+Library Documentation Generation:
+
+**Architecture** (after scope refactor):
+
+1. **Analysis Layer** (`@fuzdev/svelte-docinfo`):
+   - Pure TypeScript/Svelte source analysis
+   - API: `library_analyze({source_files, options}) → {modules: ModuleJson[]}`
+   - No package metadata, no output generation
+   - See `@fuzdev/svelte-docinfo/CLAUDE.md` for details
+
+2. **Type Layer** (`@fuzdev/fuz_util`):
+   - Shared type definitions: `SourceJson`, `LibraryJson`, `ModuleJson`, `DeclarationJson`
+   - Metadata parsing: `library_json_parse(package_json, source_json)`
+   - GitHub/npm URL generation
+
+3. **Integration Layer** (fuz_ui):
+   - `library_gen.ts` - Gro genfile that orchestrates generation
+   - `library_output.ts` - generates library.json and library.ts wrapper
+   - Uses `library_analyze()` from svelte-docinfo for analysis
+   - Wraps results with `SourceJson` from fuz_util
+   - Generates output files with GitHub/npm metadata via `LibraryJson`
+
+4. **Runtime Layer** (fuz_ui):
+   - `library.svelte.ts` - `Library` class wraps `LibraryJson` with reactive properties
+   - `module.svelte.ts` - `Module` class wraps `ModuleJson`
+   - `declaration.svelte.ts` - `Declaration` class wraps `DeclarationJson`
+   - Used by documentation UI components
+
+**Flow**:
+```
+source files → library_analyze() → modules[]
+modules[] → wrap with SourceJson → library_json_parse()
+→ LibraryJson → library_generate_output() → library.json + library.ts
+```
