State file updates are not synchronized; concurrent runs can clobber each other

Two instances running in parallel (e.g., separate queues or retries) can both read the same STATE_FILE, each compute a new version, and the last mv wins, dropping the other's updates. While the pipeline likely runs one postprocess at a time, the code has no locking to prevent lost updates.

Recommendation

Use a file lock (flock) around state read-modify-write sections or perform updates via jq with in-place atomic append guarded by a lock file. Alternatively, serialize via CI or ensure the workflow prevents concurrent invocations.

Other reviewer

The other reviewer flagged nothing in this file/line range.

Why this didn't post

This finding didn't meet AntFleet's unanimous agreement threshold. Both frontier models review every PR independently; only findings they both flag with the same severity and category are posted to the PR. This one fell through.
