## Thinking Path > - Paperclip manages AI agents and controls when their work can run. > - An agent pause waits until every earlier run has stopped. > - Recovery already treats verified workspace and AI-capacity waits as pre-dispatch outcomes. > - The stop proof did not accept those same receipts. Historical waits could keep an agent pausing forever. > - This pull request shares the resource-wait classification and the existing execution-event check. > - The benefit is consistent stop evidence without a new lifecycle command, database backfill, or host-boot assumption. ## Linked Issues or Issue Description Refs #18147 and #17718. This fixes the verified resource-wait case of #18147. It does not certify ambiguous historical runs that have no positive non-execution evidence. An agent can have an old cancelled legacy run with `errorCode: workspace_busy`, `executionStage: preparing`, and `executionRecovery: { kind: workspace_wait, providerWorkStarted: false }`. No process, native coordinator, or retained resource exists. Recovery recognizes this as a resource wait, but pause previously required a stop acknowledgment from an executor that never started. ### Credit and related work Thanks to @br1an-c0des (#17692) and @crownlayerapp (#15383) for the focused preparation and shared-admission analysis, @lucasweismann-ai (#18072) for the durable dispatch-evidence and race analysis, and @Pdesengrini (#18905) for the cancellation-receipt and process-identity guard cases. We reviewed these alternatives before implementing this smaller change. No contributor commits were cherry-picked. The design uses receipts already written by core. It does not adopt a reboot-time bypass, a new adapter-entry journal, or a pause-abort route. #17236 and #20037 address the separate cost of history reads. ## What Changed - Add one shared classifier for matching workspace and AI-capacity wait receipts. Use it in legacy recovery and cancellation stop proof. - Reuse the existing dispatch-event predicate instead of maintaining another event list. - Retain checks for native execution references, unresolved workspace obligations, controller leases, and resource cleanup. A live controller or cleanup still in flight cannot pass the proof. - Add a focused PostgreSQL suite. It drives the real pause worker with historical wait records and checks Retry eligibility against the same evidence. - Document the contract. No schema, API, UI, dependency, or scheduling change is required. ## Verification Source checkout on macOS arm64, Node 26.12.0, isolated local PostgreSQL 18, synthetic data only. ```sh node node_modules/vitest/vitest.mjs run --root server \ src/modules/agent-lifecycle/__tests__/resource-wait-stop.test.ts \ src/services/legacy-execution-recovery.test.ts ``` - 61 tests passed across these two files. - All eight positive regressions failed on unchanged master. The fix restores them. - After rebasing onto current master, the 61 focused tests passed again. Another 53 selected tests passed in `explicit-native-continuation.test.ts` with `-t 'pre-dispatch review wait|unclaimed workspace retry|historical native preparation'`. The other 361 cases in that file were not run. - Guard cases cover wrong/missing receipts, dispatch events, process identity, native ownership, live controller leases, workspace recovery, cleanup in flight, unreceipted remote resources, and an unknown historical HTTP dispatch. - A remote lease passes only after its exact termination receipt is stored. - Secret/PII diff scan and `git diff --check` passed. - Standard Greptile reviewed commit `201a61d2bb63290ca9b9b9d524e6c6715a872310`: [5/5 with no actionable findings](https://github.com/paperclipai/paperclip/pull/20384#issuecomment-6753165178). No review threads are unresolved. - Local testing is limited to affected cases. GitHub CI owns broad typecheck, build, and test coverage. Verification setup failures remain accounted for: worktree preflight could not complete because Cargo is unavailable; the first bundled PostgreSQL run failed because its macOS binary lacks a shared library. The focused tests passed on a separate, temporary local PostgreSQL 18 cluster. An early local server typecheck could not resolve the unbuilt Runner package; it is not claimed as a pass. ## Risks - Stop proof now accepts existing positive resource-wait receipts. Missing PIDs, terminal status, elapsed time, and a different boot ID remain insufficient. - The receipt must match its error code. The runtime must remain unresolved, with a preparation or settled stage and no conflicting native or workspace references. - The shared cancellation proof is also used by explicit continuation and Retry. Those paths keep their existing user-intent, ownership, pause, budget, and authorization gates. A stop proof does not itself start another run. - Runs that lack usable evidence remain held. This PR does not claim to repair every run shape reported on #18147. - No migration or live data edit is needed. No hosted deployment is included. ## Model Used OpenAI GPT-6 through Codex, with repository inspection, code execution, PostgreSQL regression tests, and GitHub tools.
