Where the numbers come from
  • Editor releases ingested 2h ago · package versions ingested 2h ago.
  • Net-fix (the heat strip) = fixes − known_issues per release — a raw difference, no weighting. The 0–100 build score shown elsewhere is a separate, documented formula.
  • Issue lifespan = first Known Issues mention → first Fixes mention, joined on UUM-id.
  • Domain bucketing groups free-text area labels via fixed regex rules; unmatched falls into Other.
  • Every chart links into the underlying release-note rows — if a number looks wrong, click through to audit it.
