Release v3.8.31 — see CHANGELOG.md [3.8.31] for full notes and contributors.
Merged over known non-blocking reds (all correctness gates green): Integration Tests (2/2) is env/flaky (polls a real upstream batch that did not complete in the poll window); SonarQube/SonarCloud is the advisory server-side new-code quality gate. Unit (8 shards), Coverage, Node 22/24/26, Lint, PR Test Policy, Quality Ratchet, Docs-Strict, Quality-Extended and all 4 CodeQL analyses are green.
Threshold now derives from the live V8 heap ceiling (85%, floor 400MB) instead of a fixed 200MB that sat below the ~260MB app baseline and 503'd every request. Tracks --max-old-space-size across 1GB/2GB/large VPS.
