Problem

When Claude Code withdraws a permission request it no longer needs (control_cancel_request), the thread keeps showing "Approval needed". This happens, for example, when a PermissionRequest hook already allowed the command. The card stays until someone clicks it, and the click does nothing because the tool already ran. The Claude adapter stopped waiting when the SDK's abort signal fired, but never reported the request as closed, so it stayed pending.

Fixes #27282

Change

When the wait in canUseTool ends because Claude aborted it rather than because the user answered, the adapter now emits the request, its node and its turn item as cancelled. That is the status the server already gives native questions left open when a turn ends. AskUserQuestion requests wait the same way and get the same handling.

The adapter checks whether the user's answer reached it, not only whether the signal aborted, so a request that got an answer stays resolved.

Scope and approval

Fixes the bug in #27282. The reporter reproduced the CLI side headlessly: can_use_tool, then control_cancel_request for the same request 70 ms later, then the tool result, while the T3 projection row stayed pending.

Verification

• New test in ClaudeAdapterV2.test.ts: opens an approval in an approval-required turn, aborts the SDK signal, ends the turn, then checks that the latest request, node and turn item updates are cancelled. Without the fix it fails with expected 'pending' to equal 'cancelled'.
• The existing approval tests in that file still pass (8 in the run).
• Server typecheck, lint and format pass.

Not checked: a live Claude Code session with a PermissionRequest hook.

Walkthrough

The Claude adapter now cancels runtime requests, execution nodes, and turn items when Claude withdraws an unanswered permission or user-input request. Regression tests cover Bash approval and AskUserQuestion cancellation.

Changes: Claude request cancellation

Layer / File(s)	Summary
Withdrawn request handling apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	When an answer or decision remains pending after waiting ends, the adapter marks the runtime request, execution node, and turn item as cancelled. Tests check that withdrawn Bash approval and AskUserQuestion callbacks deny and that their artifacts are cancelled.

Full details: Linked Issues check

Explanation

Issue #27282 is closed and supplies historical context only. No active directly linked coding requirements apply. The reviewed changes still implement the reported behavior: withdrawn Bash and AskUserQuestion requests mark the runtime request, node, and turn item as cancelled, while answered requests remain resolved. Focused regression coverage verifies both request types.

Full details: Out of Scope Changes check

Explanation

The whole-PR changes are limited to ClaudeAdapterV2.ts and ClaudeAdapterV2.test.ts. The adapter changes cancel withdrawn requests. The tests verify the cancellation behavior. These changes directly support the PR's stated bug fix. No unrelated product behavior or files are included.

- Line 9699: Update the withdrawn-request handling around Deferred.isDone and
cancelWithdrawnRequest so cancellation is emitted before terminal finalization
can stop event ingestion, even when a result arrives while the aborted approval
callback is still running. Add a regression case that queues the result
immediately after aborting the callback and before joining its fiber, and verify
the cancellation event is preserved.
- Line 7110: Update cancelWithdrawnRequest to apply the pending-cancellation
guard to approval artifacts as well, persisting cancellation only when the
request, its node, and its turn item are still pending; preserve any response
already committed by dispatchRuntimeRequestRespond.

Verified in a real dev environment

verified unchanged head 2f7a0a221c832148c136bd59b6cebb8ed20a1c8d on linux with the real dev web app, repository playwright, chrome 151, and claude code 2.1.316 using claude-haiku-5-5 through the local proxy. the project and threads were created through the app against a real git repository. no mocks or seeded conversations were used.

reproduced on github/main at 5732bbee39: a project-scoped PermissionRequest hook allowed the harmless zsh associative-array command from the issue. the command returned probe-a and probe-b, while the request stayed pending and the client still showed “waiting for approval”. main's server was stopped before starting the pr's server.

the exact same scenario on the pr completed without a stuck card. the request, node, and turn item all persisted as cancelled. the real provider result identifies the permission decision as hook-approved. normal approve still executed the command; normal decline prevented execution without retrying. a separate codex gpt-6.1-sol turn ran a terminal command and returned codex-neighbor-ok.

all 256 existing ClaudeAdapterV2.test.ts tests passed through blacksmith, including both withdrawal cases. ci has no failing or pending jobs; eight jobs were skipped. no source changes or pushes were needed.

sanitized runtime transcript. main's later shutdown cleanup is identified separately from the pending state observed before shutdown.

the recording was inspected and uploaded playback and seeking were checked. the withdrawn request is too brief to distinguish in the recording; the stored states and provider result establish that part.
