## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The pull request workflow protects changes with a Playwright e2e lane. > - That lane already uses a weighted file partition so slow specs do not cluster by test count. > - Recent green PR runs showed the two e2e shard jobs were slower than the next slow required lane. > - The largest spec is indivisible, so a third shard lets that spec run alone and lets the rest split by duration. > - This pull request changes only the PR e2e shard matrix and the guard test. > - The benefit is a shorter expected PR critical path while the required `e2e` aggregate check name stays stable. ## Linked Issues or Issue Description Refs #9923 **What existing behavior does this improve?** The `pull_request` workflow Playwright e2e lane. **Subsystem affected** Cross-cutting: GitHub Actions CI and test scripts. **Current behavior** The PR workflow runs the weighted Playwright e2e partition across two jobs. Recent green runs showed those jobs as the slowest required checks. **Proposed behavior** The PR workflow runs the same e2e spec set across three weighted jobs. The aggregate required check stays named `e2e`. **Reason and benefit** The third shard lets the slow smoke-lab spec run alone while the rest of the catalog stays balanced. This should shorten the PR critical path. The win is bounded by fixed per-job setup time. **Breaking changes** None. The required aggregate check contract is preserved. ## What Changed - Change the PR e2e shard matrix from two entries to three entries. - Update the shard guard test to expect three shards. - Floor the balance bound at the largest single spec weight. - Assert that the workflow does not define more shard indexes than `SHARD_COUNT`. ## Verification - `node --test ./scripts/__tests__/e2e-shard.test.mjs` passes with 6 tests. - The recorded-weight partition is complete and non-overlapping: 168.0s, 116.5s, and 114.4s. - I checked `ROADMAP.md` and found no overlapping roadmap-level core feature. - I searched public GitHub PRs and issues for related e2e shard work. I found related PR #9923 and no open duplicate for this branch or change. ## Risks - This adds one extra GitHub Actions runner to the PR e2e lane. - The wall-clock win is bounded by fixed per-job setup. - Behavior risk is low because the aggregate required check remains named `e2e`. ## Model Used OpenAI Codex, GPT-5, tool-enabled coding agent in this repository. The runtime did not expose the context-window size. ## 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: Cody <noreply@paperclip.ing>
