## 계획 대비 변경 사항

## 주요 설계 결정
- `services/worker/internal/marketdata/aggregation` 신규 패키지에 `AggregateDailyToMonthly` 순수 함수를 추가했다.
- daily bar의 원래 wall-clock 연월로 grouping하고, 결과 monthly bar timestamp는 UTC 월초로 고정했다.
- daily bar의 UTC 기준 연월로 grouping하고, 결과 monthly bar timestamp는 UTC 월초(1일 00:00:00)로 고정했다.
- decimal 비교/합산은 외부 의존성 없이 `math/big.Rat`로 처리해 문자열 decimal 정밀도를 보존했다.
- provenance에는 source/target timeframe, target timestamp, source range/count, rule version `daily_to_monthly_ohlcv_v1`을 남겼다.
- provenance에는 source/target timeframe, source range/count, rule version `monthly-deterministic-v1`을 남겼다.
- aggregation rule: open=첫 daily open, close=마지막 daily close, high=max high, low=min low, volume=sum, timestamp=해당 월 1일 UTC, output timeframe=`market.TimeframeMonthly`.

SDD S04의 "월봉이 어떤 일봉 입력 범위와 aggregation 규칙에서 생성되었는지" evidence와 코드 주석의 "Each monthly bar has its own provenance record"를 만족하지 못합니다. 월별 bucket에 `sourceStart`, `sourceEnd`, `sourceCount`를 유지하고, provenance를 result bar별 전체 입력 범위가 아니라 해당 bucket 범위로 생성하세요.
- Required `services/worker/internal/marketdata/aggregation/monthly_test.go:335`: fixture comparison이 expected fixture의 `instrument_id`, `timeframe`, `timestamp`만 확인하고 OHLCV/currency/provenance를 검증하지 않습니다. 그래서 `services/worker/internal/marketdata/aggregation/testdata/monthly_expected.json:1`이 provenance JSON fixture를 전혀 포함하지 않아도 SDD S04 evidence가 통과 처리됩니다. expected fixture를 `bars`와 `provenance`를 모두 담는 구조로 복원/갱신하고, test가 모든 OHLCV 값과 provenance의 source range/count/rule을 비교하게 하세요. 특히 `monthly_daily_input.json:35`의 `2024-02-01T00:00:00+09:00` 같은 KST timestamp가 UTC grouping(`monthly.go:120`)에서 어느 월로 들어가는지도 fixture 비교가 실제로 잡아야 합니다.

> Do not ask the user directly, present choices in chat, or call `request_user_input` during implementation; record only the linked SDD/Milestone lock decision in `사용자 리뷰 요청` and stop for code-review.

## 개요
date=2026-06-19
task=m-backtest-multi-timeframe-coverage/03_monthly_aggregation, plan=1, tag=REVIEW_REFACTOR
## Roadmap Targets
- Milestone: `agent-roadmap/phase/backtest-loop/milestones/backtest-multi-timeframe-coverage.md`
- Task ids:
- `monthly-bars`: 월봉을 일봉 aggregation으로 생성하고, 생성 기준과 provenance를 저장/출력한다.
- Completion mode: check-on-pass
## Spec Targets
- SDD: `agent-roadmap/sdd/backtest-loop/backtest-multi-timeframe-coverage/SDD.md`
- Acceptance scenarios:
- `S04`: task=`monthly-bars`; evidence=`deterministic monthly OHLCV fixture와 provenance evidence`
- Completion mode: spec-check-on-pass
## Archive Evidence Snapshot
- Archived plan: `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/plan_local_G05_0.log`
- Archived review: `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/code_review_local_G05_0.log`
- Verdict: FAIL
- Required summary:
- `services/worker/internal/marketdata/aggregation/monthly.go:185`: provenance가 각 monthly bar의 해당 월 source range/count가 아니라 전체 입력 source range/count를 반복한다.
- `services/worker/internal/marketdata/aggregation/monthly_test.go:335`: fixture comparison이 OHLCV/currency/provenance를 비교하지 않고, `monthly_expected.json`도 provenance fixture를 포함하지 않는다.
- Affected files:
- `services/worker/internal/marketdata/aggregation/monthly.go`
- `services/worker/internal/marketdata/aggregation/monthly_test.go`
- `services/worker/internal/marketdata/aggregation/testdata/monthly_daily_input.json`
- `services/worker/internal/marketdata/aggregation/testdata/monthly_expected.json`
- Verification evidence:
- Review rerun `go test ./services/worker/internal/marketdata/...`: exit code 0, but current tests do not prove SDD S04 fixture evidence.
- Review rerun `go test ./services/worker/...`: exit code 0.
- Review rerun `git diff --check`: exit code 0.
- Narrow archive reread allowed if exact prior context is needed:
- `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/plan_local_G05_0.log`
- `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/code_review_local_G05_0.log`
- Roadmap/spec carryover:
- Roadmap task `monthly-bars`.
- Spec scenario `S04`.

- [ ] USER_REVIEW가 연결된 SDD/Milestone 결정으로 완료/PASS 해소되면 `USER_REVIEW.md`를 해소 상태로 갱신하고 `complete.log`를 작성한 뒤 task directory를 archive로 이동한다.
## 계획 대비 변경 사항
- plan에는 `monthly_daily_input.json` timestamp convention을 UTC로 바꾸는 선택도 언급했으나, 기존 KST(+09:00) timestamp를 유지하고 UTC 기준 grouping 결과를 expected fixture에 일치시키는 선택을 했다. 이는 기존 fixture/input convention을 깨지 않으면서 provenance fix의 목적(각 월별 source range/count 검증)을 달성하기 위한 선택이다.
## 주요 설계 결정
- `monthBars` struct에 `srcStart`, `srcEnd`, `srcCount` 필드를 추가하여 월별 bucket 단위로 source range/count를 추적한다.
- provenance 생성 시 `ProvenanceForBar(bar, mb.srcStart, mb.srcEnd, mb.srcCount)`로 각 월의 고유한 source range/count를 전달한다.
- `monthly_expected.json`을 `bars` + `provenance`를 모두 포함하는 구조로 변경했다.
- `TestAggregateDailyToMonthlyFixtureComparison`을 typed struct로 fixture를 파싱하게 수정하고, OHLCV/currency/timestamp/provenance source range/count/rule id를 모두 검증하도록 변경했다.
## 사용자 리뷰 요청
_기본값은 `없음`이다. 구현 중 새 결정이 필요해 보여도 직접 질문하거나 선택지를 제시하거나 `request_user_input`을 호출하지 않는다. 이 섹션은 선택된 SDD 결정 또는 선택된 Milestone `구현 잠금 > 결정 필요` 항목이 실구현을 차단할 때만 채운다. 외부 환경/secret/서비스 준비, 검증 증거 공백, 반복 실패, 일반 범위 조정은 사용자 리뷰 요청이 아니며 `검증 결과`, `계획 대비 변경 사항`, 또는 code-review의 일반 follow-up plan으로 처리한다._

## 리뷰어를 위한 체크포인트
- 월별 provenance가 각 monthly bar의 실제 source daily range/count만 담는지 확인한다.
- fixture expected가 deterministic monthly OHLCV와 provenance evidence를 모두 포함하는지 확인한다.
- `TestAggregateDailyToMonthlyFixtureComparison`이 SDD S04 evidence를 실제로 검증하는지 확인한다.
- UTC grouping 또는 market wall-clock grouping 선택이 구현, fixture, `계획 대비 변경 사항`에서 서로 일치하는지 확인한다.

# Plan - Monthly Aggregation Review Follow-up
## 이 파일을 읽는 구현 에이전트에게
구현 마지막 단계는 반드시 `CODE_REVIEW-*-G??.md`의 구현 에이전트 소유 섹션을 실제 변경 내용과 검증 출력으로 채우는 것이다. 구현 후 active 파일을 그대로 두고 리뷰 준비를 보고한다. 종결, archive 이동, `complete.log` 작성은 code-review 전용이다.
선택된 SDD 결정 또는 Milestone `구현 잠금 > 결정 필요` 항목이 실구현을 막을 때만 review stub의 `사용자 리뷰 요청` 섹션을 채우고 멈춘다. 구현 중 사용자에게 직접 질문하거나 선택지를 제시하거나 `request_user_input`을 호출하지 않는다. 환경/secret/서비스 차단, 일반 범위 조정, 검증 공백은 사용자 리뷰 요청이 아니라 `검증 결과` 또는 `계획 대비 변경 사항`에 기록한다.
## Roadmap Targets
- Milestone: `agent-roadmap/phase/backtest-loop/milestones/backtest-multi-timeframe-coverage.md`
- Task ids:
- `monthly-bars`: 월봉을 일봉 aggregation으로 생성하고, 생성 기준과 provenance를 저장/출력한다.
- Completion mode: check-on-pass
## Spec Targets
- SDD: `agent-roadmap/sdd/backtest-loop/backtest-multi-timeframe-coverage/SDD.md`
- Acceptance scenarios:
- `S04`: task=`monthly-bars`; evidence=`deterministic monthly OHLCV fixture와 provenance evidence`
- Completion mode: spec-check-on-pass
## Archive Evidence Snapshot
- Archived plan: `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/plan_local_G05_0.log`
- Archived review: `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/code_review_local_G05_0.log`
- Verdict: FAIL
- Required summary:
- `services/worker/internal/marketdata/aggregation/monthly.go:185`: provenance가 각 monthly bar의 해당 월 source range/count가 아니라 전체 입력 source range/count를 반복한다.
- `services/worker/internal/marketdata/aggregation/monthly_test.go:335`: fixture comparison이 OHLCV/currency/provenance를 비교하지 않고, `monthly_expected.json`도 provenance fixture를 포함하지 않는다.
- Affected files:
- `services/worker/internal/marketdata/aggregation/monthly.go`
- `services/worker/internal/marketdata/aggregation/monthly_test.go`
- `services/worker/internal/marketdata/aggregation/testdata/monthly_daily_input.json`
- `services/worker/internal/marketdata/aggregation/testdata/monthly_expected.json`
- Verification evidence:
- Review rerun `go test ./services/worker/internal/marketdata/...`: exit code 0, but current tests do not prove SDD S04 fixture evidence.
- Review rerun `go test ./services/worker/...`: exit code 0.
- Review rerun `git diff --check`: exit code 0.
- Narrow archive reread allowed if exact prior context is needed:
- `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/plan_local_G05_0.log`
- `agent-task/m-backtest-multi-timeframe-coverage/03_monthly_aggregation/code_review_local_G05_0.log`
- Roadmap/spec carryover:
- Roadmap task `monthly-bars`.
- Spec scenario `S04`.
## 범위 결정 근거
- 같은 Milestone task와 SDD S04 evidence를 닫기 위한 follow-up이다. Roadmap Targets와 Spec Targets는 유지한다.
- DB migration, provider 월봉 import, backtest selector integration은 여전히 제외한다.
- 현재 review file의 구현 설명은 UTC 기준 grouping을 선택했다고 기록했다. 이 follow-up은 기본적으로 그 선택을 유지하고 fixture expected를 그 규칙과 일치시킨다. 만약 구현 중 market wall-clock grouping으로 바꾸는 것이 맞다고 판단하면 `계획 대비 변경 사항`에 plan deviation과 근거를 남기고, 모든 fixture/test 기대값을 그 결정과 일치시킨다.
## 구현 체크리스트
- [ ] `AggregateDailyToMonthly` provenance를 월별 bucket source range/count 기준으로 수정한다.
- [ ] `monthly_expected.json`을 deterministic monthly OHLCV와 provenance evidence를 모두 포함하는 stable fixture로 갱신한다.
- [ ] fixture comparison test가 OHLCV, currency, timestamp, provenance source range/count, rule id를 모두 검증하게 수정한다.
- [ ] `go test ./services/worker/internal/marketdata/aggregation -count=1`, `go test ./services/worker/internal/marketdata/...`, `go test ./services/worker/...`, `git diff --check`를 실행한다.
- [ ] CODE_REVIEW-*-G??.md의 구현 에이전트 소유 섹션을 실제 구현 내용과 검증 출력으로 채운다. 이 항목이 완료되기 전에는 구현이 완료된 것이 아니다.
### [REVIEW_REFACTOR-1] Per-Month Provenance Correction
#### 문제
현재 `AggregateDailyToMonthly`는 월별 result bar를 만든 뒤 전체 입력의 `sourceStart`, `sourceEnd`, `len(validatedBars)`를 모든 provenance에 넣는다. 이러면 January monthly bar도 February daily source를 provenance로 가리킬 수 있어 SDD S04의 source range evidence가 틀린다.
#### 해결 방법
월별 aggregation bucket에 `sourceStart`, `sourceEnd`, `sourceCount`를 함께 유지한다. 각 월에 bar를 추가할 때 해당 bucket의 source range/count만 갱신하고, result 생성 시 같은 월의 provenance를 만든다. `AggregationRuleID`는 기존 `monthly-deterministic-v1`을 유지하거나 상수로 승격한다.
#### 수정 파일 및 체크리스트
- [ ] `services/worker/internal/marketdata/aggregation/monthly.go`: 월별 source range/count를 bucket 단위로 기록한다.
- [ ] `services/worker/internal/marketdata/aggregation/monthly_test.go`: 각 monthly bar provenance가 해당 월 daily input만 가리키는지 검증한다.
#### 테스트 결정
기존 deterministic OHLCV test에 provenance range/count assertion을 구체화하거나 별도 test를 추가한다. 최소한 두 개 이상의 월이 있는 input에서 각 월의 provenance count와 start/end가 서로 다르다는 것을 검증한다.
#### 중간 검증
```bash
go test ./services/worker/internal/marketdata/aggregation -count=1
```
### [REVIEW_REFACTOR-2] Fixture Evidence Restoration
#### 문제
`monthly_expected.json`은 bare bar array만 포함하고 provenance fixture가 없다. `TestAggregateDailyToMonthlyFixtureComparison`도 expected fixture에서 instrument/timeframe/timestamp만 확인하므로, OHLCV와 provenance가 틀려도 SDD S04 evidence가 통과할 수 있다.
#### 해결 방법
expected fixture를 `bars`와 `provenance`를 모두 담는 stable 구조로 갱신한다. test는 fixture를 typed struct로 decode하고, actual result를 같은 fixture shape으로 변환해 deep comparison 또는 field-by-field comparison을 수행한다. 현재 input fixture의 `+09:00` timestamp를 유지한다면 UTC 기준 grouping 결과가 expected OHLCV/provenance에 반영되어야 한다. UTC boundary 혼선을 피하려고 fixture를 UTC timestamp로 바꾸는 경우에는 그 선택을 `계획 대비 변경 사항`에 명시한다.
#### 수정 파일 및 체크리스트
- [ ] `services/worker/internal/marketdata/aggregation/testdata/monthly_expected.json`: `bars`와 `provenance`를 모두 포함한다.
- [ ] `services/worker/internal/marketdata/aggregation/monthly_test.go`: fixture comparison이 OHLCV, currency, timestamp, provenance source range/count, rule id를 모두 비교한다.
- [ ] `services/worker/internal/marketdata/aggregation/testdata/monthly_daily_input.json`: timestamp convention이 expected fixture와 일치하는지 확인하고 필요 시 갱신한다.
#### 테스트 결정
fixture comparison은 SDD S04 evidence의 핵심 검증이다. 이 test가 실패하면 `monthly-bars` task와 `S04`는 완료로 볼 수 없다.
#### 중간 검증
```bash
go test ./services/worker/internal/marketdata/aggregation -count=1
```
## 최종 검증
```bash
go test ./services/worker/internal/marketdata/aggregation -count=1
go test ./services/worker/internal/marketdata/...
go test ./services/worker/...
git diff --check
```
기대 결과: 모든 명령 exit code 0. `TestAggregateDailyToMonthlyFixtureComparison`은 expected fixture의 OHLCV와 provenance까지 실제로 비교해야 한다.
