- Around line 217-220: Update the repair flow around the final digest check and
renameAtomicFile to acquire writer coordination before re-reading the rollout
and hold it through replacement, using the same coordination mechanism as Codex
rollout writes so concurrent appends cannot be lost. Add a regression test that
appends between the digest read and replacement and verifies the append is
preserved, maintaining the lifecycle guarantee.

Serialize the rollout write before replacement.
The digest check at Line 217 is not a compare-and-swap. Codex can append after that read and before Line 220 replaces the file. The replacement then publishes rewritten.content from stale bytes and drops the append.
Acquire writer coordination before the final digest and hold it through replacement. The coordination must also exclude Codex rollout writes. Add a regression test that appends in this interval. This is required for the guarantee documented in docs-site/src/content/docs/reference/cli/lifecycle.md Lines 86-87.

Summary
ocx recover-history --ocx-compaction <thread-id> --yescommand for a thread that persisted OpenCodeX-ownedocx1:remote-compaction state and must later resume through native Codex.ocx1:compaction items in authoritativecompacted.payload.replacement_history, and leave native opaque ciphertext and historical response events unchanged.Closes #3916.
Why this scope
OpenCodeX can decode
ocx1:only while its Responses adapter remains in the request path. Native ChatGPT treats the persisted envelope as native encrypted content and rejects it withinvalid_encrypted_content. Automatic bulk migration during restore would make a reversible configuration operation rewrite unrelated task history. This PR instead makes history mutation deliberate, single-thread-scoped, backed up, and default-off.Verification
