## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - A run has an execution recovery budget: three provider attempts for native runs, and two failure retries for legacy runs > - In the restart chaos campaign, control-plane restarts used up that budget for runs that were healthy (RC-22, 22b, 22c, 40 and 60) > - #19720 and #19747 fixed two variants with watermark heuristics, and legacy interrupted preparation still spent the failure budget > - The durable-ownership plan (section F, invariant 5) asks for one rule: charge an attempt only when a recorded outcome proves that provider work started and no progress followed > - This pull request adds that rule and moves the native restart charge and the legacy preparation retry onto it > - The benefit is that a restart never spends budget for work the provider never started, while real failure loops and crash loops stay bounded ## Linked Issues or Issue Description Refs #19720, #19747, #19856 **What happened?** A control-plane restart charges a provider attempt by heuristics. The first crash restart always charges. A later restart charges unless the previous resume had no start evidence (#19747) or completed work (#19720). A runner that spawned but whose provider never accepted a turn counted as started, so a K6 crash loop could still spend the budget. Legacy runs whose preparation a restart interrupted (`providerWorkStarted: false`) spent `failureRetries`, the same counter as real failures (`execution-recovery-attempt.ts`). **Expected behavior** An attempt is charged only when the provider accepted a turn (`turn.accepted` or `turn.started`) and no accepted turn then completed work. A startup before spawn, a runner that spawned but was never admitted, and a `turn.start` the provider did not accept are not charged. The generation-12 cap still bounds uncharged restarts. **Steps to reproduce** Start a native run at its last attempt. Kill the controller after the runner spawns but before the provider accepts a turn. Before this change, the next restart claim blocks the run with `execution_recovery_budget_exhausted`. ## What Changed - New `server/src/services/native-runtime/provider-attempt-outcome.ts`: the one rule. `readProviderAttemptOutcome()` returns `provider_not_started`, `provider_started_without_progress` or `provider_progressed` from run events. `providerAttemptChargesBudget()` charges only the second. `providerAttemptWindowStart()` starts the attempt window at the latest `native.process_start_requested`, so earlier work never counts for a later attempt. `PROVIDER_ATTEMPT_CREDIT_GENERATION_LIMIT` (12) is the shared cap. - `restartResumeKeepsAttempt()` (`native-restart-recovery.ts`) now applies that rule to the attempt the restart interrupted, including the first restart. It keeps the unstarted-resume carry from #19747, the reattachment rule (an adopted provider counts as started), the drain exemption from #19625, and the generation-12 cap. A history entry from an older release without a recorded position still charges. - Legacy runs: `interrupted_preparation` is now an uncharged retry lane (`execution-recovery-attempt.ts`). It keeps its own counter, bounded at the same cap (12), and never changes `failureRetries`. `retries.ts` uses the longest transient delay after the second lane attempt. - `doc/execution-semantics.md` states the rule. - Accounting has its own "provider work started" readers (inventory Summary finding 5). Phase 3 owns those; this PR exposes the rule for them to adopt and does not change them. ## Verification - `native-runner-restart-recovery.integration.test.ts` (embedded Postgres, real `claimNativeRestartRecoveries`): 129 passed. New cases, red on master: - not charged at the last attempt for a claimed remote bootstrap, a remote bootstrap retry, and a claimed unlaunched remote run; - not charged when the runner spawned but was never admitted, and when the provider did not accept `turn.start`; - not charged on the first restart when the original attempt already made progress; - a normal retry that spawned but was never admitted is not charged, and earlier work still does not count for it. - Counter-cases, green on master and with the change: an accepted `turn.accepted` or `turn.started` with no progress is charged; the generation cap blocks at the last attempt; crash loops with and without progress stay bounded; the #19720 and #19747 cases still pass. - `execution-recovery-attempt.test.ts`: new lane tests (red on master). - `workspace-recovery-preparation-dispatch.test.ts` (25 passed), `heartbeat-process-recovery.test.ts` (interrupted-run cases), `run-dispatch/adapters/postgres.test.ts` (interrupted cases). - `server` typecheck (`scripts/typecheck-layers.mjs`, low-memory mode): no errors. - Not run: chaos waves (the coordinator schedules them on this host), and the full server suite (CI covers it). ## Risks - Behavior change: the first crash restart no longer charges when no accepted turn is recorded. If a crash lands before the controller projects the provider's `turn.accepted`, that attempt is not charged. This fails toward more retries, and the generation-12 cap bounds it. - A legacy preparation crash loop now gets up to 12 retries instead of 2. Each retry still passes the normal issue gates and keeps the transient delay. - The new queries use the `(run_id, seq)` index, once per restart claim. Nothing new runs before `turn.start`. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
