+- **Unused index entrypoint**: Removed `src/index.ts` and package exports for `"."` and `"./index"`
+  - This was a leftover from socket-registry and not needed for this library
+  - Users should import specific modules directly (e.g., `@socketsecurity/lib/logger`)
+  - Breaking: `import { getDefaultLogger } from '@socketsecurity/lib'` no longer works
+  - Use: `import { getDefaultLogger } from '@socketsecurity/lib/logger'` instead
