one alarm per capture job — coverage-record attribution (M-4/C-15)
Worklists
compile staleness + lane-ceiling approach
Memory headroom
90% of each function's memory — the F-15 growth-exhaustion class
Canaries, pipeline & cost
everything else carrying the rbxdata- prefix
Ops surface — reads CloudWatch on every visit; noindexed. Rows open each alarm's history; the capture-side twin is /coverage.
