+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# QVAC CLI
+
+A command-line interface for the QVAC ecosystem. QVAC CLI provides tooling for building, bundling, and managing QVAC-powered applications.

+- [Installation](#installation)
+- [Command Reference](#command-reference)
+  - [`bundle sdk`](#bundle-sdk)
+- [Configuration](#configuration)
+- [Development](#development)
+- [License](#license)
+
+## Installation
+
+Install globally:
+
+```bash
+npm i -g qvac
+```
+
+Or use directly via npx:
+
+```bash
+npx qvac <command>
+```
+
+## Command Reference
+
+### `bundle sdk`
+
+Generate a tree-shaken Bare worker bundle containing the plugins you select (defaults to all built-in plugins).
+
+```bash
+qvac bundle sdk [options]
+```
+
+**What it does:**
+
+1. Reads `qvac.config.*` from your project root (if present)
+2. Resolves enabled plugins from the `plugins` array (defaults to all built-in plugins if omitted)
+3. Generates worker entry files with **static imports only**
+4. Bundles with `bare-pack --linked`
+5. Generates `addons.manifest.json` from the bundle graph
+
+**Options:**
+
+| Flag | Description |
+|------|-------------|
+| `--config, -c <path>` | Config file path (default: auto-detect `qvac.config.*`) |
+| `--host <target>` | Target host (repeatable, default: all platforms) |
+| `--defer <module>` | Defer a module (repeatable, for mobile targets) |
+| `--quiet, -q` | Minimal output |
+| `--verbose, -v` | Detailed output |
+
+**Examples:**
+
+```bash
+# Bundle with default settings (all platforms)
+qvac bundle sdk
+
+# Bundle for specific platforms only
+qvac bundle sdk --host darwin-arm64 --host linux-x64
+
+# Use a custom config file
+qvac bundle sdk --config ./my-config.json
+
+# Verbose output for debugging
+qvac bundle sdk --verbose
+```
+
+**Output:**
+
+| File | Description |
+|------|-------------|
+| `qvac/worker.entry.mjs` | Standalone/Electron worker with RPC + lifecycle |
+| `qvac/worker.pear.entry.mjs` | Pear desktop apps (registers plugins → loads app worker) |
+| `qvac/worker.bundle.js` | Final bundle for mobile/Pear runtimes |
+| `qvac/addons.manifest.json` | Native addon allowlist for tree-shaking |
+
+> **Note:** Your project must have `@qvac/sdk` and `bare-pack` installed. Install `bare-pack` as a devDependency: `npm i -D bare-pack` or `bun add -d bare-pack`
+
+## Configuration
+
+The CLI reads configuration from `qvac.config.{json,js,mjs,ts}` in your project root.
+
+If no config file is found, the CLI bundles all built-in plugins.
+
+> **Note:** `qvac.config.ts` is supported via `tsx` internally (no user setup required).
+
+This file is primarily the SDK runtime config, but `qvac bundle sdk` also reads these **bundler-only** keys (ignored by the SDK at runtime):
+
+| Key | Type | Required | Description |
+|-----|------|----------|-------------|
+| `plugins` | `string[]` | No | Module specifiers, each ending with `/plugin` (defaults to all built-in plugins) |
+| `pearWorker` | `string` | No | Path to your app worker module (default: `worker.js`) |
+
+> **Custom plugin contract:** custom `*/plugin` modules must **default-export** the plugin object.
+
+**Built-in plugins:**
+
+```
+@qvac/sdk/llamacpp-completion/plugin
+@qvac/sdk/llamacpp-embedding/plugin
+@qvac/sdk/whispercpp-transcription/plugin
+@qvac/sdk/nmtcpp-translation/plugin
+@qvac/sdk/onnx-tts/plugin
+@qvac/sdk/onnx-ocr/plugin
+```
+
+**Example configurations:**
+
+```json
+// qvac.config.json - LLM only
+{
+  "plugins": [
+    "@qvac/sdk/llamacpp-completion/plugin"
+  ]
+}
+```
+
+```json
+// qvac.config.json - Multiple plugins + custom Pear worker
+{
+  "plugins": [
+    "@qvac/sdk/llamacpp-completion/plugin",
