## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Tool requests and invocations store the execution outcome. Review cards show that outcome. > - The maintenance tick repeatedly joins these tables even when every card matches. > - Committed changes can wake repair. Existing rows can restore work after restart. > - A large company backlog also needs a bounded pass so other companies and shutdown can proceed. > - This PR uses the shared coordinator for scoped repair, continuation and failure deadlines. Settled history becomes quiet. ## Linked Issues or Issue Description **What happened?** The aggregate maintenance tick scans tool-review projections on every tick. Matching terminal history still causes database work. A company with many stale cards can also hold one worker in an unlimited drain. **What did you expect?** Relevant writes and startup should wake repair. Failed or unresolved cards should retain recovery. Matching history should cause no recurring SQL. Each normal worker pass should honor drain and shutdown. **Steps to reproduce** Start an instance with completed tool requests and matching cards. Leave it idle. The old maintenance tick keeps querying for mismatches. A large mismatch backlog also drains without a row limit or cancellation check. This is slice 07 of the sleep migration. It now targets master after #17458 landed. Related owners are pending expiry #17453 and approved recovery #17454. Their execution duties remain separate from card repair. The prior open-PR search found no duplicate projection migration. ## What Changed - Register company-scoped projection repair with the existing delivery coordinator. Remove its recurring aggregate-tick scan. - Signal through the existing review-write transaction owner and linked interaction mutations. Ordinary unlinked confirmations do not wake repair. - Keep interpretation, locks, current-state checks, activity and continuation callbacks in the gateway. A repair never repeats a provider tool call. - Limit each normal worker pass to 500 rows. Check abort and admission between rows. Save company progress through truncated and failed passes so blocked early pages cannot hide later cards. - Schedule truncated work after one second. Back off unresolved cards from thirty seconds to five minutes; fresh committed hints reset the delay. Clear obsolete cursors after empty reconstruction. - Skip repeated company discovery for scoped hints and the extra candidate query on an empty sweep with no saved cursor. Attempted or resumed passes still verify remaining mismatches because reflection returns no settlement result. - Add generated migration `0386_steady_epoch.sql` for the existing `(company_id, interaction_id)` lookup. Use the existing concurrent-index executor. Add no table. ## Verification Current candidate: `d4706fbf2a04a00ade30181eb1bd9322e8455818`. All 222 cases in the full gateway/projection/interruption, startup and scoped-deadline suites pass without skips after the query/retry efficiency repair; server types and build pass. A single committed company hint with matching retained history and a separate empty direct sweep each perform one candidate query. The unresolved-card regression failed before repair and now verifies backoff through the five-minute cap, prompt producer activation and quiet after settlement. An initial assertion incorrectly assumed an entire approval emitted one wake; its separate real writes require isolating the single-hint measurement. The earlier master integration `fe6e10629b` additionally established the following evidence before this efficiency follow-up: - **320 cases pass** across full gateway/projection/interruption, startup, scoped-deadline, narrowed identity-read and authenticated gateway HTTP suites. The HTTP selection includes all 81 cases. - **Six real PostgreSQL regressions failed before their fixes:** pass bounds, abort, drain, progress past unprojectable pages, progress past failed pages, and first repair after empty reconstruction. The complete owning selection passes all 220 cases. - Server production typechecking and build pass. Generated index migration, snapshot drift and numbering/safety checks pass. The five newest snapshots remain; master journal entries are unchanged. - A real missing-link query on 30,000 history rows changed from a sequential scan that filtered all 30,000 rows and touched 429 buffers to the new index with two buffers. Both treatments returned no rows. - Normal master integration preserves 35 independent performance files exactly. The gateway also retains master's narrowed identity read. Commands include `pnpm --filter @paperclipai/server typecheck`, `pnpm --filter @paperclipai/server build`, and server Vitest selections for `tool-gateway-service`, `server-startup-feedback-export`, `scoped-deadline-work`, `run-identity-projections`, and `connection-management.integration`, with separate PostgreSQL test fixtures. [The behavior and failure audit](doc/idle-tool-review-projection.md) records the producer contract, earlier fixture failures, index measurement, red/green regressions and integration evidence. Fresh current-head CI and Greptile/Ponytail remain required before merge. ## Risks - Signals use the existing single-active-writer database owner. Another replica or independent SQL writer needs a wake contract. - An already issued database query or reflection finishes before cancellation takes effect. Checks between rows bound further dispatch. - Legacy manual/global and disabled-scheduler one-shot repairs keep their complete-sweep behavior. The normal coordinator worker always supplies its row budget and admission controls. - Unprojectable cards and thrown failures retain recovery with a five-minute backoff cap. The company mismatch query still grows with terminal history. Empty history does not retain a recurring scan. - The index migration uses concurrent creation and the existing invalid-index recovery path. Prior SQL and journal entries remain unchanged. - Cloud sleep eligibility and external-wake coverage do not change. Local worker quiet is not proof of host or database suspension. ## Model Used OpenAI Codex, GPT-6 family, with reasoning and code execution.
