## Thinking Path > - Paperclip manages AI agents and their work. > - Queue admission must stop work while a previous execution needs recovery. > - The final dispatch gate can cancel a queued run before it starts. > - Legacy recovery treats this known wait as an unknown provider outcome and creates another hold. > - The extra hold can survive repair of the original execution and leave saved messages stuck. > - This pull request uses one database proof to prevent the extra incident and recognize old false holds. > - Saved input can then pass through normal admission with the original work and safety gates intact. ## Linked Issues or Issue Description Refs #15483. **What happened?** The dispatcher writes an `execution_reconciliation_required` cancellation when an existing recovery hold denies a queued run. No runtime is selected and no provider starts. Legacy recovery later creates a `legacy_execution_requires_reconciliation` action for that cancelled admission. Its settled `replay: blocked` record remains an effective hold after the real source recovery finishes. The task has saved messages but no eligible Retry or Continue action. **Expected behavior** A verified admission denial stays a wait. It must not create another provider-outcome incident. Existing false incidents must stop blocking after the server verifies their recorded source. Real execution, uncertain outcomes and file recovery stay held. The harness determines these infrastructure facts; the user does not certify them in a form. **Steps to reproduce** 1. Persist a queued-run gate cancellation with its task-bound `executionWait` receipt and no execution authority or resource evidence. 2. Run legacy reconciliation. On the old code, it creates a second incident. 3. Persist the old incident as resolved with replay blocked, then clear the original source hold. 4. Restart queue recovery with saved user messages. On the old code, no successor is admitted. Related work: #15965 covers other pre-start dispatch cancellations but explicitly excludes this existing-hold code and leaves historical holds unchanged. #16634 covers stale-cancel classification and queue drain, without re-evaluating historical effective holds. #15383 covers an operator Stop during conversation startup. This change addresses the existing-hold receipt and its persisted false incident; it does not copy those broader changes. ## What Changed - Add one database proof for a legacy admission denied by an existing execution hold. Require the exact dispatcher receipt, matching task identity, no runtime or process claim, no lease or finalization coordinator, and no execution events. - Use the proof before legacy recovery creates an incident and when it computes effective historical holds. Keep the old audit rows. - Preserve source file obligations and the original recovery action. Keep the normal queue, pause, ownership, company and budget checks. - Add real PostgreSQL regressions for incident prevention, old state, concurrent queue recovery, message order, conflicting evidence and scope boundaries. - Update the execution contract and both recovery maps. ## Verification - Red: the regression on unfixed source fails on incident classification, historical hold projection and actual periodic saved-message admission. The other 24 safety cases pass. - Green: all 27 new database cases pass. Two safety assertions were aligned with the existing contract: daily limits stop dispatch after queue promotion; a human comment can intentionally reopen a terminal task. The final regression checks the real daily dispatch gate and agent pause. - Existing `explicit-native-continuation.test.ts`: 255 tests pass. Existing legacy recovery and PostgreSQL dispatcher suites: 61 tests pass. - `pnpm -r typecheck`, `pnpm build`, `node scripts/check-maps.mjs` and `git diff --check` pass. - GitHub PR CI run `39313204660` passed on `ef6009e656b7c9b4c788480dce322874565960ac`. All 54 successful check-runs and the Snyk status are green. Two optional Storybook checks were skipped. The independent Paperclip Review completed with a neutral check and a 5/5 assessment with no findings. Greptile also reports 5/5 on the same commit. There are no unresolved review threads. - `pnpm test:run` is still running locally. Its overall result is pending; no full local suite pass is claimed. The exact-head GitHub CI suite passed. - A read-only probe of an affected hosted task verifies the same database proof and projects no false blocker with the working source. No live rows were changed. Deployment and a real resumed provider run remain unverified. ## Risks - An incorrect exclusion could admit work with uncertain effects. The proof fails closed on missing receipts, source mismatches, runtime/process ownership, any retained lease, coordinator, execution event or file obligation. Real upstream file recovery remains blocking in the regression. - The effective-hold query adds indexed existence checks scoped to the recorded run and company. It makes no provider calls and performs no database repair writes. - Historical audit records keep their recorded outcome. Only their effective blocking status changes when the server can prove the admission never ran. - No schema, permission, credential or UI form changes are included. Live recovery still needs verification after rollout. ## Model Used OpenAI Codex, model ID `gpt-6.1-sol`, with reasoning, tool use and code execution. ## 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: Paperclip <noreply@paperclip.ing>
