    <p>Not file conversion — health checks and WOPI helpers against CODE.</p>

    <table style="width:100%; font-size:12px;">
        <tr><th>Operation</th><th>You get</th></tr>
        <tr><td><code>capabilities</code></td><td>JSON: what CODE supports (convert-to, etc.)</td></tr>
        <tr><td><code>discovery</code></td><td>XML: mime → editor URL</td></tr>
        <tr><td><code>buildEditor</code></td><td><code>msg.editorUrl</code> from <code>msg.wopiSrc</code> + <code>msg.token</code></td></tr>
        <tr><td><code>checkFileInfo</code></td><td>JSON about the file (WOPI host, usually Nextcloud)</td></tr>
        <tr><td><code>getFile</code></td><td>file bytes via WOPI GET</td></tr>
    </table>

    <p><code>buildEditor</code> builds roughly:<br>
    <code>{collaboraPublicUrl}/browser/dist/cool.html?WOPISrc=...&amp;access_token=...</code><br>
    Public URL = Nextcloud/proxy, not internal CODE IP.</p>

    <h4>When to use</h4>
    <ul>
        <li>First test that CODE is up → <code>capabilities</code></li>
        <li>WOPI token from <code>nc-office document:direct</code> → build iframe URL</li>
        <li>Debugging. Save files via WebDAV, not WOPI PutFile.</li>
    </ul>

    <pre>inject → collabora-wopi (capabilities) → debug</pre>
