Change

Fix a reproducible Ovis-side cause of Sent to Pi · transcript confirmation unavailable.

Pi's JSONL writer can pause after creating an empty file or writing only part of the final record. If that pause began before Ovis's pre-Enter capture, the before/after file stats are identical. Previously, lastEntry() rejected the incomplete record, but the capture helper classified the failure as permanent because it saw no stat change. Ovis then sent the message successfully while retaining an unconfirmable receipt, even if Pi completed the record immediately afterward.

• Distinguish incomplete records from malformed or unreadable transcripts.
• Retry incomplete captures through the existing three-attempt, 20 ms backoff; do not anchor to a partial record.
• Preserve complete-record parsing, expected-session, inode/path and append-boundary checks. No resending, new input authority, contract changes or FIFO relaxation.
• Add deterministic tests for an empty file, partial header and partial final entry that predate capture; bounded exhaustion; malformed complete records; and session mismatch.

This is a narrow fix for the reproduced race, not a claim that every existing unavailable receipt has this cause. Changed terminal input, session replacement and writes that exceed the bounded retry window can still leave a receipt unconfirmed.

Validation

• bun run check fast — passed (exit 0): workflow syntax, generated types/themes, TypeScript checks, production build and unit suite.
• Unit suite: 8,107 passed, 0 failed, 33 skipped, across 527 files.
• Included focused suites: server/pi-delivery.test.ts (31 passed), server/core/pending.test.ts (24 passed), and server/pi.test.ts (40 passed).
• Verification report recorded verified and source.unchanged: true.
• Independent read-only review found no correctness or identity-safety defects in the capture change.
• git diff --check passed.

Local Node is 24; CI uses Node 22. Integration/browser and native Windows checks are left to CI; no browser or Windows pass is claimed. Tests use temporary synthetic transcripts, not live user sessions.

Summary by CodeRabbit

  • Pi now retries transcript confirmation when a conversation record is briefly incomplete, including while a file is being written. Retries stop after a limited number of attempts if the record remains incomplete. Malformed complete records and session mismatches do not trigger retries.

Pi delivery capture now retries when a transcript is empty or ends with an incomplete record. Tests cover retry success, retry limits, and cases that do not retry.

Pi transcript confirmation now retries when a record is briefly incomplete. Those retries add a short wait before Enter is sent, and a prompt that opens in that window would not be re-checked. The window is small, so this can be handled with the suggested re-check or accepted as a follow-up.

Merging 75f49aa, an external fix from @philipprass-prog. Thank you! The merge pass's strict external review confirmed the bug on main. When Pi's JSONL writer had paused on an empty file or a partial final record before Ovis's pre-Enter capture, the unchanged file stats made the capture treat the incomplete record as permanent, so the receipt stayed 'transcript confirmation unavailable'. 992a1f3 retries only incomplete records, through the existing three-attempt backoff, and never anchors to a partial record. Complete-record parsing, the session, inode/path and append-boundary checks, and FIFO matching are unchanged. Four of its tests fail on main. CodeRabbit found that a prompt opening during that retry wait could still receive the pending message's Enter; the same window existed on main for the older retry triggers. The merge pass confirmed it with a deterministic test and fixed it on the branch in 853cbb1, which reruns the pending check after the receipt is prepared and reapplies the automatic-send guard. Its blocked, working and queue-held cases sent Enter on 992a1f3 and are refused now. The merge pass's re-review then caught that this recheck had dropped the check against the foreground PID captured before the wait, so a foreground process vanishing during the retry still got Enter. 75f49aa restores that check, with a disappeared-foreground test that fails on 853cbb1. Manual and steering sends, the lease and authorization are unchanged. bun run check fast and the contract harness pass, and the thread is resolved. The supply chain is clear: no dependency, script, workflow, network or credential change. Codex was at capacity, so an omo reviewer on gpt-6.1-sol and an independent second reviewer reviewed it. The required checks are green. A pre-existing, reproduced MEDIUM, a same-text external append that can confirm a receipt (on main as well), goes to a follow-up issue. LOW notes, not filed: a known foreign-session file with an incomplete last record is now retried rather than rejected at once (only the expected session is ever accepted; server/pi-delivery.ts ~168-175); pi-delivery.test.ts ~199 uses a non-null assertion.
