**What existing behavior does this improve?**
The task composer and existing task/subtree pause controls.
**Current behavior**
A paused task can still receive a board message. The pause notice sits
outside the composer, which leaves the send action available.
**Proposed behavior**
Show an amber takeover in both task chat and the classic composer.
Preserve the draft. Require the user to resume the task or the ancestor
subtree before sending. Reject board comment writes through either
supported write route while the pause hold is active.
**Breaking changes**
Board comment writes to a paused task now return HTTP 409. Agent run
reports remain supported during a pause. There is no schema migration.
## What Changed
- Add a shared amber composer takeover with task, subtree, saved draft,
pending, and error states.
- Use effective ancestor pause state in both composer interfaces.
Refresh it after pause events, task updates, and rejected sends.
- Preserve draft text and attachments. Hide editor, send, queued edit,
and pending question controls while paused.
- Check active pause holds before board comment writes can mutate tasks,
store comments, or wake agents.
- Connect the approved Storybook examples to the production component
and update the design and behavior docs.
- Add browser coverage for both composers, draft persistence, resume,
inherited holds, and rejected writes. Update ACP continuation coverage
for the explicit resume requirement.
## Verification
- Passed: `pnpm -r typecheck`.
- Passed: `pnpm build`.
- Passed: `pnpm build-storybook`.
- Passed: `pnpm check:token-gates` and `git diff --check`.
- Passed: focused UI tests (398 tests) and server route tests (127
tests).
- Passed: `pnpm exec playwright test --config
tests/e2e/playwright.config.ts tests/e2e/paused-composer.spec.ts
tests/e2e/acp-stop-continuation.spec.ts` (5 tests).
- Passed: manual browser walkthrough in a disposable local instance.
Pause with a draft, refresh while paused, resume, send, and reopen. The
draft returned, and one message persisted. The amber card and resume
dialog were readable with no clipping.
- Full local `pnpm test:run` did not pass: the general-server stage
recorded 9,072 passing tests, 6 database setup failures from macOS
shared-memory exhaustion, and 4 failed tests. This stopped the script
before its later groups. Latest-head CI runs those groups independently.
- Local follow-up: the Git file-resource load test passed on rerun (4
tests); native finalization migration passed after clearing the
abandoned browser-test database allocation. Building the native debug
fixtures fixed the missing fake provider. The remaining native-session
recovery assertion also reproduces on untouched base commit `87b3e5fc6`
(36 pass, 1 fail on both base and PR). It expects a settled-session
error but receives a semantic-input-digest error.
- The final UI build, UI typecheck, token gates, both thread suites (182
tests), and all five browser tests passed after the queued-action review
fix. All 31 latest-head CI checks passed, including all server,
workspace, browser, build, release, and security gates. Two optional
Storybook jobs were skipped by workflow policy. Greptile reviewed
`32d8fb5f5` at 5/5 with no open findings.
- Review the Paused Composer and Tasks / Execution Controls stories.
Pause a task with a draft, verify the amber card, resume, and verify the
draft can be sent once.
## Risks
- Clients that used board comments to continue paused work must resume
first. The response is an explicit HTTP 409.
- Pause state can change while a page is open. Live updates refresh the
composer, and the server rejects stale sends before their side effects.
- Resume keeps the existing dialog and optional agent wake behavior.
Agent reports from interrupted runs remain allowed.
## Model Used
OpenAI Codex, based on GPT-6, assisted with design, implementation, code
execution, and browser verification. The exact runtime model ID and
context window are not exposed in this session. The agent used reasoning
and tool calls.

## Linked Issues or Issue Description
**What happened?**
Stop could leave an embedded ACP provider running. A queued follow-up
followed by “go” could fail before it reached the provider. Task chat
could show a generic missing-response message. Even a restored session
could use the previous run's credential and fail its task update.
**Expected behavior**
Stop waits for confirmed provider termination. A later explicit wake
continues the same compatible session only when recorded actions have
known outcomes. It carries pending comments and the current run's
environment. Uncertain actions retain a visible reconciliation hold.
Composer Stop preserves the existing pause rule: conversation can
continue while paused, but task work requires Resume.
**Steps to reproduce**
1. Start an embedded ACP task.
2. Send a second request while the provider is running.
3. Interrupt the run, then send “go”. Also test composer Stop followed
by Resume work.
4. Check that the request is delivered once and that the provider can
complete the task through the current run's API credential.
5. Repeat with an unfinished write. Confirm that the write stops and
that further execution stays blocked with a visible reason.
**Paperclip version or commit**
Built from source on master at `3bc60dd8b` plus this branch.
**Deployment mode**
Local source build with an isolated embedded PostgreSQL instance.
Refs #11183. Refs #12552. Those changes address recovery after operator
cancellation. This change also covers embedded ACP termination, session
proof, pending-comment delivery, and task feedback.
## What Changed
- Propagate Stop into embedded ACP and wait for bounded adapter cleanup
and provider exit. Retain the actual ChildProcess object for forced
termination on all platforms; never signal a recycled numeric PID.
- Preserve interrupted checkpoints only for acknowledged, local,
persistent sessions with settled reads or no tools. Keep writes,
incomplete actions, and forced termination blocked.
- Restore the same compatible provider session with the current run's
environment. Reject fresh-session fallback for an interrupted
checkpoint.
- Adopt pending comments on the next explicit wake. Stop alone does not
dispatch them.
- Share the execution-blocker rule across dispatch, Resume, and task
detail. Show Stopped or Couldn't start with the recorded reason. Resolve
the stopped agent for the run link, including reviewer runs.
- Keep execution reconciliation holds intact when generic recovery sees
queued comments or healthy child tasks.
- Add process, service, component, and browser regression coverage. Fix
disposable database cleanup and React test settling exposed by the full
suite.
## Verification
- Passed `pnpm -r typecheck`, `pnpm build`, and `pnpm
check:token-gates`.
- Passed all three `acp-stop-continuation.spec.ts` browser journeys.
They use an actual ACP child process and require task completion through
the agent API.
- Passed 165 adapter execution, operator-stop, and child-process control
tests, 17 queued-comment route tests, and 65 tests in the two adjusted
UI suites. Earlier focused recovery, heartbeat, and task-control tests
also passed.
- Manually used the browser to queue a request, Stop, send “go” while
paused, and Resume. The same session answered once and moved the task to
Done with the current run's credential.
- Manually interrupted an unfinished write. Its file size stayed fixed
for five seconds. “Go” showed the reconciliation reason and did not
start another provider prompt.
- Separate live Claude ACP smoke checks confirmed that Stop ended a
disposable local write and that a no-tool interruption could resume the
exact provider session. The browser fixture does not call Drive or
another external app.
- Passed all 5,615 UI tests and 3,090 other workspace tests. The CLI and
general server groups pass with targeted retries: two transient server
failures passed together on retry, and two embedded-database startup
failures passed after removing abandoned shared-memory segments from
this task's completed browser fixtures. All 144 serialized server suites
completed, with 2,189 tests passing after two transient HTTP socket
failures passed on retry.
- Passed all 135 heartbeat process/recovery tests, including a
deterministic regression that failed before the recovery-sweep fix.
- Passed 18 dispatch integration tests, including stopped-reviewer
links, company boundaries, and malformed run IDs.
- Greptile is 5/5 on `7dd170d83`, with zero unresolved review threads.
The security scan and all required CI gates pass for the same commit.
## Risks
- Safe continuation depends on complete tool reporting and a restorable
local provider session. Unknown outcomes remain blocked and require
reconciliation.
- Provider cleanup can take time. A timeout does not grant replay
permission.
- The change adds optional adapter context fields and an optional issue
projection. It does not change the database schema or require a
migration.
- Test cleanup truncates company data only in a disposable test
database.
## Model Used
OpenAI GPT-6, running as Codex with repository tools, code execution,
and browser interaction. The runtime does not expose a more specific
model deployment ID or context-window size.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The task composer is where operators direct running agents.
> - Operators need to stop work without leaving the conversation.
> - Existing pause controls already hold task trees and interrupt both
runner types.
> - This pull request connects the composer to those controls and
removes repeated feedback.
> - Operators can pause work quickly and still queue messages while
agents run.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Task pause, resume, and cancellation in the task page and composer.
**Current behavior**
The empty composer cannot stop a running task. Task controls require
extra confirmation and reason text. Pause can show several notifications
for the task already on screen.
**Proposed behavior**
Show Stop while this task runs and the composer is empty. Text or
attachments switch it to Send. Stop and the menu use the same manual
pause hold. Parent pauses include descendants. Keep task cancellation in
the menu with a compact confirmation. Show one quiet pause row and gray
cancelled-run details.
**Reason and benefit**
Operators can interrupt execution with one click. Drafts and queued
messages keep their existing behavior. The UI waits for actual
termination, including native cancellation acknowledgment.
**Breaking changes**
No endpoint, schema, or task-status change. Pause no longer asks for
confirmation or a reason. Resume now honors the existing wake-agents
option. Task notifications are suppressed for the task and subtree
currently in view.
Related UI work: #8228 changes navigation and composer shortcuts. This
PR covers execution controls. No duplicate Stop-button PR was found. The
change improves existing controls and does not duplicate a roadmap
milestone.
## What Changed
- Add Stop, pending feedback, duplicate-click protection, and inline
errors to the composer.
- Share the pause mutation across the composer, active-run controls, and
menu.
- Poll affected runs after a pause request. Require native cancellation
acknowledgment.
- Remove pause confirmation and shared reason fields. Reduce cancel
confirmation to its task count and actions.
- Honor wake-agents for executable tasks only. Preserve the pause when
recovery review is needed; show partial wake failures inline.
- Preserve explicit legacy reconciliation decisions while their
continuation waits for dispatch.
- Suppress notifications for visible task trees. Use quiet pause and
cancellation feedback.
- Add interactive stories using production controls and native/legacy
end-to-end tests.
## Verification
- User reviewed the running feature and revised Storybooks in the
browser.
- Rebased focused checks passed: 295 original targeted tests, 161
updated route/page/notification/status tests, and 26 recovery
integration tests.
- Both isolated runner journeys pass on the final revision (1.7
minutes). Coverage includes queueing, parent and child interruption,
persisted holds, no automatic continuation, reconciled resume,
cancellation, terminal exclusions, and no Stop toast.
- Native coverage uses real runnerd with a deterministic provider
fixture. Legacy coverage checks actual process termination. Live
hosted-provider execution was not tested.
- Repository typecheck and build, Storybook build, and token gates
passed after rebase. The final server typecheck/build also passed.
- The broad local run completed its general-server stage with 7,219
passing tests, 48 skipped, and two failures from cached pre-fix source
and a stale native provider fixture. Both failed tests pass in fresh
final-head reruns after rebuilding the fixture; the script did not
continue to its later local stages. CI runs all test groups on the final
revision.
- Final revision: all 31 applicable CI checks passed; Storybook visual
regression was skipped by its workflow conditions. Greptile: 5/5, zero
unresolved comments.
- Review `Tasks / Execution Controls` in Storybook. Type and clear a
draft, stop a run, expand cancellation details, and test the menu on
desktop and mobile.
## Risks
- Stop pauses descendants for a parent task. This is the existing pause
contract.
- A held task can remain active if interruption fails. The UI shows an
error instead of claiming termination.
- Resume can start multiple assignees when wake-agents is selected.
Backlog, blocked, and terminal tasks stay excluded. Existing execution
reconciliation remains mandatory where required; Resume never invents
action-outcome evidence.
- Notification suppression uses the visible task and cached subtree.
Notifications for unrelated work remain enabled.
## Model Used
OpenAI GPT-6 through Codex. The exact runtime snapshot and
context-window limit are not exposed in this session. Used reasoning,
tool calls, code execution, and browser inspection.
