Pull request overview
This PR hardens the HTML diagnostics report renderer against JSON-based Denial of Service (DoS) by replacing unbounded json.loads(source.read_text(...)) parsing with the projectβs bounded JSON loader utility.
Changes:
- Replace direct
json.loadsof a fully-read file withfast_mlsirm.io._load_json_boundedinrender_diagnostics_report. - Remove the now-unneeded
jsonimport. - Document the JSON DoS learning/prevention pattern in
.jules/sentinel.md.
