## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The runner sends authorized tool calls to the server and saves their results. > - A provider turn can stop while a server write is still running. > - The old shutdown path invented a failed result that could conflict with the real result. > - Truncated execution input and incomplete recovery records made the failure harder to diagnose. > - This pull request preserves exact inputs and actual outcomes through shutdown and restart. > - Tests force the race and crash boundaries so safe retries do not repeat writes. ## Linked Issues or Issue Description **What happened?** Stopping a turn during a server tool call could record a false failure, then reject the actual result as a conflict. The diagnostic input formatter could truncate instruction content before execution. A crash during saved-result delivery could leave that delivery permanently indeterminate. Cleanup could hide the first failure, and a retry could overwrite earlier run logs. **Expected behavior** Keep dispatched tools pending until their actual result is known. Preserve accepted input bytes. Accept identical result delivery without failing the task. Reject conflicting results with enough evidence to diagnose them. Recover saved-result delivery without repeating the business operation. **Steps to reproduce** 1. Hold an instruction update at the filesystem commit barrier. 2. Stop its provider turn before the server returns the result. 3. Release the write, deliver its result, and replay the same result. 4. Repeat with a restart before and after the delivery receipt is saved. 5. Check that there is one write and one audit row, and that the exact result survives. **Paperclip version or commit** The change was developed from `44736c9c7` and rebased onto `0e5830887`. **Deployment mode** Self-hosted server with the native runner. Tests use local runner processes, scripted providers, and PostgreSQL. Related work: #12353 added durable semantic tool receipts; #12384 added durable Codex tool recovery; #12404 bound semantic tools to ACPX sessions. #14633 covers separate native-provider cancellation and qualification work. This PR addresses server semantic-tool outcomes and their durable delivery. No duplicate fix was found. AgentMail discovery is outside this PR. ## What Changed - Close turn admission without inventing results for dispatched tools. Keep pending calls and accept late actual results. - Accept identical result replay with a diagnostic warning. Include call identity and both result hashes in real conflict errors. - Preserve exact execution arguments. Reject prohibited or oversized input before dispatch. Keep diagnostic previews redacted and bounded. - Commit instruction-attempt evidence before the filesystem write. Save completed mutation receipts so concurrent and restarted duplicates return the first result. Recheck authorization before replay. An attempt without a completed result stays unknown and cannot execute again. Definite pre-write failures save and replay their original error without another write. - Recover an interrupted saved-result delivery only for backends with durable result receipts. Never replay an ordinary business operation with an unknown outcome. - Preserve the initiating error when cleanup also fails. Record incomplete settlement evidence. Propagate typed unknown-outcome errors through the native tool wrapper without creating a false completed tool result. - Append run-log attempts and restore the durable log before appending after local file loss. Reject incomplete restores. Publish a restored prefix only if the destination is absent so concurrent attempts cannot overwrite new lines. - Add deterministic race, crash, replay, authorization, exact-content, and log-restoration tests. Document their assertions in `packages/paperclip-runner/docs/durable-recovery.md`. ## Verification - Current head: `7e088f4c7fba8ebabf98ae95485a5753b013d489`. All 55 applicable checks pass; four conditional/manual checks are skipped. This includes build, typecheck, Rust, both runner TypeScript shards, server and workspace tests, all eight browser shards, isolated runner compilation, and the clean-install release dry run. [CI run](https://github.com/paperclipai/paperclip/actions/runs/36746101110). - Greptile reviewed this exact head at 5/5 with zero new findings. All three earlier review threads are resolved. - Focused local verification includes 11 instruction integration tests, 23 surrounding authority/tool tests, 26 run-log tests, and 169 controller/driver tests. The post-rebase controller/transport/runtime selection passed 415 tests. The full Rust release suite passed 617 tests with two ignored. The real-process SIGKILL recovery test passed three consecutive runs. - The fault matrix in `packages/paperclip-runner/docs/durable-recovery.md` uses explicit barriers, real PostgreSQL rollback, durable journal reloads, and killed runner processes. It covers late results, identical and conflicting replay, exact long content, concurrent log restoration, lost commit acknowledgements, and definite failure replay after the original CAS base becomes valid again. No paid model calls are needed. - Full local recursive typecheck and build passed during implementation. Server typecheck and the runner TypeScript build passed after the review fixes. The broad local repository test run was stopped after repeated database startup timeouts. Four timing/launch failures in an earlier broad runner run passed focused reruns without changed assertions or timeouts. These are local verification limitations; the complete current-head CI suite is green. An earlier CI workspace job received an infrastructure shutdown signal; its current-head replacement passed. ## Risks - A stopped turn can remain blocked when a dispatched operation has no proven result. The system does not guess its outcome or rerun its effect. - Conflicting results still fail settlement. Existing failed or conflicting journals are not repaired automatically. - Accepted semantic input is limited to 480 KiB of encoded JSON to fit the encrypted transport. Larger input fails before execution. - Instruction filesystem writes and database receipts are not one atomic storage operation. A separately committed attempt and audit record survive rollback. An attempt without a completed success or definite pre-write failure receipt remains blocked as an unknown outcome. It is not replayed or reported as success. - Run-log restoration now reads the durable object before appending when the local log is missing. Failed or incomplete reads reject the append. - No schema migration, dependency change, workflow change, or AgentMail change is included. ## Model Used OpenAI Codex, GPT-6, with reasoning, tool use, code execution, and test analysis. The exact served model ID and context-window size are not exposed in this session. ## 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 (focused suites; the broad local run limitation is recorded above) - [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: Paperclip <noreply@paperclip.ing>
