  <p>
    Consumes HomeBus telemetry for a single <code>SNZB-05P</code> endpoint and projects it to HomeKit services.
  </p>
  <p>
    Output 3 is not a publish stream anymore. It controls a Node-RED <code>mqtt in</code> node with dynamic subscriptions.
  </p>
  <p>
    On start, the node emits:
    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/last</code>,
    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/value</code>, and
    <code>subscribe &lt;site&gt;/home/&lt;location&gt;/+/&lt;accessory&gt;/availability</code>.
  </p>
  <p>
    The node keeps <code>.../last</code> subscribed until the cold-start bootstrap is complete for all required values.
    A value is considered satisfied when it arrived either from <code>last</code> or from live <code>value</code>.
    Only then does the node emit <code>unsubscribe .../last</code>.
  </p>
  <p>
    Supported input topic shape:
    <code>&lt;site&gt;/home/&lt;location&gt;/&lt;capability&gt;/&lt;accessory&gt;/value</code>,
    <code>&lt;site&gt;/home/&lt;location&gt;/&lt;capability&gt;/&lt;accessory&gt;/last</code>, and
    <code>&lt;site&gt;/home/&lt;location&gt;/&lt;capability&gt;/&lt;accessory&gt;/availability</code>.
  </p>
  <p>
    The node accepts scalar <code>value</code> payloads, string/boolean <code>availability</code> payloads,
    and timestamped <code>last</code> envelopes of the form
    <code>{ value, observed_at, quality }</code>. For <code>last</code>, only <code>payload.value</code> is used.
  </p>
  <h3>Capabilities</h3>
  <p>
    Mappings:
    <code>water_leak -&gt; Leak Sensor</code>,
    <code>battery + battery_low -&gt; Battery</code>.
    Optional <code>tamper</code> updates are folded into HomeKit status flags when available.
  </p>
  <p>
    Subscription topics are generated from the configured <code>site</code>, <code>location</code>, and
    <code>accessory</code>. The bus segment remains fixed to <code>home</code>.
  </p>
  <h3>Outputs</h3>
  <ol>
    <li>Leak Sensor: <code>{ LeakDetected, StatusActive, StatusFault, StatusLowBattery, StatusTampered }</code></li>
    <li>Battery Service: <code>{ StatusLowBattery, BatteryLevel, ChargingState }</code></li>
    <li><code>mqtt in</code> dynamic control messages: <code>{ action, topic }</code></li>
  </ol>
  <h3>HomeKit Service Setup</h3>
  <p>
    The linked <code>homekit-service</code> nodes should explicitly materialize the optional characteristics used by this adapter.
    Set the Battery service node <code>characteristicProperties</code> to:
  </p>
  <pre><code>{"BatteryLevel":{},"ChargingState":{}}</code></pre>
  <p>
    Without these optional characteristics, HomeKit may keep default values until a later update or ignore the fields during startup.
  </p>
