Type Alias: TrafficLight

TrafficLight = "green" | "amber" | "red" | "unknown"

Defined in: src/lib/performance/index.ts:9

Pure contractor-performance scoring (no I/O).

Consistency is the average fraction of contracted hours met across the weeks a contractor was active in the lookback window — each week capped at 100% so overtime in one week can't paper over a short week (mirrors the pay engine's ratio cap). A traffic light is derived from consistency.
