feat(bat-053): 그날-시작 KIS 인증정보 fetch + fail-safe 로드 (REQ-112~115)

REQ-112: BrokerCredentialPayload/TradingContext 데이터클래스 + PortfolioHubReadPort.fetch_broker_credential() 포트 메서드 + hub_read 어댑터(_fetch_user_info 헬퍼 추출) + stub_read 결정론 stub
REQ-113: DaemonInstanceConfig/DaemonConfig.credential_fetch_enabled opt-in(기본 False) + TOML 파싱 + break-glass(TREX_KIS_BROKER_BREAK_GLASS) 감지
REQ-114: SnapshotScheduler._maybe_fetch_credential() — fail-closed 3조건(unavailable/broker-null/trading_disabled) + CRITICAL 알람 DAY_START_LOAD_FAILED + IntentService entry_allowed_fn 게이트(BuyIntent 차단, SellIntent 통과)
REQ-115: 그날 고정 캐시(_cached_credential/_credential_date) — 동일 날짜 재fetch 방지 + app_secret 메모리 한정(Redis 미기록)

스텁 기반 구현: 실 portfolio-hub/네트워크 없이 AC 전부 단위 테스트.
회귀: credential_fetch_enabled=False(기본) 경로 byte-for-byte 보존.
745 passed, 47 skipped (0 failed).

+# BAT-053: Design
+
+## Key Design Decisions
+
+### D1: `entry_allowed` 상태 위치 — SnapshotScheduler + 공유 callable
+
+**결정**: `SnapshotScheduler`에 `entry_allowed: bool = True` (opt-in=False 기본 통과) 상태를 두고, IntentService에 `entry_allowed_fn: Callable[[], bool] | None` 게이트를 주입한다.
+
+**근거**:
+- `entry_allowed`는 그날-시작 체크포인트(SnapshotScheduler.run_once())에서 설정되므로 소유자는 SnapshotScheduler가 자연스럽다.
+- IntentService는 이미 `warn_store`, `max_active_slots` 등 주입형 게이트 패턴을 사용한다. 동일 패턴으로 `entry_allowed_fn: Optional[Callable[[], bool]] = None`을 추가하면 기존 코드 변경 최소화.
+- `entry_allowed_fn=None`(기본)이면 게이트 완전 통과 → `credential_fetch_enabled=False`(기본)일 때 기존 동작 byte-for-byte 보존(회귀 0).
+- daemon.py에서 `scheduler.get_entry_allowed` 메서드를 `IntentService`에 주입하는 방식으로 조립.
+
+**대안 검토**:
+- 별도 `DayStartState` 객체: 추가 클래스 생성 필요, SnapshotScheduler와 결합 불필요하게 증가.
+- IntentService 내부 setter: 의존 방향 역전(application이 application 내부를 조율하는 순환 구조) — 거부.
+
+### D2: `credential_fetch_enabled` 플래그 전파 경로
+
+**결정**: `DaemonInstanceConfig.credential_fetch_enabled: bool = False` → `DaemonConfig.from_config()`에서 `inst.credential_fetch_enabled`를 읽어 `DaemonConfig.credential_fetch_enabled: bool = False`에 설정. `SnapshotScheduler` 생성자에 `credential_fetch_enabled: bool = False` 인자 추가.
+
+**근거**:
+- TOML → `DaemonInstanceConfig` → `DaemonConfig` → `SnapshotScheduler` 흐름이 기존 `safety_sell_enabled`, `watchdog_timeout_sec` 패턴과 동일. 일관성 유지.
+- `from_env()` 는 변경 없음(always `False`). `from_config()`만 TOML 값을 읽어 전파.
+
+### D3: REQ-113 fetch 소스 우선순위 구현 위치
+
+**결정**: 우선순위 로직은 `DaemonConfig.from_config()`에 두지 않고 **`SnapshotScheduler.run_once()`의 그날-시작 후크**에 둔다.
+
+**근거**:
+- REQ-113 Notes: "`base_url`/timeout/allow_live는 env 유지". fetch는 app_key/app_secret/account_ref만 가져온다.
+- `DaemonConfig.from_config()`는 정적 구성 해결 단계 — 네트워크 I/O(fetch)를 여기에 두면 의존성 역전 위반(runtime이 portfolio-hub를 직접 호출).
+- `SnapshotScheduler.run_once()`는 이미 portfolio-hub를 호출하는 지점이고, `credential_fetch_enabled=True`일 때 추가 fetch가 자연스럽다.
+- break-glass(`TREX_KIS_BROKER_BREAK_GLASS=true`) 감지는 `SnapshotScheduler` 초기화 시 `os.environ`을 읽어 `_break_glass: bool` 플래그로 보관.
+- fetch 결과(`BrokerCredentialPayload`)는 `SnapshotScheduler._cached_credential`에 그날 고정 캐시.
+- **KISConfig 재조립 경로**: `SnapshotScheduler`에 `kis_config_callback: Optional[Callable[[BrokerCredentialPayload], None]]`를 주입. daemon.py에서 이 callback이 `KISBroker`를 재초기화하거나 config를 갱신하는 역할을 한다. 단, M3에서 중장기 인스턴스 추가 전까지는 단기 07:30 로드에서만 필요하고, BAT-053 범위에서는 `entry_allowed` 플래그 설정 + 알람까지만 구현. KISBroker 재조립은 M3 별도 batch.
+
+**BAT-053 범위 명확화**:
+- REQ-113 AC-1~7 중 AC-2(fetch 결과로 KISConfig 구성)의 "KISBroker에 실제 적용" 부분은 M3 KISBroker 재조립 batch에 defer. 이번 batch에서는 fetch→캐시→entry_allowed 게이트 + 알람까지.
+- 단, AC-2 테스트는 TradingContext가 올바르게 반환됨을 stub으로 검증.
+
+### D4: 그날 고정 캐시 설계 (REQ-115)
+
+**결정**: `SnapshotScheduler`에 인스턴스 변수 추가:
+- `_cached_credential: Optional[BrokerCredentialPayload] = None`
+- `_credential_date: Optional[date] = None`
+- `_entry_allowed: bool = True` (opt-in=False면 항상 True = 차단 안 함)
+
+`run_once()` 시 `credential_fetch_enabled=True`이면 `_maybe_fetch_credential()` 메서드 호출.
+`_maybe_fetch_credential()`:
+1. `_credential_date == today` → 그날 고정 캐시 반환(재fetch 안 함, REQ-115 AC-3)
+2. break-glass → env-only, 캐시 없음, `_entry_allowed=True`
+3. `fetch_broker_credential()` 호출 → 성공: 캐시 + `_entry_allowed=True`; 실패(3가지 조건): `_entry_allowed=False` + ERROR + CRITICAL 알람
+
+`get_entry_allowed() -> bool` 메서드 노출 → daemon.py에서 IntentService.`entry_allowed_fn`에 주입.
+
+### D5: 중장기 인스턴스 후크 위치 (REQ-114 Notes)
+
+**결정**: BAT-053에서는 단기 07:30 KST 경로(SnapshotScheduler.run_once())만 구현. 중장기 인스턴스(dcy-027 리밸런싱 주기)의 동등 후크는 BAT-053 구현 후 그 위치를 확인하고 설계에 명시. 현재 코드상 중장기 후크는 SnapshotScheduler._maybe_tick()과 run_once()를 공유하므로 `credential_fetch_enabled=True`이면 동일 경로로 처리됨. dcy-027 추가 인스턴스가 별도 run_once() 트리거 주기를 가질 경우 그때 조정.
+
+### D6: AlarmEmitter `DAY_START_LOAD_FAILED`
+
+**결정**: AlarmEmitter 자체는 변경 없음(코드는 문자열 파라미터로 전달). `SnapshotScheduler`에서 `self._alarm_emitter.publish_alarm("DAY_START_LOAD_FAILED", ...)` 직접 호출. ALARM-INVENTORY.md 또는 별도 코드 상수 추가는 BAT-053 범위 외(dcy-033/REQ-100 패턴 재사용).
+
+## Module Interface Summary
+
+### `application/portfolio.py` 추가
+```python
+@dataclass(frozen=True)
+class BrokerCredentialPayload:
+    account_ref: str
+    app_key: str
+    app_secret: str

+```
+
+### `adapters/portfolio/hub_read.py` 변경
+- `whoami()` 내부 로직을 `_fetch_user_info() -> dict` 헬퍼로 추출

+
+### `adapters/portfolio/stub_read.py` 변경
+- `trading_context: Optional[TradingContext] = None` 생성자 인자 추가
+- `fetch_broker_credential()` stub 구현
+

+- 생성자: `entry_allowed_fn: Optional[Callable[[], bool]] = None` 추가
+- `_admit_buy()`: `entry_allowed_fn is not None and not entry_allowed_fn()` → reject `day_start_load_failed`
+
+### `runtime/daemon.py` 변경
+- `SnapshotScheduler` 생성 시 `credential_fetch_enabled=config.credential_fetch_enabled` 전달
+- `IntentService` 생성 시 `entry_allowed_fn=self.snapshot_scheduler.get_entry_allowed` 전달 → SnapshotScheduler가 먼저 생성되어야 함 (순서 조정 필요 확인)
+
+## Layer Compliance
+
+- `domain/` 변경 없음 — 도메인 순수성 불변
+- `application/portfolio.py`: 새 dataclass(frozen=True) — IO/네트워크 없음 (import sweep 통과)
+- `application/snapshot_scheduler.py`: portfolio 포트 호출(이미 포트 인터페이스) — 신규 import 없음
+- `application/intents.py`: callable 주입 — 추가 import 없음
+- `adapters/`: 구체 구현만 변경
+- `runtime/`: 조립 레이어 변경

+# BAT-053: Planning
+
+## Scope Summary
+
+그날-시작 시 portfolio-hub `/v1/user_info`에서 KIS 인증정보를 fetch하고, 실패 시 fail-closed로 신규 진입을 차단하며, 성공 시 그날 캐시로 KIS API 장중 연속성을 보장한다.
+
+4개 REQ 모두 같은 delivery 단위:
+- REQ-112: 트랜스포트 계층 (포트 인터페이스 + HTTP 어댑터 + stub)
+- REQ-113: 설정 계층 (TOML opt-in + fetch/break-glass/env-only 우선순위)
+- REQ-114: 그날-시작 로드 게이트 (fail-closed + 알람 + BuyIntent 차단)
+- REQ-115: 그날 고정 캐시 + 장중 무중단 NFR
+
+## Task Breakdown
+
+### T1: REQ-112 — 포트/어댑터 계층
+- `application/portfolio.py`: `BrokerCredentialPayload`, `TradingContext` 데이터클래스 + `PortfolioHubReadPort.fetch_broker_credential()` 포트 메서드 추가
+- `adapters/portfolio/hub_read.py`: `_fetch_user_info()` 헬퍼 추출 + `fetch_broker_credential()` 구현
+- `adapters/portfolio/stub_read.py`: `fetch_broker_credential()` stub 추가
+- 테스트: `tests/adapters/portfolio/test_hub_read.py` AC-1~7, `test_stub_read.py` AC-6
+
+### T2: REQ-113 — 설정 계층
+- `runtime/config.py`: `DaemonInstanceConfig.credential_fetch_enabled: bool = False` + `from_toml()` 파싱
+- `DaemonConfig.from_config()` 또는 new helper: fetch/break-glass/env-only 우선순위 로직
+- 테스트: `tests/runtime/test_instance_config.py` AC-1~7(추가)
+
+### T3: REQ-114 + REQ-115 — 그날-시작 게이트 + 그날 고정 캐시
+- `application/snapshot_scheduler.py`:
+  - `run_once()` 앞에 `credential_fetch_enabled=True` 경로에서 `fetch_broker_credential()` 호출
+  - `entry_allowed: bool` in-process 상태 + `_cached_credential: BrokerCredentialPayload | None` + `_credential_date: date | None`
+  - fail-closed 3 조건(PortfolioHubUnavailableError / broker None / trading_enabled False) → ERROR 로그 + CRITICAL 알람 DAY_START_LOAD_FAILED
+  - 그날 고정 — 장중 재fetch 방지
+- `application/alarm_emitter.py`: `DAY_START_LOAD_FAILED` 알람 코드 추가(기존 패턴 재사용 — 실제로 코드 자체는 문자열이므로 사용처 추가)
+- `application/intents.py` (IntentService): `entry_allowed` 게이트를 BuyIntent admission에 추가
+- 테스트: `tests/application/test_snapshot_scheduler.py` AC-1~9 + REQ-115 AC-1~6
+- 테스트: `tests/application/test_execution.py` 또는 test_intent 계열 AC-4, AC-5
+
+## Design Gate
+
+**design.md 필요함(standard profile)**: 다음 판단이 필요.
+1. `entry_allowed` 상태를 어디에 보관할지: SnapshotScheduler 내부 vs 별도 `DayStartState` 객체 vs IntentService에 주입.
+2. IntentService에 `entry_allowed` 게이트를 어떻게 연결할지(생성자 주입 callable vs setter vs 공유 객체).
+3. `credential_fetch_enabled` 플래그가 False(기본)일 때 기존 경로 byte-for-byte 보존 검증 방법.
+4. 중장기 인스턴스(dcy-027)의 그날-시작 후크 위치 확인(현 코드에서 run_once() 위치 분석 필요).
+5. `fetch_broker_credential()` 반환값이 `DaemonConfig.from_config()`에서 `KISConfig` 재조립으로 이어지는 흐름 설계.
+
+## Risks
+
+- R1: IntentService에 `entry_allowed` 게이트를 연결할 때 기존 pass-through 테스트 회귀 가능성 → `credential_fetch_enabled=False` 기본 경로에서 게이트를 비활성화하면 회귀 방지
+- R2: `app_secret` 로그 노출 — 마스킹 로직 누락 주의
+- R3: `stub_read.py`의 stub이 포트 인터페이스와 불일치 → pytest import sweep으로 조기 발견
+- R4: REQ-113의 `DaemonConfig.from_config()` 변경이 기존 `test_instance_config.py` 회귀 유발 가능 → AC-1(opt-in off → env-only, fetch 미호출) 케이스가 핵심 회귀 가드
+
+## Dependencies
+
+- portfolio-hub REQ-049 (dcy-010): `/v1/user_info` 확장 계약 — 머지 완료(미배포). 스텁 기반으로 실 portfolio-hub 없이 구현.
+- REQ-099/100 (dcy-033, BAT-049): AlarmEmitter `trex.alerts` 계약 — 이미 구현됨.
+- REQ-019: ledger_outbox 무손실 — 기존 구현 재확인(REQ-115 AC-2).
