Architecture: - Moved backend/app/ to diligence/ Python package - Dialect-agnostic models (Uuid + JSON, no PostgreSQL imports) - Auto-detect database: empty DATABASE_URL → SQLite at ~/.diligence/data.db - Cross-dialect migrations (inspector-based, no raw PostgreSQL DDL) - FastAPI serves pre-built React frontend for pip path - CLI entry point: diligence [--port] [--no-browser] [--data-dir] - pyproject.toml with optional deps: [postgres], [mcp], [dev] - Docker path unchanged: docker compose up -d pip install path: pip install . && diligence Docker path: ./setup.sh && docker compose up -d
