Owner

Problem

fast-gate NewOffenseCheck compares [path, cop, message]. Metrics messages hold the count, so an existing offense whose count changes shows as a new offense and the gate goes red. Example: os-backlog smoke AbcSize 16.52 to 17.49 reported as new.

Reproduce

n/a: see rulings.tsv row R8 and finding-e memo.

Origin

Trigger: fast-batch-15 (#1329-#1336), ruling R8
Improvised this session: the batch suite and rubocop decided the merge
Chain: false red gate ← offense identity includes the Metrics count ← DESIGN (fast_gate NewOffenseCheck)
Root candidate: none found; searched NewOffense, offense, fast-gate, fast_gate, Metrics, AbcSize, false red
Where: plugins/os-sdlc/lib/os_sdlc/fast_gate
