LineageLens

LineageLens tracks AI-assisted code insertions and links them to provenance context.

Operating Modes

Pure Local Mode (local, default)

• No backend setup required.
• Data is stored locally in VS Code storage (or optional workspace file mode).
• Best for individual and offline workflows.
• Start the extension from Command Palette (Ctrl+Shift+P) by running Start LineageLens.

Backend Mode (backend)

• Connects to your FastAPI backend for shared/team workflows.
• Enables backend ingest, auth, search, and lineage graph capabilities.

Switch from Pure Local to Backend Mode

1. Start your backend service (default: http://127.0.0.1:8787).
2. In VS Code, open Command Palette (Ctrl+Shift+P).
3. Run AI Provenance: Switch to Backend Mode.
4. Run AI Insertion Detector: Backend Login and authenticate.
5. Optional: set backend endpoints in Settings if different from defaults.
