## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Governed tools can wait for a human review before execution. > - Pending reviews already save a deadline and must reject approval after expiry. > - The server currently scans for expired reviews on every maintenance tick. > - Empty scans keep the database active without advancing work. > - This pull request schedules pending review expiry from committed changes and saved deadlines. > - Configured idle state and resolved history no longer cause this expiry scan. ## Linked Issues or Issue Description **What happened?** The combined tool review sweep repeatedly queries pending expiry even when no pending request has a deadline. **What did you expect?** Signing or resolving a request should update the expiry schedule. A saved expiry should trigger settlement. Once no expiry remains, this duty should stop querying. **Steps to reproduce** Start a claimed instance with heartbeat scheduling enabled. Leave it idle with no pending tool reviews. Observe pending-review expiry discovery in the maintenance sweep. Stacked on #17450; earlier slices are #17446 and #17443. These all reuse the delivery and transaction foundations from #15625. This PR owns pending-review expiry only. Approved-action recovery, interrupted-execution quarantine, and terminal interaction projection repair remain separate migrations. No duplicate pending-review expiry migration was found in the open PR search; credential lifetime changes in #17221 and #17274 concern the parent credential slice. ## What Changed - Replace repeated company review-deadline aggregates with an indexed single-row lookup. Add and replay a concurrent covering-index migration and generate combined snapshots throughout the stack. - Extract pending-expiry selection and settlement into its owning service. Keep provider execution and interaction publication with the gateway. - Signal deadline assignment and pending resolution inside the owning SQL transaction. Preserve outer commit/rollback and central uncertainty handling. - Register company expiry deadlines with the shared scoped coordinator. Reconstruct on startup; normal producer hints reload only their company. Preserve writes during drain and concurrent reconciliation. - Settle request expiry and invocation failure atomically. Keep interaction projection recovery in the existing separate sweep. - Remove pending-expiry scanning from the main tick. Preserve the combined manual API and startup-only behavior when scheduling is disabled. - Add a partial pending-expiry index through an idempotent concurrent migration. No queue table is added. - Document supported producers, quiet states, remaining duties, and external wake limits. ## Verification - CI run `40574661575` at `f5c935d1b89877033eb82bf890f867baeb372ef3` lost the runners for general-server shard 9/12 and E2E shard 2/8 at 20:09:03 UTC. Both job logs explicitly show a runner shutdown signal followed by cancellation; no test assertion failure was reported by those jobs. A single infrastructure retry is justified once the run completes; it has not been issued yet. Both current-head reviews are 5/5, and CI must still be green before merge. - Current master landing at `f5c935d1b89877033eb82bf890f867baeb372ef3`: 128 complete gateway expiry, startup, scoped deadline and preparation-timing cases pass with no skips. Server types and the production server build pass. Landed tracing changes from #17918 are preserved. The master migration journal prefix remains semantically identical, with only this PR's two migrations added. Fresh remote CI/review is required before merge. - Parent reconciliation at `17539e2a6cf8ac4922b3cbe06af6df361bfe5665`: 116 tests pass across the full tool gateway service, startup and scoped deadline suites against a dedicated migrated PostgreSQL database. No cases were skipped. Server typecheck passes. Fresh remote CI and review are pending. Current head: `ec28076f825e76a267f05517ff0c44a3e2283ce7`. This remains a single-duty PR stacked on #17450. - Integrated pinned master `8548173fc9efdc0fa07644fb92dcc0b6851a95e5` with normal merges. Every branch passed generated-schema checks and its target-branch migration-order gate. Existing SQL is unchanged; the 25 stack migrations follow master’s new migration. - Duty-specific producer coverage, lifecycle tests, and earlier failure records: [2026-10-24-recurring-server-sleep-stack.md](https://github.com/paperclipai/paperclip/blob/ec28076f825e76a267f05517ff0c44a3e2283ce7/doc/plans/2026-10-24-recurring-server-sleep-stack.md). - Combined tip `51e6cbe67979b55b340ea9f0f434c5b5c682ccd6`: **355 startup/cancellation/recovery/dispatch/preservation tests**, **75 connection-management tests**, and production server typechecking pass. These combined checks do not mean every intermediate PR independently ran the full repository suite. - Real master-to-stack database upgrade passes: **379 unchanged prior migration receipts plus 25 new migrations**, with the gateway responsibility fixture preserved. - Owning-branch checks: 84 runner installation/settlement cases plus runner typechecking and generated TypeScript/Rust profile agreement; 253 GitHub review workflow cases. Stop-attribution and held-worker readiness regressions failed before their fixes. - Failure accounting: the initial combined run passed 349 cases and failed six idle assertions in a reused preservation database containing old cancelled runs. Repeating the combined command with a fresh preservation database passed. Earlier invalid project selection, merge import/type errors, and the interrupted full local suite are not counted as passing checks. - **Latest-head CI and review remain required.** Prior CI findings include GitHub idle observation, route teardown, attention cleanup, touch-picker E2E, workspace health, and voice-cleanup timing; local passes do not erase those failures. No full local repository-suite, deployed sleep, fleet cost, or live Copilot qualification claim is made. ## Risks - All supported producers must share the database signal owner. Independent SQL writers and other replicas need a live notification contract; startup alone does not cover them. - A crash after authoritative expiry and before interaction projection still relies on the existing projection-repair duty. That duty, approved-action recovery, and uncertain execution recovery remain periodic in this slice. - Unknown external outcomes remain quarantined. Provider calls stay outside SQL transactions. Expiry is still checked before approving a request even if physical cleanup waits during drain. - The new index uses the existing top-level migration executor because PostgreSQL concurrent index creation cannot run in a file-wide transaction. Snapshot pruning follows the repository rule. - This establishes worker quiet and reactivation, not deployed host suspension. Existing Cloud idle-safety and external alarm coverage remain unchanged. ## Model Used OpenAI Codex, GPT-6 family, with reasoning and code execution.
