genichinandClaude Opus 4.8 a4e263c8e7 Deliver BAT-002: slot-core daemon + HTTP intent API + PostgreSQL 
Implement REQ-005~009 (dcy-002 slice 1) as an onion stack on top of the
BAT-001 pure domain:
- application: IntentService (admission + single-writer transition +
  intent_id idempotency via durable intent_log)
- adapters/persistence: PostgreSQLSlotRepository + PostgreSQLIntentStore +
  trex-core-owned migrations (daily_slot per Appendix A, daily_symbol_entries,
  slot_transition_log, intent_log) + in-memory intent store
- adapters/api: FastAPI /v1 (healthz, intents/buy|sell|{id}, slots, capacity)
- runtime: trex-core-daemon entrypoint with lifespan migrate+preallocate

Verification (against local PostgreSQL 18): 74 passed, ruff clean, domain
import sweep shows zero web/db deps (NFR-1), 20-thread concurrency admits
exactly the idle count (NFR-2), idempotent resubmit causes no double
transition (NFR-3), EXPECTED_SLOT_FIELDS<->information_schema drift test
(realizes dcy-001 OQ-2's deferred DB-side check), and a daemon E2E smoke.

Align all four baseline docs to the new daemon/API/persistence layers.
BAT-002 -> release-candidate; REQ-005~009 -> Implemented. Full async outbox,
broker execution, safety floor, and strategy daemons remain deferred to a
follow-up Discovery.

req-008: 슬롯 read-only 조회 HTTP API

  • Status: Implemented
  • Type: Interface
  • Priority: High
  • Owner: project maintainers

Intent

  • 매도 전략이 보유 슬롯을 평가하고 운영자가 가용성을 모니터링할 수 있도록, 코어가 슬롯 스냅샷과 capacity 를 read-only 로 제공한다.

Requirement

  • GET /v1/slots?status=holding(status/trading_date 필터)로 슬롯 스냅샷을 read-only 로 반환하고, GET /v1/capacity 로 idle/holding/pending 카운트 + scarcity_ratio 를 반환한다. 이 엔드포인트는 슬롯을 쓰지 않는다(read-only).

Acceptance Criteria

  1. Given holding 슬롯이 있는 상태, When GET /v1/slots?status=holding, Then 해당 슬롯 스냅샷 목록을 반환한다(쓰기 부작용 없음).
  2. Given status/trading_date 필터, When 조회, Then 필터에 맞는 슬롯만 반환한다.
  3. Given 슬롯 분포, When GET /v1/capacity, Then idle/holding/pending 카운트와 scarcity_ratio 를 반환한다.

Impacted Area

  • Docs: docs/interface-contract.md(조회 API 계약) — REQ-009 에서 정합
  • Modules: trex_core/ 하위 API 어댑터(읽기 라우터); 도메인 compute_slot_capacity/repo 조회 재사용
  • Tests: 조회 API 통합테스트

Notes

  • 엔드포인트 집합은 dcy-002 OQ-3 결정. REQ-005(런타임)·REQ-006(영속화) 선행.
  • read-only 라 단일 writer 불변식과 무관(쓰기 경로 아님).
  • 출처: dcy-002 FR-3.
