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

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.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Claude agents that run in a remote sandbox need a safe in-product
login path
> - The existing host login route cannot open a pseudo-terminal inside
that sandbox
> - The login flow must protect the browser code, the login URL, and the
OAuth token at every step
> - This pull request adds the parser, the runner, a Daytona
pseudo-terminal transport, and a guarded, owner-bound session route
behind an injectable transport
> - The route stays inert in the default build and fails closed until a
sandbox provider binds the live transport
> - The benefit is a company-scoped setup-token flow with one-time
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

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.

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**

**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

## 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

## 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.

## 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.
> - This pull request adds bounded spans and closed attribute helpers
for sandbox startup and execution.
> - The result is better trace data with low cardinality and no secret
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
stays unready for board handoff until that check passes.

## 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.
## Model Used
- 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.
## Model Used
Claude Fable 5 (`claude-fable-5`, Anthropic) via Claude Code — extended

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

passed.
-
`PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/test-home-ci-repro-escalated"
pnpm exec vitest run

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.

## Thinking Path

work

executes the agent
> - Local sandboxes already stage referenced projects for @-mentions

## 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.
## Model Used
OpenAI GPT-5 via Codex. Tool use enabled. Context window not reported in
this run.

## 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.

## Model Used

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.

- GitHub CI is green on PR #10469.
## 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.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The sandbox exec path starts agent commands and passes runtime
options to the server and plugin layers
> - This path kept a noProfile flag after the exec wrappers stopped
sourcing a login profile

## Linked Issues or Issue Description
- No public GitHub issue exists.
### 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
SANDBOX-REQUIREMENTS.md.
## Verification
- `git grep -n "noProfile" -- packages/ server/` returns zero matches.
- `tsc --noEmit` passed for `@paperclipai/adapter-utils`,
`@paperclipai/plugin-sdk`, and `@paperclipai/server`.
- `command-managed-runtime.test.ts` passed: 22/22.
- `environment-runtime.test.ts` passed: 24/24.
## Risks
- Low risk. The flag was already a no-op.
- A hidden external caller may still send the removed field.
## Model Used
- OpenAI GPT-5, tool-enabled.

## 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

work

environments

every start, even when the remote copy already matched

script write and keeps the existing bridge-entrypoint hash gate on the

> - 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.
## Model Used
OpenAI Codex (GPT-5, tool-using coding agent).

## 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.
## Model Used
OpenAI Codex, GPT-5, tool-using code execution mode.

## 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.

## 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.

## 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
> - Agents reading `PAPERCLIP_WAKE_PAYLOAD_JSON` could therefore see a
missing brief while also being told no fallback fetch was needed
> - Long descriptions also need a bounded representation so wake
environments and prompts remain safe
> - This pull request carries the description through the server and
adapter contract, and marks truncated descriptions as requiring fallback
fetch
> - The benefit is that agents receive the actual brief instead of
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.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## 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.
