in the final
response, and use the adapter/runtime status channel as the sanctioned
fallback.
- `packages/adapter-utils/src/server-utils.test.ts`: asserts the new
prompt lines are present in both the template and the rendered wake
prompt.
- `skills/paperclip/SKILL.md`: documents the same bounded write-retry
rule in the core Paperclip skill.
## Verification
- `node_modules/.bin/vitest run
packages/adapter-utils/src/server-utils.test.ts` — 1 file, 83 tests
passed
- `cd server && node_modules/.bin/vitest run
src/__tests__/heartbeat-timer-wake-session-reset-pf4.test.ts` — 1 file,
14 tests passed
- Both run on this branch rebased onto current master (3d23c3b2c3)
## Risks
- Behavioral shift: issue-scoped timer wakes now reuse sessions, so a
long-lived issue session can grow across heartbeats. Mitigated by
keeping the PF-4 reset for unscoped wakes (the originally observed bloat
case) and by existing session compaction.
- Prompt/skill text changes alter agent guidance; the new rule is scoped
narrowly to repeated failures of the same control-plane write.
- No migrations, no API or schema changes, no dependency changes.
## Model Used
- Claude (Anthropic) — `claude-fable-5` (Fable 5), extended reasoning
with tool use, driven via Claude Code / Claude Agent SDK.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter/runtime layer has to move files into sandboxes safely
and efficiently
> - The current sync-in path needs a provider-delegable seam so
providers can use their native upload transport when available
> - The upload contract also needs ordered post-upload commands so
extracted content can be finalized fail-fast after transfer
> - The fallback path still has to preserve current behavior when the
provider does not expose native sync verbs
> - This pull request adds the contract and runtime seam for
provider-delegable sync-in, plus the single-stream collapse flag
> - The benefit is fewer round trips, a cleaner provider-owned upload
path, and a compatible fallback for existing runners
## Linked Issues or Issue Description
No public GitHub issue exists for this change. The underlying feature
request is described below in the repository's feature-request format.
### Problem or motivation
Paperclip needs a sync-in path that lets each provider choose the best
available upload transport instead of forcing the harness to orchestrate
uploads the same way every time. The runtime also needs a way to
describe ordered post-upload commands so providers can finalize
extracted content fail-fast after transfer.
### Proposed solution
Extend the sync contract with ordered post-upload commands, forward that
contract through the plugin and environment runtime layers, and make
client syncIn always available. When a provider advertises native sync
verbs, the client should delegate to that transport; otherwise it should
fall back to the existing tarball/write/extract behavior and then run
the post-upload commands in order.
### Alternatives considered
Keeping upload orchestration entirely host-side would avoid a contract
change, but it would block provider-specific transport optimizations and
keep the harness responsible for a path the provider can do more
efficiently. A separate post-upload API would add another surface
without improving the existing sync flow.
### Roadmap alignment
This work aligns with the broader runtime and adapter roadmap because it
improves provider integration without changing the external product
model. It is an additive contract change that preserves backward
compatibility for providers that do not expose native sync verbs.
### Additional context
The fallback path still needs to preserve existing observable behavior,
including command ordering, cwd confinement, and fail-fast execution.
The single-stream progress flag is part of the same transport
improvement so smaller writes can collapse to a single round trip when
the runner supports it.
## What Changed
- Added ordered `postUploadCommands` support to the sync operation
contract and SDK mirror.
- Plumbed the sync-in contract through the plugin and environment
runtime layers.
- Implemented a runtime client `syncIn` path that delegates to native
provider transport when available, otherwise uses the generic
tarball/write/extract fallback.
- Preserved fail-fast execution of ordered post-upload commands in the
fallback path.
- Flipped the sandbox runner's single-stream stdin progress flag to
collapse small `writeFile` operations to a single round trip.
- Added and updated tests for contract forwarding, fallback behavior,
cwd rejection, fail-fast behavior, and single-stream collapse.
## Verification
- `pnpm --filter @paperclipai/plugin-sdk exec vitest run
protocol.postupload.test.ts`
- `pnpm --filter @paperclipai/plugin-sdk exec vitest run
environment-sync-negotiation.test.ts`
- `pnpm --filter @paperclipai/adapter-utils exec vitest run
command-managed-runtime.test.ts`
- `pnpm --filter @paperclipai/server exec vitest run
environment-execution-target.test.ts`
- Local typecheck and targeted suite runs reported in the handoff passed
before PR creation.
## Risks
- The new fallback path could diverge from the previous inline upload
behavior if the tarball/extract contract changes.
- Provider-native sync handling may expose provider-specific edge cases
if a runner advertises sync verbs but does not fully honor the contract.
- The single-stream flag changes transport behavior for small uploads,
so regressions would likely show up as round-trip or upload failures.

## Thinking Path
> - Paperclip runs AI-agent work through adapter-backed execution paths.
> - Sandbox-backed local adapters pay startup overhead in two host-side
bridge setups.
> - Those setups were happening serially even though most of the work is
independent.
> - The remaining dependency is only the merged env that must reach the
process-session launch.
> - This pull request overlaps the independent setup work while
preserving that launch-time dependency.
> - The benefit is lower end-to-end startup latency without changing
execution semantics.
## Linked Issues or Issue Description
No public GitHub issue exists for this change.
Problem / motivation:
- Sandbox-backed local adapter startup waited for two largely
independent bridge setups in series, so users paid roughly the sum of
both setup times.
- The only hard dependency is the merged Paperclip env that must reach
the process-session launch.
Proposed solution:
- Start the paperclip callback bridge and the process-session bridge
concurrently.
- Keep the env merge as the single sequencing point before
process-session launch.
- Stop whichever bridge started if either startup path fails.
- Keep the concurrent bridge telemetry duration-only so shared runner
counters are not double-counted.
Alternatives considered:
- Keep the bridges serial, which preserves the current telemetry shape
but leaves the startup latency unchanged.
- Move env merging earlier, which would complicate launch ordering and
risk changing runtime semantics.
Roadmap alignment:
- This is the approved Daytona start-speedup work, focused on bridge
startup concurrency rather than broader runtime behavior.
## What Changed
- Started the paperclip callback bridge and the process-session bridge
concurrently in `execute.ts`.
- Added a memoized env finalizer so the process-session launch still
waits for the merged paperclip env at the correct moment.
- Updated `execution-target.ts` so the process-session bridge can accept
a deferred env resolver and consume it only at launch time.
- Added tests that cover the overlapped launch path and the
failure-cleanup path when one bridge start fails.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec vitest run
src/acpx-engine/execute.test.ts`
- `pnpm --filter @paperclipai/adapter-utils test`
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit`
- `git log --oneline
origin/master..origin/perf/parallelize-daytona-bridge-setups`
- `git diff --stat
origin/master...origin/perf/parallelize-daytona-bridge-setups`
## Risks
- A regression in the launch-time env merge could change what the
process-session bridge sees at startup.
- The concurrent start/cleanup logic could leak a bridge if the stop
paths were incorrect, which is why the failure cleanup test matters.
- This is low-to-moderate risk because the change is isolated to
adapter-utils startup plumbing and is covered by targeted tests.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox-backed runs need more precise startup observability so
operators can see where time is spent before an adapter is invoked
> - Aggregate startup timing hides which boundary is actually slow,
especially in remote execution where the bottleneck can move between
host round-trips, provider-boundary latency, and handshake phases
> - This pull request keeps the existing startup timing channel additive
while attributing the latency to the specific startup steps that caused
it
> - The benefit is better diagnosis of sandbox startup regressions
without changing control flow or introducing a schema migration
## Linked Issues or Issue Description
Refs: #10204
This PR extends the existing sandbox run-startup timing observability
with per-step round-trip and provider-latency attribution for the
Daytona startup path. It keeps the event payload additive and free-form,
and it leaves the control flow, database schema, and external adapter
interfaces unchanged.
## What Changed
- Added per-step round-trip counting for the host-to-sandbox execute
seam
- Added provider-boundary duration accumulation for the Daytona execute
and re-fetch steps
- Split the ACP handshake timing into `createRuntimeMs` and
`ensureSessionMs` while preserving the warm-handle skip
- Kept the startup timing payload additive and did not add a schema
migration
## Verification
- `adapter-utils` acpx-engine and startup-timing suites: pass
- Daytona plugin suite: pass with mocked SDK and injected-clock duration
assertions
- `server` environment-execution-target suite: pass
- `tsc --noEmit` for adapter-utils and server: pass
- Git validation: fetched
`origin/feat/sandbox-start-step-timing-attribution`, confirmed it
matches the authorized submit SHA
`53c573266e618af05c57a0720aaa9d9e0452de61`, and confirmed the branch
contains only the expected commit on top of `origin/master`
- Searched GitHub for duplicate or related PRs/issues; found one closely
related merged PR and no open duplicate on this branch
- Checked `ROADMAP.md`; the broad sandbox-agent roadmap section does not
call out this specific startup-timing attribution work as a duplicate
## Risks
- Low risk: the change is additive and only enriches existing timing
data
- Downstream consumers that assume aggregate-only startup timing may
need to tolerate the additional per-step fields
- The finer spawn/initialize/session split remains a follow-up in the
external ACP client because that hook is not available here yet

## Thinking Path
> - Paperclip is the open source control plane people use to manage AI
agents for work
> - Local process adapters can enforce network allowlists through a
Unix-socket proxy inside the Linux sandbox
> - The proxy socket was created under `os.tmpdir()`, which can be a
deeply nested run-specific directory
> - Linux Unix-domain socket paths are limited to 107 usable bytes, so
deep temporary paths can be silently truncated during bind
> - A truncated proxy socket resets every confined outbound connection,
including the model provider API, before the agent can do work
> - This pull request creates proxy sockets under the short `/tmp` path
when possible and validates the path length before bind
> - The benefit is reliable sandboxed egress under deep `TMPDIR` values
and an explicit error instead of an opaque connection-reset storm
## Linked Issues or Issue Description
### Pre-submission checklist
- [x] I searched existing open and closed issues and this is not a
duplicate.
- [x] I can reproduce this on upstream `master`.
- [x] I confirmed the error originates in Paperclip's local-process
sandbox proxy.
### What happened?
Sandboxed local-process agents using `networkScope: "allowlist"` could
lose all proxied egress when `TMPDIR` was deeply nested because
`proxy.sock` exceeded Linux's Unix socket path limit. The truncated bind
surfaced as repeated connection resets, including for provider API
traffic.
### Expected behavior
Proxy creation should use a Linux-safe short path and fail explicitly if
no safe socket path can be created.
### Steps to reproduce
1. Set `TMPDIR` to a path long enough that
`<TMPDIR>/paperclip-network-sandbox-XXXXXX/proxy.sock` exceeds 107
bytes.
2. Build or run a local-process sandbox with `networkScope:
"allowlist"`.
3. Make an HTTP or HTTPS request through the generated sandbox proxy.
4. Observe connection resets from the overlong Unix socket path on
affected code.
### Paperclip version or commit
Upstream `master` before this change.
### Deployment mode
Other — Linux local-process adapters using Bubblewrap network
allowlisting.
### Installation method
Built from source.
### Agent adapter(s) involved
Codex and any other local-process adapter using the shared sandbox
utility.
### Operating system
Linux.
### Additional context
GitHub search found no duplicate public issue or pull request for this
defect.
## What Changed
- Add a Linux Unix-socket byte-length guard that reports the unsafe path
before binding.
- Create network proxy temporary directories under `/tmp` first, with
`os.tmpdir()` as a validated fallback.
- Use the safe temporary-directory helper at both allowlist proxy
creation sites while preserving trusted URL handling.
- Add regression coverage that sets a deliberately deep `TMPDIR` and
verifies the working socket remains within 107 bytes under `/tmp`.
## Verification
- `node
/srv/paperclip/home/paperclipai/paperclip/node_modules/vitest/vitest.mjs
run packages/adapter-utils/src/local-process-sandbox.test.ts` — 8
passed, 4 environment-gated tests skipped.
- `git diff --check origin/master...HEAD` — passed.
- Greptile Review — passed after reviewing 2 files with 0 comments and
no unresolved threads; this repository integration did not emit a
separate numeric confidence score.
- Full GitHub CI matrix — passed after one rerun of an unrelated ACPX
`ENOTEMPTY` cleanup flake.
- Package typecheck was attempted, but the existing shared install
cannot resolve `acpx/runtime`; the failure is outside the changed files
and is expected to be covered by CI's clean dependency install.
## Risks
- Low risk: the change is limited to Linux sandbox proxy
temporary-directory selection and validation.
- Systems without a writable `/tmp` fall back to `os.tmpdir()` only when
the resulting socket path is safe; otherwise startup now fails loudly
instead of producing connection resets.
- No schema, API, UI, migration, or documentation behavior changes.

## Model Used
- OpenAI Codex, `gpt-5.3-codex`, tool-enabled coding agent with managed
reasoning and code execution; context-window size is not exposed by the
runtime.

## Thinking Path
> - Paperclip is the control plane people use to coordinate AI agents
and their execution environments.
> - Environment realization decides where an agent runs and which
filesystem and toolchain are authoritative.
> - Copy-based realization is unsafe for container-anchored tasks
because absolute paths such as `/app` can point outside the synchronized
tree and task-specific binaries may be absent.
> - That mismatch can let an agent successfully verify work in a phantom
writable path while sync-back silently discards the result.
> - Existing task environments already provide the authoritative
filesystem and toolchain, so they should be executed in place rather
than copied.
> - Copy mode still needs explicit confinement rules so aliases target
the synchronized workspace and unsynchronized writable paths fail
visibly.
> - This pull request adds typed realization metadata, propagates the
authoritative root through orchestration, and teaches Codex to honor it.
> - The benefit is that container-anchored tasks operate on
verifier-visible state with the intended tools, while copy mode remains
safe and backward compatible.
## Linked Issues or Issue Description
No public GitHub issue exists for this defect.
GitHub duplicate searches for in-place execution, workspace realization,
and authoritative workspace roots found no related pull request to link.
### What happened?
Environment-backed agent runs were always realized through a copied
workspace. Tasks anchored to absolute container paths could therefore
write outside the synchronized tree, and task-provided toolchains were
unavailable in the copy. A run could report success even though
sync-back discarded its output.
### Expected behavior
Existing task environments should run against their real authoritative
root and toolchain. Copy-mode runs should map declared absolute aliases
into the synchronized tree and reject writable paths that cannot be
restored.
### Steps to reproduce
1. Run a Codex task environment whose required files live under `/app`
or `/workspace` and whose required binary exists only in the task
container.
2. Observe that copy realization changes the effective
filesystem/toolchain or permits writes outside the synchronized root.
3. Complete and verify the task inside the agent sandbox.
4. Observe that the verifier cannot see out-of-tree artifacts or that
task-specific commands were unavailable.
### Reproduction context
- Paperclip commit: `3a16b91217483d2c233926de5b7f7bc3a1077924`
- Deployment: built from source in a task-container execution
environment
- Adapter: Codex local
- Database: not database-related
- Access context: agent execution
## What Changed
- Added typed `copy | in_place` workspace-realization metadata,
authoritative roots, confined aliases, and outbound restore paths to
shared execution-target contracts.
- Selected in-place realization for existing task environments and
skipped archive prepare/restore when the authoritative environment is
used directly.
- Propagated the authoritative root into adapter context so Codex uses
it for cwd and `PAPERCLIP_WORKSPACE_*` semantics, including ACP
execution.
- Bound copy-mode aliases such as `/app` to the synchronized workspace
and rejected writable out-of-tree paths without explicit restore
mappings.
- Added focused regression coverage while preserving existing copy-mode
archive restore behavior.
## Verification
- `pnpm --filter @paperclipai/shared typecheck` — passed.
- `pnpm exec vitest run
packages/adapter-utils/src/local-process-sandbox.test.ts
packages/adapters/codex-local/src/server/acp.test.ts
packages/adapters/codex-local/src/server/execute.remote.test.ts
server/src/__tests__/environment-run-orchestrator.test.ts` — 48 passed,
4 skipped.
- `pnpm -r typecheck` — passed.
- `env -u AWS_ACCESS_KEY_ID -u AWS_SECRET_ACCESS_KEY -u
AWS_SESSION_TOKEN pnpm test:run` — passed across all general and
serialized Vitest shards.
- `pnpm build` — passed.
- Codex `k=1` acceptance run completed July 24, 2026 at 23:54:30 UTC
with 4 completed, 0 exceptions, and mean reward 1.0: `build-cython-ext`,
`openssl-selfsigned-cert`, `prove-plus-comm`, and `sqlite-db-truncate`
each received terminal grade 1.0 against real task-environment paths and
toolchains.
## Risks
- In-place mode deliberately exposes the authoritative task root to the
adapter; incorrect environment metadata could point execution at the
wrong root. Typed metadata and focused orchestration tests cover
selection and propagation.
- Copy-mode writable-path validation is stricter and may reject
previously accepted unsafe configurations. The rejection is intentional
and produces a visible error instead of silently losing output.
- The acceptance run is focused on four Codex task-environment
workloads, not a broad cross-adapter benchmark. Existing copy-mode
archive tests and the full repository suite remain green.

## Model Used
- OpenAI Codex CLI coding agent; exact model ID and context-window size
were not exposed to this runtime. Capabilities used: extended reasoning,
repository editing, shell execution, test/build execution, Git, GitHub
CLI, and Paperclip API tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Heartbeat wake payloads and the task-context markdown are the two
channels that deliver an issue's brief into an agent's prompt
> - #10151 fixed wake-prompt-only adapter lanes waking without the issue
description by adding it to the structured wake payload
> - That left the description delivered twice per prompt on lanes that
also inject the task-context markdown, and re-delivered in full on every
resume wake, permanently bloating persistent-session context
> - This pull request makes the task markdown the single description
carrier on lanes that use it, and omits the description from
non-assignment resume deltas on all lanes while keeping it for
assignment-shaped and recovery wakes
> - The benefit is that every lane receives the brief exactly once when
it needs it, and long-lived sessions stop re-paying the full brief in
tokens on every wake
## Linked Issues or Issue Description
Refs #10151
Related prior work: #2883, #8402 (earlier description-delivery attempts
referenced by #10151). I searched the PR list for open work on
wake-payload description handling and found none besides the merged
#10151.
**Bug:** After #10151, adapters that inject the `Paperclip task context`
markdown (ACPX engine lanes, claude-local CLI, hermes server and
gateway) receive the issue description twice in a single prompt — once
in the wake prompt's `Issue description:` block and once in the task
markdown. Separately, resume deltas re-send the full description (up to
12k characters) on every wake even though the persistent session already
received it.
**Expected behavior:** The description appears exactly once per prompt
on every lane, and resume deltas only carry it when the resuming session
may not have seen the brief (assignment-shaped or recovery wakes),
leaving an explicit fetch breadcrumb otherwise.
**Reproduction:** Wake a claude-local or ACPX agent on an issue with a
description and inspect the assembled prompt: the description text
appears in both the wake-payload block and the task-context block. Wake
the same session again via a comment: the full description is present
again in the resume delta.
**Affected version:** Current `master` (with #10151 merged).
**Deployment mode:** Adapter-backed heartbeat execution, local and
sandboxed lanes.
## What Changed
- `renderPaperclipWakePrompt` accepts `suppressIssueDescription`; the
four task-markdown lanes pass it so the task markdown stays the single,
uncapped description carrier there.
- Non-assignment resume deltas omit the description and emit `- issue
description: omitted from this resume delta; fetch the issue if you need
the latest brief`. Assignment-shaped reasons (`issue_assigned`,
`issue_reopened_via_comment`, `issue_recovery_action_restored`,
`issue_tree_restored`) and recovery wakes still deliver the full brief.
- `buildPaperclipTaskMarkdown` gains `includeDescription`; the server
now also publishes `context.paperclipTaskMarkdownCompact` (description
stripped, directives and wake comment kept), and the new
`selectPaperclipTaskMarkdown` helper picks the right variant under the
same resume rules, falling back to the full markdown when no compact
variant exists (version skew safety).
- The wake prompt's description block now carries the same user-authored
trust framing the task markdown already had.
## Verification
- `npx vitest run packages/adapter-utils/src/server-utils.test.ts
packages/adapters/claude-local/src/server/acp.test.ts
packages/adapters/codex-local/src/server/acp.test.ts
server/src/__tests__/heartbeat-context-summary.test.ts` — 137 tests
passed, including new coverage for suppression, resume omission plus
breadcrumb, assignment-shaped resume inclusion, compact-variant
building, variant selection, and an end-to-end ACPX prompt-assembly test
asserting the description appears exactly once on fresh wakes and not at
all on comment resumes.
- `npx vitest run` in `packages/adapters/hermes` — 59 tests passed,
including a gateway execute-level test asserting the brief is sent
exactly once on fresh runs and not re-sent on stable-session resumes.
- `tsc --noEmit` in `packages/adapter-utils`,
`packages/adapters/claude-local`, `packages/adapters/hermes` — clean;
`server` matches the `master` baseline exactly (pre-existing plugin-sdk
resolution errors only, none in touched files).
- Pre-existing failures confirmed identical on clean `master`:
claude-local `execute.remote.test.ts` / `test.probe.test.ts`,
adapter-utils `mcp-isolation.integration.test.ts` (requires a newer
local Claude CLI).
## Risks
- Behavioral shift, prompt-only: a resumed session woken by a comment on
an issue it never handled (rare — assignment wakes normally precede
comment wakes) would not get the inline description; the breadcrumb plus
the standard issue-fetch path covers it.
- Additive context key (`paperclipTaskMarkdownCompact`); older adapters
ignore it and newer adapters fall back to the full markdown when it is
absent, so mixed-version deployments degrade to current behavior.
- No schema, migration, or API changes; the structured wake-payload JSON
shape is unchanged.
- Known follow-up deliberately out of scope: openclaw embeds the raw
wake-payload JSON (which still contains the description) in prompt text
for machine parsing. The hermes-gateway lane is handled: it detects
stable-session resumes (issue/agent session-key strategy plus a stored
prior session id), compacts the task markdown, and omits the description
from its prompt-embedded JSON copy.
> This is a focused correctness/efficiency fix to existing wake plumbing
and does not overlap with planned roadmap feature work.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Heartbeat wake payloads provide the scoped task context an agent
needs before it can act safely
> - Assignment wakes already loaded the issue description for task
markdown, but the structured wake-payload builder dropped it

missing brief while also being told no fallback fetch was needed

adapter contract, and marks truncated descriptions as requiring fallback
fetch

inventing requirements from the title
## Linked Issues or Issue Description
Fixes: #5844Fixes: #2882
Related prior attempts: #2883 and #8402. This change adds focused
regression coverage and enforces the missing long-description fallback
invariant.
**Bug:** Issue-assignment wake payloads omitted the issue description
from the structured payload even when the issue had a populated
description.
**Expected behavior:** The structured wake payload includes the issue
description. If the description must be truncated for payload size,
`fallbackFetchNeeded` is `true`.
**Reproduction:** Assign an issue with a description to an agent and
inspect `PAPERCLIP_WAKE_PAYLOAD_JSON`; before this change,
`issue.description` was absent while `fallbackFetchNeeded` could remain
`false`.
**Affected version:** Reproduced on current `master` before this patch.
**Deployment mode:** Adapter-backed heartbeat execution, including local
Codex agents.
## What Changed
- Include `issues.description` in the server wake-payload query and
supplied issue summaries.
- Bound inline descriptions at 12,000 characters and force fallback
fetch when truncation occurs.
- Preserve and render description metadata through shared adapter
normalization and prompt rendering.
- Add focused tests for long-description fallback and exact brief-string
rendering.
## Verification
- `pnpm exec vitest run
server/src/__tests__/heartbeat-agent-session-message.test.ts
packages/adapter-utils/src/server-utils.test.ts` — 81 tests passed.
- `pnpm --filter @paperclipai/adapter-utils typecheck` — passed.
- `pnpm --filter @paperclipai/server typecheck` — passed.
- `git diff --check` — passed.
## Risks
- Low risk: the payload shape is additive.
- Very long descriptions are truncated at 12,000 characters; the payload
explicitly requests a fallback fetch for the full brief.
- Prompt size increases by the issue-description length for scoped
wakes, bounded by the same limit.
> This is a focused correctness fix and does not overlap with planned
roadmap feature work.
## Model Used
- OpenAI GPT-5.4 via Codex CLI, with reasoning, repository tool use,
shell execution, and test execution. The runtime did not expose a
context-window size.

## Thinking Path
> - Paperclip is the open source control plane people use to manage AI
agents for work
> - Local coding adapters can be confined with filesystem and network
sandbox policies
> - Codex confinement proxied only user-allowlisted hosts, so it denied
Paperclip's own run API and managed MCP endpoints
> - The same proxy returned untyped plaintext denials, which MCP clients
could treat as a fatal unexpected content type
> - Host-only `PAPERCLIPAI_CMD` values could also leak into agents even
when the referenced checkout module did not exist
> - This pull request gives the sandbox an explicit trusted-URL channel
for Paperclip endpoints, returns structured JSON errors, and removes the
inherited host CLI pointer
> - The benefit is confined Codex agents retain control-plane access
without broadening the operator's external network allowlist or crashing
on policy denials
## Linked Issues or Issue Description
Refs #3802
Related foundation: #9504
### What happened?
A `codex_local` agent configured with `networkScope: "allowlist"` and an
external-only allowlist could not reach its own Paperclip API or
Paperclip-managed MCP endpoints. The sandbox proxy returned a `403`
plaintext response without `Content-Type`, and an inherited
`PAPERCLIPAI_CMD` could point at a missing checkout-local CLI module.
### Expected behavior
Paperclip's run-scoped API and managed MCP endpoints remain reachable
regardless of the user external allowlist. Policy denials are valid
structured JSON responses with an explicit media type, and host-only CLI
pointers are not inherited by agent processes.
### Steps to reproduce
1. Configure a `codex_local` agent with `networkScope: "allowlist"` and
`networkAllowlist: ["api.openai.com"]`.
2. Run the agent and request its Paperclip issue API or a
Paperclip-managed MCP endpoint.
3. Observe the sandbox proxy deny the request with an untyped plaintext
`403` response.
### Environment
- Paperclip commit: `f49a3f99` originally exhibited the defect; fix is
based on current `master`.
- Deployment: local source build on Linux.
- Adapter: Codex.
- Database: not database-related.
- Access context: agent bearer/run-scoped credentials.
## What Changed
- Added internal trusted URL rules to the local network allowlist proxy
and supplied the Codex run API plus managed MCP endpoints.
- Returned JSON error envelopes with `Content-Type` and `Content-Length`
for HTTP and CONNECT policy denials.
- Removed inherited `PAPERCLIPAI_CMD` from child process environments
while preserving explicitly constructed runtime variables.
- Added focused proxy and environment sanitizer regression tests.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/local-process-sandbox.test.ts
packages/adapter-utils/src/server-utils-env.test.ts --reporter=verbose`
- 2 test files passed; 8 tests passed; 4 platform-dependent tests
skipped.
- `git diff --check`
- Package typecheck was attempted; it reaches unrelated current-`master`
type drift in untouched files (`spawnCwd` in `adapter-utils`, and
staged-runtime ACP types in `codex-local`).
## Risks
- Low risk: trusted access is restricted to exact HTTP(S) hostname and
port pairs derived from Paperclip-provided URLs.
- Invalid or non-HTTP trusted URL values are ignored rather than
broadening access.
- Denial response bodies change from plaintext to structured JSON;
status codes remain unchanged.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox-backed runs need observable startup behavior so operators
can see where time is spent before an adapter is invoked
> - The current startup path only surfaced aggregate timing, which makes
it hard to identify the slow boundary in the bring-up sequence
> - That gap matters because sandbox startup latency is often dominated
by one specific step, and aggregate timing hides the bottleneck
> - This pull request adds per-step startup timing events for the named
sandbox bring-up boundaries
> - The benefit is more precise observability with no control-flow
change and no schema migration
## Linked Issues or Issue Description
### Subsystem affected
Cross-cutting (multiple of the above)
### Problem or motivation
Sandbox run startup only exposed aggregate timing. That makes it hard to
identify which bring-up boundary is responsible for slow starts,
especially in remote or sandboxed execution where the bottleneck can
move between workspace setup, skill reconciliation, bridge setup, and
adapter handshake.
### Proposed solution
Emit a structured timing event for each named startup boundary before
the adapter is invoked, so the existing run-event stream carries
per-step duration data. This keeps the event path additive and lets
operators see which step dominates startup latency without changing
control flow or introducing a schema migration.
### Alternatives considered
- Keep only the aggregate startup duration: simpler, but it hides the
bottleneck and makes regression analysis much harder.
- Add a new telemetry sink or schema field: rejected because the
existing run-event payload already carries structured event data and
does not need a new storage path.
- Log unstructured text for each step: rejected because it is harder to
query and aggregate than a structured `step` + `durationMs` event.
### Roadmap alignment
This fits the roadmap direction around cloud / sandbox agents and
enforced outcomes by improving observability for sandboxed execution
without changing the control plane model. The roadmap section is broad,
but it does not call out this specific startup-timing work as a planned
duplicate.
### Additional context
This PR is intentionally additive. It records timing for the named
startup boundaries in the existing event stream and leaves the bridge,
database shape, and adapter invocation order unchanged.
## What Changed
- Added a `measureStartupStep` helper that times a startup step, emits
one structured `run.startup.step` event, and rethrows failures after
recording duration
- Wrapped the seven sandbox bring-up boundaries in `execute.ts` so the
structured timing covers each named step before adapter invocation
- Added unit coverage for the helper and integration coverage for the
startup-step events in the adapter-utils execute path
- Kept the event path additive, with no bridge change and no database
migration
## Verification
- `tsc --noEmit` for `@paperclip/adapter-utils`
- `pnpm test` in `packages/adapter-utils` equivalent suite coverage: 292
passed, 4 skipped
- Adjacent server event/log-store suites: `run-log-store.test.ts` and
`heartbeat-run-log.test.ts` passed (11 total)
- Git validation: fetched `origin/feat/sandbox-startup-step-timing`,
confirmed it matches the authorized submit SHA, and confirmed
`origin/master..origin/feat/sandbox-startup-step-timing` contains the
expected single commit
- Searched GitHub for duplicate or related open PRs/issues and found no
overlapping open items
- Checked `ROADMAP.md`; the roadmap covers sandboxed environments
generally, but does not call out this specific startup-timing
observability work as a planned duplicate
## Risks
- Low risk: the change is additive and only emits additional structured
events
- If downstream consumers assume startup events are aggregate-only, they
may need to ignore or account for the new `run.startup.step` entries
- Timing is measured via the injected clock and event emission happens
in a `finally`, so failures still report duration before rethrowing

## Thinking Path
> - Paperclip manages agent execution through heartbeat runs and
adapter-specific sessions
> - Plugins can open an agent session and send a conversational message
through the host service
> - The host previously stored that message only in opaque wake payload
metadata, so local adapters never saw it in their CLI prompt
> - The host also forwarded run log chunks but did not expose the
persisted final assistant text as the session reply
> - This pull request defines both sides of the session contract in the
shared wake renderer and terminal run event
> - The benefit is that local adapters receive the actual conversational
turn and plugins receive one canonical final reply
## Linked Issues or Issue Description
Related context: Refs #629 and Refs #2880 describe adjacent
`claude_local` final-text visibility failures. They concern issue
comments rather than plugin agent sessions, but exercise the same need
for a canonical persisted run summary.
Companion consumer change: paperclipai/paperclip-gateway#3.
Bug description:
- **Observed:** calling the plugin host's
`agents.sessions.sendMessage()` with `prompt: "hello"` woke a
`claude_local` agent, but the generated CLI prompt omitted `hello`. On
completion, the session emitted log chunks and a generic `Run completed`
done event, so callers could not reliably recover the assistant reply.
- **Expected:** the prompt becomes the user-supplied conversational turn
for that agent session, and the successful terminal event carries the
run's canonical final user-facing assistant text.
- **Reproduction:** create a plugin agent session for a local adapter,
call `sendMessage()` with a non-empty prompt, inspect the adapter prompt
and terminal session event.
- **Affected baseline:** `b517b887a` on `master`, local trusted
deployment with plugin host services and `claude_local`; `codex_local`
shared the wake-rendering gap because both use the common Paperclip wake
prompt renderer.
## What Changed
- Added a typed `agentMessage` wake payload rendered by the shared
adapter prompt path used by `claude_local`, `codex_local`, and other
local adapters.
- Labeled session content as user-supplied and explicitly
non-authoritative: it cannot expand authorization, permissions, task
scope, or company boundaries.
- Preserved ordinary heartbeat behavior by omitting the section when no
agent-session message exists.
- Added canonical `finalText` to terminal heartbeat status events from
the already-persisted run summary/result/message.
- Defined successful `AgentSessionEvent.message` as the canonical final
user-facing reply (or `null`) and forwarded it on the terminal `done`
event.
- Added host, wake-renderer, normal-heartbeat, and terminal-reply
regression coverage.
## Verification
- `pnpm exec vitest run packages/adapter-utils/src/server-utils.test.ts
server/src/__tests__/heartbeat-agent-session-message.test.ts
server/src/__tests__/heartbeat-run-status-payload.test.ts
server/src/__tests__/plugin-agent-sessions.test.ts
server/src/__tests__/heartbeat-run-summary.test.ts` — 87 passed.
- `pnpm -r typecheck` — passed across all 31 workspaces.
- `pnpm build` — passed.
- `pnpm test:run` — 2,860 passed, 1 skipped, 3 unrelated failures: two
existing macOS temp-path alias assertions (`/tmp` vs `/private/tmp`) in
workspace branch-containment tests and one reproducible auto-port
runtime-service adoption failure. The same three failures reproduce when
the two files run alone; none touch this change.
- Live Slack verification intentionally remains operator-gated because
it requires rebuilding/restarting the host.
## Risks
- User-controlled chat text now reaches the model prompt, which is an
intentional prompt-injection surface. The renderer labels it as
untrusted conversational content, while the existing plugin/session
company checks and caller authorization remain unchanged.
- `finalText` is added to company-scoped heartbeat status events. It is
derived from the same persisted summary/result/message already used for
run comments; no raw stdout or secrets are added.
- Consumers that ignore the new field remain compatible, and successful
runs without usable final text still emit `message: null`.

## Thinking Path
> - Paperclip coordinates autonomous agent work across isolated
company-scoped sessions
> - The ACP remote lane stages workspaces and managed home state inside
the sandbox so sessions can resume safely
> - If a compatible resume re-staged everything every time, it would
waste work and risk inconsistent session reuse behavior
> - If an incompatible resume reused the wrong staged runtime, it could
cross session boundaries or leak credentials
> - This pull request keeps the session fingerprint as the scoping key
and adds a staged-runtime cache keyed to that fingerprint
> - Compatible resumes now reuse the already staged runtime while
incompatible fingerprints stage fresh
> - The benefit is faster safe resumes without weakening session
isolation or credential separation
## Linked Issues or Issue Description
### Problem or motivation
The ACP remote lane currently needs to preserve safe resume behavior
without repeatedly re-staging work that is already valid for the same
session. The failure mode to avoid is letting one session reuse another
session's staged workspace or credentials.
### Proposed solution
Keep the session fingerprint as the scoping key and add a staged-runtime
cache keyed to that fingerprint. When the fingerprint matches, reuse the
already staged workspace and managed home. When the fingerprint changes,
stage fresh.
### Alternatives considered
- Always restage on resume: safest mechanically, but wastes work and
breaks the compatible-resume optimization.
- Reuse without fingerprint scoping: too risky because it could cross
session boundaries.
### Roadmap alignment
This is a narrow implementation change for the ACP remote lane and does
not duplicate any broader roadmap item I could find in `ROADMAP.md`.
### Additional context
The change preserves the existing session fingerprint contents and codex
auth copy-back cadence while adding tests for compatible reuse,
incompatible fresh staging, no cross-session credential reuse, and
failed-turn eviction.
## What Changed
- Added a staged-runtime cache in the ACP remote execution path keyed by
the session fingerprint.
- Reused the existing staged workspace and managed home for compatible
resumes.
- Kept incompatible fingerprints on the fresh staging path.
- Preserved the existing session fingerprint contents and codex auth
copy-back cadence.
- Added tests for compatible reuse, incompatible fresh staging, no
cross-session credential reuse, and failed-turn eviction.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` (74/74 pass,
including the active-turn lease regression)
- `pnpm exec tsc -p packages/adapter-utils/tsconfig.json --noEmit`
- Verified the PR touches only
`packages/adapter-utils/src/acpx-engine/execute.ts` and
`packages/adapter-utils/src/acpx-engine/execute.test.ts`
## Risks
- A cache eviction bug could cause an unavailable or partially staged
runtime to be reused.
- If the fingerprint scoping regressed, a session could incorrectly
reuse another session's state.
- The change is isolated to the ACP remote lane, but it still affects
resume behavior for that path.
## Model Used
OpenAI Codex, GPT-5, reasoning-capable coding agent, tool-enabled
session.

## Thinking Path
> - Paperclip is a control plane that orchestrates AI agents and adapter
execution for human operators.
> - Agents run across local and remote execution contexts, and
reliability in remote sessions depends on consistent adapter
bootstrapping.
> - The ACP path must prepare per-adapter runtime homes so managed
credentials and config are available in sandboxed runner environments.
> - Before this change, the new remote ACP lane did not yet consistently
stage managed-home paths for all affected adapters or restore Codex auth
state on teardown.
> - We added a shared per-adapter seam in the ACP engine, then wired
Codex, Claude, and Gemini remote lanes to seed managed homes and remap
to in-sandbox locations.
> - Codex additionally reuses the existing atomic auth restore flow to
copy auth back on teardown, matching CLI behavior.
> - This improves remote runner parity with existing CLI behavior and
avoids credential drift in shared-code-path executions.
## Linked Issues or Issue Description
- This change continues the ACP remote managed-home work by completing
per-adapter remote bootstrapping and Codex auth restore behavior for the
remote ACP lane.
- It specifically covers: `acpx-engine`, `codex-local`, `claude-local`,
and `gemini-local`.
- Related prior work in this repo: PR #10070.
## What Changed
- Add a per-adapter remote managed-home seam
(`prepareRemoteManagedHome`) in `acpx-engine` and thread it through ACP
execution options.
- Implement Codex ACP preparation to:
- stage `CODEX_HOME` (auth/config/skills) into a sandboxed remote home,
- repoint `CODEX_HOME` to the in-sandbox path,
- and wire teardown copy-back through the existing managed-auth restore
path.
- Implement Claude ACP preparation to seed a sanitized `config-seed`
into `CLAUDE_CONFIG_DIR` and remap that directory to the sandbox root.
- Implement Gemini ACP preparation to seed `~/.gemini/skills`, set
`HOME` to managed runtime root, and preselect API-key auth in
`settings.json`.
- Keep local and runner-less ACP→CLI behavior unchanged by only invoking
the remote managed-home seam when running in remote ACP mode.
- Preserve existing authorization and activity boundaries in the shared
engine and adapter layers.
## Verification
- `git log --oneline
origin/master..origin/feat/acp-remote-managed-home-seed` confirms only
the expected 4 commits.
- `tsc --noEmit` is clean in `adapter-utils`, `codex-local`,
`claude-local`, and `gemini-local`.
- Vitest selection used during validation passed (120 tests across the
ACP-related suites).
## Risks
- If remote sandbox teardown occurs after token rotation but before
restore timing, Codex credentials can become stale and require re-auth
on next startup.
- Partial provisioning of managed-home assets would cause adapter
bootstrap failures in runner-backed ACP sessions.
- This change is scoped to execution-path behavior; it should not affect
CLI behavior.
## Model Used
None — human-authored.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The shared ACP engine
(`packages/adapter-utils/src/acpx-engine/execute.ts`) is responsible for
launching local and remote agent processes via the ACP protocol
> - On runner-backed remote sandbox (Daytona) targets, `buildRuntime`
never crossed the CLI's staging seam: it never called
`prepareAdapterExecutionTargetRuntime`, left `runtimeRootDir: null` in
both the paperclip and process-session bridges, and handed the agent the
**HOST filesystem path** as the `session/new` cwd — meaning
Claude/Gemini silently operated on a path that does not exist inside the
sandbox (Codex additionally crashes on its HOST home path, addressed in
a follow-up PR)
> - The fix must cross the staging seam for remote sandboxes, thread the
real `runtimeRootDir` through both bridges, and bind the in-sandbox
workspace path as the session cwd — without touching local ACP runs or
the runner-less ACP→CLI fallback
> - This pull request introduces a `stageAcpRemoteRuntime` helper that
calls `prepareAdapterExecutionTargetRuntime` for runner-backed remote
runs, captures `{ workspaceRemoteDir, runtimeRootDir, assetDirs,
restoreWorkspace }`, and reuses the in-sandbox `workspaceRemoteDir` as
the single `sessionCwd` across `session/new`, the fingerprint,
compatibility check, persistence, `ensureSession`, the process-session
bridge cwd, and the error path
> - The benefit is that remote ACP runs now operate in the correct
in-sandbox cwd and receive a non-null `runtimeRootDir` in both bridges —
fixing silent wrong-cwd degradation for Claude/Gemini on Daytona
targets; this is PR 1 of 3 and seeds no credential material
## Linked Issues or Issue Description
No public GitHub issue exists for this change. Inline description
follows the feature request template:
### Subsystem affected
packages/adapters — agent adapter implementations
### Problem or motivation
The shared ACP engine
(`packages/adapter-utils/src/acpx-engine/execute.ts`) never crossed the
CLI's staging seam on runner-backed remote sandbox targets. It never
called `prepareAdapterExecutionTargetRuntime`, always passed
`runtimeRootDir: null` to both the paperclip and process-session
bridges, and handed the agent the **HOST filesystem path** as the ACP
`session/new` cwd. As a result, Claude and Gemini silently operated on a
cwd that does not exist inside the sandbox; Codex crashed with a fatal
error on the HOST `CODEX_HOME` path (that crash is in a follow-up PR).
### Proposed solution
Gate on `usesRunnerBackedSandbox` (`kind === "remote" && transport ===
"sandbox" && runner`). For runs that pass the gate, call
`prepareAdapterExecutionTargetRuntime` via a new `stageAcpRemoteRuntime`
helper that ships the workspace into the sandbox and captures `{
workspaceRemoteDir, runtimeRootDir, assetDirs, restoreWorkspace }`.
Thread the real `runtimeRootDir` into both bridges. Bind a single
`sessionCwd` (the in-sandbox `workspaceRemoteDir`) and use it at every
cwd-keyed session site (`session/new`, fingerprint, compat, persist,
`ensureSession`, process-session bridge, error path) so a warm/resumable
session is reused rather than invalidated. For local runs and the
runner-less ACP→CLI fallback, `sessionCwd` resolves to the HOST cwd —
byte-identical to the previous behavior.
### Alternatives considered
Patching each per-adapter bridge individually — rejected because the bug
is in the shared engine layer and the fix belongs there so all three
adapters (Codex, Claude, Gemini) benefit without per-adapter
duplication.
### Roadmap alignment
Internal correctness fix enabling remote ACP to work as designed; no new
user-facing features. This is PR 1 of 3 in a sequential chain: PR 1
(this PR) stages the workspace and routes the cwd; PR 2 adds per-adapter
home seeding and copy-back; PR 3 wires session-lifecycle restore.
## What Changed
- **`packages/adapter-utils/src/acpx-engine/execute.ts`** — added
`stageAcpRemoteRuntime` helper that calls
`prepareAdapterExecutionTargetRuntime` for runner-backed remote
sandboxes and returns `{ sessionCwd, runtimeRootDir, stagedRuntime }`;
`buildRuntime` now uses this helper to derive `sessionCwd` (in-sandbox
`workspaceRemoteDir` for remote; HOST cwd unchanged for
local/runner-less) and threads the real `runtimeRootDir` to both the
paperclip bridge and process-session bridge; `stagedRuntime` is stashed
for the follow-up credential PR
- **`packages/adapter-utils/src/acpx-engine/execute.test.ts`** — new
engine-level unit tests: staging seam crossed with no credential asset,
non-null `runtimeRootDir` in both bridges, in-sandbox `session/new` cwd,
warm-handle reuse after the cwd change, local-unchanged; 60 tests green
- **`packages/adapters/codex-local/src/server/acp.test.ts`** — new
per-adapter test: runner-backed remote asserts `ensureSession` cwd ==
`workspaceRemoteDir`; runner-less sandbox falls back to CLI
- **`packages/adapters/claude-local/src/server/acp.test.ts`** — same
per-adapter coverage for Claude
- **`packages/adapters/gemini-local/src/server/acp.test.ts`** — same
per-adapter coverage for Gemini
## Verification
- `adapter-utils` typecheck clean; `codex/claude/gemini-local` typecheck
clean
- Engine units (`acpx-engine/execute.test.ts`): 60/60 green — staging
seam crossed with no credential asset, non-null `runtimeRootDir` to both
bridges, in-sandbox `session/new` cwd, warm-handle reuse after cwd
change, local unchanged
- Per-adapter ACP test suites (`codex/claude/gemini-local`
`acp.test.ts`): 103 tests green — runner-backed remote asserts
`ensureSession` cwd == `workspaceRemoteDir`; runner-less sandbox falls
back to CLI
- CI green on PR (in progress)
## Risks
This is PR 1 of 3 in a strictly sequential chain; it seeds **no
credential material** (no `assets`, no `installCommand`). The
per-adapter home seeding is deferred to PR 2, which consumes the
`stagedRuntime` object stashed here. The `restoreWorkspace` callback is
carried on `stagedRuntime` for PR 3's session-lifecycle wiring (see the
`stageAcpRemoteRuntime` function comment). Local ACP runs and the
runner-less ACP→CLI fallback are untouched — `sessionCwd` resolves to
the HOST cwd for those paths, preserving existing behavior. The
`stageAcpRemoteRuntime` helper is gated on `usesRunnerBackedSandbox`, so
there is no regression risk for local or CLI-lane runs.

## Thinking Path
> - Paperclip is an open-source AI-agent management platform; agents run
tasks inside sandboxed environments (Daytona, Kubernetes, E2B, etc.)
> - The control-plane ↔ sandbox file-transfer path flows through the
`environmentExecute` seam in `protocol.ts` — the only verb available to
plugins — which forces a base64-over-exec chunked loop for every file
move: workspace files, assets, Codex home sync
> - This transport is correct and safe, but it bypasses provider-native
bulk/streaming APIs (Daytona `uploadFiles`, K8s `FastUploadInterceptor`
/ volume mounts), leaving significant throughput on the table for large
workspaces
> - The right fix is an opt-in seam extension: providers with faster
native transfer declare two optional verbs; providers that do not opt in
stay on the existing fallback with zero code or behavior change required
> - This PR adds the first layer of that extension — two optional verbs
(`environmentSyncIn` / `environmentSyncOut`) in the plugin SDK, the
runtime plumbing to prefer the native path for the two clean
destroy-then-replace cases, and a doc for the contract
> - The core correctness invariant is byte-identical fallback: if no
provider opts in, execution is exactly what ships today;
`assertSyncOperationsConfined` enforces host-side path confinement for
providers that do opt in
> - No provider advertises the verbs yet → zero production behavior
change; future PRs wire up Daytona and K8s providers against this
contract
## Linked Issues or Issue Description
No public GitHub issue exists for this feature. Description follows the
`feature_request` issue template:
**Subsystem affected:**
packages/plugins — plugin system; packages/adapter-utils — adapter
runtime; server/ — EnvironmentRuntimeService
**Problem or motivation:**
Sandbox file transfers currently always use a base64-over-exec chunked
loop regardless of what the underlying provider supports. For workspaces
larger than a few MB this becomes the dominant wall-clock cost of every
sandbox run, and it bypasses bulk/stream APIs that providers like
Daytona already expose natively.
**Proposed solution:**
Add two optional, opt-in plugin hooks — `onEnvironmentSyncIn` /
`onEnvironmentSyncOut` — to the plugin SDK. When a provider defines both
hooks and both are advertised via the existing `supportedMethods`
negotiation, the runtime prefers the native path for the two clean
destroy-then-replace transfer cases; all other cases fall back to the
existing byte-identical base64 transport.
**Alternatives considered:**
An unconditional verb would require every provider to implement or stub
the verb. The opt-in / `METHOD_NOT_IMPLEMENTED` pattern (already used by
`environmentExecute`) preserves backward compatibility with zero
provider changes required.
**Roadmap alignment:**
Consistent with the ✅ "Cloud / Sandbox agents" and ✅ "Plugin system"
milestones; extends the plugin seam rather than adding
control-plane-level logic.
**Additional context:**
Searched open pull requests and issues for duplicate sandbox file-sync /
native-transfer work; none found.
## What Changed
- **`packages/plugins/sdk`**
- `protocol.ts`: two new optional `HostToWorkerMethods` —
`environmentSyncIn` / `environmentSyncOut` — plus generic
`SyncOperation`, `SyncFileMapping`, and `SyncOutcome` types
- `define-plugin.ts`: optional `onEnvironmentSyncIn` /
`onEnvironmentSyncOut` fields on `PluginDefinition`; worker advertises
each verb only when its hook is defined (else `METHOD_NOT_IMPLEMENTED`,
mirroring `environmentExecute`)
- `worker-rpc-host.ts`: route new verbs to plugin hooks
- `index.ts`: re-export new public types
- **`packages/adapter-utils`**
- `command-managed-runtime.ts`: expose optional `syncIn` / `syncOut` on
`CommandManagedRuntimeRunner` (available only when both verbs are
advertised); add `assertSyncOperationsConfined` host-side
path-confinement guard
- `sandbox-managed-runtime.ts`: `SandboxManagedRuntimeClient` gains
optional `syncIn` / `syncOut`; orchestrator prefers native path for
default-provision asset inbound and workspace-download-into-fresh-dir
outbound; all other paths keep the existing base64 fallback
- `sandbox-file-sync.test.ts` (new): 234-line characterization suite —
native-opt-in branch, fallback branch, `assertSyncOperationsConfined`
escape-path rejection, `followSymlinks` → tar `-h`
- `command-managed-runtime.test.ts`: negotiation + native-sync +
confinement tests
- **`server/src/services/environment-runtime.ts`**:
`EnvironmentRuntimeService` delegates to `syncIn` / `syncOut`, gated on
advertised support
- **`server/src/services/environment-execution-target.ts`**: minor
typing fix alongside the new verbs
- **`doc/plugins/SANDBOX_FILE_SYNC_HOOKS.md`** (new): documents the full
contract — opt-in / no-op guarantee, operation ordering,
provider-may-tar, atomicity, `followSymlinks`, secret modes (0600, no
window), path confinement, `operationId` opacity, resource bounds,
shell-quoting
## Verification
```bash
# SDK suite
pnpm --filter packages/plugins/sdk test
# Adapter-utils suite (includes new sandbox-file-sync characterization tests)
pnpm --filter packages/adapter-utils test
# Expected: 255 pass / 4 skip
# Type-check across affected packages
pnpm --filter packages/plugins/sdk typecheck
pnpm --filter packages/adapter-utils typecheck
# Server changed-file spot check:
cd server && npx tsc --noEmit --skipLibCheck 2>&1 | grep -E "environment-(runtime|execution-target)" | head -20
```
Key behavioral invariant to spot-check: with no provider opting in (the
current state), run any sandbox task and confirm file-transfer behavior
is byte-for-byte identical to what the pre-PR code produces. The
characterization tests assert this at the unit level.
## Risks
- **Zero production risk today**: no provider advertises
`environmentSyncIn` / `environmentSyncOut`, so the new code paths are
unreachable in production; all real traffic stays on the existing base64
fallback
- **Path confinement**: `assertSyncOperationsConfined` rejects any
`targetPath` that escapes the declared root — this is the primary
security boundary for future providers. The test suite covers
escape-path rejection
- **Atomicity**: the contract delegates atomicity to providers; the doc
explicitly calls out that directory-level ops are not guaranteed atomic
- **Secret transport**: credential assets (e.g., Codex `auth.json`,
directory mappings) continue to use the existing tar path — they do not
go through the new verbs in any current provider

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local Claude, Codex, Gemini, and custom ACP adapters run through the
shared embedded ACPX engine
> - That engine wrapped every local agent command in a generated Bash
script to inject environment variables and filter child stderr
> - Windows cannot directly spawn that Bash wrapper, and npm/pnpm ACP
binaries are exposed through `.cmd` shims there
> - ACPX 0.12 already supports per-session child environment variables,
so the wrapper is unnecessary
> - This pull request registers agent commands directly, injects env
through ACPX session options, captures child stderr in-process, and adds
a real Node ACP spawn smoke on Ubuntu and Windows
> - The benefit is one cross-platform spawn path with a reusable smoke
test instead of parallel shell-wrapper implementations
## Linked Issues or Issue Description
Fixes#9941.
Refs #9428 and #9771.
**What happened**
ACPX-backed local agents failed to start on Windows because Paperclip
registered a generated POSIX `.sh` wrapper as the agent command. Windows
also needs the `.cmd` npm/pnpm shim when resolving built-in ACP
binaries, and symlink creation can fail with `EPERM` for seeded
auth/skill files.
**Expected behavior**
The same ACPX engine path should spawn a real ACP agent on Windows and
Linux, forward Paperclip/runtime env without mutating `process.env`,
preserve filtered/unfiltered child stderr behavior, and fall back to
copies where Windows symlinks are unavailable.
**Steps to reproduce**
Run a local ACPX adapter on Windows with the prior wrapper path. ACPX
attempts to spawn the generated `.sh` file and the agent never
initializes.
**Deployment mode**
Local Paperclip adapters using
`packages/adapter-utils/src/acpx-engine/`.
## What Changed
- Removed generated Bash agent/env wrappers and registered local
commands directly with ACPX.
- Passed the resolved child environment through ACPX
`sessionOptions.env`, including resume retry paths.
- Added a minimal `acpx@0.12.0` package patch exposing child stderr
callbacks and allowing documented uppercase env-map keys in persisted
session options.
- Moved stderr tee/filter behavior in-process: raw stderr remains in the
per-run file while benign `nes/close` noise is omitted from live stderr.
- Preferred `.cmd` ancestor binaries on Windows and added `EPERM` copy
fallbacks for Codex auth seeding and Gemini skill materialization.
- Added a real Node ACP echo-agent spawn smoke that can run directly on
any supported platform.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts
packages/adapter-utils/src/acpx-engine/spawn-smoke.test.ts` — 57 passed.
- `pnpm --filter @paperclipai/adapter-utils typecheck` — passed.
- `node --test scripts/acpx-patch-packaging.test.mjs
scripts/release-lib.test.mjs` — 10 passed.
- Full canary release dry run under Node 24.18.0 / npm 11.16.0 — passed
in an isolated scratch clone.
- `git diff --check` — passed during implementation verification.
- One-time GitHub Actions proof: [Ubuntu ACPX spawn
smoke](https://github.com/paperclipai/paperclip/actions/runs/29924348927/job/88937774579),
[Windows ACPX spawn
smoke](https://github.com/paperclipai/paperclip/actions/runs/29924348927/job/88937774558),
and [Canary Dry
Run](https://github.com/paperclipai/paperclip/actions/runs/29924348927/job/88937774497)
passed on head `f345ac69f2`; the dedicated smoke jobs are intentionally
not retained in the recurring PR workflow.
## Risks
- The ACPX stderr callback and env persistence exemption are carried as
a pnpm dependency patch until ACPX exposes/fixes those behaviors
upstream.
- Child stderr is synchronously appended to preserve ordering and
failure diagnostics; unusually high-volume agent stderr could briefly
block the Node event loop.
- The Windows-specific `.cmd` resolution and symlink `EPERM` branches
are proven by the standalone smoke test and the linked one-time
`windows-latest` run rather than a permanent CI gate.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent runs get their environment from user/adapter/project/routine
env bindings resolved by the server heartbeat, plus `PAPERCLIP_*`
runtime vars (identity, wake, workspace, API access) injected by the
harness
> - The heartbeat stripped **every** `PAPERCLIP_`-prefixed binding
before resolution, so legitimately user-named keys (e.g. cloud provider
token bindings like `PAPERCLIP_CLOUD_PROD_PROVIDER_RAILWAY_*`) were
silently dropped and never reached the run env
> - At the same time, several adapters honored an explicitly configured
`PAPERCLIP_API_KEY` over the harness-minted run token, which is exactly
the one key config must never control
> - This pull request replaces the blanket prefix strip with a precise
three-rule policy: never accept `PAPERCLIP_API_KEY` from config, always
let harness-assigned runtime vars win, and let every other
`PAPERCLIP_*`-named user binding flow through
> - The benefit is that user secrets with a `PAPERCLIP_`-style name work
like any other binding, while runtime identity and API credentials stay
fully harness-controlled
## Linked Issues or Issue Description
**Bug description** (no public issue exists):
- **What happened:** Env bindings whose key starts with `PAPERCLIP_`
(e.g. a cloud provider token a user deliberately named
`PAPERCLIP_CLOUD_PROD_PROVIDER_RAILWAY_TOKEN`) were silently stripped by
the server before secret resolution, so the spawned agent never received
them. No error, no access event — the variable just never appeared.
- **Expected behavior:** A user-named `PAPERCLIP_*` binding should reach
the run env unless the harness itself uses that key. Only
`PAPERCLIP_API_KEY` should be categorically rejected, and
harness-assigned runtime vars (`PAPERCLIP_RUN_ID`, `PAPERCLIP_AGENT_ID`,
wake/workspace vars, …) should always win over config.
- **Steps to reproduce:** Configure an agent/project env binding named
`PAPERCLIP_<ANYTHING>` (plain or secret_ref), run a heartbeat, and
inspect the spawned process env — the key is absent.
- **Deployment mode:** local server, any local adapter.
Related prior PRs (different, save-time/API-layer blanket-ban approach;
this PR supersedes that direction with a runtime allow-except-reserved
policy): Refs #8239, Refs #8439.
## What Changed
- `server/src/services/heartbeat.ts`: the pre-resolution strip now
removes only `PAPERCLIP_API_KEY` (hard denylist) instead of every
`PAPERCLIP_`-prefixed binding; other `PAPERCLIP_*` keys flow into
binding resolution. Low-trust inline-sensitive-env checks now also cover
those keys.
- `packages/adapter-utils/src/server-utils.ts`: new
`isForbiddenConfigEnvKey()` helper; the shared
`refreshPaperclipWorkspaceEnvForExecution` merge drops
`PAPERCLIP_API_KEY` from config and keeps harness-assigned `PAPERCLIP_*`
keys authoritative.
- `packages/adapter-utils/src/acpx-engine/execute.ts`: removed the
explicit-`PAPERCLIP_API_KEY`-from-config allowance; the run token
(`authToken`) is now always applied; config `PAPERCLIP_API_KEY` is
ignored.
- All local adapters (`claude-local`, `codex-local`, `cursor-local`,
`gemini-local`, `grok-local`, `opencode-local`, `pi-local`) plus
`cursor-cloud`, `hermes`, and the server `process` adapter: removed
`hasExplicitApiKey`-style allowances so the harness token always wins,
and guarded the remaining unguarded env-merge loops (claude-local inline
loop, process adapter) with the same policy.
- Tests updated/added: heartbeat binding-strip test now asserts the
three-rule policy; adapter-utils merge tests assert the
`PAPERCLIP_API_KEY` ban and `PAPERCLIP_*` pass-through; acpx engine
tests moved credential fixtures to `authToken` and assert config
`PAPERCLIP_API_KEY` is ignored while other `PAPERCLIP_*` config keys
forward and still bust the session fingerprint on rotation.
## Verification
- `pnpm vitest run packages/adapter-utils/src/server-utils.test.ts
packages/adapter-utils/src/acpx-engine/execute.test.ts` — 127 passed
- `pnpm vitest run server/src/__tests__/heartbeat-project-env.test.ts
server/src/__tests__/heartbeat-local-environment.test.ts
server/src/__tests__/claude-local-execute.test.ts
server/src/__tests__/codex-local-execute.test.ts
server/src/__tests__/cursor-local-execute.test.ts
server/src/__tests__/gemini-local-execute.test.ts` — 68 passed
- Adapter package execute suites and the server tests touching API-key
fixtures (`heartbeat-run-log`, `redaction`,
`effective-run-config-fingerprints`, `agent-permissions-routes`) —
green. Three pre-existing sandbox/SSH fixture failures reproduce
identically on clean `master` on this host and are unrelated.
- `pnpm --filter <pkg> typecheck` for server, adapter-utils, and all
nine touched adapter packages — all pass.
## Risks
- Behavioral change: a deployment that relied on configuring a static
`PAPERCLIP_API_KEY` in adapter config env loses that override — by
design; the harness-minted run token is now the only source. When no run
token exists, no API key is injected at all.
- `PAPERCLIP_*`-named user bindings now reach binding resolution and run
envs; a key that collides with a harness runtime var is still discarded
at merge time, so runtime identity/wake/workspace vars cannot be
spoofed.
- Low risk otherwise: no migrations, no API surface changes.
## Model Used
- Claude Fable 5 (`claude-fable-5`, Anthropic Claude 5 family,
Mythos-class tier), extended thinking enabled, agentic tool use (file
edits, shell, test runner) via Claude Agent SDK.

## Thinking Path
> - Paperclip is an open source platform for managing AI agent teams,
with adapter packages providing concrete runtime environments (e.g.
`codex-local` runs a local OpenAI Codex sandbox)
> - `adapter-utils` is the shared utilities package — it should hold
only generic, adapter-agnostic primitives (sandbox lifecycle helpers,
merge logic, type definitions) usable by every adapter
> - Three files lived in `adapter-utils/src/` that are entirely
Codex-specific: `codex-auth-merge-extract.sh` (shell script that
extracts auth tokens), `codex-auth-merge-decision.cjs` (CJS decision
helper), and `codex-auth-merge-scripts.ts` (TypeScript factory that
wires them into the inbound provision seam added in PR #9778)
> - Their presence in a "generic" package violates the adapter isolation
principle and requires a cross-package build step to copy `.sh`/`.cjs`
files into `codex-local/dist/server/` at build time
> - This PR completes Phase 2 of the inbound-seam refactor: move all
three files to `packages/adapters/codex-local/src/server/`, rebase the
TypeScript imports, update `execute.ts` to import locally, move the
Codex-auth tests into a new `codex-local` test file, and fix packaging
so `codex-local` copies its own scripts to `dist/server/`
> - Script bytes are identical after the move; no change to inbound
auth-merge behavior or to which bytes cross the sandbox boundary
> - The benefit is a clean ownership boundary: `adapter-utils` retains
only generic runtime code, and the structural "Codex-free core" test in
the adapter-utils suite validates this invariant going forward
## Linked Issues or Issue Description
No pre-existing public GitHub issue. Describing the underlying problem
inline:
**Problem:** `packages/adapter-utils/src/` contains three files
(`codex-auth-merge-extract.sh`, `codex-auth-merge-decision.cjs`,
`codex-auth-merge-scripts.ts`) consumed exclusively by the `codex-local`
adapter. Their presence in a generic utilities package violates adapter
isolation and requires a cross-package build step (copy `.sh`/`.cjs`
into `codex-local/dist/server/`). The inbound provision seam landed in
PR #9778 routed these through `adapter-utils`; this PR finishes the
relocation.
**Related:** Refs #9778 (Phase 1 — generic asset-lifecycle-seam, now
merged).
## What Changed
- Moved `codex-auth-merge-extract.sh`, `codex-auth-merge-decision.cjs`,
and `codex-auth-merge-scripts.ts` from `packages/adapter-utils/src/` →
`packages/adapters/codex-local/src/server/` (script bytes are unchanged;
`codex-auth-merge-scripts.ts` imports rebased to `adapter-utils`
subpaths for `shellQuote` and `SandboxManagedRuntimeAssetProvision`)
- `packages/adapters/codex-local/src/server/execute.ts`: updated import
of `buildCodexAuthInboundProvision` from `adapter-utils` → local
`./codex-auth-merge-scripts`
- New
`packages/adapters/codex-local/src/server/codex-auth-merge.test.ts` — 5
Codex-auth test rows extracted from
`adapter-utils/src/workspace-restore-merge.test.ts`; the generic test
file stays and no longer references Codex
- `packages/adapters/codex-local/package.json`: build now copies
`.sh`/`.cjs` from `src/server/` into `dist/server/` directly
- `packages/adapter-utils/package.json`: removed the now-obsolete
cross-package copy step for those files
## Verification
```sh
# Type-check both affected packages
pnpm --filter @paperclipai/adapter-utils --filter @paperclipai/adapter-codex-local typecheck
# Codex auth-merge suite (moved tests — 5/5 pass)
pnpm --filter @paperclipai/adapter-codex-local test -- --reporter=verbose codex-auth-merge
# Full adapter-utils suite including the structural "core free of Codex literals" test (243 passed, 4 pre-existing skips)
pnpm --filter @paperclipai/adapter-utils test
# Confirm build copies scripts to dist/server
pnpm --filter @paperclipai/adapter-codex-local build
ls packages/adapters/codex-local/dist/server/*.sh packages/adapters/codex-local/dist/server/*.cjs
```
All of the above were run locally and passed before this PR was opened.
## Risks
Low risk — pure file relocation:
- No change to `.sh` or `.cjs` script bytes; the same content reaches
the sandbox boundary as before
- No behavioral change to inbound auth-merge logic from the sandbox's
perspective
- `adapter-utils`' structural "core free of Codex literals" test now
validates that the relocation is complete and will catch any regression
- Only `codex-local` consumed these files from `adapter-utils`; no other
package in the monorepo imported them from there

## Thinking Path
> - Paperclip's sandbox managed runtime is responsible for provisioning
the agent's execution environment — it extracts a home directory asset
into the sandbox before the adapter runs.
> - The sandbox runtime core was directly branching on the adapter key
(`codex`) to decide which merge scripts to stage and which merge-extract
command to run, coupling generic infrastructure to a specific adapter's
credential-merge protocol.
> - This makes it harder to add, remove, or modify per-adapter asset
provisioning without touching the runtime core; it also prevents other
adapters from contributing staged files or a custom extract command at
all.
> - The fix is to move the adapter-specific knowledge into the adapter
itself: the asset descriptor gains optional `provision` (stageFiles +
extractCommand) and `restore` contribution fields that any adapter can
populate, and the runtime core consumes them generically.
> - This pull request introduces those contribution fields, wires the
Codex adapter's inbound credential-merge as a `provision` contribution,
and removes the adapter-specific branching from the runtime core.
> - The benefit is a clean seam: the runtime core is now
adapter-agnostic for asset provisioning, the inbound behavior is
unchanged (same merge matrix, same scripts), and other adapters can
attach custom staged files or extract commands without modifying shared
infrastructure.
## Linked Issues or Issue Description
No pre-existing public GitHub issue. Describing the problem inline per
the feature template:
**Problem or motivation**
The sandbox managed-runtime asset provisioning in
`sandbox-managed-runtime.ts` branched directly on the adapter key
(`codex`) to decide which merge scripts to stage and which shell command
to use during asset extraction. This tight coupling prevents other
adapters from customizing their provisioning without modifying the
runtime core, and it means the runtime core must import and know about
adapter-specific merge scripts.
**Proposed solution**
Add an optional `provision` contribution (array of `stageFiles` entries
+ an `extractCommand` string) and an optional `restore` contribution to
the asset descriptor returned by adapters. The runtime core now consumes
these generically — if a `provision` contribution is present, it stages
those files and uses the supplied command; otherwise it falls back to
the default `tar -xf` extraction. The Codex adapter populates the
`provision` contribution where it previously depended on core branching.
**Alternatives considered**
Keeping the adapter-specific logic in the core as a documented
exception; rejected because it makes the seam inextensible.
**Roadmap alignment**
Decoupling — removes a latent coupling between the runtime core and a
specific adapter.
## What Changed
- Added `provision` contribution field (`stageFiles: Array<{src, dest}>`
+ `extractCommand: string`) to the `SandboxManagedRuntimeAsset`
descriptor type in `adapter-utils`.
- Added `restore` contribution field (hook for post-restore logic,
populated in a later phase) to the descriptor.
- Removed adapter-key branching (`if adapterKey === 'codex'`) from the
runtime core in `sandbox-managed-runtime.ts`; the core now reads
`provision.stageFiles` and `provision.extractCommand` generically.
- Extracted Codex-specific merge-script paths and the merge-extract
command into `codex-auth-merge-scripts.ts` in `adapter-utils`; the Codex
adapter's `execute.ts` now attaches them as a `provision` contribution
when it builds its managed-home asset descriptor.
- Updated `execution-target.ts` to pass the extended asset type through
to the adapter call site so the new fields are load-bearing end-to-end.
- Added seam-proving unit tests in `sandbox-managed-runtime.test.ts`:
contribution-less asset uses the default path; a non-adapter asset
round-trips the generic provision+restore seam; a structural assertion
verifies the runtime core carries no Codex-specific string literals.
- Added one test in `workspace-restore-merge.test.ts` confirming the
inbound merge matrix is unaffected.
## Verification
```bash
# Unit tests (20 pass):
npx vitest run packages/adapter-utils/src/sandbox-managed-runtime.test.ts packages/adapter-utils/src/workspace-restore-merge.test.ts
# Type-check both affected packages:
cd packages/adapter-utils && npx tsc --noEmit
cd packages/adapters/codex-local && npx tsc --noEmit
# Structural: runtime core carries no adapter string literals
grep -n 'codex\|auth\.json' packages/adapter-utils/src/sandbox-managed-runtime.ts
# Expected: zero matches
```
## Risks
**Low risk.** This is a behavior-preserving refactor: the inbound
provisioning output (which files get staged, which command runs) is
identical to before, now driven by the adapter-supplied contribution
instead of core branching. The existing inbound merge matrix tests are
the regression guard. No change to which bytes cross the sandbox
boundary. The SSH transport is untouched.

## Thinking Path
> - Paperclip is the open source control plane people use to coordinate
AI-agent companies and their work.
> - Its recovery subsystem detects stranded issue execution and decides
whether to retry, escalate, or request operator intervention.
> - The existing recovery path used a mostly generic owner ladder and
generic execution contract, so transient failures could wake a manager
who then performed the deliverable instead of repairing and returning
the task.
> - Provider quota failures also entered the same takeover path even
when the correct action was to wait for capacity and retry the original
assignee.
> - Recovery actions already retain the source owner and evidence needed
to choose a cause-specific route, render a scoped contract, and measure
whether work was handed back.
> - This pull request adds a cause-keyed recovery playbook, propagates
its contract through every built-in adapter, and makes resolved recovery
actions return work to the original owner by default.
> - The benefit is bounded self-recovery that preserves task ownership,
avoids needless management takeover, and makes recovery outcomes
observable.
## Linked Issues or Issue Description
No matching public GitHub issue was found.
Related recovery work was reviewed but is not duplicated here: #9630
restores bounded recovery continuations, #8807 changes one
assignee-ranking case, and #9404 records runtime-failure transition
evidence. This change instead introduces cause-specific routing and
recovery contracts across the recovery lifecycle.
### What happened?
When an issue became stranded, recovery generally selected an owner
through the same fallback ladder and rendered the normal execution
contract. That made the recovery wake look like ordinary deliverable
work, even when the correct action was to retry the original agent,
repair its runtime, or wait for a provider quota reset.
### Expected behavior
Recovery should select a response by failure cause, tell the recipient
to recover rather than complete the deliverable, suppress takeover wakes
for provider quota waits, and return repaired work to its original
assignee unless the recovery owner explicitly completes it.
### Actual behavior
Recovery could escalate transient failures to management, omit the
cause-specific next action from the wake, and leave the recovery owner
assigned after the runtime problem was resolved.
### Impact
The generic path creates avoidable management work, ownership churn, and
budget consumption while obscuring whether recovery successfully
returned work to the responsible agent.
## What Changed
- Added cause-keyed routing for process loss, missing disposition,
provider quota limits, Codex output inactivity, workspace validation
failures, and fallback recovery causes.
- Added recovery-scoped wake rendering that replaces the generic
execution contract with the failure summary, original assignee, attempt
count, next action, and cause-specific playbook instruction.
- Propagated the structured recovery contract through all built-in
adapter execution paths, including Hermes local and gateway adapters.
- Added provider-quota wait monitoring so capacity failures schedule the
original assignee instead of enqueueing a takeover wake.
- Added hand-back behavior and `handed_back` / `owner_completed` outcome
accounting when recovery actions are resolved.
- Added focused routing, renderer, quota-monitor, and hand-back
regression coverage plus implementation-spec documentation.
## Verification
- `pnpm exec vitest run packages/adapter-utils/src/server-utils.test.ts
server/src/__tests__/heartbeat-process-recovery.test.ts
server/src/__tests__/heartbeat-workspace-branch-containment.test.ts
server/src/__tests__/issue-recovery-actions.test.ts`
- 4 test files passed; 194 tests passed.
- Targeted `pnpm --filter ... typecheck` across
`@paperclipai/adapter-utils`, `@paperclipai/shared`,
`@paperclipai/server`, `@paperclipai/ui`, and all nine changed adapter
packages.
- 13 affected workspace packages passed typecheck.
- `pnpm check:token-gates`
- All UI token gates passed.
## Risks
- Recovery routing behavior changes for stranded work, so an incorrectly
classified cause could select a different recipient than before;
fallback causes retain the existing management ladder.
- Provider quota detection depends on structured failure evidence and
conservative text matching; unmatched failures continue through fallback
recovery.
- Adapter prompt plumbing changes across built-ins, covered by shared
renderer tests and compile-time call signatures.

## Thinking Path
> - Paperclip is the open source control plane people use to manage
AI-agent companies.
> - Company skills make reusable agent behavior discoverable and
editable from one place.
> - Projects already contain skill directories, but operators had to
import each skill path manually.
> - Copying those skills would break the desired write-through workflow
between Skill Studio and the source project.
> - The server therefore needs a safe preview/select/import contract
that only accepts rediscovered, workspace-contained candidates.
> - The UI needs a guided project picker that explains reference
semantics, handles conflicts, and remains usable on mobile.
> - This pull request adds that end-to-end project skill import flow
with authorization, tenant-scope, traversal, and symlink regression
coverage.
> - The benefit is faster bulk onboarding while keeping project files as
the single source of truth.
## Linked Issues or Issue Description
**Feature request**
**Problem:** Importing several skills already stored in a Paperclip
project requires operators to discover and submit each local path
individually. This is slow, hides which well-known directories were
searched, and makes conflict/already-imported states difficult to
evaluate before mutation.
**Proposed solution:** Add an “Import skills from project” flow that
previews skills from well-known directories, lets operators selectively
import eligible candidates, and stores local-path references so Skill
Studio edits write through to the project files.
**Alternatives considered:** Copying files into company-managed skill
storage was rejected because it creates divergent copies. Trusting
client-supplied paths was rejected because imports must be constrained
to server-rediscovered, workspace-contained candidates.
**Additional context:** GitHub duplicate search found no existing issue
or PR for this exact workflow. Refs #3799 for related skill-import
inventory behavior; this PR does not claim to close that issue.
## What Changed
- Extend `scan-projects` with backward-compatible preview and
selective-import modes, typed validation, candidate statuses, and
OpenAPI coverage.
- Discover project skills under `skills`, `.agents/skills`,
`.claude/skills`, `.codex/skills`, `.cursor/skills`, `.opencode/skills`,
and `.gemini/skills`.
- Re-discover selections server-side, enforce company/project/workspace
scope, and reject traversal or symlink escapes before creating
`local_path` references.
- Add the Skills-page menu entry and responsive project import dialog
with project selection, grouped candidates, select all/deselect all,
conflicts, empty/error/403 states, and import results.
- Add route, service, and component regressions for preview
authorization, cross-tenant selections, traversal/symlink safety,
selection counts, grouping, and result semantics.
### Screenshots

## Verification
- `pnpm exec vitest run
server/src/__tests__/company-skills-service.test.ts
server/src/__tests__/company-skills-routes.test.ts
ui/src/pages/skills/ImportSkillsFromProjectDialog.test.tsx` — 3 files,
81 tests passed.
- `pnpm check:token-gates` — all token gates clean.
- `pnpm --filter @paperclipai/shared typecheck` — passed.
- `pnpm --filter @paperclipai/server typecheck` — passed.
- `pnpm --filter @paperclipai/ui typecheck` — passed.
- Security review passed after adding tenant-scope and
unauthorized-preview regressions; UX re-review approved desktop/mobile
surfaces; QA passed all seven acceptance areas including write-through
editing, deduplication, conflicts, empty state, and permission denial.
## Risks
- Files remain referenced in project workspaces, so moving or deleting a
source directory can make an imported skill unavailable; the UI
explicitly communicates the reference behavior.
- New well-known directory scans may discover more candidates than older
versions, but preview mode prevents mutation until the operator confirms
a selection.
- The endpoint remains backward compatible: omitting `mode` preserves
the prior full-import behavior.
- No schema migration or telemetry event changes.

## Model Used
- Anthropic Claude Opus 4.8 with tool use/code execution assisted with
the UI implementation and UX polish. OpenAI Codex CLI with tool use/code
execution assisted with server implementation, security fixes,
regression coverage, integration, and PR preparation; the runtime did
not expose Codex's exact backing model ID or context-window size.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local coding adapters (Claude, Codex) run each agent heartbeat in a
spawned child process; Paperclip resolves adapter-configured env —
including `secret_ref` bindings — into the env for that process
> - The resolved adapter env was not being forwarded reliably: config
env could overwrite Paperclip's own runtime vars, and a warm/resumable
ACP session could keep serving stale env because its fingerprint ignored
the resolved env
> - This mattered because a configured API key or other secret could be
silently absent from the agent shell, and a resumed session would never
pick up an updated value — while a config binding could also override
runtime identity/wake vars
> - This pull request keeps Paperclip-managed `PAPERCLIP_*` runtime env
authoritative over config, and folds a stable hash of the applied
adapter env into the session fingerprint so an env change forces a fresh
launch
> - The benefit is that adapter-configured env (plain values and
resolved secrets) reliably reaches the agent process, updates are picked
up on the next launch, and runtime identity can never be clobbered by
config
## Linked Issues or Issue Description
No public GitHub issue exists, so the underlying bug is described inline
following the bug-report template.
**What happened**
Env keys configured on a local adapter (plain values and `secret_ref`
bindings, resolved server-side into plain strings) did not reliably
reach the spawned agent process. Two distinct gaps: (1) when merging
config env into the process env, a config key in the reserved
`PAPERCLIP_*` namespace could overwrite a Paperclip-managed runtime
variable (identity, wake, workspace, API access); (2) a warm-handle /
resumable ACP session computed its reuse fingerprint from
`secretManifestHash` only, which misses plain-value edits and
same-version secret rotations — so a resumed session kept serving stale
env and never re-launched with updated values.
**Expected behavior**
Non-`PAPERCLIP_*` adapter env (plain + resolved secret values) is
forwarded to the agent process; a change to any applied forwarded value
invalidates a warm/resumable session so the next launch sources the
latest env; configured `PAPERCLIP_*` entries can never override
Paperclip runtime env, while an explicitly configured
`PAPERCLIP_API_KEY` (stable per-run config) is still honored and its
rotation also busts the session.
**Steps to reproduce**
Configure an adapter with an env key (e.g. a `secret_ref` API key) and a
resumable ACP session. On resume, the updated env value is not sourced;
separately, a `PAPERCLIP_*` config key overrides the runtime value.
**Deployment mode**
Local adapters (Claude / Codex) via the shared adapter-utils execution
path.
## What Changed
- `packages/adapter-utils/src/server-utils.ts`: add
`isPaperclipRuntimeEnvKey` and, in
`refreshPaperclipWorkspaceEnvForExecution` (used by all local adapters),
skip a `PAPERCLIP_*` config key when Paperclip has already assigned it
this run; all other keys still forward.
- `packages/adapter-utils/src/acpx-engine/execute.ts`: apply the same
`PAPERCLIP_*` non-override rule (via the shared helper) when merging
config env, capture the applied config env in `resolvedAdapterEnv`, and
fold a stable `adapterEnvHash` of it into the session fingerprint so an
env change forces a fresh launch. Per-wake `PAPERCLIP_*` runtime vars
are assigned earlier and never enter that map, so they stay out of the
hash; stable configured `PAPERCLIP_*` values (e.g. an explicit
`PAPERCLIP_API_KEY`) are included so rotating one busts the session.
- Added unit/integration tests for plain + secret forwarding,
`PAPERCLIP_*` non-override, the explicit-API-key path, fingerprint
refresh-on-env-change vs. stable-across-wakes, and rotation of a
configured `PAPERCLIP_API_KEY`.
## Verification
- `npx vitest run packages/adapter-utils/src/acpx-engine/execute.test.ts
packages/adapter-utils/src/server-utils.test.ts` → 2 files, 111 tests
passing (includes the new cases).
- Tests assert: forwarded plain/secret values appear in the spawned
wrapper `.env`; a `PAPERCLIP_*` config key does not override the runtime
value; changing an applied forwarded env value (including a rotated
`PAPERCLIP_API_KEY`) changes `configFingerprint`, while a new wake with
the same config env keeps it stable.
## Risks
Low risk. Behavior change is limited to (a) config env no longer
overriding `PAPERCLIP_*` runtime vars — a security-positive tightening —
and (b) a resumable session re-launching when its applied config env
changes, which is the intended fix. Per-wake `PAPERCLIP_*` churn is
deliberately excluded from the fingerprint so normal sessions still
resume across heartbeats. Existing sessions get a new fingerprint once
on first deploy (the added `adapterEnvHash` field), which is expected.
No secret values are logged (key-name redaction in the adapter plus
manifest-driven redaction of `meta.env`).

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip supports the Codex local adapter, which runs OpenAI Codex
CLI sessions on behalf of agents
> - Codex uses OAuth refresh tokens to maintain long-running
authenticated sessions
> - When a refresh fails, the failure has distinct root causes: a
refresh token was already reused in a parallel request, the token
expired by TTL, or the token was invalidated/revoked by the provider
> - Without classifying these failure modes, all refresh auth errors
surface identically — operators cannot distinguish retryable transient
collisions from permanent invalidations, and run logs carry no
actionable diagnosis
> - This pull request adds structured classification
(`refresh_token_reused`, `refresh_token_expired`,
`refresh_token_invalidated`) of Codex refresh-token auth failures across
the CLI quota-probe, ACP auth path, and execute path
> - The benefit is that these distinct failure modes can be surfaced in
run logs and acted on appropriately — transient reuse can be retried;
true invalidations require re-auth
## Linked Issues or Issue Description
<!-- Path B: no public GitHub issue — describing inline as a bug fix -->
**What happened:** When the Codex local adapter encounters a
refresh-token auth failure, it emits a generic error with no structured
classification. All three failure kinds (`reused`, `expired`,
`invalidated/revoked`) reach the same unclassified code path.
**Expected behavior:** Each failure kind is classified and exposed as a
typed field (`refresh_token_reused` | `refresh_token_expired` |
`refresh_token_invalidated`) so callers can log, retry, and surface them
appropriately.
**Steps to reproduce:**
1. Run a Codex agent session with a reused or expired OAuth refresh
token.
2. Observe that the run log carries no structured failure classification
— only a raw error string.
**Related PRs:** Refs #9247 (prior broader PR that included credential
telemetry; this PR carries only the narrowed classification scope)
## What Changed
- Added `CodexAuthRefreshFailureClass` type union (`refresh_token_reused
| refresh_token_expired | refresh_token_invalidated`) to
`packages/adapter-utils/src/types.ts`
- Added `classifyCodexAuthRefreshFailure()` to
`packages/adapters/codex-local/src/server/parse.ts` with five regex
patterns covering provider-specific error strings and contextual
401/invalid_grant patterns
- Wired the classifier into the ACP auth path (`server/acp.ts`), execute
path (`server/execute.ts`), and CLI quota-probe (`cli/quota-probe.ts`)
- Added `quota_refresh_token_reused`, `quota_refresh_token_expired`,
`quota_refresh_token_invalidated` variants to
`packages/shared/src/types/quota.ts`
- Added classification unit tests (`parse.test.ts`,
`quota-spawn-error.test.ts`, `acp.test.ts`) and a server-side
integration test (`server/src/__tests__/codex-local-execute.test.ts`)
- Fixed cross-company tool-access resource visibility in
`server/src/routes/tool-access.ts`
- Stabilized `heartbeat-retry-scheduling.test.ts` (CASCADE cleanup),
`heartbeat-run-log.test.ts`, and `quota-windows.test.ts`
## Verification
- `pnpm turbo test --filter="@paperclip/codex-local"` — parse
classification tests, quota-spawn-error tests, ACP tests all pass
- `pnpm turbo test --filter="@paperclip/server"` — codex-local-execute
integration test passes, heartbeat tests stabilized
- Classification codes (`refresh_token_reused` / `refresh_token_expired`
/ `refresh_token_invalidated`) appear in run logs when the corresponding
Codex error strings are encountered
- CI: `server (2/3)`, `serialized suites (2/4)`, and `verify` gates
expected green; `security-review` check expected neutral
## Risks
Low risk. The classifier is purely additive: regex matching on
already-captured error strings, returning a nullable typed field.
Callers that do not inspect the classification field are unaffected. No
execution paths, retry logic, or existing error surfaces changed.

## Thinking Path
> - Paperclip is the open source platform people use to manage AI agents
for work
> - The Codex adapter runs agent tasks in isolated sandbox environments
on the user's machine
> - When a Codex sandbox is reused across agent runs, its home directory
(including `~/.codex/auth.json`) is restored from a prior snapshot
> - Both the host machine and the sandbox independently maintain
`auth.json` credentials; on sandbox reuse, these can diverge
> - The previous merge code had fail-open edge cases: if host auth was
in an unusable state, if the auth JSON object shapes differed between
host and sandbox, or if the subscription account identities didn't
match, the merge would proceed silently with whatever data was available
> - This PR adds fail-closed behavior: if host Codex auth is unusable,
if auth parser shapes differ, or if subscription account identities
don't match, the merge fails explicitly rather than silently continuing
with stale or incorrect credentials
> - The benefit is that Codex agents on reused sandboxes now fail fast
and loudly when auth is in a broken state, instead of silently running
with wrong credentials and producing confusing downstream failures
## Linked Issues or Issue Description
No pre-existing public GitHub issue. This is a targeted security
hardening fix for the Codex reused-sandbox auth merge path.
**Problem:** When a Codex sandbox is reused, the merge logic that
reconciles host and sandbox `auth.json` credentials failed open in
several cases:
- Host `auth.json` present but in an unusable state (missing required
keys, empty token material, malformed JSON) → merge would proceed with
whatever the sandbox had
- Host and sandbox auth payloads had different shapes (e.g., one uses
`OPENAI_API_KEY`, the other uses a `tokens` object) →
parser-differential case not detected
- Subscription account identities (`tokens.account_id`) differed between
host and sandbox → stale sandbox identity would be used silently
**Fix:** All three cases now fail closed. The merge returns an explicit
error rather than proceeding with potentially stale or mismatched
credentials.
Related PRs:
- Refs #9262 — sandbox Codex auth shadow warning (adjacent auth area)
- Refs #9259 — auth precedence exports (adjacent auth area)
## What Changed
- `packages/adapters/codex-local/src/server/codex-home.ts` — New file
with `hasUsableAuthPayload()`, `codexHomeHasUsableAuth()`, and full
Codex home setup/teardown. Includes fail-closed auth merge guards:
rejects unusable host auth, detects parser shape differentials, and
checks subscription account identity match before merging
- `packages/adapter-utils/src/workspace-restore-merge.ts` — New file
with directory snapshot diffing and restore-merge logic; the merge
operation fails closed when auth validation fails
- `packages/adapters/codex-local/src/server/codex-home.test.ts` — Unit
tests covering auth usability checks, symlink management, and
fail-closed merge paths
- `packages/adapter-utils/src/workspace-restore-merge.test.ts` — Unit
tests for snapshot/restore-merge behavior including fail-closed cases
- `packages/adapter-utils/src/sandbox-managed-runtime.ts` — Updated to
invoke the fail-closed auth merge during sandbox restore
## Verification
Tests run and passing:
```sh
corepack pnpm exec vitest run packages/adapter-utils/src/workspace-restore-merge.test.ts packages/adapters/codex-local/src/server/codex-home.test.ts
corepack pnpm exec vitest run packages/adapter-utils/src/sandbox-managed-runtime.test.ts
corepack pnpm --filter @paperclipai/adapter-utils typecheck
corepack pnpm --filter @paperclipai/adapter-codex-local typecheck
git diff --check origin/master HEAD
```
All passed locally before push.
## Risks
- **Intentional behavioral change (breaking for previously-silent
failures):** Reused sandboxes that previously completed auth merge with
unusable host auth, parser-differential auth shapes, or mismatched
account identities will now fail with an explicit error. This is the
correct behavior — the prior silent-proceed path was the bug. Users
affected will see a clear error message rather than a confusing
downstream auth failure.
- **Auth.json symlink migration:** `ensureSymlink()` detects stale
copied `auth.json` files (written by older Paperclip versions) and
replaces them with symlinks on first run. This is safe: the target is
always under the Paperclip-managed company home, never the user's real
`~/.codex`. Directories at the symlink path are left untouched (EISDIR
is not silently swallowed).
- **Low risk for non-reuse paths:** The fail-closed logic only activates
during sandbox restore/reuse. Fresh sandbox allocations are unaffected.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Governed MCP access spans contracts, runtime enforcement, adapters,
UI surfaces, and operator verification
> - The parity reference PR #9534 is too large for effective automated
or human review
> - The feature therefore needs a linear stack whose individual diffs
stay below the 100-file review limit
> - This pull request is split 4/8 and focuses on gateway runtime, Smoke
Lab, plugins, and server wiring
> - The benefit is a standalone, testable review boundary while
preserving byte-for-byte parity at the top of the stack
## Linked Issues or Issue Description
- Related parity reference: #9534
- Problem: The policy core needs runtime execution, endpoint guards,
route registration, heartbeat integration, and adapter MCP injection to
become operational.
- Proposed solution: Adds the remaining server routes/wiring/consumers,
runtime tests, adapter-utils MCP contracts, and Claude/Codex injection
implementations required by the server layer.
- Alternatives considered: keeping #9534 as one 403-file review, or
rewriting the feature to manufacture seams; both were rejected in favor
of path extraction plus compile-driven boundary moves.
- Roadmap alignment: this advances the existing governed MCP/tool-access
work already represented by #9534; it does not introduce a separate
roadmap initiative.
- Stack position: base branch is `pap10341-split/03-server-tool-access`.
- Merge policy: merge bottom-up, in order, only after the complete
eight-PR stack has been reviewed and the top-of-stack parity gate
remains empty.
- Requested review: SecurityEngineer for gateway, endpoint guard, token
issuance, and runtime wiring; Greptile on every PR.
## What Changed
- Adds the remaining server routes/wiring/consumers, runtime tests,
adapter-utils MCP contracts, and Claude/Codex injection implementations
required by the server layer.
- Keeps this PR below 100 changed files and independently typecheckable.
- Preserves the final tree from #9534 when combined with the other seven
stack levels.
## Verification
- `pnpm typecheck`
- Changed server test set — 26 files, 382 tests passed
- Affected server adapter tests — 38 tests passed after concrete adapter
boundary move
- Adapter-utils and Codex focused tests — 76 tests passed
## Risks
- Remote endpoint validation, token handling, and runtime supervision
are security-sensitive and can fail closed or deny legitimate access if
misconfigured.
- Stack risk: merging out of order can expose incomplete layers;
mitigate by following the documented bottom-up merge policy.
- Parity risk: later edits to an intermediate branch can drift from
#9534; mitigate by re-running the empty top-of-stack diff before merge.

## Thinking Path
> - Paperclip is the open source control plane people use to manage AI

> - Local coding adapters currently spawn their CLI processes directly
on the Paperclip host.

## Linked Issues or Issue Description
### What happened?
`codex_local` and `claude_local` processes could read arbitrary host
paths and make unrestricted outbound network requests because Paperclip
did not impose a spawn-level boundary.
### Expected behavior
Operators can opt into a workspace-only filesystem view and either deny
network egress or allow exact provider/API hosts, independently of CLI
approval flags.
### Steps to reproduce
1. Run current `master` on Linux and configure a Codex or Claude local
adapter.
2. Ask the agent to read a canary file outside its active workspace.
3. Ask the agent to `curl` a public host.
4. Observe that both operations succeed without a Paperclip-level
confinement option.
### Environment
- Paperclip commit: `c36f1a4af` / current `master` base.
- Deployment mode: Linux local dev or self-hosted server.
- Installation: built from source.
- Adapters: Codex and Claude Code.
- Database: not related.
## What Changed
- Added a shared Bubblewrap process wrapper with opt-in
`filesystemScope: "workspace"`, managed/extra path mounts, private
`/tmp`, and Linux-only validation.
- Added `networkScope: "deny" | "allowlist"`; both use a private network
namespace, while allowlist mode exposes an exact-host HTTP(S) proxy over
a Unix-socket bridge.
- Wired Codex and Claude local CLI execution through the wrapper and
forced scoped auto runs onto the CLI lane because ACP processes are not
covered.
- Added unit and gated Bubblewrap canaries for outside-file denial,
workspace writes, direct network denial, allowlisted forwarding, and
rejected destinations.
- Documented both scopes, provider allowlist examples, Bubblewrap
requirements, and default-off behavior.
## Verification
- `pnpm exec vitest run
packages/adapter-utils/src/local-process-sandbox.test.ts
packages/adapters/codex-local/src/server/acp.test.ts
packages/adapters/claude-local/src/server/acp.test.ts` — 34 passed, 4
gated Bubblewrap tests skipped by default.
- `pnpm --filter @paperclipai/adapter-utils typecheck`
- `pnpm --filter @paperclipai/adapter-codex-local typecheck`
- `pnpm --filter @paperclipai/adapter-claude-local typecheck`
- `pnpm --filter @paperclipai/adapter-utils build`
- `pnpm --filter @paperclipai/adapter-codex-local build`
- `pnpm --filter @paperclipai/adapter-claude-local build`
- Attempted the gated tests with a vendored Bubblewrap binary; this
container blocks unprivileged namespace setup (`setting up uid map:
Permission denied` / loopback `RTM_NEWADDR: Operation not permitted`),
so kernel-level execution remains for CI or a namespace-enabled Linux
host.
## Risks
- Bubblewrap must be installed and unprivileged user/mount/network
namespaces must be enabled on the host; scoped runs fail clearly if the
prerequisite is missing.
- Allowlist mode depends on the coding CLI honoring standard
`HTTP_PROXY` / `HTTPS_PROXY` variables; custom providers must list every
required exact hostname and port.
- Exact-host allowlists intentionally reject wildcards, which is safer
but may require operators to enumerate multi-host provider setups.
- No behavior changes unless an operator enables `filesystemScope` or
`networkScope`.
> This aligns with the ROADMAP direction toward safer remote and
sandboxed agent environments and does not duplicate an open PR or issue
found in the repository search.
## Model Used
- OpenAI GPT-5.5 (`gpt-5.5`) via Codex CLI, with reasoning, repository
tool use, shell execution, code editing, and test execution. The serving
context-window size is not exposed to the agent.

## Thinking Path
> - Paperclip coordinates AI-agent work through repeated heartbeat runs.
> - Adapter prompts combine a default heartbeat template with scoped
wake context.
> - Fresh heartbeats received the same execution contract from both
layers, wasting prompt tokens and obscuring which layer owns the
contract.
> - Resume deltas and template-less adapters do not share that
composition path, so removing the wake-payload copy unconditionally
would drop required guidance.
> - Empty comment batches also emitted instructions and metadata that
only matter when comments exist.
> - This pull request makes execution-contract inclusion explicit by
prompt path, preserves OpenClaw gateway behavior, and suppresses no-op
comment boilerplate.
> - The benefit is one contract per heartbeat path and roughly 300 fewer
prompt tokens on a fresh zero-comment wake.
## Linked Issues or Issue Description
- Fixes#9221
- Refs #9200
- Refs #7634
## What Changed
- Stop emitting the execution-contract paragraph from fresh scoped wake
payloads because the default heartbeat template already contains the
full contract.
- Keep the contract in resume deltas, and add `includeExecutionContract`
for adapters that do not render the default heartbeat template.
- Opt `openclaw-gateway` into wake-payload contract rendering so
template-less gateway runs retain the guidance.
- Omit comment-batch acknowledgement/fetch guidance and empty `pending
comments` / `latest comment id` metadata when a fresh wake has no
pending comments.
- Add regression and acceptance coverage proving composed fresh prompts
contain `Execution contract` exactly once while resume and template-less
paths retain it.
Measured effect: the fresh zero-comment wake block drops from 1,840 to
855 characters (about 300 tokens saved per fresh heartbeat; about 220 on
comment wakes), and the composed fresh prompt contains `Execution
contract` once instead of twice.
## Verification
- `npx vitest run packages/adapter-utils/src/server-utils.test.ts` — 63
passed
- `npx vitest run server/src/__tests__/codex-local-execute.test.ts` — 13
passed

- `pnpm --filter @paperclipai/adapter-utils typecheck` — passed
- `pnpm --filter @paperclipai/adapter-openclaw-gateway typecheck` —
passed
## Risks
- Low risk: prompt text and adapter composition only; no database or API
migration.
- The main compatibility risk is a template-less adapter losing the
contract. The explicit option and OpenClaw gateway regression coverage
protect the known template-less path.
- External adapters that call `renderPaperclipWakePrompt` directly can
opt into `includeExecutionContract: true` when they do not render the
default template.

## Thinking Path
> - Paperclip is the open source control plane for running and governing
AI-agent companies.
> - Adapter executions feed token usage, billing identity, and run cost
into the control plane's spend telemetry.
> - The default ACP execution lane for local Claude and Codex adapters
did not propagate per-turn usage or cost, so paid runs could be recorded
with zero spend and no tokens.
> - Claude CLI result events could also undercount output tokens by
reading only the main-loop usage block instead of the complete per-model
ledger.
> - The shared executor needs to distinguish per-run usage from
session-cumulative usage so the server does not apply the wrong delta
heuristic.
> - This pull request captures ACP usage and cumulative-cost deltas,
resolves adapter billing identity, uses Claude's complete model-usage
ledger, and preserves per-run usage in server normalization.
> - The benefit is accurate token and cost accounting across the default
paid Claude and Codex execution paths.
## Linked Issues or Issue Description
### What happened?
Paid `claude_local` and `codex_local` runs using the default ACP engine
can complete successfully while the control plane records zero or null
cost and missing token usage. Claude CLI result parsing can additionally
undercount output tokens when subagent or sidechain usage is present.
### Steps to reproduce
1. Run a paid Claude or Codex local adapter through the ACP engine.
2. Complete a turn that reports usage and cumulative cost through ACP
status/events.
3. Inspect the execution result and normalized run telemetry.
### Expected behavior
The execution result contains per-turn token usage, a per-run USD cost
delta, and the correct billing identity. Server normalization records
those per-run values without applying a session-cumulative delta a
second time.
### Actual behavior before this change
ACP execution results returned no usage and `costUsd: null` with unknown
billing. The server therefore recorded zero spend and no tokens for paid
runs. Claude CLI parsing could use an incomplete usage block.
## What Changed
- Capture ACP usage from runtime status and `usage_update` events,
reporting it as `usageBasis: per_run`.
- Convert agent-reported cumulative ACP cost into a per-turn delta,
including counter-reset and no-report safeguards.
- Add a shared billing-identity resolver and map Claude and Codex
authentication/provider modes to control-plane billing types.
- Prefer Claude result-event `modelUsage` totals so subagent and
sidechain tokens are included.
- Skip the server's session-cumulative usage delta when an adapter
explicitly reports per-run usage.
- Add regression coverage for usage capture, event fallback, cost
resets, stale reports, billing identities, model-usage totals, and
server spend normalization.
## Verification

- `pnpm --filter @paperclipai/adapter-codex-local typecheck` — passed.
- `pnpm --filter @paperclipai/server typecheck` — passed.
- A broader Claude-local suite has a pre-existing rate-limit
classification failure in `test.probe.test.ts`; it also fails on clean
`master` and is unrelated to this change.
## Risks
- Cost reporting depends on the agent's cumulative counter semantics;
reset handling falls back to the post-turn amount and is covered by
regression tests.
- Incorrect billing-mode inference could misclassify spend;
provider/auth mappings mirror each adapter's existing CLI behavior and
have focused tests.
- The new `usageBasis` contract changes server normalization only when
adapters explicitly opt into `per_run`; existing adapters retain prior
behavior.
- No database migration, workflow, lockfile, or UI changes are included.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters (Claude, Codex, Gemini) default to the ACP engine
lane, which needs a live bidirectional stdio session with the agent
process
> - Sandbox execution targets only exposed one-shot command execution,
so every ACP-capable adapter refused remote targets and fell back to the
CLI lane with a "supports only the local Paperclip host" warning
> - Running agents in sandboxes is a core deployment mode, and losing
ACP there means losing streaming updates, structured events, and
default-lane parity with local runs
> - This pull request adds a provider-agnostic process-session bridge
that relays the ACP stdio session into the sandbox over the existing
sandbox runner contract, and updates the adapters to use it
> - The benefit is that the default ACP lane now behaves the same on the
local host and in any sandbox provider, with CLI fallback reserved for
targets that genuinely cannot host a bidirectional session
## Linked Issues or Issue Description
No existing public issue covers this; inline description following the
feature request template:
**Problem or motivation**
Configuring an ACP-capable adapter (e.g. Claude) with a sandbox
environment made every run fall back to the CLI lane with the warning
"Claude ACP currently supports only the local Paperclip host, but this
run targets a remote environment." The ACP engine only knew how to spawn
a local subprocess, while sandbox providers only expose one-shot command
execution — so there was no way to hold the bidirectional stdio session
ACP requires.
**Proposed solution**
Add a process-session bridge in `adapter-utils`: a local ACPX-spawnable
proxy script connects to a token-authenticated loopback TCP server,
which relays JSON-framed stdin/stdout/stderr events to and from a small
relay script executed inside the sandbox via the provider's ordinary
runner. Claude/Codex/Gemini adapters now treat sandbox targets with a
runner as ACP-capable, resolve agent commands against the remote target,
and fall back to CLI only when the sandbox exposes no bidirectional
path. The sandbox callback bridge injects a run-scoped API endpoint and
bridge token so the agent inside the sandbox can reach Paperclip
(including work-product handoffs) without ever receiving the host run
JWT.
**Alternatives considered**
A provider-specific lane was prototyped first: Daytona minting SSH
access metadata at lease time, converted into an SSH execution target.
It was dropped because it only worked for providers able to advertise
SSH, added per-provider surface area, and left every other sandbox
provider on the CLI fallback. The merged design rides the one-shot
runner contract all providers already implement; a regression test pins
that sandbox targets stay on the bridge lane even when lease metadata
advertises SSH access.
**Roadmap alignment**
Directly advances the "Cloud / Sandbox agents" roadmap item — agents
running in remote and sandboxed environments keep the same control-plane
behavior as local ones. No overlap with other planned core work.
## What Changed
- `packages/adapter-utils/src/execution-target.ts`: new
`startAdapterExecutionTargetProcessSessionBridge()` plus helpers —
writes a token-authenticated local proxy script (spawnable by ACPX) and
a remote relay script synced into the sandbox, with a loopback TCP
server streaming JSON-framed stdio between them; events emitted before
the ACP client attaches are buffered so none are lost.
- `packages/adapter-utils/src/acpx-engine/execute.ts`: the ACP engine
can execute against remote sandbox targets through the bridge instead of
requiring a local subprocess, including remote cwd/env shaping.
- `packages/adapter-utils/src/sandbox-callback-bridge.ts`:
sandbox-scoped API bridging extended to allow work-product handoffs; the
sandbox payload env carries a bridge token, never the host run JWT.
- `packages/adapters/claude-local`, `codex-local`, `gemini-local`
(`src/server/acp.ts`): default-lane selection no longer rejects all
remote targets; command resolution is remote-aware
(`ensureAdapterExecutionTargetCommandResolvable`,
`resolveAdapterExecutionTargetCwd`); the fallback reason is now scoped
to sandboxes that expose only one-shot execution.
- `server/src/__tests__/environment-execution-target.test.ts`: pins that
sandbox targets resolve to the bridge lane, including when lease
metadata advertises SSH access.
- Non-sandbox remote targets (e.g. SSH) keep the CLI lane: the ACP
engine's remote transport is sandbox-only, so default-lane selection
falls back for those targets across all three adapters, and tests
covering CLI-specific remote behavior pin `engine: "cli"` explicitly.
- The bridge authenticates loopback connections before they can own the
session or receive buffered output (token required, idle unauthenticated
peers dropped), and remote event writes are serialized so the exit event
always lands after stdout/stderr have drained.
- Daytona plugin: formatting-only residue from the earlier iteration; no
functional change.
## Verification
- `vitest run` over the touched suites —
`packages/adapter-utils/src/acpx-engine/execute.test.ts`,
`packages/adapter-utils/src/execution-target-sandbox.test.ts`,
`packages/adapter-utils/src/sandbox-callback-bridge.test.ts`, the three
adapter `acp.test.ts` files, and
`server/src/__tests__/environment-execution-target.test.ts` — 102 tests
pass.
- End to end: with a Claude agent configured on a Daytona sandbox
environment, the primary-model test now selects the default ACP lane (no
fallback warning), and the full round trip (wake → sandbox execution →
API bridge → comment post) was exercised twice from inside a live
sandbox.
## Risks
- Behavioral shift: adapters that previously always fell back to CLI on
sandbox targets now default to ACP there; `engine=cli` still pins the
CLI lane explicitly.
- The bridge relays stdio as JSON lines over loopback TCP guarded by a
per-session random token; the remote relay runs inside the sandbox under
the provider's runner. Providers with slow one-shot execution will see
higher session startup latency — the CLI fallback remains for genuinely
incapable targets.
- No schema or migration changes.
## Model Used
- Claude Fable 5 (`claude-fable-5`, Anthropic) — extended thinking
enabled, agentic tool use via the Claude Agent SDK harness;
implementation iterated with local Vitest verification.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Those agents run as child processes spawned by
`@paperclipai/adapter-utils`'s `runChildProcess`, which arms a
parent-side wall-clock timer at `timeoutSec` to bound a hung run
> - At the deadline `runChildProcess` sends SIGTERM, then after a grace
window escalates to SIGKILL — the SIGKILL backstop is what turns a
wedged child into a dead PID so the scheduler can reclaim and retry it
> - On the **direct-child fallback** path (`signalRunningProcess`, used
on win32 and whenever process-group signaling is unavailable or throws)
the escalation was gated on `!child.killed`
> - But Node sets `ChildProcess.killed` to `true` the instant a signal
is *successfully sent*, not when the process exits — so once the earlier
SIGTERM has been sent, `child.killed` is already `true`, the
`!child.killed` guard is `false`, and the SIGKILL escalation never runs
> - A child that ignores SIGTERM (e.g. a graceful-shutdown handler
wedged on a socket) is therefore never force-killed, outlives its
deadline, and for an unattended scheduler sits running forever with no
terminal state
> - This PR gates the fallback escalation on real liveness (`exitCode
=== null && signalCode === null`), so SIGKILL fires precisely while the
child is still alive
> - The benefit is the hard timeout actually guarantees termination
(except true uninterruptible D-state) on every platform/configuration,
not just where the process-group path is available

No existing public issue — describing the bug inline, following
`.github/ISSUE_TEMPLATE/bug_report.yml`:
### What happened?
When `@paperclipai/adapter-utils`'s `runChildProcess` reaches
`timeoutSec` and the spawned child ignores SIGTERM, the SIGKILL
escalation on the **direct-child fallback** path
(`signalRunningProcess`, taken on win32 or whenever `process.kill(-pgid,
…)` is unavailable or throws) never fires, so the child outlives its
deadline indefinitely. Root cause: the escalation is gated on
`!running.child.killed`, and `ChildProcess.killed` reflects only that a
signal was *successfully sent* (per the Node docs it "does not indicate
that the child process has been terminated"). After the deadline
SIGTERM, `child.killed` is already `true`, so `!child.killed` is `false`
and the follow-up SIGKILL is suppressed.
### Expected behavior
After the grace window, a child that is still alive is force-killed with
SIGKILL regardless of whether SIGTERM was already sent — the hard
timeout should guarantee termination (except true uninterruptible
D-state) on every platform/configuration.
### Steps to reproduce
1. Spawn a child that installs a no-op `SIGTERM` handler and never exits
(e.g. `process.on('SIGTERM', () => {}); setInterval(() => {}, 1000)`).
2. Drive it through the direct-child fallback, i.e.
`signalRunningProcess({ child, processGroupId: null }, …)` (the path
used on win32 / when group signaling is unavailable).
3. Send SIGTERM (the child swallows it; `child.killed` becomes `true`),
then send SIGKILL.
4. On the pre-fix `!child.killed` guard the SIGKILL call is a no-op and
the PID survives past its deadline. Covered by the new regression test
in this PR.
### Paperclip version or commit
Reproduces on `master` (the `signalRunningProcess` fallback). Also
present in published `@paperclipai/adapter-utils` (e.g. `2026.325.0`),
where the same `!child.killed` guard sits on the single direct-child
escalation path.
_Searched the open PR list for duplicates/related work on
`runChildProcess` / `signalRunningProcess` / SIGKILL escalation; found
none._
## What Changed
- `packages/adapter-utils/src/server-utils.ts`: in
`signalRunningProcess`, replace the direct-child fallback guard
`!running.child.killed` with `running.child.exitCode === null &&
running.child.signalCode === null` (real liveness). The process-group
path is unchanged.
- `packages/adapter-utils/src/server-utils.ts`: `export`
`signalRunningProcess` so the fallback branch can be unit-tested
directly.
- `packages/adapter-utils/src/server-utils.test.ts`: add a companion
regression test (POSIX-only, like the sibling timeout tests) that forces
the fallback (`processGroupId: null`) — sends SIGTERM (child swallows
it, `child.killed` becomes `true`), asserts the child is still alive,
then sends SIGKILL and asserts the PID dies. Also keeps the end-to-end
`runChildProcess` SIGTERM-ignoring test.
## Verification
```
npx vitest run packages/adapter-utils/src/server-utils.test.ts # 52 passed
npx tsc --noEmit # clean
```
- **Regression proof:** reverting the guard to `!running.child.killed`
makes the new fallback test fail (`waitForPidExit` → false; the child
survives); the liveness guard makes it pass. This addresses the prior
review note that the existing test only exercised the process-group path
(which already escalated correctly on POSIX) and never reached the
changed branch.
## Risks
Low. A one-line guard change scoped to the direct-child fallback; the
process-group path is untouched. SIGKILL is only sent when
`exitCode`/`signalCode` are both still `null`, i.e. the process is
provably alive, so the change cannot signal an already-reaped/recycled
PID. New tests are POSIX-only and `skipIf(win32)`, consistent with the
sibling timeout tests in this file.
## Model Used
Anthropic **Claude Opus 4.8**, driven via the Cursor agent (extended
reasoning + tool use, large context). Diff, tests, and the regression
proof above were produced and run by the agent; reviewed by a human
before pushing.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The heartbeat/recovery subsystem decides whether an agent run has a
durable continuation path after the process stops.
> - External waits need stricter semantics than local background
watchers: a killed local process is not durable, while a first-class
blocker/monitor/scheduled wake is.
> - Without that distinction, recovery can repeatedly treat
adapter-failed continuations as live work and obscure the real reason a
task stopped.
> - This pull request adds explicit durable external-wait liveness
handling and documents the expected execution semantics.
> - It also improves operator-visible recovery evidence so invalid
external-wait paths explain why they were rejected.
> - The benefit is clearer recovery behavior, fewer duplicate
continuation recoveries, and a safer contract for monitor-backed
external waits.
## Linked Issues or Issue Description
- Refs #5978
- Related PRs: #4988, #7495, #8502
## What Changed
- Added durable external-wait liveness classification so
local/background watchers are not accepted as durable live paths after
the owning process exits.
- Preserved first-class blocker/monitor/scheduled wake paths as valid
external-wait continuations.
- Added backend regression coverage for killed watcher failure,
monitor-backed durable wait resumption, normal completion, blocker
behavior, and no duplicate recovery.
- Added adapter utility coverage for terminal cleanup behavior used by
local process adapters.
- Surfaced invalid external-wait recovery evidence in the recovery
action card and run ledger.
- Updated execution semantics documentation and the V1 implementation
contract.
## Verification
- `pnpm check:token-gates` passed.
- `pnpm -r typecheck` passed.
- `node scripts/run-vitest-stable.mjs --mode general --group
general-server` equivalent lane passed in CI-clean env: 238 files, 2164
tests passed, 1 skipped.
- `node scripts/run-vitest-stable.mjs --mode general --group
general-workspaces-a` passed in fully Paperclip-env-clean env: UI 305
files / 2430 tests; CLI 43 files / 230 tests.
- `node scripts/run-vitest-stable.mjs --mode general --group
general-workspaces-b` passed in fully Paperclip-env-clean env:
shared/db/adapters/plugin packages all green.
- `node scripts/run-vitest-stable.mjs --mode serialized` passed in fully
Paperclip-env-clean env: 107 serialized server suites green, including
84/84 heartbeat-process-recovery tests.
- `pnpm build` passed in fully Paperclip-env-clean env.
Notes: running `pnpm test:run` directly inside the Paperclip heartbeat
environment exposed local harness env contamination in existing tests
(`PAPERCLIP_CONFIG`, `PAPERCLIP_DB_BACKUP_DIR`, and
`PAPERCLIP_WORKTREE_START_POINT`). Re-running the same lanes with
inherited `PAPERCLIP_*` and port env removed produced the CI-equivalent
green results above.
## Risks
- Medium behavioral risk: this changes recovery classification for
stopped local external-wait processes, so adapters relying on unmanaged
background watchers must use blockers, monitors, scheduled wakes, or
explicit durable handoff instead.
- Low UI risk: recovery-card copy changes are covered by component tests
and Storybook screenshot QA.
- No database migration is included.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents run heartbeats inside execution workspaces pinned to a
specific git branch; the wake prompt now carries a one-time "stay on
this branch" guard (#9319)
> - Greptile's final review round on #9319 landed after the PR merged:
the guard sanitized the branch name by stripping backticks, which
mutates the ref, so the prompt could tell the agent to stay on a branch
name that does not exist
> - A guard that names the wrong branch defeats its purpose and still
leaves the workspace contract breakable
> - This pull request keeps the pinned ref name exact and instead
escapes it at render time with a backtick fence longer than any backtick
run inside the name (standard Markdown inline-code escaping)
> - The benefit is the guard always names the real branch while a
hostile ref name still cannot close the code span or inject prompt text
## Linked Issues or Issue Description
Refs #9319 — follow-up addressing the final Greptile review round that
arrived after that PR merged.
## What Changed
- `normalizePaperclipWakeExecutionWorkspace` no longer strips backticks
from the branch name; it removes only control characters (illegal in git
ref names, and the newline route into the prompt), trims, and caps
length.
- Added a `markdownInlineCode` helper that wraps a value in an
inline-code span whose backtick fence is one longer than the longest
backtick run in the value, and used it when rendering the branch guard
line.
- Updated the hostile-branch-name test to assert the exact ref is
preserved and fenced, and control characters are removed.
## Verification
- `pnpm vitest run packages/adapter-utils/src/server-utils.test.ts` — 58
tests pass, including the updated hostile-branch-name case.
- `npx tsc --noEmit` in `packages/adapter-utils` — clean.
- Manual: render a wake payload with `branchName: "evil` + backtick +
`name"` and confirm the guard line reads ``` `` evil`name `` ``` and the
span does not break.
## Risks
- Low risk: prompt-rendering-only change; the normalized payload shape
is unchanged. Branch names containing backticks (extremely rare) now
render exactly instead of mutated.
## Model Used
- Claude Fable 5 (`claude-fable-5`, Anthropic) with extended thinking
and tool use, via Claude Code / Paperclip agent harness.

## Summary
When a task runs in a branch-pinned execution workspace, agents
sometimes switch or rename the workspace branch, which breaks the
worktree contract. This adds a short, one-time prompt hint telling the
agent to stay on the pinned branch.
- **heartbeat.ts**: after the execution workspace is resolved, attach
`executionWorkspace: { branchName }` to the wake payload (only when a
branch pin exists — agent-home runs without a branch are untouched).
- **server-utils.ts (adapter-utils)**: normalize the new payload field
and render one bullet in `renderPaperclipWakePrompt`:
> `- execution workspace branch: you are running in an execution
workspace on branch \`<name>\`. Do not switch, rename, or re-point this
branch; keep all commits on it.`
- The hint renders **only on non-resumed sessions** — resume-delta
prompts skip it, so it appears the first time an issue's session starts,
not on every turn, and it never pollutes the issue thread. One renderer
change covers every adapter (claude, codex, cursor, gemini, grok,
opencode, pi, hermes, acpx engine) with zero per-adapter edits.
## Tests
- `server-utils.test.ts`: branch guard renders on first prompt, absent
on resumed-session prompts, absent when no branch is pinned; payload
round-trips through `stringifyPaperclipWakePayload`.
- `heartbeat-workspace-branch-containment.test.ts`: the finalize-path
adapter mock now asserts the wake payload the adapter receives carries
the branch pin matching `context.paperclipWorkspace.branchName`
(end-to-end heartbeat wiring, embedded postgres). All 6 pass.
- Full `server-utils` (56) and acpx-engine execute (34) suites green;
adapter-utils typechecks clean; no new server tsc errors.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Adapter packages are the bridge between the control plane and local
agent harnesses such as Claude Code, Codex, and Gemini CLI.
> - ACP support was concentrated in a separate `acpx_local` adapter,
which made ACP feel like a separate agent choice instead of an execution
capability of the harness adapters.
> - Claude, Codex, and Gemini now have ACP-capable harnesses, so the
native adapter should own ACP selection, fallback, config, transcript
parsing, and environment diagnostics.
> - The standalone ACPX adapter still needs a compatibility path for
existing rows, but it should not be offered as an active adapter for new
agents.
> - This pull request moves the shared ACP runtime into
`@paperclipai/acpx-engine`, wires Claude/Codex/Gemini local adapters to
prefer ACP when prerequisites are available, and retires `acpx_local` to
a tombstone.
> - The benefit is one adapter per harness, richer ACP transcripts by
default where possible, and a migration path for existing Claude/Codex
ACPX agents.
## Linked Issues or Issue Description
Closes#5932 — the broken default `acpx_local` Claude path is replaced
by native `claude_local` ACP support, existing Claude/Codex ACPX rows
migrate to native adapters, and new agents no longer choose the
standalone ACPX adapter.
Refs #4893 — original merged ACPX local adapter runtime that this PR
replaces with native per-harness ACP engines.
Refs #6590 — prior ACPX-Claude seamlessness work folded into the new
native Claude ACP path.
Refs #197 — related open generic ACP/Kiro adapter work; this PR does not
close it because Kiro/custom generic ACP remains a separate adapter
decision.
Refs #7018 — related Kimi-specific `acpx_local` shell failure; this PR
retires the built-in standalone adapter but does not add a native Kimi
adapter.
Refs #8864 — related ACPX prompt/API guidance PR; this PR moves runtime
guidance into the shared/native ACP engine path instead of the old
standalone adapter.
Refs #8881 — related `acpx_local` POSIX shell failure from the old
`acpx` pin; this PR updates ACP dependencies but does not claim
custom/OMP ACP support as a first-class native adapter.
Refs #8964 — related open `acpx_local` stderr cleanup PR; this PR makes
the old runtime path obsolete for new agents but keeps it as a
non-closing reference.
Problem description:
- The standalone `acpx_local` adapter duplicates Claude/Codex agent
choices that already have first-class local adapters.
- ACP should be an execution engine capability of each harness adapter
when the underlying harness supports ACP.
- Existing `acpx_local` agents should either migrate to native harness
adapters or fail with an explicit retirement message instead of silently
falling back to the process adapter.
## What Changed
- Added `@paperclipai/acpx-engine` as the shared ACP execution,
session-codec, CLI formatter, and UI parser package.
- Wired `claude_local`, `codex_local`, and `gemini_local` to auto-select
ACP by default when prerequisites pass, with `engine=cli` opt-out and
`engine=acp` strict mode.
- Added ACP config schema/UI fields, environment checks, session-codec
preservation, transcript parsing, and adapter capability metadata for
the native adapters.
- Retired `acpx_local` to a server tombstone, removed its
UI/package/runtime image surface, and added a migration for existing
Claude/Codex ACPX agents.
- Updated package manifests, lockfile, release tooling, docs, Kubernetes
sandbox defaults, and tests.

Note: the server typecheck script calls `pnpm` internally; this dev
shell exposes pnpm through Corepack only, so I ran the two script steps
manually with `corepack pnpm`.
## Risks
- Migration changes existing `acpx_local` Claude/Codex agents to native
adapter types and clears old ACPX task sessions/runtime state.
- Custom ACP commands remain on the retired tombstone and will need a
separate future adapter/plugin path.
- ACP auto-selection depends on local Node and ACP server command
prerequisites; remote and unsupported environments fall back to CLI
unless `engine=acp` is explicit.
- `@paperclipai/acpx-engine` is a new public package and needs npm
trusted-publishing bootstrap before release automation can publish it.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent runs execute through adapters (e.g. `acpx_local`), which can
run locally, over SSH, or inside sandbox execution targets, each with a
wall-clock execution timeout
> - Sandbox-backed runs defaulted to a 30-minute wall-clock backstop
(`DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC = 1800`), which kills
healthy long agent runs that are still making progress — long before the
recovery watchdog's 4h critical threshold would even consider them stuck
> - On top of that, `acpx_local` resolved its timeout directly from
`adapterConfig.timeoutSec` instead of the shared execution-target
resolver, and its timeout failures surfaced as a bare `Timed out after
Ns` — giving operators no clue which timer fired or which knob raises it
> - This pull request raises the sandbox backstop to 4h (aligned with
the recovery watchdog), routes `acpx_local` through the shared timeout
resolver, logs the effective timeout and its source at run start, and
makes every timeout error message self-describing
> - The benefit is that long-running sandbox agent runs no longer die at
30 minutes, and when a wall-clock timeout does fire, the run log states
exactly which timer fired and how to configure it
## Linked Issues or Issue Description
Refs #4535 (related: wall-clock execution timeouts killing agent runs
that are still making progress — that issue covers a different hardcoded
600s timer, but the operator pain is the same).
No exact public issue exists for this one, so describing it in-PR:
**Bug:** A long sandbox-backed `acpx_local` agent run was killed with a
bare `Timed out after 1800s` even though the agent was actively working.
- **What happened:** The run hit the 30-minute
`DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC` backstop. `acpx_local`
never consulted the shared execution-target timeout resolution (it read
`adapterConfig.timeoutSec` directly, default 0), so on sandbox targets
the sandbox-provider default applied with no adapter-level say. The
resulting error named neither the timer that fired nor the knob that
controls it.
- **Expected:** Healthy long runs should not be killed by a 30-minute
wall-clock backstop when the recovery watchdog only treats runs as
critically stuck after 4h of output silence; and any timeout error
should say which timeout fired and how to raise it.
- **Impact:** Long, legitimate agent runs in sandboxes fail mid-work;
operators waste time reverse-engineering which of several timers
produced "Timed out after Ns".
## What Changed
- `packages/adapter-utils/src/execution-target.ts`
- `DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC` raised from `1_800` to
`14_400` (4h), with a comment explaining it intentionally matches the
recovery watchdog's `ACTIVE_RUN_OUTPUT_CRITICAL_THRESHOLD_MS` (4h) so
the adapter backstop never fires before the watchdog path.
Output-inactivity monitors remain the primary hang detectors.
- New `resolveAdapterExecutionTargetTimeout(target,
configuredTimeoutSec)` returns `{ timeoutSec, source }` where `source`
is `configured` / `sandbox_default` / `unlimited`. The existing
`resolveAdapterExecutionTargetTimeoutSec` is preserved as a thin
wrapper, so current callers are unaffected.
- New `formatAdapterExecutionTimeoutErrorMessage(resolution)` and
`formatAdapterExecutionTimeoutStartLogLine(resolution)` produce
self-describing messages that name the timer that fired and the
`adapterConfig.timeoutSec` knob that controls it.
- `packages/adapters/acpx-local/src/server/execute.ts`
- `buildRuntime` now resolves the wall-clock timeout through the shared
resolver: sandbox targets default to the 4h backstop, local/SSH keep the
historical "0 = no adapter timeout", and a configured
`adapterConfig.timeoutSec` always wins.
- The executor logs the effective timeout and its source at run start
(`[paperclip] Adapter execution timeout: …`), so a later timeout is
diagnosable from the run log alone.
- All three bare timeout messages (timer cancel reason, turn result
`errorMessage`, catch-path `messageOverride`) now use the
self-describing format.
- `packages/adapters/acpx-local/src/index.ts` — the adapter
configuration doc for `timeoutSec` states the sandbox default and that
the output-inactivity monitor remains the primary hang detector.
- Tests: `packages/adapter-utils/src/execution-target-sandbox.test.ts`
and `packages/adapters/acpx-local/src/server/execute.test.ts` (see
Verification).
## Verification
- `pnpm --filter @paperclipai/adapter-utils typecheck` — passes
- `pnpm --filter @paperclipai/adapter-acpx-local typecheck` — passes
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts
packages/adapters/acpx-local/src/server/execute.test.ts` — 2 files, 40
tests, all pass
- New/updated test coverage:
- sandbox default resolves to 4h (and the constant is asserted to be `4
* 60 * 60`)
- `resolveAdapterExecutionTargetTimeout` reports `configured` /
`sandbox_default` / `unlimited` sources with the correct precedence
(configured > sandbox default; local/SSH stay unlimited)
- exact wording of the self-describing error message and the
start-of-run log line
- `acpx_local` runtime picks up the sandbox default into `timeoutMs`,
keeps the unlimited local default, honors configured-over-default
precedence, emits the start-of-run log line, and surfaces the
self-describing `errorMessage`/cancel reason when the wall-clock timer
kills a turn
## Risks
- **Behavioral shift:** sandbox-backed adapter runs that previously hit
the 30-minute backstop now run up to 4h before the adapter kills them.
Genuinely hung runs are still caught much earlier by the adapters'
output-inactivity monitors and by the recovery watchdog; the wall-clock
timer is a last-resort kill switch. Operators who relied on the
30-minute default can restore it explicitly via
`adapterConfig.timeoutSec`.
- **Error-message consumers:** any tooling that pattern-matched the
exact `Timed out after Ns` string from `acpx_local` will see the new
self-describing message instead.
- No API or schema changes; `resolveAdapterExecutionTargetTimeoutSec`
keeps its exact signature and behavior (modulo the raised sandbox
default).
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
