 ## Recent Change Log Summary
 
+- 2026-06-12 :: REQ-073 Approved → **Implemented** (confirm-req-implemented, BAT-037): `available_slots: int|null` capacity hint 추가. AC-3 반전·AC-6 신규. 16 tests passed (AC-6 3개 포함), 423 전체 회귀 없음. Blocking Issues 없음.
 - 2026-06-12 :: REQ-073 change-req (CHG-20260612-01): 응답 payload 에 `available_slots: int|null` 추가. AC-3 반전(available_slots 포함), AC-6 신규(hint 값 규칙). BAT-035 AC-3 evidence 무효 → Implemented → **Approved** 되돌림. 차기 batch 구현·검증 후 복귀.
 - 2026-06-11 :: REQ-058 change-req (CHG-20260611-01): `reconcile_universe` 슬롯 생성 시 `symbol` 누락 수정. 시그니처 `set[str]` → `dict[str, str]`(portfolio_id→symbol), INSERT에 symbol 포함, `symbol IS NULL` 기존 슬롯 backfill 추가. AC-5 신규 추가. 기존 AC 1~4 evidence 유효 → **Implemented 유지**.
 - 2026-06-11 :: BAT-035/036 완료 — REQ-073/074/075/021/034/063/048/005 Approved → **Implemented**, REQ-028 → **Deprecated** (trex.snapshot.req 코드 삭제·trex.slots.req 대체)
 - 2026-06-11 :: REQ-028 Implemented → **Deprecated** (BAT-035, dcy-025): `trex.snapshot.req` envelope (`assets[]`/`View`/`build_snapshot_envelope`) 코드 삭제 완료. 후속 표면은 REQ-073/074 (`trex.slots.req`) 로 대체.
-- 2026-06-11 :: REQ-073/074/075 신규 생성(Proposed) + REQ-021/034/063 change-req Implemented→**Approved** + REQ-028 폐기 예정 forward-link (draft-req, dcy-025 전략 read 표면 재설계): `trex.snapshot.req`→`trex.slots.req` 즉시 교체 RPC 계약(요청 {filter: status 단일, spy}, 응답 {slots[], degraded/reason/message}, strategy 제외)(REQ-073), 슬롯 단일 행 스키마(asset_quantity hub 정본+qty 미러+warned, cash_balance+cash_estimated, watchdog nested, paused — 필드별 정본 라벨)(REQ-074), baseline 정합(REQ-075). 토폴로지 큐 교체(REQ-021 CHG-01), 워치독 터치=slots.req 기본/spy 무터치·행 흡수(REQ-034 CHG-01), 운영자 CLI 새 표면+spy(REQ-063 CHG-01). REQ-028 은 keep-current + delivery 배치에서 Deprecated 전환(REQ-005 선례). 전략 모듈 lockstep cutover 필요. Next ID: REQ-076.
-- 2026-06-11 :: REQ-048/005 change-req (dcy-024 safety-sell 비활성화 모드/issue #15, CHG: 048-20260611-01·005-20260611-01): per-instance TOML `safety_sell_enabled: bool=True`(env 제외, REQ-048 AC-10) + `daemon.start()` 조건부 워커 게이팅(false 시 `trex-safety-sell` 미기동·물리 차단) + 기동 로그 `no autonomous liquidation` 경고 + runtime-flows(REQ-005 AC-5/6). `ExecutionService`·운영자 exit/cancel·kill-switch·전략 sell intent 불변. 모드는 기동 로그만 노출(스냅샷 응답 미포함, OQ-3). **신규 REQ 없음**(change-req only, dcy-024 OQ-1). 둘 다 Implemented→**Approved**, 차기 batch 구현·검증 후 복귀.
