> [!NOTE] > Opened by Prospector's automated issue-fix pipeline. A maintainer reviews and decides; nothing here merges on its own. ## Thinking Path - Issue #15346 reports a defect in paperclipai/paperclip. - Root cause, as the fixing agent read it: ACPX saves one session record from several writers (live checkpoint timer, turn end, finalize, close) with no coordination; each save renames a temp file onto the same record file, and on Windows overlapping renames onto one file fail with EPERM. All of these saves go through Paperclip's session-store wrapper, which forwarded them concurrently. - This pull request: Serialize ACPX session record saves per record to stop overlapping renames (EPERM on Windows) ## What Changed - `packages/adapter-utils/src/acpx-engine/ephemeral-session-environment.ts`: Every ACPX save in Paperclip passes through this wrapper, so it now puts all saves of one record id in a single queue (a promise chain shared by all wrappers in the process). Saves of one record never overlap and keep their order; a failed save still returns its own error and does not block the next one; saves of different records still run in parallel. ## Verification - Reproducing test(s), added in this PR: `packages/adapter-utils/src/acpx-engine/ephemeral-session-environment.test.ts` - They fail on the base commit and pass with the fix, each twice in a fresh sandbox. - 3 independent attempts wrote 3 reproductions; this fix passes every one of them. - The repository's compile command passes with the fix applied. - 3 existing test file(s) near the change pass. - The full test suite passes except for the 246 file(s) that already fail on the base commit. ## Risks - Written by an automated pipeline, not a person: review it as you would an outside contribution. - Risk tier of the touched paths: 2. - The scope reviewer found it also changes, beyond the report: save() called when no earlier save of that record is pending - The scope reviewer found it also changes, beyond the report: persistedStore.save throwing synchronously - The scope reviewer found it also changes, beyond the report: Records with missing/undefined acpxRecordId - The scope reviewer found it also changes, beyond the report: save() for different record ids ## Model Used - opus, sonnet (Anthropic Claude, via Claude Code), writing and checking the change in an isolated sandbox. ## Linked Issues Fixes #15346 Other pull requests that name #15346: - #15370 (closed): fix(acpx): serialize session file saves and clean failed temporary writes ## 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) - [ ] 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) - [ ] 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 - [ ] 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 - [ ] I will address all Greptile and reviewer comments before requesting merge <!-- prospector:issue-fix v1 issue=15346 base=1c07b5903b1b report=4fe3fefc8864e00f --> Co-authored-by: commitperclip[bot] <284812584+commitperclip[bot]@users.noreply.github.com>
