Prose explains; this section is for the keyboard.</p> <p><strong>Publication snapshot: September 2026.</strong> Browser flags, origin trials, API availability, and experimental configuration change. Flag values and external documentation details below reproduce the tested builds of this edition. Anything the book&rsquo;s own laboratories did not observe is marked as such.</p> <hr> <h2 id="a1-development-setup">A.1 Development setup</h2> <table> <thead> <tr> <th>Surface</th> <th>Setting / location</th> <th>Value / action</th> <th>Purpose</th> <th>Stability</th> </tr> </thead> <tbody> <tr> <td>Chrome flags</td> <td><code>chrome://flags/#optimization-guide-on-device-model</code></td> <td>Enabled (lab profile)</td> <td>On-device model support for local development</td> <td>Experimental, recheck per build</td> </tr> <tr> <td>Chrome flags</td> <td><code>chrome://flags/#prompt-api-for-gemini-nano</code></td> <td>Enabled where applicable</td> <td>Foundation-model API access for local testing</td> <td>Experimental, recheck per build</td> </tr> <tr> <td>WebMCP</td> <td><code>chrome://flags/#enable-webmcp-testing</code></td> <td>Enabled</td> <td>Local WebMCP development without relying on the origin trial</td> <td>Experimental, recheck per build</td> </tr> <tr> <td>Extensions</td> <td><code>chrome://extensions</code></td> <td>Developer mode, load unpacked</td> <td>Load the Browser AI Observatory</td> <td>Durable workflow</td> </tr> <tr> <td>Diagnostics</td> <td><code>chrome://on-device-internals</code></td> <td>Open model status</td> <td>Inspect on-device model state and errors</td> <td>Browser diagnostic surface</td> </tr> <tr> <td>JavaScript</td> <td><code>LanguageModel.availability(options)</code> in DevTools</td> <td>Run with intended options</td> <td>Operational preflight before creation</td> <td>API contract</td> </tr> <tr> <td>Observatory</td> <td>AI Observatory panel, capability inspection</td> <td>Run inspection</td> <td>Capture the full lifecycle instead of guessing</td> <td>Book tooling</td> </tr> </tbody> </table> <p>Flag values follow the laboratory run-book convention of this edition, not a permanent browser contract.</p>
