## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - #20645 lets a local same-run scheduled resume send the one same-conversation continuation for a turn lost on restore. It applies only when durable records prove three facts: the previous runner stopped, the attempt was admitted within the budget, and it is the same checkpointed conversation. > - It read the third proof from the coordinator's saved `failure_detail` while the phase was `retryable_failure`. > - In production, the resume reconciler (`claimNativeSessionResumptions`) claims the run first. It moves the coordinator to `observed` and clears `failure_detail`. So the executor never saw that evidence, and #20645 refused every real scheduled resume. > - The restart-chaos L7 wave showed this live. Codex B5 TM2 hit the exact path (`runner.drain` timeout, scheduled resume, `provider_turn_lost_on_restore`), sent no continuation, and needed Retry. > - This pull request makes the reconciler record that evidence durably when it claims the run, and makes the executor read it from there. > - The benefit is that #20645 works on the real path. The proof rule is unchanged. ## Linked Issues or Issue Description Refs #20645 **What happened?** Wave `w-20261110T212307-s9107` (L7, seed 9107, local, master plus #20645), task codex B5 TM2: - `native_session_recovery_failed: runner_local_connect_failed: PRP command runner.drain timed out`; - `retryable_failure` with `recoveryMode: "exact_checkpoint_resume"`, `recoverable`, `providerSessionEstablished` and `checkpointExists` all set; - `native.local_process_stopped`; - attempt 2 started; - `turn.failed` with `provider_turn_lost_on_restore` for the same turn ID that the checkpoint was running. No continuation was sent. The run failed with `native_provider_terminal_failed` and was preserved with `uncertain_provider_action`. **Expected behavior** The proven scheduled resume sends the single continuation. **Steps to reproduce** The new integration test below. The live path is timing-dependent (the L7 command in #20645). ## What Changed - `native-finalization-reconciler.ts`: when it claims a same-run resume, the reconciler appends one `same_run_resume` entry to `recovery_history`. The append is bounded like other history writes, and it runs in the same update that clears the failure. The entry copies `recoveryMode`, `recoverable`, `providerSessionEstablished`, `checkpointExists`, `successorRunId` and `replacementDenied` from the saved failure, with the controller boot and provider attempt. - `scheduled-resume-continuation.ts`: the evidence for the third proof now comes from either of two durable records: - the saved failure, when the executor claims a `retryable_failure` coordinator directly (unchanged); or - a reconciler claim: an `observed` coordinator whose last history entry is a `same_run_resume` entry naming the executor's own controller boot. The two other proofs are unchanged: the stop receipt, and an admitted attempt from 1 to 3. - `native-session-executor.ts`: passes the coordinator's last history entry and the controller boot to the decision. - `doc/execution-semantics.md`: describes the recorded evidence. Readers of `recovery_history` that look at the last entry do so only for restart claims, Stop recovery and shutdown suspension. Restart recovery's previous-claim lookup skips non-claim dispositions, so a `same_run_resume` entry does not change those paths. **Still refused** (tested): - every #20645 case; - the last history entry is not the resume claim, or there is no history; - the resume claim was recorded by another boot; - the claimed evidence is a bootstrap retry, has no checkpoint, or records a replacement; - a reconciler-claimed resume without a stop receipt. ## Verification - `native-scheduled-resume-continuation.integration.test.ts` now also runs through the real reconciler claim (`claimNativeSessionResumptions`) before `executePaperclipNativeSession`. On master the reconciler-claimed allowed case fails (`resumeInterruptedTurn` is false). With this change it is true, and the claim admits attempt 2. A reconciler-claimed resume without a stop receipt still passes false. - `scheduled-resume-continuation.test.ts`: decision cases for the reconciler-claim entry. - `native-session-resumption.test.ts` passes. 54 tests pass across the three files. - `cd server && npx tsc --noEmit` passes. - Live: not yet. The failing wave above is the reproduction. A rerun is timing-dependent. ## Risks - One more `recovery_history` entry per scheduled resume, inside the existing 20-entry bound. - The proof rule itself is unchanged. This only reads the same evidence from the record where it now survives. - No schema change. A run claimed by an earlier build has no `same_run_resume` entry, so it keeps the existing failure: refused, with Retry offered as today. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with tool use (shell, file edits, test runs).
