**Multiple lines**: Argument of type '"CHROMA_SYNC"' is not assignable to parameter of type 'Component'

**Fix**: Add 'CHROMA_SYNC' to Component type union or update logger calls

---

### 5. src/shared/config.ts (1 error)
**Line 11**: Cannot find name '__DEFAULT_PACKAGE_VERSION__'

**Fix**: This should be injected during build, check build configuration

---

**Line 173**: Type 'null' is not assignable to type 'SessionSearch'

**Fix**: Update test to handle nullable type properly

### 11. React/Viewer UI Files (100+ errors)

#### All .tsx files: Cannot use JSX unless '--jsx' flag is provided
This affects all viewer components but is expected - these are built with esbuild which handles JSX.

**Lines 66, 70**: `'data'` is of type 'unknown'

#### src/ui/viewer/hooks/useSettings.ts (5 errors)
**Lines 17-19**: `'data'` is of type 'unknown'

**Line 71**: Type mismatch in setObservations

#### src/ui/viewer/hooks/useStats.ts (1 error)
**Line 13**: Argument of type 'unknown' not assignable to SetStateAction

**Fix**: Add DOM lib to tsconfig for viewer files or add type assertions

**Line 5**: Cannot find name 'document'
**Multiple**: JSX errors (expected, built with esbuild)

#### src/ui/viewer/App.tsx (3 errors)
**Lines 63, 66, 69**: Type mismatch errors in setState callbacks

## Priority Fix Order

1. **High Priority - Breaks build:**
   - src/shared/config.ts (__DEFAULT_PACKAGE_VERSION__)
   - src/hooks/index.ts (module import errors)
   - src/sdk/index.ts (buildFinalizePrompt export)
   - src/shared/storage.ts (legacy interface usage)

2. **Medium Priority - Type safety:**
   - src/sdk/parser.ts (null handling)
   - src/services/sync/ChromaSync.ts (logger Component type)
   - src/servers/search-server.ts (unknown types)
   - React hooks (unknown types)

3. **Low Priority - Cosmetic:**
   - Unused variable warnings
   - JSX errors (these are expected, esbuild handles them)
   - DOM type errors in viewer (handled by esbuild)

4. **Legacy/Cleanup:**
   - src/services/sqlite/Database.ts (remove bun:sqlite)
   - src/services/sqlite/migrations.ts (update to better-sqlite3)
   - src/shared/storage.ts (remove entire file if legacy)
