  "_comment": "Fix-marker regression guard for RuView. Each marker asserts that a previously-shipped fix is still present. CI (.github/workflows/fix-regression-guard.yml) fails if a `require` pattern is missing from all of a marker's `files` (the fix was likely reverted) or if a `forbid` pattern reappears (the bug was re-introduced). Run locally: `python scripts/check_fix_markers.py` (or `--list`, `--json`, `--only ID`). Patterns are literal substrings unless wrapped in /.../ (regex). Add a marker whenever you ship a fix that would be expensive to silently lose.",
