## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G06_0.log` | `code_review_cloud_G06_0.log` | FAIL | max daily/open guard, risk rejected order/decision surface, Dart parser map drift 보완 필요 |
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | FAIL | same-account concurrent submit이 broker 전 count limit을 원자적으로 보장하지 못함 |
| `plan_cloud_G07_2.log` | `code_review_cloud_G07_2.log` | FAIL | account mutex 대기 전 stale risk snapshot과 nil broker unavailable precedence 보완 필요 |
| `plan_cloud_G07_3.log` | `code_review_cloud_G07_3.log` | PASS | queued submit이 최신 risk state를 보고 nil broker가 risk보다 먼저 unavailable을 반환함 |

## 구현/정리 내용

- live trading risk policy, default halted kill switch, broker 전 risk evaluation, rejected order + `LiveRiskDecision` response surface를 추가했다.
- worker/API/CLI/client contract parser and operator output surface를 live risk/kill switch 메시지에 맞춰 정렬했다.
- same-account submit을 account별 mutex로 직렬화해 risk usage 계산부터 broker result 저장까지 count-limit race를 막았다.
- account mutex 대기 후 최신 policy/kill switch를 snapshot하도록 조정하고, nil broker check를 validation 직후로 이동해 unavailable contract를 유지했다.

## 최종 검증

- `gofmt -l services/worker/internal/livetrading/service.go services/worker/internal/livetrading/service_test.go` - PASS; output empty
- `go test ./services/worker/internal/livetrading -run 'TestSubmitLiveOrder(QueuedKillSwitchBlocksBeforeBroker|Concurrent(MaxOpenOrders|MaxDailyOrders))' -count=1 -v` - PASS; queued kill switch and concurrent max open/daily tests passed
- `go test ./services/worker/internal/livetrading -run 'TestSubmitLiveOrderBrokerUnavailableWithDefaultKillSwitch|TestSubmitLiveOrderBrokerUnavailable' -count=1 -v` - PASS; nil broker unavailable precedence tests passed
- `go test ./services/worker/internal/livetrading` - PASS; package tests passed
- `go test ./services/worker/...` - PASS; worker module tests passed
- `bin/lint` - PASS; exit code 0 with existing Mattermost `avoid_print` info only
- `go test -race ./services/worker/internal/livetrading -run 'TestSubmitLiveOrder(QueuedKillSwitchBlocksBeforeBroker|Concurrent(MaxOpenOrders|MaxDailyOrders)|BrokerUnavailableWithDefaultKillSwitch)' -count=1` - PASS; focused race check passed
