## 14:55 KST · M20 전후 Benchmark 기존 계측 owner 감사와 구현 전 checkpoint

Receipt: `20260807-work-session-m20-benchmark-inventory-r01`

### 결과
- M3, M14, M15, M18, LiveStageMetrics, runtime health와 Base Studio observability 경계를 실제 call-site에서 감사했다.
- 계측을 재사용, 최소 보완, 신규 필요, 제외로 분류하고 legacy YOLO11 M20 전후 및 향후 DeepStream RF-DETR 비교 방향을 기존 M20 owner에 기록했다.
- M20 구현과 Profile wiring은 미승인으로 유지하고 Base Studio 계측 owner와 bounded 수치를 다음 final measurement lock으로 남겼다.

### 검증
- 변경 문서의 상태, 상대 Markdown link와 git diff check를 검증했다.
- runtime, channel, container, Redis, config와 pointer mutation은 수행하지 않았다.

### 남은 작업
- Base Studio Event Persistence Observability의 exact owner와 Detailed cap, duration, TTL 및 Lightweight default-on gate를 잠근다.
- 별도 승인 전 M20 계측과 persistence worker 구현을 시작하지 않는다.

## 16:53 KST · M20 Event Persistence Observability 계측 Vertical slice 구현

Receipt: `20260807-work-session-m20-event-observability-r01`

### 결과
- 기존 M3, M14, M15, M18, runtime snapshot과 health owner를 재사용해 architecture-neutral event persistence 계측을 구현했다.
- Base Studio에 독립 Off, Monitoring, Debug 제어와 bounded Benchmark manifest 및 trace projection을 추가했다.
- M20 persistence worker와 event 동작, DeepStream 및 RF-DETR Profile은 미구현 상태로 유지했다.

### 검증
- 직접 계측, cap, manifest, 회귀 test와 strict overhead gate를 통과했다.
- Base Studio Playwright를 desktop, portrait와 mobile viewport에서 통과했다.
- 실제 channel, runtime, Redis, config와 pointer mutation은 수행하지 않았다.

### 남은 작업
- Base Studio 사용자 smoke와 legacy GStreamer YOLO11 Baseline A 측정이 남았다.
- M20 persistence worker와 reliability 구현은 별도 승인 전까지 시작하지 않는다.
