Summary

Implements the SQLite persistence layer with schema for events, sessions, ingestion state, and patterns.

  • storage.py with SQLiteStorage class:
    • Events table with denormalized fields for fast queries
    • Sessions table for session metadata
    • Ingestion state tracking for incremental updates
    • Patterns table for pre-computed insights
    • Indexes on timestamp, session_id, tool_name, project_path
  • Data classes: Event, Session, IngestionState, Pattern
  • CRUD operations for all entities with batch insert support
  • get_db_stats() for monitoring database health
  • Updated server.py to use storage for get_status()
  • Comprehensive test suite (16 tests)

Test plan

  • make check passes (fmt, lint, test)
  • All 16 tests pass
  • Database created at ~/.claude/contrib/analytics/data.db
