to git diff. Preserve the existing RC-to-HEAD comparison and package.json
exclusion.

리뷰 · 우선순위 76 / 80이 PR은 release-244 검증을 막고 있던 Windows Desktop lifecycle 25개 시나리오 실패와 macOS 쪽에서 보이던 Cursor blob 입학 비용/타임아웃을 같이 푸는 수정입니다. 세 덩어리입니다. (1) bare Bun 워커가 run id만 공개하고 lock path/token을 안 넘기던 불완전 capability를, 획득한 lock을 통째로 자식에 전달하도록 지금 증거 측면에서 이 PR은 “추측 수정”이 아닙니다. incomplete capability를 되돌리면 25개가 다시 깨지고, 전달하면 통과하는 호스티드 토글이 있고, blob 쪽은 같은 케이스가 수백 ms에서 수십 ms로 줄어든 타이밍 비교가 있으며, apply는 28s lookup이 30s 예산에서 죽고 45s에서 원본 단언을 통과한 뒤, 잘못된 모델 alias로는 예산이 아니라 모델 단언으로 실패하는 ablation까지 있습니다. release-244에서 Windows/macOS 게이트를 다시 초록으로 만들 실무 PR로 봐도 됩니다. 경로 메인테이너의 판단이 필요한 지점

- Line 758: Update the job timeout configuration near timeout-minutes to bound
the complete crash-retry path, including a possible second full shard attempt
after a late first-attempt failure. Base the timeout on measured worst-case
retry duration, or revise the retry behavior around the crash-retry flow at the
referenced retry logic so a late crash cannot exhaust the remaining job budget.

Summary
Fix the Windows release-validation failures in all 25 Desktop lifecycle scenarios. A bare Bun run published its run ID but omitted the acquired lock path/token; the nested test preload refused that incomplete capability before loading the scenario. Forward the complete acquired capability while retaining live-owner validation and the real-home guard.
Remove repeated full-store scans when admitting a new Cursor blob. Preserve the 4096-entry ceiling, typed rejection of entry 4097, TTL, request pins, and byte accounting. The original 30-second timeout and all existing boundary assertions remain unchanged.
Give the real Desktop apply subprocess the existing 45-second spawn budget. Hosted tracing found a Windows known-folder lookup taking 22.8 seconds; the product allows that lookup alone 30 seconds. The old whole-CLI deadline could therefore beat a valid operation. All model, profile, cold-restart and cleanup assertions remain intact.
Verification
Windows follow-up repair: the Desktop fixture dropped the prepared PowerShell module-analysis cache and repeatedly rebuilt it in fresh profiles. A fixture-owned copy reduces apply from 23–27 seconds to 4.6 seconds while keeping the real API/ACL checks and original assertions. The original cache is read only. Windows 1/6 also exhausted the whole-job bound after 2736 passing tests; its batch limit is now 30 minutes, with six shards and all individual test deadlines unchanged. Updated full validation is pending. No production Windows identity implementation was changed.
Baseline: full validation run 34031250361 failed with the 25 Windows lifecycle errors and the macOS control timeout.
Hosted Windows causal toggle: incomplete-capability refusal reproduced; forwarding the acquired capability made all 25 original scenarios pass; restoring the original preload restored the failure. Earlier absolute/relative fixture-path comparison ruled out file selection.
Hosted macOS unchanged-test timing: original 547.29 ms, optimized 21.53 ms, restored original 782.91 ms. The 31-second full-control timeout did not reproduce in isolation; the final full-control run is required for acceptance.
Controlled valid slow lookup: a 28.2-second native lookup succeeded inside the product timeout, while the old whole-CLI deadline failed at 30.0 seconds; the 45-second subprocess budget let the same scenario finish at 31.4 seconds with all 22 original assertions passing. A diagnostic Python encoding error prevented that run's final ablation step.
Separate UTF-8-correct ablation: a valid but wrong production model alias still fails the original model equality assertion with the 45-second budget; no apply deadline failure.
Added regressions for nested Windows lock ownership and missing-capability refusal, plus incremental blob accounting and expiry transitions.
Local test suites, typecheck, and builds were not run, per maintainer instruction. Initial validation head
69f9e07c4fa7b80bcda9e4ba28e3c64f42187828included current devbd1cda99c. Cross-platform CI lane=all (including all six Windows shards and macOS control) and Service lifecycle finished: service lifecycle passed all three platforms. Manual CI passed Windows 1/6 (all original 25 lifecycle scenarios), macOS control (20,404 pass / 0 fail; the original 4096-entry case 18.27 ms), the other Linux/macOS shards, and all supporting gates. Windows 3/6 found a separate cold-restart fixture failure:Remote Desktop apply deadlinein the stored-profile=true case. The separate budget mismatch is now corrected, with controlled red/green and model-identity ablation evidence below. Final uninstrumented CI on the updated head is pending.Diagnostic-only branches modify CI for controlled experiments; those workflow changes are not part of this PR. No release or promotion is included.
Updated final head
9d624987cac669fe75276e081a129067e75058c0: full cross-platform lane=all and Service lifecycle are running. The PR is ready for technical review; merge remains conditional on those results and resolved actionable findings.Owned-cache isolation proof: copied cache, apply 4.6 s, full stored-profile cold-restart case 12.9 s, all original assertions pass. Single-variable comparison rules out simply disabling the cache or choosing an empty cache.
