Problem

A Claude file-change approval remained pending after its provider stream failed. Allow and Decline could no longer complete it, and switching the thread to Codex left the old approval card visible on mobile.

Failed-run finalization bypasses the request cleanup used during adapter event ingestion. Its synthetic terminal can also carry a fallback turn ID when the attempt started without one, which misses requests belonging to the actual streamed turn.

Change

Withdraw pending native requests for the root and its owned child turns in the failed-run finalization transaction, including their nodes and timeline items. Track pending request turn ownership while ingesting events, and exclude child work transferred to another run. Reuse the existing event normalizer and preserve the provider turn ID observed during streaming. Extend the transactional cancellation guard to approvals so cleanup preserves a response committed in the meantime.

Normal completion and failures explicitly marked as continuing child turns preserve their approvals. All clients consume the resulting persisted events through the existing shared state path.

Scope and approval

This is a focused fix for an observed lifecycle bug under the small-bug exception in CONTRIBUTING.md. It changes failed-turn cleanup and adds no product controls or defaults.

Related reports: #11799 (closed, approvals surviving provider death), #21935 (cancellation), and #24690 (Claude withdrawing a permission request). Existing PR #22023 handles stopped turns; #24767 handles CLI withdrawal. This PR covers failed-run finalization and leaves those other paths to their existing fixes. It does not repair historical stale rows.

Verification

• The observed-turn regression failed with the approval cancellation missing before the identity fix, then passed. It starts with a null attempt turn ID, receives a real provider-turn event, and ends with a stream error.
• Extended existing tests cover direct failed terminals, completed-turn and continuing-child controls, persisted request/node/item cancellation, other-turn isolation, child approvals, transferred-child preservation, and a response committed while cancellation is being prepared.
• vp run check:changed passed formatting, lint, both knip checks, GraphQL generation checks, affected-package typechecks, and 149 tests across five files.
• Server harness result: stream failure and direct failure include request withdrawal in finalization; normal completion and continuing-child failure preserve approvals.

Verification uses server harnesses and SQL projection tests. A fresh live Claude/mobile reproduction was not run. This is a server lifecycle change with no client layout changes.

Model and harness: GPT-6.1-Sol through Codex in T3 Code.

Approvability

Verdict: Approved at 7e71853

Macroscope's review found this PR approvable — Failed provider turns now withdraw stranded approval requests and their timeline entries. Cleanup is scoped to the affected turn and preserves concurrent responses and approvals for continuing child turns.

Explanation

The title "fix(server): withdraw approvals when provider turns fail" matches the main change: failed-run finalization now withdraws pending native approval requests, along with their nodes and timeline items, when a provider turn fails. It uses the conventional commit format and is specific enough for a teammate scanning history to understand the primary change.

Full details: Description check

Explanation

The description follows the repository template. It has Problem, Change, Scope, and Verification sections, and each contains specific content. The Problem section explains the stale Claude file-change approval after a stream failure. The Change section describes the fix and its boundaries. The Scope section cites the small-bug exception and related issues. The Verification section lists the tests run, the observed results, and what was not checked.

Major · Functional Correctness · Quick win

Withdraw approvals observed before a failed startTurn.

If startTurn emits turn T and an approval before it rejects, the forked consumer can persist both events. The failure handler then interrupts the consumer and writes the failed run without the observed turn ID or the pending-request snapshot. The terminal uses the derived failed:<attempt id> turn. Finalization normalizes withdrawal only for that derived turn and the run's root thread. The approval for T is therefore not withdrawn and can remain pending.

Stream-error recovery already passes routing.rootProviderTurnId and ownedPendingRequestTurns(routing). routing is not bound in this handler. After the interrupt, read eventRouting and pass the same two values:

Exclude withdrawn request records from the failed-child cascade.

When an owned child thread has an open approval node and its approval item, finalization adds cancelled snapshots for both. It then adds failed snapshots for the same node and item from cascadedSubagentEvents. The projection applies the later failed snapshots last, so they replace the cancellations. If an answer commits during this write, the guard removes the stale cancellations, but the failed cascade snapshots remain. Those snapshots can overwrite the answered node and item.

Filter the cascade output by the record IDs already withdrawn in this batch. Keep the cancelled snapshots and drop the duplicate failed snapshots.

The head clears the sidebar Approval status, but a separate Running · Ran command row with Stop remains visible.

Not shown:

• The Running · Ran command row with Stop remains visible on head; this proof establishes approval withdrawal, not tool-call row finalization.
• Concurrent answers, independently continuing child work, and synthetic failure turn-ID selection were not exercised by this single-provider SIGKILL scenario.
• Mobile, desktop shell, switching providers, and a real Claude file-edit approval were not exercised; the proof uses the web client and replay ACP approval.
• The follow-up click on the stale base Approve button was not performed; the scenario stops at the assertion proving that the unanswerable approval remains visible.
