Pull request overview
This PR hardens render_diagnostics_report against JSON-based denial-of-service by switching to the repoβs bounded JSON loader, preventing untrusted diagnostics files from causing excessive memory use or pathological nesting depth issues.
Changes:
- Replace unbounded
json.loads(Path.read_text(...))with_load_json_bounded(...)when reading diagnostics JSON. - Remove the now-unused
jsonimport frompython/fast_mlsirm/report.py. - Document the JSON parsing DoS lesson/prevention pattern in
.jules/sentinel.md.
