## Thinking Path > - Paperclip manages agent work and the decisions that authorize it. > - A committed decision can leave effects unfinished after an interrupted execution. > - Recovery must preserve that debt without scanning settled history forever. > - Claims already store the state and time needed to schedule recovery. > - A failed claim must get another attempt even while newer claims arrive. > - Malformed claims need a durable failure outcome instead of an endless retry. > - This PR uses committed signals, saved deadlines, and bounded recovery rotations. ## Linked Issues or Issue Description **What happened?** Periodic decision maintenance queries for unfinished effects even when none remain. A cursor that only wraps after a short page can postpone an old failure indefinitely under continuous new work. Missing saved deciders or chosen options can also leave non-executable claims scanning forever. **Expected behavior** Open decisions and completed history produce no recurring effect-recovery SQL. Committed claims wake recovery, and restart reconstructs their deadlines. Genuine failures retain retries. Known malformed outcomes settle with an audit and preserve completed effects. Recovery must not invent authority, repeat committed effects, or lose continuation delivery. **Steps to reproduce** Create an old failing claim with a one-row recovery page, then keep adding newer due claims. Before the rotation fix, the old failure is never revisited. Separately, recover a claim with a missing decider or chosen option: the old implementation skips or throws on every attempt without settling it. Creating an ordinary open decision also caused an unnecessary effect scan. Stacked on #17479. Other decision expiry, continuation, target and retention duties have separate PRs in the stack. ## What Changed - Coalesce sequential committed notifications for up to one second without delaying already saved deadlines. This bounds instance-wide recovery reads and adds no idle polling. - Register effect recovery with the shared scheduler and transaction-aware notifications. Derive deadlines from the existing claim timestamp and recovery grace. - Remove effect recovery from recurring aggregate maintenance when the worker owns it. Preserve the explicit combined recovery entry point. - Page within a frozen final timestamp/ID and retain PostgreSQL precision at both boundaries. Failed claims and healthy later claims both make progress. - Load the current claim and derive recovery authority inside the shared execution flight. Preserve foreground joining, current authorization and per-effect locks. - Recheck known malformed claims under a row lock. Save a failed outcome, or partial when an executed effect receipt exists, with `effectRecoveryError` and an atomic `decision.recovery_failed` audit. Publish activity after commit and use normal continuation delivery. - Avoid effect-recovery notifications for open-decision creation. Claim and settlement writes retain their existing notification boundary. - Add generated migration `0390_salty_killraven.sql`, the concurrent, idempotent partial index for running-claim lookup. No queue table is added. - Cover quietness, transaction and lifecycle boundaries, retry fairness, malformed outcomes, and concurrent repair. Document the contract in `doc/idle-decision-effect-recovery.md`. ## Verification Current candidate normally integrates landed expiry `3421366903`, including expiry-only creation signals and all 21 independent master changes. The test revision is `dba8a79d1e1a5b97b8b5f6dac0f7c7837536531a`; the publication adds only this evidence documentation. - **143 current cases pass** across all 26 recovery, 54 decision, 20 expiry, 42 startup and one scoped-deadline cases. Server types/build pass with the rebuilt Runner vendor (1,524 inputs and 1,563 outputs). These results follow the landed dependency reconciliation; prior 69- and 141-case results remain historical evidence for their stated revisions. - Generated migration `0390_salty_killraven.sql` adds the existing running-claim partial index through the concurrent executor. All 388 parent journal entries are unchanged; five generated snapshots remain. Schema drift, numbering/safety and actual migration apply/replay pass. - Existing regressions exercise failed-claim rotation under sustained arrivals, malformed decider/option outcomes, atomic audit failure, row-lock repair races, current authority, foreground effect joining, coalesced tenant notifications, transaction commit/rollback, drain/resume, paging with PostgreSQL timestamp precision, and shutdown/restart. Completed effects are not repeated. - The first integrated run passed 140 cases and failed an overlap test that assumed the effect deadline was the scheduler's earliest deadline. Continuation coalescing now creates an earlier registered wake. The test services that earlier wake before asserting the original effect grace deadline; it still requires one shared effect flight, two lock attempts including the test gate, one committed comment and one continuation. No production timing was relaxed. - Earlier red/green fairness, malformed-claim, notification amplification and fixture failures remain recorded in [the owning audit](doc/idle-decision-effect-recovery.md). Extra upstream embedded-only tests attempted during parent integration could not initialize locally; CI must exercise that environment. - Previous candidate `f54a707d74` received both 5/5 reviews but its CI server shard 6 was interrupted (run 40597921712). The step was cancelled, with no failing assertion or suite summary, and the verify gate also failed. No retry or passing claim was made for that run. The necessary parent repair is included here; fresh CI and both reviews are required. Commands: server typecheck/build and Vitest for `decision-effect-recovery-work`, `decisions-service`, `decision-expiry-work`, `server-startup-feedback-export`, and `scoped-deadline-work`; DB migration checks, schema snapshot drift and real migration apply/replay. No full local repository-suite or deployed sleep/cost claim is made. Fresh current-head CI and Greptile/Ponytail are required before merge. ## Risks Missing deciders and missing chosen options now produce durable failed or partial outcomes instead of remaining running forever. Their audit and receipts remain available; no effect executes under invented authority. Only these known malformed states are settled this way. Database, audit, and other execution failures retain retries. Continuations retain their existing at-least-once delivery contract. The supported writer model remains process-local notifications plus restart reconstruction. Independent SQL writers and multiple replicas gain no new wake protocol. Cloud admission and durable external alarms are unchanged. These tests establish worker behavior, not deployed host suspension or fleet savings. ## Model Used OpenAI Codex, GPT-6 family, with reasoning and code execution.
