Codex 0.144.2 reverted a broken auto-review policy that degraded Guardian behavior, then shipped a version bump with no additional changes.

The team caught a prompting regression in Guardian's auto-review policy and request format, rolling it back in 0.144.2 [1] to restore previous behavior and tool reliability. That fix shipped immediately, followed by a clean version-only release at 0.144.3 [2] with no code changes. In parallel, the connector runtime refactor landed [3], moving Codex Apps tool caching into a reusable `codex-connectors` manager with atomic snapshot publishing and hardened disk persistence to prevent older fetches from overwriting newer state. Composer completion target resolution also improved [4], resolving `@` and `$` completions on both sides of the cursor while preferring the nearest editable mention and avoiding false positives on uppercase environment variables. These changes strengthen the caching layer and completion accuracy without touching the core inference path.
