+## 데이터

+Raw append-only → Canonical PIT → DQ/Quarantine/Lineage → Feature/Forecast/Risk/Evidence → Ledger/Decision/Review/Publish/Outcome → Rebuildable Read Model 순서다. Read Model 외 역정규화를 금지한다.

+JobRunId, scope, watermark, idempotency key, source/dataset/version set, attempt, heartbeat, dependency result, artifact hash를 기록한다. Transient/Rate-limit/Schema/Data-quality/Business-hold/Poison을 구분하고 blind retry를 금지한다. 재처리는 새 revision이며 과거 Evidence를 덮어쓰지 않는다.
