-### Package.json Auto-Update
+### Package.json Exports Management
 
-The build script automatically updates `package.json`:
+The `exports` field in `package.json` has two categories: **manual** and **automated**.
 
-1. Removes old `./test/*` exports
-2. Adds new exports from test package
-3. Ensures `dist/test` is in the `files` array
+#### Manual exports
 
-Core package exports (`./client`, `./module-runner`, `./internal`, `./dist/client/*`, `./types/*`) are defined statically in `package.json` and not auto-generated, since they match upstream Vite's exports structure.
+All non-`./test*` exports are manually maintained in `package.json`. These fall into two groups:
 
-This keeps the CLI package exports in sync with both upstream Vite and the test package without manual maintenance.
+**CLI-native exports** — point to CLI's own compiled TypeScript (built by `buildCli()` via tsc):
+
+| Export           | Description                |
+| ---------------- | -------------------------- |
+| `.`              | Main entry (CLI utilities) |
+| `./bin`          | CLI binary entry point     |
+| `./binding`      | NAPI native binding        |
+| `./lint`         | Lint utilities             |
+| `./pack`         | Pack utilities             |
+| `./package.json` | Package metadata           |
+
+**Core shim exports** — point to shim files auto-generated by `syncCorePackageExports()` that re-export from `@voidzero-dev/vite-plus-core`. The shim files are regenerated on each build, but the `package.json` entries themselves are manual:
+
+| Export               | Description                                                             |
+| -------------------- | ----------------------------------------------------------------------- |
+| `./client`           | Triple-slash reference for ambient type declarations (CSS modules, etc) |
+| `./module-runner`    | Vite module runner for SSR/environments                                 |
+| `./internal`         | Internal Vite APIs                                                      |
+| `./dist/client/*`    | Client runtime files                                                    |
+| `./types/internal/*` | Blocked (`null`) to prevent access to internal types                    |
+| `./types/*`          | Type-only re-exports                                                    |
+
+**Note**: The core package's own exports (which the shims point to) are generated upstream by `packages/tools/src/sync-remote-deps.ts`. See [Core Package Bundling](../core/BUNDLING.md) for details.
+
+#### Automated exports (`./test/*`)
+
+All `./test*` exports are fully managed by `syncTestPackageExports()`. The build script:
+
+1. Reads `packages/test/package.json` exports
+2. Creates shim files in `dist/test/`
+3. Removes old `./test*` exports from `package.json`
+4. Merges in newly generated test exports
+5. Ensures `dist/test` is in the `files` array
