chore(quality): baseline-headroom skips generated and vendored files in the fileSize worst-file signal - #12291
Merged
Conversation
…in the fileSize worst-file signal The nightly headroom monitor flagged fileSize 🟡 permanently because the worst frozen file was src/app/docs/lib/openapi.generated.ts — frozen at its emitter's exact output size in #12212, i.e. ~0% headroom BY CONSTRUCTION (growth is policed by conscious re-freezes, never by editing the module). Same class: open-sse/vendor/** (upstream code nobody slims by hand). isMonitorExemptFile() excludes .generated. modules and vendor/ paths from the monitor's worst/near-cap accounting only — check:file-size itself still enforces both. The fileSize row now points at the worst HUMAN-EDITABLE frozen file (currently tests/integration/skills-pipeline.test.ts at 4.5%, a true early warning: its baseline note already requires a split rationale for any further growth).

Fixes the chronic 🟡 on the
fileSizerow of the nightly 📈 Baseline headroom report (#12149): the worst frozen file wassrc/app/docs/lib/openapi.generated.ts, which #12212 froze at its emitter's exact output size — ~0% headroom by construction (growth is policed by conscious re-freezes, never by hand-editing the module).
