## 요약

retry-backfill 계산/출력 증거 구현을 review loop 0에서 PASS로 종료했다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_local_G04_0.log` | `code_review_local_G04_0.log` | PASS | `retry-backfill` calculator, stable text/JSONL evidence, tests 통과. 리뷰 중 `gofmt`/EOF newline만 정리했다. |

## 구현/정리 내용

- `FreshnessObservation`, `GapBucket`, `BackfillDecision`, `DecideBackfill`로 missing/gap/provider delay/error 상태를 fresh success로 숨기지 않는 worker-local 계산 표면을 추가했다.
- `WriteBackfillText`, `WriteBackfillJSONL`로 stale/error 상태와 backfill window를 stable text/JSONL 증거로 출력하게 했다.
- missing, gap, provider delay, duplicate-only, error, nil observation, stable output fixture-style unit tests를 추가했다.
- 리뷰 중 `services/worker/internal/scheduler/backfill.go`와 `services/worker/internal/scheduler/backfill_test.go`에 `gofmt`/EOF newline 정리만 적용했다.

## 최종 검증

- `gofmt -l services/worker/internal/scheduler/backfill.go services/worker/internal/scheduler/backfill_test.go` - PASS; 포맷 정리 후 출력 없음.
- `go test -count=1 ./services/worker/internal/scheduler` - PASS; `ok git.toki-labs.com/toki/alt/services/worker/internal/scheduler 0.025s`.
- `go test ./services/worker/...` - PASS; worker 전체 package가 `ok` 또는 `[no test files]`로 종료했다.
