## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The execution service owns each run and saves messages sent while it runs. > - Interrupt must stop the current executor before it delivers those messages. > - Remote Grok commands did not register the host cancellation control. > - A cancelled task run could still write Done and prevent queue recovery. > - This pull request connects remote cancellation and revokes cancelled run writes. > - Saved input can use the existing queue admission rules after verified cleanup. ## Linked Issues or Issue Description **What happened?** Interrupting a queued message marked a remote Grok run cancelled before its sandbox stopped. The old run could still post a reply and mark the task Done. Its saved follow-up remained deferred behind execution recovery. **Expected behavior** Stop revokes run write authority and waits for verified termination. Saved messages remain durable and enter one successor through normal admission after cleanup. **Steps to reproduce** 1. Run a task with `grok_local` in a remote sandbox. 2. Send a follow-up and use Interrupt while the command runs. 3. Let the old command attempt a task status update after cancellation. 4. Observe the task disposition and the saved message queue. **Paperclip version or commit** The gap is present in master at `d3e0f0a238`. **Deployment mode** Authenticated server with a Daytona sandbox. Related work: #14028 and #14046 handle bounded continuation. #13291 covers infrastructure interruption and verified remote cleanup. #13332 addresses atomic recovery holds. This change handles direct Grok operator cancellation and stale task writes. ## What Changed - Register remote Grok cancellation before preparation. Keep command ownership until the host confirms sandbox termination. - Reuse the sandbox cancellation boundary for the direct CLI invocation. Reject fresh attempts after cancellation and preserve workspace restore failure evidence. - Reject writes from cancelled task JWTs and runs with a pending stop. Preserve diagnostic reads and existing conversation error codes. - Recheck run authority under a database lock before task updates and interaction responses commit. - Preserve authorized handoffs that stop their own run. Only the server-issued stop receipt for that request permits the final task update. - Add tests for hung commands, unverified stops, early cancellation, copy-back failures, late Done, late interaction responses, authorized handoffs, exact lease receipts, and one queue successor across concurrent restart sweeps. - Document the cancellation and write-authority contract. ## Verification - Targeted adapter, cancellation-boundary, authentication, queued-message, interaction-service, and activity-route tests passed. The expanded run passed 214 tests; one new test had an incomplete fixture. After correcting the fixture, all 8 selected follow-up cases passed. - `pnpm -r typecheck`: passed on `179c86caf1bf0d89914a503d46e24af7e4b8c557`. - `pnpm build`: passed on the same commit. - `pnpm test:run`: the general-server group completed with 13,521 passed, 99 skipped, and 18 failed tests. It then stopped, so the remaining local groups did not run. Five Slack, email, and wake-batching failures passed on focused reruns after correcting the local environment. The remaining 13 failures reproduce as `EACCES` on rename in unchanged skill-cache code on macOS. Two custom-image suite setup hooks also failed to start embedded PostgreSQL after the machine exhausted shared-memory slots; all 31 tests in that file passed on rerun after the local resource issue was resolved. CI covers all test groups. - CI: 53 checks passed and 2 were skipped on the latest commit, including the aggregate verification gate. The last server shard passed on its single rerun after a preview-server startup timeout. The affected file also passed locally with 28 passed and 3 skipped. - Greptile: 5/5 on the latest commit. Both review threads are resolved. - No live deployment or staging task mutation has been performed. ## Risks - Stopping the sandbox can prevent file copy-back. The result preserves workspace restore failure evidence; termination does not imply restored files. - If provider termination fails, the adapter keeps ownership of its outstanding command and does not acknowledge Stop. - The write restriction now applies to ordinary cancelled tasks. Reads remain allowed. Task and interaction checks add a shared run-row lock to agent mutations. An exact server-issued receipt permits the task request that stopped its own run to complete its handoff. - Existing terminal tasks are not reopened automatically. An operator must correct a historical late Done before its saved queue can continue. - No schema migration or UI change. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository inspection, code execution, and test tools.
