Codex round 2 review on PR #12957 caught two race conditions and one recovery gap, all triggered by cross-turn filename reuse (`claimCodeFile` intentionally returns the same `file_id` for the same `(filename, conversationId)` across turns). Plus naming cleanup the user requested — internal "phase 1 / phase 2" vocabulary leaks across sprints, replace it everywhere with terms describing what's actually happening. P1 — stale render overwrites newer revision (process.js) Two turns reusing `output.csv` share a `file_id`. If turn-1's background render resolves AFTER turn-2's persist step, the unconditional `updateFile` writes turn-1's stale text/status over turn-2's pending placeholder. Fix: stamp a fresh `previewRevision` UUID on every emit, thread it through `finalizePreview`, and make the commit conditional via a new optional `extraFilter` argument on `updateFile` (`{ previewRevision: <expected> }`). The defensive `updateFile` in `runPreviewFinalize`'s catch uses the same guard so a programming error from an older render also can't override a newer turn. P1 — stale React Query cache on pending remount (queries.ts) Same root cause from the frontend side. Cache key `[QueryKeys.filePreview, file_id]` may hold a prior turn's `'ready'` payload; with `refetchOnMount: false` and the polling gate on `pending`, polling never starts for the new placeholder. Fix: `useAttachmentHandler` invalidates that query whenever an attachment with a `file_id` arrives. Both initial-emit and update events trigger invalidation — uniform gate. P2 — quick-restart orphans skipped by boot sweep (files.js) Boot `sweepOrphanedPreviews` uses a 5-min cutoff for multi-instance safety. A crash + restart inside the cutoff leaves `pending` records that never get touched again. Fix: lazy sweep inside the preview endpoint — if a polled record is `pending` and `updatedAt` is older than 5 min, mark it `failed:orphaned` on the spot before responding. Conditional on the same `updatedAt` we observed so a concurrent legitimate update wins. Cheap, bounded by user activity. Naming cleanup - `runPhase2Finalize` → `runPreviewFinalize` - `PHASE_TWO_TIMEOUT_MS` → `PREVIEW_FINALIZE_TIMEOUT_MS` - All `phase-1` / `phase-2` / `two-phase` prose replaced with "the immediate emit", "the deferred render", "the persist step", "the deferred preview", etc. Skill-feature `phase 1/2` references (different feature) left alone. Tests: 10 new (4 lazy-sweep × preview endpoint, 3 cache-invalidation × useAttachmentHandler, 3 extraFilter × updateFile data-schemas). Backend 332/332, frontend 531/531, data-schemas 37/37, lint clean. |
