## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The Paperclip runner needs a safe boundary before it can launch
ACP-compatible agents.
> - A caller-controlled command, model, environment, or frame could
bypass that boundary.
> - The ACPX transport contract in #12386 defines the allowed messages
but does not bind a runtime profile.
> - This pull request defines closed, versioned profiles and validates
the launch inputs around that contract.
> - The benefit is a small and reviewable trust boundary before any ACPX
process can become available.
## Linked Issues or Issue Description
**Agent or provider**
ACPX sidecar support for the qualified Pi, Claude, and Codex ACP
servers.
**Why this adapter is useful**
The runner needs one bounded process boundary for ACP-compatible
providers. A closed profile prevents an untrusted run from selecting an
arbitrary executable, package version, or model.
**How the agent is invoked**
A later pull request will launch an internal sidecar from an exact
profile. This pull request only validates profiles, environment values,
and protocol frames. It does not add an executable dependency or enable
an adapter.
**Additional context**
This pull request is stacked on #12386. It keeps the existing direct
adapters and the Codex runner path unchanged.
## What Changed
- Add a closed profile table for the qualified Pi, Claude, and Codex ACP
servers.
- Require the exact qualified model and return an isolated profile value
to callers.
- Add an agent-specific environment allowlist with entry and aggregate
size limits.
- Add strict parsing for bounded sidecar requests and structured plan
values.
- Reject unknown fields, unsupported protocol versions, invalid
identifiers, null bytes, cyclic values, and oversized input.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — 40 files and 362 Vitest tests passed; 11
Node contract tests passed.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 6 files and does not change `pnpm-lock.yaml`, a
workflow, a package dependency, or a public export.
## Risks
The main risk is accepting more launch state than the sidecar needs. The
implementation uses an agent-specific allowlist, rejects null bytes, and
enforces per-entry and aggregate bounds. This pull request does not
launch a process or expose a new adapter, so production and
direct-adapter behavior remain unchanged.
## Model Used
OpenAI Codex with GPT-5 and repository tool use.

## Linked Issues or Issue Description
Refs #11965
This is stack 1 of 11. It replaces the first reviewable part of #11965.
## What Changed
- Add guarded remote MCP setup and credential handling.
- Add PostHog OAuth and API key connection methods.
- Add focused server, shared contract, and UI coverage.
- Keep the migration replay-safe and idempotent.
- Give the late-close security regression the same 10-second CI headroom
as the adjacent real-timer handshake test.
- Synchronize fake-timer handshake tests at the exact ensure-session
boundary so real filesystem setup cannot race the fake deadline.
- Drive PTY overflow coverage only after listener registration so
scheduling cannot reorder the test fixture.
## Verification
- pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts
server/src/__tests__/plugin-worker-manager.test.ts (220 passed; affected
cases also passed five focused stress repetitions)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never leaks a
sandbox-provided value from a late close rejection into logs or the
result"` (1 passed)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never
promotes a late ensureSession resolution|closes a late-resolving real
handle exactly once"` (2 passed)
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
## Risks
- Remote endpoint validation can reject configurations that previously
passed without checks.
- OAuth configuration errors can block setup until the operator corrects
the provider settings.
- The migration uses guarded statements so repeated execution is safe.
- The test-only synchronization changes do not affect runtime behavior;
they remove filesystem/fake-clock and listener-registration races
observed under parallel CI load.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip uses adapters to connect agents and model providers to its
control plane
> - The sandbox login panel supports displayed-code login for selected
adapters
> - Grok users need the same login path and a private credential home
for later runs
> - This pull request adds Grok support to the shared device-login path
and preserves the existing Codex path
> - The benefit is one secure login flow for both adapters with
company-scoped credential storage
## Linked Issues or Issue Description
**Agent or provider**
Grok Local needs displayed-code login support in the sandbox login
panel.
**Why this adapter is useful**
This change lets users sign in to Grok from the sandbox login panel. It
also gives later Grok runs access to the stored credential.
**How the agent is invoked**
The Grok local adapter uses its login command through the shared
displayed-code login flow. Later runs receive the managed home through
`GROK_HOME`.
**Additional context**
The change uses adapter-scoped login lifecycle handling. It stores the
credential in a company-scoped directory with mode `0700`, and it stores
the credential file with mode `0600`.
## What Changed
- Rename the shared device-login modules to adapter-neutral names.
- Scope the shared login lifecycle to a closed adapter set.
- Return the device-login URL that the provider prints.
- Add the Grok prompt parser, login command, capability, and login panel
entry.
- Store the Grok credential in a private, company-scoped home directory.
- Pass `GROK_HOME` to later Grok runs.
- Add tests for the Grok adapter, the Daytona sandbox provider, the
server login path, and the user interface.
## Verification
- Run `pnpm vitest run
packages/adapters/grok-local/src/server/adapter-auth-promotion.test.ts`.
- Run the Grok adapter package suite.
- Run the Daytona sandbox provider suite.
- Run the server device-login suites.
- Run the user interface suite.
- Confirm the full CI suite passes.
## Risks
The change extends shared login lifecycle code to another adapter. A
regression could affect Codex login. The credential path uses explicit
`chmod` calls to keep the directory at mode `0700` and the file at mode
`0600`.
## Model Used
OpenAI Codex, GPT-5. The runtime used tool calls and code review
support. The runtime did not provide a context-window value.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Adapter utilities start and control agent sessions.
> - The ACP startup handshake can stay pending when the sandbox
transport closes.
> - A pending handshake keeps the run active and prevents a clear
operator result.
> - This pull request bounds the handshake and fences its abandoned
promise.
> - The result gives each startup failure a terminal state and a safe
host-authored diagnostic.
## Linked Issues or Issue Description
No matching public issue or pull request appeared in the GitHub search
for this failure. The issue details follow.
**What happened?**
The adapter engine awaited `runtime.ensureSession()` without a startup
bound. A lost sandbox transport could leave the await pending.
**Expected behavior**
The engine must end the run when the startup deadline expires or the
duplex transport closes. A late session result must not reopen the
settled run.
**Steps to reproduce**
1. Start an ACP-backed agent run.
2. Keep the ACP initialization call pending.
3. Let the startup deadline expire or close the duplex transport.
4. Confirm that the run reaches a terminal state and that a late session
result does not reopen it.
**Paperclip version or commit**
`66e1c0df8b23cb8354b36dd446d9548dc4389191` merge base.
**Deployment mode**
Local dev (`pnpm dev`).
**Installation method**
Built from source (`pnpm dev`).
**Agent adapter(s) involved**
Custom / external plugin adapter.
**Database mode**
Not database-related.
**Relevant logs or output**
The new tests use fixed host-authored diagnostics for handshake guard
failures and late close failures.
**Additional context**
The change updates the execution semantics document and adds regression
coverage. The three existing failures in `execute.test.ts` also occur at
the merge base.
## What Changed
- Bound `runtime.ensureSession()` with a startup deadline and a duplex
transport loss check.
- Added terminal error codes for handshake timeout and transport loss.
- Fenced late session resolution and rejection so the settled run has
one owner.
- Suppressed sandbox-controlled diagnostic values on the guard-failure
and late-close paths.
- Added regression tests for timeout, transport loss, late resolution,
and late close rejection.
- Documented the startup live-path contract.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit` exits 0.
- The engine test suite runs from the repository root.
- The new regression cases pass.
- The three known failures remain the only failures and also fail at the
merge base. The board approved this pre-existing test exception.
- Cold start and session resume cases pass.
- All required GitHub checks pass.
- Greptile reports 5/5 with no open P2 findings, recommendations, or
follow-ups.
## Risks
The startup guard changes only the ACP startup path. A slow but valid
startup can now end at the configured deadline. The fence closes a late
handle once and records fixed host-authored diagnostics.
## Model Used
OpenAI Codex, GPT-5, current model version, tool use and code execution,
with the full task context.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter runtime settles each run through a duplex control
channel
> - A lost channel can leave the remote session-close call without a
usable peer
> - The call has no deadline, so run teardown can wait for the full
adapter timeout
> - This pull request skips that remote call after the runtime latches
channel loss
> - The benefit is faster run finalization while the local cleanup
effects remain
## Linked Issues or Issue Description
**What happened?**
The run teardown placed a remote session-close call over a duplex
control channel that the runtime had already latched as lost. The call
blocked until the adapter execution timeout released it.
**Expected behavior**
Run teardown should release the local warm handle and continue when the
duplex control channel has already failed.
**Steps to reproduce**
1. Start an adapter run with the duplex control channel.
2. Latch a channel-loss state before settlement.
3. Use a runtime whose close call never resolves.
4. Confirm that teardown returns without a remote close call.
**Paperclip version or commit**
Commit d966069a78.
**Deployment mode**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific. The change applies to the shared adapter runtime.
**Database mode**
Not database-related.
**Additional context**
Pull request #12373 used a larger approach for the same failure. The
board closed that pull request. This pull request contains the smaller
change.
## What Changed
- Add the required readonly `skipRemoteClose` field to the runtime
settlement plan.
- Set the field from the latched channel-loss state on the turn-finalize
plan.
- Set the field to `false` on every other settlement plan.
- Release the warm handle locally before the `end_session` step returns
without the remote call.
- Add a test that drives the lost-channel path through the settlement
sequence.
## Verification
- `./node_modules/.bin/tsc --noEmit -p packages/adapter-utils`
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` passes the new
test. Three existing tests fail on the merge base: two
session-fingerprint tests and one workspace-hints test.
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/run-fault-matrix.test.ts` reports
20 passed.
- Full CI will run on this pull request.
## Risks
The skipped remote close also skips the vendored runtime caller for
`closeBackendSession`. The run can keep a retained client after duplex
loss. A separate follow-up owns that residual. The environment lease
still releases in the teardown `finally` block.
## Model Used
OpenAI Codex, GPT-5, with tool use and code review assistance.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters stage referenced projects into controlled sandboxes
> - The ignore scan must preserve exact Git path bytes and fail closed
on unsafe input
> - Unbounded ignored-path data and raw diagnostics can harm resource

## Linked Issues or Issue Description
**What happened?**
The referenced-project ignore scan trimmed NUL-delimited Git paths. It
also accepted a large ignored-path set and exposed raw failure details
through staging errors and warnings.
**Expected behavior**
The scan must preserve leading and trailing whitespace in Git paths. It
must reject oversized ignored-path data and expose only fixed failure
categories.
**Steps to reproduce**
1. Run the referenced-project ignore scan with paths that start or end
with whitespace.
2. Provide more than 10,000 ignored entries or more than 2 MiB of path
bytes.
3. Trigger a scan failure and inspect the reported reason.
**Paperclip version or commit**

**Deployment mode**
Built from source.
**Installation method**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific.
**Database mode**
Not database-related.
**Additional context**
This change covers the overlay diff, untracked, deleted, and ignored Git
paths. It also retries only typed scheduler saturation failures.
## What Changed
- Preserve all bytes in NUL-delimited Git path records.
- Bound ignored-entry count and total UTF-8 path bytes during parsing.
- Redact scan failure details to three fixed reason categories.
- Retry only the typed scheduler saturation error, with three total
attempts and 1 second then 2 second waits.
- Add tests for path whitespace, limits, diagnostics, retry behavior,
and scheduler code parity.
## Verification
- `npx tsc --noEmit` in `packages/adapter-utils` passed.
- `npx vitest run packages/adapter-utils` passed with 977 tests and 4
skipped.
- Continuous integration must run the server suite and the full
repository gates.
## Risks
The scan now rejects ignored-path data above fixed limits. Saturation
retries add up to 3 seconds before a final failure. The resolver still
fails closed for all other errors.
## Model Used
OpenAI GPT-5. The model used tool calls, code inspection, and command
execution. The exact context window and reasoning mode are not exposed
by the runtime.

## Linked Issues or Issue Description
Refs #7029
Refs #12138
Refs #12147
**What happened?**
A skill-capable legacy local agent could start without
`paperclipai/paperclip/paperclip`. This happened when the agent had no
stored skill preference. An explicit empty preference also removed the
skill. The agent then reported that the Paperclip skill was not
available.
**Expected behavior**
Every skill-capable legacy local adapter must mount the Paperclip
operational skill when the runtime inventory contains it. Optional
skills must remain configurable. The native runner must keep its current
protocol-based behavior.
**Steps to reproduce**
1. Create a non-CEO `codex_local` agent without `paperclipSkillSync`
preferences.
2. Start a legacy heartbeat.
3. Inspect the managed `CODEX_HOME/skills` directory.
4. Observe that the Paperclip skill is absent before this change.
**Paperclip version or commit**
The problem reproduces on `master` before this pull request. PR #7029
introduced the configured-only selection behavior.
**Deployment mode**
Local development and self-hosted legacy local adapters.
## What Changed
- Added a shared legacy skill resolver that always selects the canonical
Paperclip operational skill when it is available.
- Applied the resolver to direct adapter execution, ACPX execution,
skill snapshots, and persistent skill sync.
- Added Hermes skill materialization at sync and run boundaries.
- Aligned Cursor, Gemini, and OpenCode execution-time injection with the
configured child `HOME`.
- Made Hermes stop execution when another installation blocks the
required operational skill.
- Kept optional skills controlled by `paperclipSkillSync.desiredSkills`.
- Kept `paperclip_runner` on the configurable-only resolver.
- Added regression coverage for missing preferences, empty preferences,
each skill-capable legacy adapter, ACPX, Hermes, and native runner
isolation.
- Documented the legacy runtime invariant.
## Verification
- `pnpm -r typecheck` passed on the pushed commit.
- `pnpm build` passed on the pushed commit.
- The adapter utility regression suites passed: 236 tests.
- The changed server adapter suites passed: 48 tests across 12 files.
- The OpenCode adapter suite passed: 8 tests.
- The Hermes adapter suite passed: 7 tests.
- `git diff --check` passed.
- `pnpm test:run` is not clean on this macOS host. The command reported
failures in unchanged workspace and filesystem suites. An isolated rerun
of `company-skills.test.ts` and `company-skills-service.test.ts`
reproduced 11 failures because macOS resolved `/var/...` paths as
`/private/var/...`. The changed adapter suites pass independently.
## Risks
- This change deliberately makes the operational skill non-removable for
skill-capable legacy local adapters.
- Existing agents receive the skill on their next list, sync, or run
boundary. No database migration is required.
- The resolver does not create a skill when the runtime inventory does
not contain the canonical entry.
- Hermes aborts a run if another installation occupies the required
operational skill target.
- Hermes removes only an undesired Paperclip-owned symlink that still
points to the known Paperclip source.
- The native runner does not receive the legacy default.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters restore sandbox work into project workspaces after a
run
> - The restore lock used the target workspace parent, which can reject
writes
> - The teardown then hid restore errors, so a run could report success
with lost work
> - This pull request moves the lock into an instance-scoped root and
reports safe restore failure codes
> - The benefit is reliable restore coordination and visible failure
evidence without changing run success semantics
## Linked Issues or Issue Description
Refs: #10914
## What Changed
- Move the workspace-restore merge lock into a private, instance-scoped
root.
- Derive the lock key from the canonical target path with SHA-256.
- Resolve the lock root from the caller environment and reject unsafe
root types.
- Classify restore failures with three allowlisted codes.
- Add the failure code to run result JSON without exposing a host path
or process identifier.
- Keep restore failure fail-open for the run exit code and run status.
## Verification
- Run `npx vitest run
packages/adapter-utils/src/workspace-restore-merge.test.ts`.
- Run `npx vitest run
packages/adapter-utils/src/acpx-engine/run-fault-matrix.test.ts`.
- Run the four Codex credential suites.
- Confirm the branch includes the current `master` commit and no manual
lockfile edit.
- Confirm all pull request checks and the Greptile review reach a
terminal green state.
## Risks
- The lock path changes for workspace restore and removes the
sibling-directory fallback.
- A misconfigured or inaccessible instance home can still stop lock
setup.
- Restore remains fail-open, so callers must inspect the result evidence
when a restore fails.
## Model Used
OpenAI GPT-5. The model used tool calls and code execution to validate
and route an author-provided change. The implementing engineer authored
the code.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Sandbox adapters stage project files before an agent starts.
> - Referenced projects ignored Git-ignored paths and copied large local
directories.
> - This behavior increased staging time and disk use, and it differed
from anchor workspaces.
> - This pull request resolves Git-ignored paths once and shares that
result across all referenced-project consumers.
> - The benefit is smaller, faster, and consistent project staging.
## Linked Issues or Issue Description
No public GitHub issue exists for this bug.
**What happened?**
Referenced-project staging copied Git-ignored paths, except for a fixed
list of heavy directory names. A large repository therefore used much
more time and disk space than the same repository in an anchor
workspace.
**Expected behavior**
Referenced-project staging should exclude the same Git-ignored paths
that the workspace staging path excludes.
**Steps to reproduce**
1. Create a referenced project with a large Git-ignored directory.
2. Start a sandbox or SSH run that stages the referenced project.
3. Observe that the ignored directory enters the staged content.
**Paperclip version or commit**
Commit `9964b034bbff24e700c8eccf5a8b1fc3daa44bf2`.
**Deployment mode**
Built from source.
## What Changed
- Resolve each referenced project's Git-ignored paths once before
staging.
- Carry the resolved paths as a required field on
`SandboxAdditionalSource`.
- Reuse the resolved paths in sandbox staging, SSH staging, and
content-signature code.
- Harden the read-only Git helper with a bounded process, a reduced
environment, and disabled system and global configuration.
- Fail closed on Git errors, timeouts, and invalid path relations.
- Escape tar glob metacharacters in ignore-derived exclude entries.
- Add and update unit tests for the resolver and its three consumers.
## Verification
- `pnpm vitest run --config packages/adapter-utils/vitest.config.ts`
passes 266 tests locally.
- `pnpm exec tsc --noEmit -p packages/adapter-utils/tsconfig.json`
passes locally.
- CI must pass on this pull request.
- Greptile must report 5/5 with no unresolved comments before merge.
## Risks
- A Git error or timeout now prevents staging for the affected
referenced project.
- The resolver uses a bounded read-only Git process and fails closed by
design.
- The change stays inside `packages/adapter-utils` and does not change
the database schema.
## Model Used
Claude Sonnet 5 (Anthropic) assisted the implementation with code
execution and tool use. The exact context window and reasoning mode are
not recorded.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Runtime skill listing materializes each company skill's files before
handing them to the agent's adapter
> - A materialization failure was swallowed with catch-to-null, and the
skill silently vanished from the runtime while the library still showed
it installed
> - Operators saw "installed", agents saw nothing, and nobody saw the
cause; on claude-local a missing desired skill could even crash the
prompt-bundle hasher
> - This pull request turns both failure paths into structured "missing"
entries with the real error and makes every adapter skip unmountable
entries explicitly
> - The benefit is that a broken skill shows up as broken, with its
cause, instead of not existing
## Linked Issues or Issue Description
**What happened?**
A company skill whose runtime files fail to materialize (deleted source,
missing stored SKILL.md copy, failed version snapshot) disappears from
`listRuntimeSkillEntries` with no trace. Agent skill snapshots report a
generic "not available" with no cause. On claude-local, a desired skill
whose source path does not exist reaches the prompt-bundle hasher, whose
`fs.lstat` throws and can fail the whole run.
**Expected behavior**
The skill appears with `sourceStatus: "missing"` and a `missingDetail`
carrying the underlying error, snapshots and the UI show it as broken,
and adapters skip it at mount time with a logged warning instead of
crashing or dangling-symlinking.
**Steps to reproduce**
Install a local-path skill referenced by an agent, delete its source
directory contents so the stored SKILL.md copy cannot be recovered, and
start a run: before this change the skill vanishes from the runtime set
silently; on claude-local a pinned-but-unmaterializable version can fail
bundle preparation.
## What Changed
- `server/src/services/company-skills.ts` `resolveRuntimeSkillSource`:
both `.catch(() => null)` sites (version snapshot, runtime
materialization) now return the structured `{status: "missing", source,
detail}` shape the deliberate missing branch already used, with the
underlying error message in `detail`.
- `packages/adapter-utils/src/server-utils.ts`:
`isPaperclipSkillSourceMissing` is exported with a doc comment.
- `packages/adapters/claude-local/src/server/execute.ts`: missing
desired skills are filtered out of the prompt bundle and each one logs a
`[paperclip] Warning` with its detail to the run output.
- `cursor-local`, `gemini-local`, `kimi-local`, `opencode-local`,
`pi-local` `execute.ts`: mount loops (and the cursor/gemini injection
calls) skip missing entries instead of symlinking a nonexistent path.
## Verification
- `cd server && npx vitest run
src/__tests__/company-skills-service.test.ts` — new test pins the
missing-with-cause entry for a failed materialization. Nine pre-existing
project-workspace tests in this file fail on my machine at clean
`master` too (environment-specific); their count is unchanged by this
PR.
- `cd server && npx vitest run
src/__tests__/heartbeat-runtime-skills.test.ts
src/__tests__/claude-local-skill-sync.test.ts
src/__tests__/cursor-local-skill-sync.test.ts
src/__tests__/cursor-local-skill-injection.test.ts
src/__tests__/gemini-local-skill-sync.test.ts` — 12 tests pass.
- `cd packages/adapters/claude-local && npx vitest run` — 244 passed, 1
skipped.
- `pnpm run typecheck` clean in server, adapter-utils, and all six
touched adapters.
## Risks
- Runtime skill entry lists grow by the previously dropped entries (now
flagged missing). All shipped consumers either intersect with desired
sets, already handle `sourceStatus: "missing"`, or now skip missing
entries at mount time. The snapshot layer already understood the missing
shape via the `materializeMissing: false` path, so downstream contracts
are unchanged.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter utilities provide sandbox transport paths for agent
execution
> - The retired `duplex_v1` path remains in host, gateway, and test code
after `http2_v1` replaced it
> - Retired transport code adds maintenance cost and leaves an unsafe
fallback for unknown gateway modes
> - This pull request removes the retired path, moves shared `http2_v1`
contracts to a leaf module, and closes mode dispatch to a fixed
allowlist
> - The benefit is a smaller transport surface and explicit failure for
unsupported modes
## Linked Issues or Issue Description
Refs #12120
The `http2_v1` transport replaced `duplex_v1`, but the retired broker,
gateway, constants, and tests remain in the adapter utilities. An
unknown bridge mode can also fall through to the queue gateway when a
queue directory exists. This change removes the retired code and rejects
unsupported modes before gateway selection.
## What Changed
- Delete the host `duplex_v1` broker and its transport-only tests.
- Delete the in-sandbox duplex gateway and retired mode constants.
- Move shared `http2_v1` symbols into `bridge-transport-contract.ts`.
- Update the remaining importers and repair their focused tests.
- Validate bridge modes against `http2_v1` and `queue_v1` before queue
lookup.
- Keep `queue_v1`, `duplex-frame-codec.ts`, and duplex telemetry
dimensions unchanged.
## Verification
- [x] `npx tsc --noEmit -p packages/adapter-utils` passes.
- [x] `npx vitest run packages/adapter-utils/src` passes: 48 files and
968 tests pass, with 4 pre-existing platform skips.
- [x] Full CI is green on this pull request.
- [x] Greptile review is complete and every finding is resolved.
## Risks
The change removes an internal transport that no host path selects. The
main risk is an overlooked import or test dependency. Targeted typecheck
and tests cover the adapter utility package. Full CI must confirm
workspace-wide compatibility.
## Model Used

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip records first-party events, OpenTelemetry data, and local
run-log events
> - The code and documents used one term for these three data paths
> - This naming made the required review level unclear
> - This pull request names each data path in the module names,
documents, and code comments
> - The benefit is a clear review rule without a runtime change
## Linked Issues or Issue Description
**Issue type**
Unclear or confusing.
**Where is the issue?**
`packages/shared/src/telemetry/README.md`, `doc/observability.md`,
`doc/run-log-events.md`, and the duplex instrumentation modules.
**What's wrong?**
The repository used Telemetry for first-party events, OpenTelemetry
data, and local run-log events. This usage made the data path and review
level unclear.
**Suggested fix**
Use Telemetry only for Paperclip first-party events. Use Observability
for OpenTelemetry data. Use the run log for rows in
`heartbeat_run_events`.
Related public pull requests: #8476 and #9672.
## What Changed
- Rename the duplex instrumentation modules and identifiers from
`Telemetry` to `Observability`.
- Move the Observability and run-log contracts out of the Telemetry
README.
- Add `doc/observability.md` and `doc/run-log-events.md` as the
canonical documents.
- Add a file-path review rule to `AGENTS.md`.
- Correct the remaining code comments that name the wrong data path.
- Keep all event names, payloads, database records, spans, configuration
keys, environment variables, and runtime paths unchanged.
## Verification
- `npx vitest run packages/shared/src/telemetry/readme-contract.test.ts`
passes.
- `npx vitest run packages/adapter-utils/src/published-exports.test.ts`
passes.
- `npx vitest run
packages/adapter-utils/src/acpx-engine/startup-timing.test.ts` passes
with 42 tests.
- `pnpm --filter @paperclipai/adapter-utils typecheck` passes.
- `pnpm --filter server typecheck` passes.
- The old module name does not remain in TypeScript or JSON files,
except for the intentional publication guard.
- CI and Greptile checks remain pending after PR creation.
## Risks
- The old duplex module subpath no longer has a compatibility shim. The
board accepted this intentional hard break.
- The new duplex module subpath stays blocked from package publication.
- The change has no runtime effect. The main risk is an incorrect
document or module reference.

OpenAI GPT-5 Codex, exact model ID `gpt-5`, with tool use and code
review support.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use a duplex bridge to send requests and responses
across an isolated boundary
> - The bridge held each request body and response body in memory on
both ends
> - Large bodies can exhaust memory and reduce the safe size of adapter
traffic
> - This pull request sends receive-side bodies as sequenced chunks and
spills large bodies to disk
> - The benefit is bounded memory use with strict size, order, and
cleanup checks
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The adapter-utils duplex bridge transports request and response bodies
across the sandbox boundary.
**Current behavior**
The bridge stores each complete body in memory on both ends of the
duplex channel.
**Proposed behavior**
The bridge sends body chunks with sequence checks. The receive side
keeps bodies up to 1 MiB in memory and spills larger bodies to a
temporary file.
**Reason and benefit**
This change reduces memory pressure and keeps malformed or oversized
input on a terminal error path.
**Breaking changes**
The duplex frame version changes to version 2. The request and response
envelopes now carry bodyByteCount, and body_chunk frames carry the body
data.
## What Changed
- Add version 2 body_chunk frames with 256 KiB raw slices encoded as
canonical base64 text.
- Add receive-side memory and spill reassembly with per-channel disk and
file limits.
- Reject malformed, reordered, oversized, truncated, and non-canonical
body chunks.
- Stream reassembled request bodies to the host forward handler with a
web stream and half-duplex request.
- Remove spill files on success, failure, channel death, and startup
cleanup.
## Verification
- Run the adapter-utils type-check.
- Run the adapter-utils duplex test suite.
- Run all pull request checks.
- Run the Greptile review and confirm a 5/5 score with no open findings.
## Risks
The wire format changes from version 1 to version 2. Older bridge peers
cannot use this protocol. The receive path adds temporary file
operations and cleanup paths. The implementation fails closed when a
body violates size or sequence rules.
## Model Used
OpenAI GPT-5 Codex, tool-enabled coding agent. The exact context-window
size and reasoning mode are not exposed by the runtime.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip runs agents through adapter execution lanes
> - Duplex adapters can lose their control channel before a process
completes
> - The ACP lane already fails closed, but the CLI lane can report false
success
> - This pull request applies the same completion rule to the CLI lane
and shares the loss code
> - The benefit is consistent failure reporting when a duplex channel
closes during a run
## Linked Issues or Issue Description
**What happened?**
A CLI-lane duplex run can lose its control channel before clean process
completion. The run can then report `succeeded` with exit code 0 and no
error code.
**Expected behavior**
The execution target must fail closed when the channel dies before clean
completion. It must return exit code 1, the typed `duplex_channel_lost`
error code, and a short stderr note.
**Steps to reproduce**
1. Start a duplex adapter run through the CLI execution lane.
2. Close the duplex control channel before the process completes
cleanly.
3. Inspect the run result and error code.
**Paperclip version or commit**
Commit `5e01523d4eb6df4a20a0bddd05374c9c42225203`.
**Deployment mode**
Built from source.
**Installation method**
Built from source with pnpm.
**Agent adapter(s) involved**
Claude Code, Codex, Cursor, Gemini, Kimi, OpenCode, and Pi local
adapters.
**Database mode**
Not database-related.
## What Changed
- Add an optional `errorCode` field to `RunProcessResult`.
- Add a one-read completion seam to the execution target process
options.
- Fail closed when a duplex channel dies before clean process
completion.
- Add `settleRunDisposition()` to atomically read and mark orderly
completion.
- Share the typed duplex loss error code across the ACP and CLI lanes.
- Mark non-success terminal results as orderly completion before
teardown.
- Wire the seam through the seven duplex adapters.
- Add regression tests for channel loss, clean completion, and non-clean
terminal results.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts` — 118
passed.
- `npx vitest run packages/adapter-utils/src/acpx-engine/execute.test.ts
-t "sandbox duplex run-disposition seam"` — 4 passed.
- The author confirmed a clean type-check for
`@paperclipai/adapter-utils` and the seven duplex adapter packages.
- Pre-existing environment failures remain outside this change. They
include `EACCES mkdir '/srv/paperclip'` and remote file-size setup
failures.
## Risks
The change alters terminal status for CLI duplex runs that lose control
before clean completion. The typed error code and stderr note keep the
failure visible. The broker marks failed, cancelled, and timed-out
results as orderly completion to prevent false loss events during
teardown.
## Model Used

GPT-5 context window. The model assisted with the implementation and
test work.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Sandbox adapters provide controlled execution for untrusted provider
environments.
> - The sandbox channel needs one persistent duplex transport with
strict host control.
> - The transport must remain off unless the instance setting and
provider capability both allow it.
> - The host must detect loss, bound resource use, and expose only safe
telemetry.
> - This pull request adds the broker, gated selection, kill-switch
wiring, fixed observability, and real-process proof.
> - The benefit is safer sandbox execution with bounded failure behavior
and inspectable transport results.
## Linked Issues or Issue Description
No public issue exists for this change. The related pull requests are
#11738 and #11750.
**Problem or motivation**
The sandbox duplex channel needs a host-controlled broker, strict
transport gates, bounded provider input, and safe loss telemetry.
Without these controls, a provider can cause replay, resource growth,
unsafe endpoint selection, or data exposure through telemetry.
**Proposed solution**
Add a host broker with nested time limits, request limits, one-shot
loss, and per-id deduplication. Select duplex transport only when the
instance setting and provider capability both equal true. Assign the
endpoint and nonce on the host. Reject invalid readiness data and use
the file bridge on failure. Add fixed redacted telemetry and a
real-process end-to-end test harness.
**Alternatives considered**
Keep the file bridge as the only transport. This avoids new channel
behavior but does not provide persistent duplex operation for supported
sandbox providers.
**Roadmap alignment**
This change supports the Cloud / Sandbox agents section in ROADMAP.md.
## What Changed
- Add the duplex bridge broker with bounded forward, response, and
gateway wait budgets.
- Bound concurrent requests, lifetime requests, and request-id bytes
before retention or forwarding.
- Select duplex transport only when both required gates are true.
- Assign the loopback port and nonce on the host and enforce a
liveness-only READY frame.
- Fall back to the file bridge after invalid readiness, contamination,
bind failure, or timeout.
- Carry the kill switch through the server, acpx engine, and six local
adapters.
- Add fixed, redacted duplex telemetry with a provider allowlist.
- Add a real-process end-to-end harness for readiness, round trips,
loss, and teardown.
- Add regression coverage for limits, loss, UTF-8 splits, concurrency,
and telemetry dimensions.
## Verification
- Adapter-utils, server, and Daytona typechecks pass locally.
- Adapter-utils tests pass, including the codec, broker,
execution-target sandbox, and real-process harness.
- Server kill-switch tests pass.
- Live Daytona tests pass with the required provider key and skip
without that key.
- The root pnpm-lock.yaml file has no diff.
- The branch contains ten commits after origin/master.
## Risks
- Duplex transport remains disabled unless both gates equal true.
- A provider remains an untrusted boundary and needs least-privilege
credentials and quotas.
- The server telemetry recorder stays deferred; the default recorder
does nothing.
- A provider that pre-binds the host port causes a fail-closed fallback
to the file bridge.
- The change adds no database migration and changes no root lockfile.
## Model Used
OpenAI GPT-5, exact model family GPT-5, large context window, reasoning,
and tool use. The model assisted with Git handoff validation and PR
preparation. The implementation commits came from the engineering
worktree.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Managed deployments provision a platform-managed default environment
for agent runs; the UI shows this environment in selectors, the agent
form, run details, and the environments page
> - Those surfaces append the raw driver key to the environment name, so
users see labels like "Paperclip Computer (sandbox)", "Paperclip
Computer · sandbox", and fallback copy such as "Managed sandbox" and
"The sandbox has no ready authentication"
> - "sandbox" is infrastructure vocabulary, not the product name of the
environment; showing it next to the managed environment's name is
confusing and off-brand
> - This pull request renders platform-managed environments by name
alone and rewords the sandbox-phrased copy, while user-created
environments keep the driver suffix so mixed lists stay distinguishable
> - The benefit is that the default environment reads as one clear
product name everywhere, and self-hosted users lose nothing: their own
environments still show the driver
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Display of the platform-managed default environment across the UI.
**Subsystem affected**
UI (environment selectors, agent config form, environments page, agents
page, run details) and the claude-local/codex-local adapter auth checks.
**Current behavior**
The agent form labels the inherited default environment as "Name
(sandbox)". Environment selectors and the environments list render "Name
· sandbox". The agents page describes the environment as "<provider>
sandbox provider". The agent form's fallback label is "Managed sandbox".
Adapter auth checks say "The sandbox has no ready authentication for
this adapter."
**Proposed behavior**
Platform-managed environment rows (`metadata.managedByPaperclip`) render
their name alone. The fallback label is "Paperclip Computer". The agents
page describes managed environments as "Managed by Paperclip". Run
details omit the driver suffix for sandbox-driver environments (the
adjacent Provider entry already identifies the mechanism). Adapter auth
checks say "This environment has no ready authentication for this
adapter."
**Reason and benefit**
The managed environment carries a product name. Appending the raw driver
key ("sandbox") to it is noise and contradicts the product naming.
User-created environments keep the driver suffix, so mixed lists stay
distinguishable.
**Breaking changes**
None. Message text of the auth check is not read programmatically; the
UI keys off `ADAPTER_AUTH_MISSING_CHECK_CODE`. Rows without the managed
marker render exactly as before.
## What Changed
- New `environmentDisplayLabel` helper in
`ui/src/lib/managed-sandbox-environment.ts`: managed rows → name alone;
other rows → "Name · driver".
- `AgentConfigForm`: inherited-default label uses the helper; fallback
copy "Managed sandbox" → "Paperclip Computer"; environment options use
the helper.
- `ProjectProperties`, `CompanyEnvironments`: environment selector
options use the helper; the environments-list row hides the driver
suffix on managed rows; the managed detail page's fallback description
no longer says "sandbox".
- `Agents` page: managed environments are described as "Managed by
Paperclip" instead of "<provider> sandbox provider".
- `CommentThread` run details: the driver suffix is omitted for
sandbox-driver environments.
- claude-local and codex-local adapters: auth-missing check message/hint
reworded from "sandbox" to "environment" (ACP and environment-test
paths); claude-local probe/effort/login hints reworded the same way.
- Run status lines: "Syncing workspace to sandbox", "Exporting git
changes from sandbox", "Starting adapter in sandbox", and friends now
say "environment"; "Finalizing sandbox workspace" → "Finalizing
workspace". Templated transfer-progress lines map the `sandbox`
transport key to "environment" for display (`runtime-progress.ts`).
- Agent form sign-in panel: "Sign in to the sandbox" → "Sign in to the
environment"; "Authenticated. The sandbox has credentials now." → "…The
environment has credentials now."
- Feature catalog + instance settings card: "Managed Sandbox Only" →
"Managed Environment Only" (setting key unchanged; the card keeps its
alphabetical slot).
- Server agents routes: execution-target failure and test-identity copy
no longer say "sandbox"; workspace-mode label "Cloud sandbox" → "Cloud
environment".
- Tests: new `environmentDisplayLabel` unit cases; new `AgentConfigForm`
render case asserting the managed default renders without "(sandbox)" or
"· sandbox"; status-line assertions updated across adapter-utils, server
heartbeat/live-run, and UI chat suites.
## Verification
- `pnpm --filter @paperclipai/ui typecheck` — clean.
- `pnpm --filter @paperclipai/adapter-claude-local typecheck` and
`--filter @paperclipai/adapter-codex-local typecheck` — clean.
- `vitest run` for `managed-sandbox-environment.test.ts`,
`AgentConfigForm.render.test.tsx`, `CompanyEnvironments.test.tsx`,
`Agents.test.tsx`, `CommentThread.test.tsx`, `NewAgent.test.tsx` — all
green (118 tests across the two runs).
## Risks
Low risk. Cosmetic label changes only; no data or API changes. Rows
without `metadata.managedByPaperclip` render exactly as before, so
self-hosted deployments with their own environments see no change. The
only self-hosted-visible wording changes are the adapter auth-check
message and the driver suffix omission on sandbox-driver rows in run
details.
## Model Used
- Claude (Anthropic) — claude-fable-5 (Claude Fable 5), Claude Code CLI,
extended thinking, tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The heartbeat system records agent runs and can add a run summary to
an issue.
> - The ACPX engine receives output text and internal thought text as
separate streams.
> - The default summary strategy joined both streams and could publish
internal text in an issue comment.
> - Paperclip already has final-output segmentation for run summaries.
> - This pull request makes final-output-only summaries mandatory and
removes the configuration bypass.
> - The benefit is that automatic issue comments contain the intended
final message instead of internal execution text.
## Linked Issues or Issue Description
Refs #11761
**What happened?**
The ACPX engine used the full summary strategy when an adapter did not
set `summaryStrategy`. That strategy joined all text deltas, including
thought-stream text and intermediate narration. The heartbeat finalizer
could then store that summary as an issue comment.
**Expected behavior**
An automatic issue comment must use only the final output segment.
Configuration must not allow thought-stream text or intermediate
narration into that summary.
**Steps to reproduce**
1. Run an ACPX adapter without a configured `summaryStrategy`.
2. Emit an output delta, a thought delta, a tool call, and a final
output delta.
3. Read the generated run summary.
4. Observe that the old default included all text deltas.
**Paperclip version or commit**
`54b8bec44417511c623999613f9f1006f8af0517`
**Deployment mode**
Built from source with a local ACPX adapter.
## What Changed
- Limit ACPX run summaries to the final non-empty output segment.
- Ignore the legacy full-summary setting so configuration cannot bypass
containment.
- Update regression tests for the safe default and an attempted unsafe
override.
## Verification
- Observed the new guard fail before the implementation change because
the summary contained thought text.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "defaults run
summaries to the final output segment without thought text|does not
allow configuration to include thought text in run summaries"`. Result:
2 passed.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts`. Result: 130
passed.
- Ran `pnpm --filter @paperclipai/adapter-utils typecheck`. Result:
passed.
## Risks
- Run summaries are shorter for adapters that relied on full text
aggregation.
- The old `summaryStrategy: "full"` setting no longer changes summary
behavior. This is an intentional containment change.
- The change does not alter run logs or tool events. It changes only the
summary selected for downstream use.
> This is a focused security and privacy bug fix. It does not add
roadmap scope.
## Model Used
- OpenAI Codex on the GPT-5 family. The runtime did not expose the exact
model ID or context-window size. Reasoning, tool use, terminal
execution, and code editing were enabled.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local agent adapters (`claude_local`, `gemini_local`, `grok_local`,
…) are the integration surface that lets Paperclip run coding CLIs on
the host machine
> - The Kimi Code CLI (`kimi`, Moonshot AI) has a documented
non-interactive mode, `kimi -p --output-format stream-json` with session
resume via `kimi -r`, but Paperclip has no built-in adapter for it
> - So Kimi users (especially Kimi membership / OAuth subscribers)
cannot onboard their CLI to Paperclip agent teams
> - This pull request adds a complete built-in `kimi_local` adapter
(both execution engines, session management, instructions + skills
delivery, thinking-effort control, environment test, UI and CLI modules,
docs) following the established `gemini_local`/`grok_local` package
pattern
> - Kimi Code ships an ACP server (`kimi acp`), so the adapter runs on
Paperclip's shared acpx engine by default (streaming transcript with
live tool status, like `claude_local`/`gemini_local`) and falls back to
a headless CLI lane (`kimi -p --output-format stream-json`) when ACP
prerequisites are unavailable
> - The benefit is that Kimi Code becomes a first-class Paperclip agent
lane: selectable in the UI, resumable across heartbeats, with the same
operating context (instruction bundle, skills, effort) and streaming
transcript the other local adapters get
## Linked Issues or Issue Description
- Supersedes #9880 (same branch; expanded from the CLI-only lane into a
complete adapter with the default ACP engine lane, control-plane skill
install, and live transcript wiring)
- Refs #9879 (adapter request for Kimi Code CLI, filed with this PR)
- Refs #163 (original Kimi support request)
Duplicate/related prior PRs, per the dedup search (both appear stale: no
updates or maintainer review since May 2026, and both target an older
Kimi CLI interface; calling them out for reviewer context per
CONTRIBUTING.md):
- Refs #6276 (`feat: add kimi-local adapter`): targets an older
array-based content format (`{type: think}`/`{type: text}` blocks), not
the current documented stream-json schema
- Refs #5202 (`feat(adapter): add Kimi CLI local adapter with Wire
protocol support`): builds on a `--wire` JSON-RPC interface that current
Kimi Code CLI (0.27.0) no longer documents; the current documented
headless interface is `-p --output-format stream-json`
This PR is a fresh implementation against current master and the
currently documented/verified Kimi CLI behavior (see Verification).
Happy to fold in anything useful from the earlier attempts if a reviewer
prefers.
## What Changed
- **New adapter package** `packages/adapters/kimi-local`
(`@paperclipai/adapter-kimi-local`), modeled on
`gemini-local`/`grok-local`:
- `src/server/execute.ts`: spawns `kimi -p <prompt> --output-format
stream-json` (argv array, no shell), `-m <model>` only when configured,
`-r <sessionId>` when the stored session cwd matches the run cwd,
automatic fresh-session retry on unrecoverable-session errors,
headless-safe env (`CI=1`, `NO_COLOR=1`, `KIMI_CODE_NO_AUTO_UPDATE=1`,
`TERM=dumb`; user-configured values win), full remote (ssh/sandbox)
execution lane with runtime install via `@moonshot-ai/kimi-code`
- **Instruction bundle delivery**: the prompt path directive now names
the sibling instruction files (`./HEARTBEAT.md`, `./SOUL.md`,
`./TOOLS.md`) alongside the prepended entry file, and local runs pass
`--add-dir <instructions-dir>` so Kimi can actually open them (matching
`claude_local`). Without this, only the entry file reached Kimi and
agents improvised the operating workflow that `HEARTBEAT.md` documents
- **Thinking effort**: a configured `effort` is forwarded as the
`KIMI_MODEL_THINKING_EFFORT` operational override (Kimi has no
per-invocation effort flag). It is only sent for models that advertise
`support_efforts` (currently `kimi-code/k3`) to avoid provider
rejections, and `medium` maps to `high` since Kimi has no medium tier
(`low`/`high`/`max` pass through)
- **Skills delivery**: desired Paperclip skills are delivered via Kimi's
`--skills-dir` flag from a dedicated per-run directory (a local
snapshot, or the synced snapshot on remote targets), so skills load
reliably and in isolation. Paperclip never overwrites the shared
`$KIMI_CODE_HOME/skills` home, so skills installed by the operator or
other agents are left intact. `--skills-dir` is only passed when at
least one skill is desired, so unconfigured agents keep Kimi's default
skill discovery
- **Live run status**: the adapter now forwards each streamed
stream-json line to `onEvent` (assistant `content` as an assistant
snippet, `tool_calls` as tool-name events), which drives the
issue-thread activity indicator (`currentToolName` /
`lastAssistantSnippet` / `lastEventAt`). Previously the adapter only
wrote the raw run log, so the issue thread showed a stale "no output for
N s" line with no tool or reasoning context while Kimi worked. Tool
results are omitted so the last meaningful "Using X" / snippet is not
overwritten by a generic label
- `src/server/parse.ts`: parses the verified Kimi stream-json event
shapes (`assistant` text, `assistant.tool_calls` with JSON-string
arguments, `tool` results, trailing `meta.session.resume_hint` for
session-id capture) plus failure classifiers (`kimi_auth_required`,
transient network, unrecoverable session). A signaled exit (null exit
code, not a timeout) is now reported as a failure rather than coalesced
to success, and the error message names the terminating signal
- `src/server/skills.ts`: lists/syncs Paperclip skills for the adapter's
skill-management surface
- `src/server/test.ts`: environment test covering CLI resolution + `kimi
--version`, cwd check, auth detection (OAuth credential dirs, keyed
`[providers.*]` in config.toml, or the `KIMI_MODEL_NAME` +
`KIMI_MODEL_API_KEY` env pair), and a live hello probe
- `src/ui/` (stdout-line parser for transcripts, config builder) and
`src/cli/` (stream event formatter) modules
- Root metadata: three managed model aliases
(`kimi-code/kimi-for-coding`, `kimi-code/kimi-for-coding-highspeed`,
`kimi-code/k3`), effort-capable-model metadata (`EFFORT_CAPABLE_MODELS`,
effort mapping helpers), `agentConfigurationDoc`
- Tests: 101 tests across parse, execute (args building, resume gating,
retry, auth error code, timeout, signaled-exit failure, effort
forwarding/gating/mapping, `--add-dir` instructions directive,
`--skills-dir` gating, `onEvent` runtime-event forwarding), ACP engine
(engine resolution, acpx config build, node-version gate), ACP
transcript delegation, environment test, UI parse/build-config
- **ACP engine lane (default)** (`src/server/acp.ts` + shared
`adapter-utils/acpx-engine`): Kimi Code ships an ACP server (`kimi
acp`), so `kimi_local` now runs on Paperclip's shared acpx engine by
default, matching `claude_local`/`codex_local`/`gemini_local`. The
issue-thread transcript streams live (assistant text deltas, tool calls
with a `pending`->`completed` status lifecycle) instead of the CLI
lane's bursty complete-message output. Registered `kimi_local -> "kimi"`
in `ACPX_ADAPTER_AGENT_IDS` and resolved the built-in agent command to
`kimi acp`; `execute.ts` dispatches to the ACP executor first with an
automatic CLI fallback when ACP prerequisites fail (`engine=acp`
requires ACP, `engine=cli` pins the headless lane); `index.ts` falls
back to the shared acpx session codec; the UI/CLI delegate `acpx.*`
events to the shared acpx transcript parser and event formatter. The
headless CLI lane (above) remains as the fallback
- **Registration** (one entry each, mirroring existing adapters): server
adapter registry + `BUILTIN_ADAPTER_TYPES`, `AGENT_ADAPTER_TYPES`
(shared), UI adapter registry + display registry (`Kimi Code`, Moon
icon) + capabilities defaults, CLI adapter registry, `Dockerfile`
(package copy + `npm install --global @moonshot-ai/kimi-code@latest`),
`vitest.config.ts` workspace, `scripts/release-package-manifest.json`
- **Behavioral sets** mirroring `gemini_local` (Kimi resumes sessions
the same way): `GIT_SENSITIVE_LOCAL_ADAPTER_TYPES`,
`SESSIONED_LOCAL_ADAPTERS` (heartbeat + recovery),
`REMOTE_MANAGED_ADAPTERS`, ssh/sandbox execution-target allow-lists,
`ADAPTER_DEFAULT_RULES_BY_TYPE` (`timeoutSec: 0`, `graceSec: 15`), and
`LEGACY_SESSIONED_ADAPTER_TYPES` + `ADAPTER_SESSION_MANAGEMENT` in
adapter-utils
- **UI touch-points**: New Agent default-model branch, AgentConfigForm
command map (`kimi_local: "kimi"`) + model defaults + a Kimi-specific
thinking-effort option list (`Low`/`High`/`Max`, reflecting Kimi's tiers
rather than borrowing Claude's), OnboardingWizard (command map, model
default, `kimi login` / `KIMI_MODEL_NAME + KIMI_MODEL_API_KEY` auth
hints, manual-debug command line), InviteLanding enabled adapters
- **Control-plane skill install** (`cli/src/commands/client/agent.ts`):
`paperclipai agent local-cli` seeded the Paperclip control-plane skills
into `~/.codex/skills` and `~/.claude/skills` so Codex/Claude agents
auto-discover the API reference every run. Kimi had no equivalent
target, so `kimi_local` agents began each session without the
control-plane skill and rediscovered routes (e.g. the company-scoped
`POST /api/companies/{companyId}/issues`) by trial and error. Added
`~/.kimi-code/skills` (honoring `KIMI_CODE_HOME`) as a third install
target for parity. Independent of the per-run `--skills-dir` delivery,
which only applies to explicitly configured skills.
- **Docs**: `docs/adapters/kimi-local.md` (prerequisites, auth options,
config fields including `effort`, session resume, instruction bundle,
skills delivery, control-plane skill install) + a row in
`docs/adapters/overview.md`
Out of scope (deliberately): model profiles, built-in agent
`allowedAdapterTypes` additions.
## Verification\n\nCurrent-master rebase verification (OpenAI Codex,
2026-08-03): 13 focused files / 231 tests pass; adapter-utils, server,
UI, CLI, and Kimi adapter typechecks pass; full repository build and UI
token gates pass. The branch is conflict-free against master at head
`1249df117c5e12e5771b9a570a6340866450619e`.\n\nAutomated (all from repo
root, pnpm 9.15.4, Node 22):
- `vitest run packages/adapters/kimi-local`: 89/89 pass (includes
coverage for the instruction `--add-dir` directive, effort
forwarding/gating/mapping, `--skills-dir` gating, the signaled-exit
failure path, and `onEvent` runtime-event forwarding with cross-chunk
line buffering)
- `vitest run server/src/__tests__/adapter-registry.test.ts
server/src/__tests__/adapter-routes.test.ts
server/src/services/heartbeat-stop-metadata.test.ts
ui/src/adapters/adapter-display-registry.test.ts`: 37/37 pass
- `vitest run cli/src/__tests__/skills.test.ts`: 13/13 pass (the
control-plane skill install target follows the existing Codex/Claude
install path, whose symlink logic is unchanged)
- `vitest run packages/shared`: 307/307 pass; `vitest run
packages/adapter-utils`: pass except one pre-existing, unrelated failure
(`mcp-isolation.integration.test.ts` requires Claude CLI ≥ 2.1.207; host
has 2.1.185, fails identically on unmodified master)
- `pnpm --filter @paperclipai/adapter-kimi-local typecheck|build`, plus
typecheck of `server`, `ui`, `cli`, `adapter-utils`: all clean
- `pnpm install --frozen-lockfile`: passes (the PR diff itself contains
no lockfile changes, per repo policy; verified against a locally
regenerated lockfile)
- `node scripts/check-no-git-push.mjs` and `node
scripts/check-forbidden-tokens.mjs`: pass
- CI note: the `policy` job's release-bootstrap step is expected to stay
red until a maintainer bootstraps the first npm publish of
`@paperclipai/adapter-kimi-local`; see the CI Note for Maintainers
comment. All other contributor-actionable checks are green.
Manual end-to-end (real Kimi CLI 0.27.0, OAuth login, dev server on an
isolated instance):
1. Server `GET /api/adapters` lists `kimi_local` as builtin with correct
capability flags; models endpoint returns the three Kimi models
2. `POST .../adapters/kimi_local/test-environment`: all checks pass,
including a live `kimi -p` hello probe
3. Created a `kimi_local` agent and invoked two heartbeats: run 1
spawned `kimi -p ... --output-format stream-json`, Kimi used its `Read`
tool, produced the expected answer, and the session id was captured from
the `session.resume_hint` meta event; run 2 resumed the **same** Kimi
session (`sessionIdBefore == sessionIdAfter`) via `-r`
4. UI: adapter appears in the New Agent dropdown; selecting it shows the
Kimi command placeholder, the three models, and the Kimi config fields;
the run transcript renders Kimi tool calls via the adapter's stdout
parser
The instruction-bundle, thinking-effort, and `--skills-dir` changes
landed after the manual run above. They are covered by the unit tests
listed under Automated, and the Kimi CLI flags they rely on
(`--add-dir`, `--skills-dir`, `KIMI_MODEL_THINKING_EFFORT`) were
confirmed against the installed Kimi Code CLI 0.27.0 (`kimi --help`,
config-file thinking-effort docs).
Screenshots (assets branch on the fork, not part of the diff):
## Risks
- Low risk to existing behavior: the change is additive, one new
workspace package plus single-entry registrations alongside existing
adapters; no existing adapter code paths are modified.
- The adapter invokes the locally installed `kimi` CLI; like other local
adapters, run behavior depends on the host's Kimi version. The parser is
written against the documented/verified 0.27.0 stream-json schema and
degrades gracefully (malformed lines are skipped, failures surface as
run errors).
- `--skills-dir` overrides Kimi's auto-discovery of user and project
skills for the run. This is intentional (paperclip-managed agents get a
reproducible, isolated skill set), and it is only passed when at least
one Paperclip skill is desired, so unconfigured agents keep default
discovery.
- Thinking effort is only forwarded to models that advertise
`support_efforts` (currently `kimi-code/k3`); `EFFORT_CAPABLE_MODELS`
must be extended when more Kimi models gain support, otherwise a
configured effort is silently ignored for them.
- `Dockerfile` now installs `@moonshot-ai/kimi-code@latest` globally
alongside the other agent CLIs, so image size increases slightly.
- Maintainer action needed for the npm bootstrap gate: the `policy`
job's release-bootstrap step fails until the first npm publish of
`@paperclipai/adapter-kimi-local` (the gate from #5146 that every new
adapter package has passed through). Enrollment with `publishFromCi:
true` is required by the manifest validator (dropping the entry,
`false`, or `private` are all rejected), so this is intentionally left
to a maintainer. Remaining CI lanes are expected to run once it is done.
## Model Used\n\n- **Current-master rebase, conflict adaptation, and
registry-parity coverage:** OpenAI, **GPT-5 Codex** (Codex agent; exact
serving model ID and context-window size were not exposed to the
runtime), with repository, shell, Git, and GitHub tooling. It preserved
Hawik’s commit authorship, reconciled ACPX and environment-capability
changes, added current registry tests, and ran the verification
above.\n- **Adapter implementation and initial review:** Moonshot AI,
**Kimi K3 Coding** (latest), via **Kimi Code CLI v0.27.0**
(`kimi-code/k3` alias, 1M-token context window, thinking mode, agentic
tool use). The CLI agent explored the repo, wrote the adapter
implementation (delegated to a coder sub-agent of the same model), ran
tests, and drafted the first version of this PR body. A second
model-driven review pass (read-only, same model) audited the diff for
security/correctness before submission; its findings (shell-quoting
hardening, auth-detection false positive, session-compaction
registration, test gaps) were fixed and are included.
- **Harness-context fixes and review responses:** Anthropic, **Claude
Opus 4.8** (`claude-opus-4-8`) via Claude Code. Diagnosed from run logs
that Kimi received only the entry instructions file (not the
`HEARTBEAT.md`/`SOUL.md`/`TOOLS.md` bundle) and that `effort` was never
wired, then implemented the instruction `--add-dir` delivery,
`KIMI_MODEL_THINKING_EFFORT` forwarding, and `--skills-dir` skill
delivery, added the accompanying tests and docs, and addressed the
automated review comments (preserving external skills on remote sync,
treating a signaled exit as a failure). Also extended the `paperclipai
agent local-cli` installer to seed the control-plane skills into
`~/.kimi-code/skills` for Codex/Claude parity, wired `onEvent` runtime
events so the issue-thread activity indicator reflects Kimi's tool and
reasoning output live, and built the ACP engine lane (`kimi acp` via the
shared acpx engine, default) so the transcript streams with live tool
status like the other ACP adapters. The Kimi CLI flags, subcommand, and
env var relied on here were verified against the installed Kimi Code CLI
0.27.0.
- All CLI behaviors claimed here (`-p`, `--output-format stream-json`,
`-r` resume, event shapes, `--add-dir`, `--skills-dir`,
`KIMI_MODEL_THINKING_EFFORT`) were verified empirically against the
installed Kimi CLI, not assumed.

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Local agent adapters stream their work through the shared acpx
engine, which every ACP adapter (`claude_local`, `codex_local`,
`gemini_local`, custom ACP) runs on
> - Verbose streaming backends break two shared-engine behaviors: the
auto-posted run summary concatenates every text delta including the
thought stream (a long multi-tool run once auto-posted a ~50k character
monologue as an issue comment), and token-by-token tool-argument
streaming floods the run log with tens of thousands of
placeholder-titled in-progress events per run
> - These fixes were developed inside the `kimi_local` adapter PR, where
Kimi Code's streaming volume (~16,000 text deltas per run vs ~290 for a
comparable Claude run) surfaced both problems
> - Changing this behavior for all adapters at once is a fleet-wide
risk, and hardcoding adapter identities in shared code does not scale to
many adapters (or work at all for externally-shipped plugin adapters) —
so the behaviors become invocation-config parameters that an adapter's
own acpx config builder sets, with defaults preserving today's behavior
byte-for-byte
> - The benefit is that the machinery lands fully tested with zero
behavior change for existing adapters — pin tests prove it — the engine
carries no adapter identities, and any adapter (including `custom_acp`
configs for external backends) opts in declaratively
## Linked Issues or Issue Description
- Refs #9967 — extracted from the `kimi_local` adapter PR and
restructured to be inert by default; the commit preserves the original
author's (@hawikk) authorship.
**Current behavior**
When an acpx-engine run ends without the agent leaving a comment, the
auto-posted summary is every streamed text delta concatenated, thought
stream included. Backends that stream tool arguments emit tens of
thousands of placeholder-titled `in_progress` tool events into the
stored run log, pinning the live activity indicator to a generic "tool
call". There is no mechanism for an adapter to vary either behavior, and
shared code must never branch on adapter identities.
**Proposed behavior**
Two engine invocation-config parameters, read with behavior-preserving
defaults: `summaryStrategy` (`"full"` = existing concatenation, the
default; `"lastOutputSegment"` = segment output at tool starts, exclude
thought stream, post the last non-empty segment) and
`coalescePlaceholderToolUpdates` (`false` = never drop an event, the
default; `true` = coalesce placeholder-titled in-progress updates). An
adapter opts in from its own acpx config builder — the engine has no
per-adapter knowledge, no adapter identity appears anywhere in shared
code, and `custom_acp` agent configs can set the same knobs for external
verbose backends.
**Reason and benefit**
Existing adapters are provably unaffected — new pin tests assert the
default path's summary and tool-event output byte-for-byte, so any
future change that alters behavior for claude/codex/gemini/custom fails
the suite. The verbose-backend handling still lands fully tested,
activated declaratively by the adapter that needs it (the `kimi_local`
adapter PR sets both knobs in its config builder).
## What Changed
- `packages/adapter-utils/src/acpx-engine/execute.ts`: the run
preparation parses `summaryStrategy` and
`coalescePlaceholderToolUpdates` from the invocation config (validated,
defaulted); summary accumulation and `emitRuntimeEvent` branch on the
prepared values. The default path is the pre-existing code
(`textParts.join("")`, no event filtering). `buildAcpxRunSummary` is the
exported last-segment strategy.
- `packages/adapter-utils/src/acpx-engine/execute.test.ts`: a pin test
asserting the default path's exact summary (thought stream included) and
full tool-event stream (placeholder-titled in-progress updates present,
names restored); opt-in tests for each knob; a `buildAcpxRunSummary`
unit test.
- `ui/src/adapters/types.ts`: `UIAdapterModule` gains an optional
`transcriptPresentation` capability — `maxVisibleEntries` (issue-chat
transcript window, default 30) and `liveReasoningView` (`"ticker"`
default; `"scrollLog"` renders live reasoning in a scrollable
auto-following box with one entry per tool call).
- `ui/src/lib/issue-chat-messages.ts` and
`ui/src/components/IssueChatThread.tsx`: shared code resolves the hints
via `findUIAdapter(adapterType)` with today's defaults as fallback — no
adapter identities anywhere. The `scrollLog` rendering component ships
here but is unreachable until an adapter declares it.
- `ui/src/lib/issue-chat-messages.test.ts`: a capability test registers
a synthetic verbose adapter and asserts the wider window; the
pre-existing test keeps pinning the default 30-entry window.
No adapter declares any of this in this PR — every adapter renders and
summarizes exactly as before, and there is no per-adapter data anywhere.
The `kimi_local` adapter PR (#9967, stacked on this branch) is the first
consumer: it declares `transcriptPresentation` in its own UI module and
sets the engine knobs in its own acpx config builder.
## Verification
- Engine suite: 130/130 pass (126 existing + 4 new); chat suites
(`issue-chat-messages`, `IssueChatThread`, `RunChatSurface`): all pass
including the new synthetic-adapter capability test — 237 tests across
the touched surfaces
- The pin tests are the regression guard: the engine test encodes
today's summary text and tool-event sequence for a default-config run,
and the existing 30-entry-window test pins the default transcript
window, so "nothing changed for Claude/Codex users" is an executable
assertion, not a review judgment
- `pnpm --filter @paperclipai/adapter-utils --filter @paperclipai/ui
typecheck`: clean
## Risks
- Low: with no adapter setting the knobs, every code path taken in
production is the existing one. The only behavioral surface is additive
(an unused strategy and an unused filter), exercised by tests.
- The knobs are ordinary invocation-config keys, so a `custom_acp` agent
config can also set them — intended: an external verbose backend gets
the same handling without code changes. Both knobs only affect that
agent's own run summaries and run-log verbosity.
## Model Used
- Original implementation authored in #9967 by @hawikk (models
documented there: Moonshot AI Kimi K3 Coding via Kimi Code CLI 0.27.0,

that authorship.
- Extraction, restructuring into config-declared parameters, pin tests,
and verification: Anthropic, **Claude Fable 5** (`claude-fable-5`) via
Claude Code, with repository, shell, and Git tooling.

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

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

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter runtime starts, turns, settles, and composes ACPX runs
> - Recent lifecycle corrections changed several order and cleanup rules
> - Those rules need regression coverage before the planned engine
refactor
> - This pull request adds characterization suites for the corrected
behavior

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters run ACP sessions and manage runtime, workspace, and
lease resources.
> - Several failure paths left runtime bridges, staged workspaces, or
environment leases active after an error.

## Linked Issues or Issue Description
**What happened?**
ACP runs could leave runtime bridges, staged workspaces, or environment
leases active after failures. Claude and Gemini ACP runs did not restore
the sandbox workspace on teardown. Lease release stopped when one lease
returned an error.
**Expected behavior**
Each ACP failure must return an error result and settle its resources.
Teardown must run each step, release leases independently, and restore
the host workspace when the sandbox ends. Pending cleanup leases must
receive bounded retry attempts.
**Steps to reproduce**
1. Run an ACP session that fails after runtime creation or during turn
preparation.
2. Run an ACP session that fails during a warm hit or staged runtime
handoff.
3. Run lease cleanup with more than one lease when the first release
returns an error.
4. Inspect the result phase, teardown calls, workspace state, and lease
metadata.
5. Run the regression suites listed in the Verification section.
## What Changed
- Settle every ACP failure after runtime creation with an error result
and one sandbox.startup span closure.
- Close the ACP runtime and remove warm entries after every pre-turn
failure.
- Run all teardown steps, record teardown errors, release staging leases
in finally, and prevent duplicate teardown.
- Dispose staged runtimes after seam failures and remove borrowed staged
entries with identity guards.
- Add fail-open workspace sync-back teardown for Claude and Gemini ACP
adapters.
- Isolate lease release errors and add bounded retry sweeps for stranded
pending_cleanup leases.
- Atomically claim pending_cleanup retries and clamp attempt readers to
keep the five-attempt bound.
- Default absent provider reusableLeases values to false and align the
fake provider with its runtime declaration.
- Add regression tests for engine, adapter, server, and shared
environment behavior.
## Verification
- [x] `npx vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` — 124 tests
passed.
- [x] `npx vitest run

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

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

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

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

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Bridge workers keep startup setup separate from long-lived runtime
work
> - The callback bridge must keep queue-directory setup inside the
startup step
> - The long-lived poll loop must run with no active startup step

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

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

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

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

pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` — 89 passed.

- `git diff --exit-code origin/master...HEAD -- pnpm-lock.yaml` —
passed.
- `git diff --exit-code origin/master...HEAD -- .github/workflows` —

## Risks
- Runtime risk is low to moderate. ACPX now awaits process-identity
persistence during child startup.
- ACPX kills the child when persistence fails. This prevents an
unsupervised process, but it makes that heartbeat fail visibly.
- A compatible warm heartbeat reuses the identity of the existing ACP
child. Regression tests verify that identity is persisted before the
next prompt.
- The change updates the vendored ACPX patch. Package installation must
apply that patch.
- There are no schema, migration, public API, UI, workflow, or lockfile
changes.

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

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This change touches server orchestration, sandbox
transport, and observability.
**Problem or motivation**
A run can @-mention another project. Local targets stage each referenced
project and give the agent a path. Remote confined sandboxes dropped the
full referenced set, so the agent could not read those project files or
paths.
**Proposed solution**
Enable referenced-project sync for the confined sandbox transport behind
`PAPERCLIP_MULTI_PROJECT_WORKSPACE_SYNC_REMOTE`, which defaults on. Keep
the SSH transport out of scope and keep it dropping referenced projects.
Repoint each referenced workspace hint at its staged
`project-<projectId>` sandbox directory. Publish
`PAPERCLIP_WORKSPACES_JSON` on the confined sandbox lane. Count each
per-project remote staging failure as a `staging` failure in the
requested-vs-synced metrics.
**Alternatives considered**
Keep the remote path drop-only. That keeps the gap open. Move the change
into SSH too. That expands scope beyond the target transport and adds
risk.
**Roadmap alignment**
No matching item in `ROADMAP.md` showed up in this review.
**Additional context**
The change lands in three commits. The first commit opens the gate for
the confined sandbox transport. The second commit repoints the workspace
hints and publishes the workspace map. The third commit records
per-project staging failure data.
## What Changed
- Opened remote referenced-project sync for the confined sandbox
transport behind `PAPERCLIP_MULTI_PROJECT_WORKSPACE_SYNC_REMOTE`.
- Repointed referenced workspace hints to the staged
`project-<projectId>` sandbox directories and published
`PAPERCLIP_WORKSPACES_JSON`.
- Counted per-project remote staging failures as first-class `staging`
failures in the requested-vs-synced observability.
## Verification
- The pushed ref
`refs/heads/feat/sync-referenced-projects-remote-sandbox` resolves to
the authorized submit SHA.
- `git log --oneline
origin/master..origin/feat/sync-referenced-projects-remote-sandbox`
shows exactly the three expected commits.
- The handoff reports server typecheck clean, adapter-utils typecheck
clean, and the listed unit tests passing.
- The handoff also reports no open review comments and no Greptile score
yet.
## Risks
- The change touches authorization and sandbox path handling, so
regressions could block remote runs or expose the wrong project context.
- The new flag defaults on, so any bug in the remote path affects normal
remote use.
- SSH stays out of scope, so the two transport paths must remain
distinct.
## Model Used
OpenAI GPT-5 via Codex. Tool use enabled. Context window not reported in
this run.

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

## 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.

## Linked Issues or Issue Description
No public issue exists.
Related PR: #10448.
## What Changed
- Thread additional referenced-project sources through the run prepare
path and the runtime layers.
- Stage each referenced project into its own `project-<projectId>`
directory under the runtime root.
- Keep the anchor workspace history and overlay semantics unchanged.
- Fail closed on confinement or sync errors for one project, and keep
the other projects running.
- Keep the path inert by default behind the multi-project workspace-sync
kill-switch.
- No documentation update was needed for this code-only runtime change.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec vitest run

- 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 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

## 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

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 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

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

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 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.

> - 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.

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

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

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