feat(core-B): 운영자 sync/verify CLI + cold-start onboarding (BAT-051, REQ-105/106, PR #32)

dcy-034 마지막 조각. sync(슬롯 qty←브로커+warning해제+OQ-A 전이엣지+FR-7 평단seed)/verify(C 재대조·강제해제없음). core-A QC minor 2건 정리 동봉. QC(opus) PASS, 683 passed.

+# BAT-051 Design
+
+- Status: done
+- Batch: BAT-051
+
+## 1. 전이 엣지 추가 (OQ-A)
+
+### 결정: `_SYNC_TRANSITIONS` + `ALLOWED_TRANSITIONS` 확장
+
+```python
+# state.py 추가
+_SYNC_TRANSITIONS: frozenset[tuple[SlotState, SlotState]] = frozenset(
+    {
+        (SlotState.INACTIVE, SlotState.HOLDING),  # OQ-A: cold-start onboarding (actor=sync)
+    }
+)
+
+ALLOWED_TRANSITIONS = (
+    _BASE_TRANSITIONS | _TO_ERROR_TRANSITIONS | _FROM_ERROR_TRANSITIONS | _SYNC_TRANSITIONS
+)
+```
+
+- `_SYNC_TRANSITIONS`는 `ALLOWED_TRANSITIONS`에 포함(SlotService.transit_slot이 허용 체크함)
+- actor=sync, reason=onboarding 으로 transition_log에 식별 가능하게 기록
+- 일반 전략 경로(INACTIVE→PENDING_BUY)는 그대로 유지
+- wire 무영향: SlotState enum 5개 불변, slots RPC 상태값 변화 없음
+
+### actor 제한 구현
+
+SlotService.transit_slot은 `is_allowed_transition`만 체크하고 actor를 검증하지 않는다.
+actor 제한은 **호출 레이어(sync 함수)** 에서 강제: `sync_slot_to_broker`만 이 전이를 호출하고,
+일반 전략 경로(IntentService._admit_buy)는 INACTIVE→PENDING_BUY를 사용한다.
+transition_log에 `actor="sync"`, `reason="onboarding"` 으로 사후 감사 가능.
+
+## 2. PortfolioHubCostBasisPort (FR-7)
+
+```python
+# application/ports.py 추가
+class PortfolioHubCostBasisPort(Protocol):
+    """FR-7: portfolio-hub WAC read port (REQ-043 GET /v1/portfolios/{id}/holdings/cost-basis)."""
+    def get_cost_basis(self, portfolio_id: str) -> Optional[float]:
+        """Return WAC avg_price or None (degrade gracefully)."""
+        ...
+```
+
+- 어댑터: `adapters/portfolio/hub_read.py`에 `get_cost_basis` 메서드 추가
+- graceful degrade: 포트 없음(None) 또는 예외 → 수량만 갱신 + WARN
+
+## 3. sync_slot_to_broker (application/reconciliation.py)
+
+```python
+def sync_slot_to_broker(
+    *,
+    slot_id: str,
+    slot_repo,
+    slot_service,
+    broker: BrokerPort,
+    instance_key: str,
+    warn_store: ReconcileWarningStore,
+    cost_basis_port=None,  # Optional[PortfolioHubCostBasisPort]
+    dry_run: bool = False,
+) -> dict:
+    """
+    Returns: {
+        "slot_id": str,
+        "symbol": str,
+        "portfolio_id": str,
+        "before": {"qty": ..., "status": ..., "avg_price": ...},
+        "after": {"qty": ..., "status": ..., "avg_price": ...},
+        "warning_cleared": bool,
+        "dry_run": bool,
+        "skipped": bool,  # 브로커-only 슬롯(자동 편입 금지) — 해당 안됨(슬롯 있으므로)
+        "unmanaged": bool,  # 브로커에만 있고 슬롯 없음 → 미편입 경고
+    }
+    """
+```
+
+### 동작 흐름
+1. `fetch_slot(slot_id)` → 슬롯 확인
+2. `broker.get_balance()` → 해당 symbol 수량(bq)
+3. bq == 0: 슬롯 qty가 0 또는 None → WARN, skip (A 케이스 보호)
+4. bq > 0:
+   - INACTIVE 슬롯: `transit_slot(INACTIVE→HOLDING, actor="sync", reason="onboarding")`
+     + qty=bq, avg_price=cost_basis(if available)
+   - HOLDING 슬롯: qty만 갱신(slot_service 직접 update 또는 transit_slot 재진입 없이 update_slot)
+   - PENDING_* 슬롯: skip + WARN (in-flight, 수정 불가)
+5. 갱신 후 slotqty == bq → `clear_warned(slot_id)`
+6. dry_run: 실제 쓰기 없이 before/after 예상치 반환
+
+## 4. verify_slot_reconcile (application/reconciliation.py)
+
+```python
+def verify_slot_reconcile(
+    *,
+    portfolio_id: str,
+    store: SnapshotStore,
+    broker: BrokerPort,
+    slot_repo,
+    instance_key: str,
+    warn_store: ReconcileWarningStore,
+) -> dict:
+    """
+    Returns: {
+        "portfolio_id": str,
+        "slot_id": str | None,
+        "result": "cleared" | "rejected" | "not_c_case" | "not_warned" | "slot_not_found",
+        "hub_qty": int,
+        "broker_qty": int,
+        "reason": str | None,
+    }
+    """
+```
+
+### 동작 흐름
+1. `slot_repo.find_slot_by_portfolio(instance_key, portfolio_id)` → 슬롯 확인
+2. `warn_store.is_warned(slot_id)`:
+   - False → "not_warned" (이미 해제, 0 종료코드)
+   - True → warn_store.get_case_code() 필요 → 단순화: list_warned_with_meta 또는 is_warned의 리턴값 확장
+   
+### case_code 조회 설계
+`ReconcileWarningStore.get_warning_info(slot_id)` 추가:
+```python
+def get_warning_info(self, slot_id: str) -> Optional[dict]:
+    """Returns {"portfolio_id", "case_code", "actor", "reason"} or None."""
+```
+InMemoryReconcileWarningStore는 `_warned[slot_id]` dict 반환.
+PostgreSQLReconcileWarningStore는 SELECT 1행 반환.
+
+3. case_code != 'C' → "not_c_case" + 안내 + 0 종료코드
+4. `reconcile_positions`(store, broker) 재실행 → hub_qty, broker_qty 대조
+5. 일치: `clear_warned(slot_id)` → "cleared"
+6. 불일치: warning 유지 → "rejected" + hub_qty/broker_qty/차이 + 비-0 종료코드
+
+## 5. CLI 서브커맨드 (runtime/cli.py)
+
+### sync
+```
+trex-core sync [--portfolio-id <pid>] [--all] [--dry-run] [--yes] [--live] [--json]
+              [--config <toml>] [--instance <key>]
+```
+- `--portfolio-id` 또는 `--all` 중 하나 필수
+- direct-DB: `PostgreSQLReconcileWarningStore`, `BrokerPort`(KIS/paper), `slot_repo`
+- broker/slot_repo 조립은 `DaemonConfig`에서 구성
+
+### verify
+```
+trex-core verify [--portfolio-id <pid>] [--json]
+               [--config <toml>] [--instance <key>]
+```
+- `--portfolio-id` 없으면 모든 C-warned 슬롯 일괄 재대조
+- direct-DB + read-중심
+
+## 6. Cross-service 영향
+
+- `(INACTIVE, HOLDING)` 전이 추가: wire 상태값 불변, trex-orb-v1/tsl-v1 영향 없음
+- slots RPC 필드 변경 없음 (reconcile_warned 필드는 BAT-050에서 이미 추가됨)
+- `PortfolioHubCostBasisPort`: portfolio-hub REQ-043(`GET /v1/portfolios/{id}/holdings/cost-basis`) 의존. graceful degrade로 미가용 시 동작은 유지됨.
+
+## 7. ReconcileWarningStore 확장
+
+기존 Protocol에 `get_warning_info` 추가:
+```python
+def get_warning_info(self, slot_id: str) -> Optional[dict]:
+    """Return {"portfolio_id", "case_code", "actor", "reason"} or None."""
+    ...
+```
+- InMemoryReconcileWarningStore: `_warned.get(slot_id)` 복사본 반환
+- PostgreSQLReconcileWarningStore: SELECT row → dict 반환
+- 기존 메서드 시그니처 불변 (additive)

+
+## 핵심 구현 결정
+
+### 1. 전이 엣지 (OQ-A)
+- `_SYNC_TRANSITIONS = frozenset({(INACTIVE, HOLDING)})`를 `state.py`에 추가
+- `ALLOWED_TRANSITIONS`에 합집합으로 포함 (13→14개)
+- actor 제한은 호출 레이어: `sync_slot_to_broker`만 이 전이를 호출, transition_log에 `actor="sync"` `reason="onboarding"` 기록
+- SlotState enum 5개 불변, wire 계약 무영향
+
+### 2. sync 동작
+- INACTIVE + broker_qty > 0: `transit_slot(INACTIVE→HOLDING, actor="sync", reason="onboarding")`
+- HOLDING + qty 불일치: `update_slot` 직접 (transit_slot 재진입 없음)
+- PENDING_*: skip + WARN (in-flight 보호, NFR-3)
+- broker_qty == 0: skip + WARN (A-case guard)
+- after qty == broker_qty: `clear_warned(slot_id)` → `warning_cleared=True`
+
+### 3. verify 동작
+- `get_warning_info(slot_id)` 로 case_code 확인
+- case_code != 'C': `not_c_case` + 0 종료 (OQ-C)
+- hub_qty vs broker_qty: snapshot_store vs broker.get_balance()
+- 일치: `clear_warned` + `store.set_warning(False)` → "cleared"
+- 불일치: warning 유지 → "rejected" + 사유 (강제 해제 없음)
+- 슬롯 qty 변경 없음 (read-centric 불변)
+
+### 4. core-A QC cleanup
+- `intents.py`의 `_check_reconcile_warned` 제거: 실제 게이트는 `_admit_buy`/`_admit_sell`에 인라인으로 구현돼 있었음 (BAT-050)
+- `reconciliation.py` module docstring: case_code='B'/'C' 설명 명확화
+
+### 5. CLI sync guard
+- `--portfolio-id` 또는 `--all` 중 하나 필수
+- dry-run 아닐 때: `--yes` 필수 (확인 프롬프트)
+- live 계좌: `--yes --live` 이중 확인
+- verify: read-centric이므로 `--yes`/`--live` 게이트 없음

+
+## Scope
+
+### REQ-105 (sync)
+- `trex-core sync [--portfolio-id <pid> | --all]` 서브커맨드 (direct-DB, pause/resume 방식)
+- 대상: portfolio-hub 유니버스에 있어 슬롯이 생성된 종목(B-warned + INACTIVE 포함)
+- 동작: 슬롯 qty ← 브로커, INACTIVE + broker qty>0 → HOLDING 전이(actor=sync, reason=onboarding)
+- avg_price seed: PortfolioHubCostBasisPort(`GET /v1/portfolios/{id}/holdings/cost-basis`) — graceful degrade
+- 갱신 후 qty 일치 시 `clear_warned`
+- --dry-run, --yes, --live 이중 확인 게이트
+- before/after 출력
+
+### REQ-106 (verify)
+- `trex-core verify [--portfolio-id <pid>]` 서브커맨드 (direct-DB)
+- 동작: `reconcile_positions` 재사용(브로커 경유 2-대조), 일치 → clear_warned, 불일치 → 거부
+- read-중심: 슬롯 qty 변경 없음
+- C 전용: B-warned 슬롯에 호출 시 "C 케이스 대상 아님" + 0 종료코드
+- --json 출력 지원
+
+### OQ-A 전이엣지
+- `ALLOWED_TRANSITIONS`에 `(INACTIVE, HOLDING)` 추가
+- `_SYNC_TRANSITIONS` 별도 집합(sync/onboarding actor 제한 용도)
+- 일반 전략 경로(INACTIVE→PENDING_BUY→HOLDING) 유지
+
+### core-A QC cleanup
+- `intents.py` `_check_reconcile_warned` 죽은 메서드 제거
+- `reconciliation.py` docstring 혼동 문구 수정
+
+## 파일 영향
