    "Notes": "Strongest: a toggle is trivially traceable (handle → action_of_path → post → perform → Store.toggle → View.fragment or 303), helped by App being server-independent and each module having one clear job. Comments are nearly all 'why' (Budget rationale, cookie age, migration rule, CSP hash, JS render invariants) with no noise. Weakest: handle's `filter p \u003c\u003e None ... Option.get (filter p)` double evaluation is clunky and hides intent; Store errors surface only as failwith exceptions caught by run_server's generic logger, and user_version's exec result is ignored; main.ml's Budget/connection plumbing and nested try blocks take effort to follow; a few terse names (change, shows, done_, go) need a moment."
  },
  "ReviewFindings": [
    "[correctness] `apps/ocaml/static/app.js:14` — Filter navigation can discard queued edits. With a toggle request pending, edit another item and click “Active”: blur queues the save, but the ordinary filter link immediately unloads the page before that save runs. The changed title is lost. Wait for pending mutations before navigating between filters."
