## [Unreleased]

### Added
- `EdinetClient` for EDINET API v2 access (company search, filings, financial statements)
- `XBRLParser` with dual TSV/XBRL extraction paths
- FastMCP server with 4 tools (search, filings, statements, company info)
- Click CLI (`search`, `statements`, `serve`)
- Disk cache with owner-only file permissions
- Rate limiter (sync + async)
- J-GAAP / IFRS / US-GAAP detection
- Polars and pandas DataFrame export

### Known Limitations
- XBRL parsing uses first-match strategy per statement type; data split across multiple XBRL instance files within a single filing may be incomplete
- MCP server tools use synchronous I/O internally (acceptable for single-user, rate-limited usage)
