hyungi f325bd0509 feat(observability): digest/briefing 을 처리 보드에 맥미니 작업으로 노출 (background_jobs)
큐 밖 cron 생성 작업(global_digest/morning_briefing)이 processing_queue stage 가
아니라 보드에 안 잡혀, 맥미니가 11분짜리 digest 를 돌려도 idle 처럼 보였다.
ebbcaf8 의 background_jobs 메커니즘 재사용:
- digest_worker/briefing_worker = start_job→finish_job (best-effort, 본작업 무해)
- pipeline = cluster 완료마다 heartbeat(processed/total) → 진행바
- queue_overview = kind→machine 맵으로 payload 에 machine 필드 (맥미니 귀속)
- 보드 = 머신 레인에 dot 점등 + "생성 중: <label> N/T" 표시

"""처리 머신 보드 + ETA 집계 (plan ds-processing-ui-6an, 안2+안5/6).
GET /api/queue/overview 의 집계 로직. 모든 수치는 기존 processing_queue /
documents 컬럼에서 라이브 계산 — 신규 테이블/마이그레이션 0 (HARD 제약).
구조: SQL 수집부(build_overview 내부 5쿼리)와 판정부(순수 함수)를 분리.
판정부(rows_to_* / build_machines / build_summarize_eta / build_trend /
build_totals / compute_eta_minutes)는 DB 없이 단위테스트 가능.
귀속 규칙 (단일 진실):
- stage→machine 정적 맵: gpu = extract/embed/chunk/markdown/preview/thumbnail/
fulltext/stt · macmini = classify/summarize · macbook = deep_summary
(단, settings.ai.deep 부재 시 deep_summary 도 macmini 귀속).
- summarize 는 풀(pool): pending/processing/failed 는 macmini 귀속이되, 완료
실적(done_*)은 documents.ai_model_version 조인으로 분리 — 'qwen-macbook'
이면 macbook 실적, 아니면 macmini 실적.
- deferred_pending(payload.deferred_until 미래)은 macbook 카드 귀속
(보류 = 맥북 불가 신호).
