From ceabc3bc880676c49eee907a8d736f961a1358eb Mon Sep 17 00:00:00 2001 From: Nicky Leach Date: Wed, 7 Oct 2026 08:57:56 -0700 Subject: [PATCH] fix(e2e): wait on the server's own deferral signal in the signoff wakeup helper (#15345) ## Thinking Path > - Paperclip coordinates work for AI agents through server-managed tasks and heartbeats > - Signoff policy tests exercise stage transitions that wake the next participant > - A stage transition can defer a wake while the previous run still holds the issue execution lock > - The test helper used a fixed wait and could fail before the server released that lock > - This pull request waits on the server deferral signal and verifies the returned run identity > - The benefit is a stable test with clear failure details and no repeated wake request ## Linked Issues or Issue Description **What happened?** The signoff policy end-to-end spec failed intermittently with `No issue-bound heartbeat run became available for agent `. The server had deferred the wake while another run held the issue execution lock. **Expected behavior** The test helper waits for the named blocking run to finish, then reads and verifies the new run for the requested agent and issue. **Steps to reproduce** 1. Run `npx playwright test --config tests/e2e/playwright.config.ts tests/e2e/signoff-policy.spec.ts`. 2. Exercise a signoff stage transition while the previous stage run still holds the issue execution lock. 3. Confirm that the helper waits on the server deferral signal and returns only a matching run. This change relates to [PR #11299](https://github.com/paperclipai/paperclip/pull/11299), which also touches the signoff policy end-to-end spec. ## What Changed - Call the wakeup endpoint that reports the server deferral reason. - Wait for the named blocking run instead of using a fixed delay. - Verify that each returned run belongs to the requested agent and issue. - Bound read and wait loops and report the last server signal and lock fields on failure. - Keep one wakeup request per helper call. ## Verification - `npx playwright test --config tests/e2e/playwright.config.ts tests/e2e/signoff-policy.spec.ts` passed locally. - All five signoff policy cases passed locally. - The spec keeps all 60 assertions. - The diff contains only `tests/e2e/signoff-policy.spec.ts`. - The full CI end-to-end shards must pass before merge. ## Risks - The helper now depends on the wakeup endpoint's deferral fields. - A server change to those fields can fail the test with a named diagnostic. - The change affects end-to-end test behavior only. ## Model Used OpenAI GPT-5 Codex, exact runtime model `gpt-5-codex`, with tool use and code review assistance. The runtime does not expose a separate context-window value. ## 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 - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: nickyleach <331803+nickyleach@users.noreply.github.com> Co-authored-by: Paperclip --- tests/e2e/signoff-policy.spec.ts | 204 ++++++++++++++++++++++++++----- 1 file changed, 172 insertions(+), 32 deletions(-) diff --git a/tests/e2e/signoff-policy.spec.ts b/tests/e2e/signoff-policy.spec.ts index 71868b9a6a5..471589cf3cc 100644 --- a/tests/e2e/signoff-policy.spec.ts +++ b/tests/e2e/signoff-policy.spec.ts @@ -57,14 +57,91 @@ async function createAgentRequest(token: string): Promise { }); } -/** Invoke a heartbeat run for an agent, returning the run ID. */ +// The wait below follows the server's own deferral signal.
