Scaffold New Lumen Module

Generate a new module following existing patterns. Follow all rules in CLAUDE.md.

Before Scaffolding

1. Read src/types/index.ts — check if needed types already exist
2. Identify the layer:
   • store/ — SQLite CRUD for a table (see templates/store.ts.md)
   • ingest/ — content extractor for a source type (see templates/ingest.ts.md)
   • search/ — search signal implementation
   • chunker/ — format-specific chunker
   • compress/ — compression pipeline stage
   • graph/ — graph algorithm
   • delta/ — change tracking
3. Check if a stub file already exists (many have placeholder comments)

Steps

1. Add new types to src/types/index.ts if needed
2. Create the module following the template in templates/
3. If store module: add the table to src/store/schema.ts and bump CURRENT_VERSION
4. If ingest module: wire into src/ingest/file.ts router
5. Run npx tsc --noEmit to verify
6. Run npx prettier --write on new files
