<p>Package manifests declare every framework capability they register:</p>
<pre data-language="json"><code>&#123;
&quot;wrnexus&quot;: &#123;
&quot;permissions&quot;: [&quot;routes&quot;, &quot;migrations&quot;],
&quot;routes&quot;: [&#123; &quot;kind&quot;: &quot;api&quot;, &quot;path&quot;: &quot;/api/example&quot;, &quot;entry&quot;: &quot;./route.ts&quot; &#125;]
&#125;
&#125;</code></pre>
<p>Applications can enable fail-closed grants:</p>
<pre data-language="ts"><code>export default &#123;
pluginPermissions: &#123;
enforce: true,
grants: &#123; &quot;example-plugin&quot;: [&quot;routes&quot;] &#125;,
&#125;,
&#125;;</code></pre>
<p>Discovery rejects used-but-undeclared capabilities with <code>WRN-PLUGIN-PERMISSION-UNDECLARED</code> and ungranted capabilities with <code>WRN-PLUGIN-PERMISSION-DENIED</code>. Permissions cover components, browser runtime, assets, styles, routes, middleware, migrations, config, transforms, diagnostics/tooling, and server/build hooks.</p>
<h3 id="compatibility-matrices">Compatibility matrices</h3>
<p>Manifests can add <code>compatibility: &#123; bunMin: &quot;1.3.0&quot;, os: [&quot;linux&quot;, &quot;darwin&quot;] &#125;</code> alongside <code>runtimes</code> and <code>requires</code>. Use <code>testPluginCompatibility(manifest, targets)</code> in a package test to exercise the complete support matrix. Runtime discovery enforces the same Bun minimum, OS, runtime, and capability declarations used by the test kit.</p>
<p>Deterministic WRNexusJS plugin contracts for configuration, AST/code transforms, diagnostics, development servers, production builds, and DevToolbar extensions.</p>
<p>Use <code>definePlugin()</code> and declare <code>enforce</code>, <code>before</code>, or <code>after</code> when ordering matters. Duplicate names and dependency cycles are rejected.</p>
<h3 id="complete-lifecycle-and-contributions">Complete lifecycle and contributions</h3>
<p>Plugins may implement <code>setup</code>, <code>configure</code>, <code>configResolved</code>, <code>transformAst</code>, <code>transformCode</code>, <code>diagnostics</code>, <code>routes</code>, <code>configureServer</code>, <code>buildStart</code>, <code>buildEnd</code>, <code>render</code>, <code>deploy</code>, <code>shutdown</code>, and <code>hmrUpdate</code>. The runner preserves resolved plugin order for every hook and executes <code>setup</code> exactly once.</p>
<p>In addition to components, routes, middleware, assets, styles, runtimes, and migrations, plugins can contribute <code>directives</code>, <code>cliCommands</code>, <code>virtualModules</code>, <code>deploymentAdapters</code>, <code>configSchemas</code>, <code>documentation</code>, and <code>typeDefinitions</code>. Names are collision checked. Configuration schemas run after configuration resolution, CLI commands are callable as normal <code>wrnexus</code> commands, directives participate in AST transformation, and production builds materialize virtual modules and invoke matching contributed adapters.</p></section><section id="api" class="api"><h2>Complete TypeScript API</h2><p>Generated from the exact installed package declarations.</p><pre data-language="typescript"><code>export &#123; PageAst, WrnDiagnostic &#125; from '@wrnexus/syntax';
