## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - A native run saves the agent's workspace files after the provider turn (copyback). One controller owns copyback at a time and records a durable owner receipt on the run (`nativeWorkspaceFinalizationOwner`) > - When copyback of an accepted result fails, retained saved-work recovery exports the files from the kept sandbox. A task Retry waits for that recovery before it continues > - A control-plane restart can kill the controller while it owns copyback. The dead controller can never confirm its own stop, and nothing in the retained recovery path could release its receipt > - The recovery worker then spent one attempt on each recheck of that receipt until it was exhausted, and the accepted Retry kept saying "Paperclip is finishing the saved result" with no run. The task waited forever > - This pull request stops spending attempts on that recheck, names the real wait, and lets the board release the exact receipt so the same recovery and the same Retry continue > - The benefit is that an accepted Retry never waits silently: it finishes, or it shows one honest action that makes it finish ## Linked Issues or Issue Description Refs #19717 (same-host automatic proof for a killed copyback owner; this PR covers the retained-recovery path and the case where no automatic proof is possible) Refs #19713, #19609, #19694 (related restart-recovery fixes; no overlap in files except this doc) **What happened?** Two Daytona restart-chaos waves. In each, a native run's copyback failed and the run failed with `native_workspace_sync_out_retry_exhausted`. The agent's result was accepted. Retained recovery started. A SIGKILL of the control plane landed while a recovery attempt owned copyback: - Wave s13, task t06 (Claude, crash loop): Retry was accepted at 02:30:35. A SIGKILL landed 2 s later. All later attempts failed with `copyback_stop_unconfirmed`. After 6 attempts the recovery was exhausted. The Retry showed `retryWait.reason = finalizing_saved_result` for more than 15 minutes. No run was created. - Wave s12, task t01 (Claude): attempt 1 failed with "Workspace checkpoint payload mismatch". The SIGKILL at 01:43:54 killed the owner of attempt 2. Attempts 3 to 5 failed with `copyback_stop_unconfirmed`. The Retry was accepted with HTTP 2xx and produced no run. In both kept databases the run carries an owner receipt for the killed process. **Steps to reproduce** 1. Accept a native result and make its workspace copyback fail, so that retained recovery owns the export. 2. Press Retry on the task. 3. Kill the control plane while a recovery attempt owns copyback, so that its owner receipt stays on the run. Use another host, or a receipt without automatic stop proof. 4. Let recovery run. **Expected behavior** Rechecking the receipt does not spend attempts. The task names the wait and does not offer a Retry that cannot help. A board member can confirm that the previous server stopped. The recovery then finishes, and the waiting Retry continues by itself. **Actual behavior** `withNativeWorkspaceFinalizationOwnership` returned `owner_unverified` for a retained repair without creating any board action (`native-workspace-finalization-ownership.ts`, `requireStopVerification`). `recoverRetainedWorkspace` reserved an attempt for each recheck and failed it as `copyback_stop_unconfirmed` (`workspace-recovery.ts`), until the budget was exhausted. The Retry gate in `explicit-native-continuation.ts` returned `finalizing_saved_result` for an accepted result with no verified repair, with no check for this hold. `resumeNativeWorkspaceAfterOwnerStop` accepted only an `owner_unverified` action on a `running` run, so no route could release the receipt of a finished run. The exhausted handoff told the board to press Retry again, which repeats the same failure. ## What Changed - `server/src/services/workspace-recovery.ts`: when retained recovery finds an unverifiable copyback owner, it records the recheck without reserving an attempt. The 30-minute recovery window still bounds it. The retained action records the exact receipt as `workspaceOwnerRecovery: { state: "operator_required", owner }`. A newer receipt replaces the record and clears an older confirmation. - `server/src/services/explicit-native-continuation.ts`: a Retry that waits for an accepted saved result reports `workspace_owner_stop_required` when the run's active retained action has that hold. It no longer reports `finalizing_saved_result` for this case. - `server/src/services/task-interruption-presentation.ts`: the new wait has a fixed message, and Retry is not offered for it, because another click cannot release the receipt. - `server/src/services/native-runtime/native-workspace-owner-recovery.ts`: the existing board route `POST /issues/:id/recovery-actions/resume-workspace-finalization` (permission `runtime:confirm_owner_stop`) also accepts a retained recovery action with that hold. The confirmation must name the receipt that is still on the run. A live owner on this host still rejects it. It clears only that receipt, records the stop proof and an activity entry, and returns the same recovery to the worker. A spent budget gets one new generation, as a deliberate recovery request does. It accepts no result and starts no agent turn. The owner check is shared with the existing path. - `server/src/services/system-recovery.ts`: an exhausted `copyback_stop_unconfirmed` handoff names the board confirmation instead of another Retry. - `ui/src/api/issues.ts`: the route receipt's `resultId` can be `null` (a retained recovery has no live result binding). - `doc/native-workspace-finalization-recovery.md`: an additive paragraph describes this path. ## Verification - Red then green on embedded Postgres: `server/src/services/workspace-recovery-preparation-gates.test.ts`, "lets an accepted Retry finish after a killed copyback owner instead of waiting forever" with one case per wave (s13, s12). Each case uses a real accepted remote export, a Retry through the HTTP route, a killed-owner receipt, and 8 recovery passes. - Before the fix (both cases): `attempts: 6, state: "exhausted"`. That is the wave state. - After the fix: no attempt is spent on the recheck. The hold is recorded. The Retry wait is `workspace_owner_stop_required` with `canRetry: false`. The board confirmation through the route returns 202 and clears the receipt. The same recovery completes. The same accepted Retry then finishes the saved result (s13: the task is `done`) or continues in exactly one new run (s12). - `npx vitest run src/services/workspace-recovery-preparation-gates.test.ts -t "killed copyback owner"`: 2 passed. - `pnpm verify` (affected selection): see the comment below. Server `tsc --noEmit` is clean. - No live Daytona replay. Both waves ran on old signed images. The local proof uses the same accepted-export fixture as the existing Retry tests, with the receipt state copied from the kept databases. ## Risks - A copyback owner on another host that is still alive is now rechecked within the recovery window without spending attempts. Before this change it spent them. The window still bounds the wait. - The board confirmation for a retained action is an operator statement, the same as the existing owner-stop path. It is limited to roles with `runtime:confirm_owner_stop`. It never clears a receipt other than the one it names, and a live same-host owner still rejects it. - #19717 changes the same ownership area and adds a UI action for the running-run case. That UI does not show a retained action yet. After both merge, a small follow-up can show its button for this hold. Until then the API route and the task's wait message cover it. - Not addressed here: the "Workspace checkpoint payload mismatch" that started wave s12. The checkpoint outbound transfer extracts without `-p` (`sandbox-managed-runtime.ts` checkpoint sync-out, `extractHostTarball` in the Daytona provider), so the host umask can change file modes that the remote manifest recorded. That is a separate signature. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, through Claude Code with tool use (shell, file edits, test runs, embedded Postgres). ## 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 - [ ] 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>
