## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The server Vitest shards gate every pull request > - Two more server tests failed on pull requests that do not touch them (#19309, #19265) > - #19314 fixed four other flakes. These two have different causes > - Random CI failures slow every contributor and hide real regressions > - This pull request removes both root causes without retries or skips > - The benefit is fewer false CI failures ## Linked Issues or Issue Description Refs #19309, #19265, #19314 **What happened?** - #19309, job 127459915333: `workspace-recovery.test.ts` > "keeps ancestor Retry held when current proof changes: sibling_hold" received `requestId: null` from a second Retry request. - #19265, job 127481105563: `paperclip-control-plane-port.test.ts` > "retains a durably recorded governed terminal while its postcommit observer is pending: checkpoint timeout" failed with "native session checkpoint timed out after 100ms" before the terminal was recorded. **Root causes** 1. Workspace recovery (test race). `POST /issues/:id/retry` returns 202 and then starts `heartbeat.resumeTaskRetry` without waiting. The proof-change tests change state after the receipt. When the background nudge runs first, it admits the Retry and queues a run before the change. The new queued run is then the latest run, so the second Retry in `sibling_hold` is stale. I proved this locally: a 1.5 s pause after the receipt made every gate in the family fail with a queued run in the issue history. 2. Control-plane checkpoint timeout (budget too tight). `checkpointTimeoutMs: 100` applies to every checkpoint in the session, including the normal checkpoints before the terminal. On a loaded runner, one of those took more than 100 ms. The test expects only the checkpoint that the pending observer blocks to time out. ## What Changed - `server/src/services/workspace-recovery.test.ts`: add `receiptOnlyRecoveryApp`. It builds the same route app, but the route nudge does nothing. The two proof-change families ("keeps ancestor Retry held…" and "holds a failed-preparation HTTP Retry…") use it and call `resumeTaskRetry` explicitly, as before. - `server/src/services/native-runtime/paperclip-control-plane-port.test.ts`: the checkpoint budget is 1 s. The timeout case now waits for the run to fail with the timeout while the observer is still blocked, instead of a fixed 700 ms sleep. This also proves that the timeout fires while the observer is pending. ## Verification - With the forced 1.5 s pause and the fix applied: both workspace-recovery families pass (80 passed). - `npx vitest run src/services/workspace-recovery.test.ts -t "keeps ancestor Retry held when current proof changes|holds a failed-preparation HTTP Retry when current proof changes"`: 80 passed. - `npx vitest run src/services/native-runtime/paperclip-control-plane-port.test.ts`: 94 passed, run 3 times. ## Risks - Low risk. The changes are only in tests. The route nudge is a latency hint ("Maintenance redelivers it"). Other tests still cover it. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, used through Claude Code with tool use (shell, file edit, and GitHub CLI). ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
