I Luk Kim	9e2a8aba47	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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	5 months ago
I Luk Kim	d0f1a9a7d0	Add SEC filings indexing, search, and exhibit extraction (8-K, 6-K, 20-F, 40-F) ... Extract shared SECHttpClient from ETF fetcher (retry, backoff, cache, throttle) and apply it to both ETF and core SEC services, fixing missing rate limiting. Add SECFiling DB model, Pydantic schemas, SECFilingsService with auto-indexing, and REST endpoints at /filings/search, /filings/documents, /filings/exhibit.
