+<p class="lead">What an "awesome texting experience" feels like from the user's side, and the abstract architecture that must be behind it. Implementation choices (tmux vs <code>claude -c -p</code>, one-box vs two-box) are deferred to the concrete-option mockups — this page is <em>what it must feel like</em>, not <em>how we build it</em>.</p>
+
+<div class="quote-box">
+ <div class="label">The one test</div>
+ <p>A friend adds the bot to a group text. Over the next hour: it stays quiet during chatter. When @mentioned with a public-friendly question, it replies usefully in <15 s. When someone asks "is Jacob free Tuesday?", the bot says "let me check", DMs Jacob privately with the question + proposed response, and only answers the group once Jacob approves. No one sees private information Jacob didn't explicitly approve.</p>

+ <li>Nothing says <em>one process or two</em>, <em>one box or many</em>, <em>tmux or not</em>.</li>
+ <li>Knowledge layer is drawn as one role but in reality is <code>{ per-chat manifest store, noos graph, transcript, files }</code> — any of which can live anywhere.</li>
+ <li>The Channel adapter hides Linq vs OpenChat specifics — both normalize to the same event vocabulary.</li>
+ <li>The Executor is the most replaceable piece: <code>claude -c -p</code> per turn, a tmux REPL, OpenClaw, or something else — all satisfy this diagram.</li>
