feat: company metadata 안정화 — 실제 sector/industry/exchange 보강
...
- CompanyMetadataService 신규: Redis → registry → yfinance 순서 조회,
semaphore(5) 보호, 24h cache, companies + registry UPSERT
- GET /company/{ticker} + POST /company/bulk (최대 100개, 세션 격리)
- companies 테이블에 exchange/country/market_cap 컬럼 추가 (alembic)
- CompanyInfo 스키마 exchange/country/market_cap 필드 추가
- _is_placeholder() 체크: 기존 "Technology/Software/XYZ Corporation" 행 재보강
- financial endpoint: financials/price 실패 시 company block은 유지 (500 방지)
- bulk endpoint: 각 ticker마다 독립 AsyncSession으로 동시 세션 충돌 방지
- scripts/backfill_registry_sector.py: 9376개 NULL-sector 일괄 보강 스크립트
검증: AU→Basic Materials, USAS→Basic Materials, CPRX→Healthcare,
HE→Utilities, ACHR→Industrials, ZZZZZZ→404, AAPL 기존 데이터 유지

feat: multi-ticker bulk bars endpoints + BF-B ticker normalization
...
- GET /api/v1/price/data?tickers=AAPL,MSFT,BF-B&start_date=...&end_date=...
→ multi-ticker daily OHLCV via Alpaca (ORB engine daily bars interface)
- GET /api/v1/alpaca/intraday?tickers=...&interval=5min&start_date=...&end_date=...
→ multi-ticker intraday OHLCV via Alpaca (ORB engine ORB-window interface)
- AlpacaMultiBarsResponse schema: {source, interval, count, bars: {sym → [bar]}}
- normalize_ticker(): BF-B→BF.B, BRK-B→BRK.B applied in get_bars/get_multi_bars/get_snapshot(s)
- get_multi_bars: transparent batching (200 symbols/request) + INTERVAL_MAP aliases (5min, 15min, 60min, …)
- Response re-keys Alpaca normalized symbols back to original input names

- AlpacaClient.get_snapshot / get_snapshots 메서드 추가
- AlpacaSnapshotResponse / AlpacaMultiSnapshotResponse 스키마 추가
- docs/PYTHON_CLIENT.md 사용 예시 업데이트

fix: GET /price/data/{ticker} — start/end alias 지원 + 단일 날짜 조회 허용
...
- ?start=&end= 쿼리 파라미터를 start_date/end_date의 alias로 수용
- end_date <= start_date 검증을 end_date < start_date 로 완화하여 당일(start==end) OHLCV 조회 가능

Codebase improvements: caching decorator, Pydantic v2, DB indexes, connection pooling, Alembic
...
- Add @with_cache() decorator to eliminate ~15-line caching boilerplate per endpoint
- Apply decorator to 8 existing endpoints (stocks, alpaca, finra) and add caching
to 6 previously uncached endpoints (news, etf, filings) with appropriate TTLs
- Migrate all @validator to @field_validator (Pydantic v2), deduplicate validation
logic into shared functions in validators.py
- Fix datetime.utcnow() → datetime.now(timezone.utc), remove unused uuid import
- Convert ErrorLogResponse class Config → model_config = ConfigDict(...)
- Add health check exception logging instead of silent pass
- Add data_source indexes to PriceData and FinancialData tables
- Initialize Alembic with async engine configuration
- Add persistent HTTP sessions for SEC client (aiohttp) and FRED proxy (httpx)
- Add response_model schemas for Alpaca bars/intraday and news-only/social-only

Add Alpaca-specific DB table and Redis caching for Alpaca/FINRA endpoints
...
Separate Alpaca price data into dedicated AlpacaPriceData table to avoid
UniqueConstraint('ticker', 'date') conflicts with Yahoo Finance PriceData.
Add Redis caching (build_cache_key/get_cached_response/set_cached_response)
to 3 Alpaca endpoints and 2 FINRA query endpoints with appropriate TTLs.
