A long-running Ask keeps observing authorized queued/running work, retires browser I/O on credential or screen changes, and restores question controls when no answer or observable submission receipt exists. Missing/null/nonstring/blank receipts now stop before any invented job poll; an opaque receipt is encoded as one path segment. No accepted request is automatically resubmitted, and no durable job is cancelled.

ADR 0039 retains its Proposed client-observation amendment; the accepted source/cutoff policy is unchanged. Backend liveness and claim fencing remain separate #974 → #979 work. Preserve #1135's safe presentation and shared retry notice when those App/API deltas integrate. This PR allocates no ADR, migration, or release number and changes no estimator or provider ownership.

Validation on implementation e1ab443 (final evidence head ce6f91b):

  • Six new receipt regressions failed before repair. Focused API/panel: 36 passed; full frontend: 58 files / 558 tests passed.
  • Lint, TypeScript/product build, and Storybook build passed. The existing chunk warning remains visible.
  • Synthetic time-axis, Voice schema/ingestion, ontology-neighborhood, documentation and docstring checks: 45 passed; final documentation checks: 7 passed.
  • Chromium Storybook at 1440×1000 and 390×844: question retained, recovery action visible, Ask enabled, no diagnostic content or horizontal overflow. Visually inspected synthetic screenshots are in docs/evidence/ask-receipt-20260930.

The gap baseline separates current main, exact observed open-PR heads, local authority revisions, cited standards, non-identifying full-table aggregates, and unavailable acceptance. It records all 175 PR review-thread observations and 174 available base-delta comparisons. The previous integrated panel failure did not recur; this does not erase the historical failure or explain it.

Fresh hosted Checks and one independent approval on this exact head are required. Authenticated candidate PostgreSQL-to-API/UI acceptance, synthetic-only k6 saturation evidence, protected merge and deployed delivery remain unavailable. Parent-first protected stack integration, normal squash auto-merge, and all active rulesets remain required. No self-approval, force push, or bypass.

Walkthrough

Ask 요청에 인증 세대 검증과 AbortSignal 취소를 적용했습니다. 고정된 15분 폴링 제한을 제거하고, 유효하지 않은 영수증이나 답변이 없는 완료 응답의 관찰을 종료합니다. 전송 오류는 localized recovery guidance로 표시합니다. 관련 테스트와 수용 기준 문서를 갱신했습니다.

Merge Risk: ⚪ Minimal · up to ce6f9

Ask requests now stop observing and return the original cancellation reason, even when cancelled while a response body is being read. No unresolved merge-blocking issue was found. Hosted checks and independent approval on the exact head are still required by the project process.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ce6f9

The change strengthens credential-bound cancellation and prevents retired requests from updating the current screen. No expanded data access or privilege was identified. Remaining uncertainty concerns prolonged polling when server work cannot reach completion.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed exposure is longer-lived authenticated browser observation of an existing owner-scoped job. The inspected flow does not introduce cross-account receipt authority, new worker privileges or broader execution scopes.

Trust Boundaries and Controls

  • observed — Submission and polling carry the originating bearer token. Receipt encoding prevents a supplied identifier from becoming additional client URL path segments, while token-and-generation checks prevent retired responses from entering the current panel. The panel uses generic recovery text rather than displaying backend failure diagnostics.

Resilience and Maintainability Implications

  • observed — The existing worker bounds active computation and provides stale-queued and orphaned-running recovery. These mechanisms counter an inference of unbounded provider execution caused by this PR, but do not prove eventual settlement during worker unavailability. The ADR explicitly preserves the unresolved execution-deadline and recovery-policy conflict rather than presenting client observation as its repair.

Exact-head review: the lifecycle split is causal. The panel now clears credential-bound presentation state immediately, uses both the current token and an authorization generation to reject retired completions (including A→B→A), and aborts the native request transport on credential retirement/unmount. askAgent() propagates the signal through submission and status polling and makes the poll delay abortable without claiming server-job cancellation. The focused tests cover retired success/error admission, credential/unmount abort, and current-request continuity. I found no additional source defect in this six-file delta. Keep normal merge gates non-transferable: this COMMENT is not an approval, and current-head hosted/security/CodeQL plus real rendered acceptance still decide promotion.

Current-head review repair authority (2026-09-07): CodeRabbit's exact-head finding at 8e14f11295c0ffeb26a270ee9b7d7b21f5f2c895 was valid. backendFetch() preserved AbortSignal.reason only while fetch() itself rejected; cancellation during a successful response body's json() returned the native AbortError, and cancellation during a non-2xx error body was swallowed and converted into BackendError.

Run 34087066324 reproduced both realistic RED cases (HTTP 200 and 503) against the exact prior product head. The minimum repair calls signal.throwIfAborted() when response-body parsing fails, on both the success-body and error-body paths, otherwise preserving the original parse error. The repaired focused suite passed 21/21 (api.test.ts + AskAgentPanel.test.tsx), oxlint passed with zero warnings/errors, and the production build passed. The workflow-free staging commit is ca240a69e0b09aedd868e90dff68c3c39ff697bc, tree c9225f894be50985f70c5205a1afb2c46481d597; the temporary workflow is absent from that tree.

That verified clean tree has now been replayed as non-force product commit 40742bcf48858c22ee9726693669391836b9a5ad, directly on prior product head 8e14f11295c0ffeb26a270ee9b7d7b21f5f2c895. Isolated RED→GREEN is not substituted for fresh required checks or independent approval. Keep merge blocked until exact-product-head hosted gates and qualifying independent review are terminal.

Ready is review admission only. I moved this PR back to Draft because exact-head Security Scan run 36724379268 failed on 10 PyJWT CRITICAL/HIGH/MEDIUM findings in uv.lock; CodeQL was skipped and Tests are not terminal GREEN.

Exact head: ce6f91b96490ff6869b4f6fbe8a0181d87e7ee21. This is not a rerun request and does not synthesize status, approval, or mergeability. Return to Ready only after a new exact head has applicable terminal GREEN checks, zero substantive unresolved review threads, and qualifying independent review. No bypass, force push, destructive rebase, merge, or closure was used.
