Primary finding

State file backup (.bak) is never created before write, making corruption recovery impossible

The persist-state procedure restores `memory/topics/fork-release-state.json.bak` if `jq empty` fails after the write, and the prose claims to 'keep one .bak rolling.' However, no step in the recipe ever creates or rotates that `.bak` file (no `cp memory/topics/fork-release-state.json memory/topics/fork-release-state.json.bak` before the `mv`). On the first corrupt write the `cp` from `.bak` will fail (file doesn't exist), leaving the state file corrupt and unrecoverable — exactly the failure mode this guard claims to handle. The Step 0 bootstrap also never seeds a `.bak`.

Recommendation

Before writing `$TMP`, copy the existing state file to `memory/topics/fork-release-state.json.bak` (e.g., `cp memory/topics/fork-release-state.json memory/topics/fork-release-state.json.bak` immediately before the `jq | mv` sequence). Also seed the `.bak` in Step 0 alongside the initial state file so the first failed write is recoverable.

Inconsistent fork-processing cap: state seed says 50 but docs/process say 80

The seed state records truncated_to:50, but the process description and output template reference a cap of 80. This inconsistency is confusing and can lead to mismatched reporting or future code accidentally reading the stale 50-limit from state.

Recommendation

Choose a single cap and make it consistent everywhere: (a) if 80 is the intended limit, update the seed JSON to {"truncated_to":80} and refer to that value programmatically when trimming and when rendering; or (b) revert the docs to 50 and trim to 50. Consider deriving the cap from the state file to avoid drift.

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.
