Analyze Object

Single entry point for the Lithic decision pipeline. The UI renders exactly what POST /api/v1/analyze-object returns. No client-side computation.

Viewer selection (adapter v0.1)

Paste a viewer-emitted selection (object_id, category, family, type, parameters). The adapter performs exact field mapping — no defaults, no inference. Result is loaded into the analyze input below.
