  <div class="grp">How a web page drives Adom Bridge (the embed pattern + sample code)</div>
  <div class="doc">
    <p>There is <b>no SDK and no library</b>. A web page drives the machine with a plain <code>fetch()</code> (AJAX) to Adom Bridge's loopback HTTP API at <code>http://127.0.0.1:24680</code>. That is the whole integration: the wiki, or any other Adom surface, embeds a page whose buttons do the fetches below. Every state-changing call pops an Allow / Deny prompt in the app before anything runs.</p>

    <h3>1. Detect it (open to any page, no prompt)</h3>
    <pre><code>const r = await fetch("http://127.0.0.1:24680/health");
const h = await r.json();              // { ok: true, service: "adom-bridge" }
const running = h.service === "adom-bridge";</code></pre>

    <h3>2. Run one verb (pops Allow / Deny in the app, then runs)</h3>
    <pre><code>const r = await fetch("http://127.0.0.1:24680/command", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ command: "notify_user", args: { title: "Hi", body: "from a web page" } })
});
const out = await r.json();
// 200 = ran. 403 { errorCode: "web_denied" } = the user clicked Deny.
// A screenshot comes back as base64 you render inline:
//   { command: "desktop_screenshot_base64", args: { hwnd: 12345, maxWidth: 900 } }  ->  out.image</code></pre>

    <h3>3. Stream a long op (open app &rarr; wait for its window &rarr; screenshot), live status over ONE connection</h3>
    <pre><code>const resp = await fetch("http://127.0.0.1:24680/command/stream", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ label: "Open KiCad", steps: [
    { command: "kicad_open_symbol_editor", args: {}, label: "Launching KiCad", usuallySec: 30 },
    { waitForWindow: { titleContains: "Symbol Editor", timeoutSec: 90 }, label: "Waiting for the window" }
  ]})
});
// Read the Server-Sent-Events stream:
const reader = resp.body.getReader(), dec = new TextDecoder(); let buf = "";
for (;;) {
  const { value, done } = await reader.read(); if (done) break;
  buf += dec.decode(value, { stream: true }); let i;
  while ((i = buf.indexOf("\n\n")) >= 0) {
    const block = buf.slice(0, i); buf = buf.slice(i + 2);
    let ev = "message", data = "";
    block.split("\n").forEach(l => {
      if (l.startsWith("event:")) ev = l.slice(6).trim();
      else if (l.startsWith("data:")) data += l.slice(5).trim();
    });
    console.log(ev, JSON.parse(data));   // ev = start | progress | image | done
  }
}</code></pre>

    <h3>To capture an app's FULL state, screenshot every one of its windows</h3>
    <pre><code>// 1) list windows, 2) keep the app's, 3) screenshot EACH by hwnd (the parent/child array).
const wins = JSON.parse((await (await fetch(API + "/command", { method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ command: "desktop_list_windows" }) })).json()).output).data.windows;
const mine = wins.filter(w => /kicad|symbol editor|pcb editor/i.test(w.title));
for (const w of mine) {
  const shot = await (await fetch(API + "/command", { method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ command: "desktop_screenshot_base64", args: { hwnd: w.hwnd, maxWidth: 900 } }) })).json();
  render(shot.image, w.title);   // shot.image is base64 PNG
}</code></pre>

    <h3>Security and embedding notes</h3>
    <ul>
      <li>Adom Bridge binds <b>127.0.0.1 only</b> and runs the human Allow / Deny gate on every command. Detection (<code>/health</code>, <code>/status</code>) is open; commands are gated. It also supports an optional cloud-K-V handshake so only the real signed-in wiki can even reach the prompt.</li>
      <li><code>http://127.0.0.1</code> is a browser <b>secure context</b>, so an HTTPS page reaching it is <b>not</b> blocked as mixed content, and Adom Bridge returns the CORS + Private-Network-Access headers a public page needs.</li>
      <li><span class="warn">Caveat - the wiki readme iframe cannot do this yet.</span> The wiki serves a readme.html inside a sandboxed, null-origin iframe with <code>Content-Security-Policy: ... connect-src 'self'</code>, which blocks the fetch to loopback. A normally-served page (like this one) works fine; the wiki-embedded case needs the wiki to allow <code>connect-src http://127.0.0.1:*</code> (filed as a wiki issue). Until then, embed this on a normally-served Adom page, not inside the sandboxed readme iframe.</li>

  // ==========================================================================
  // REFERENCE IMPLEMENTATION - rendering a bridge's measured progress on a web
  // page. THIS is the part to copy onto wiki.adom.inc.
  // --------------------------------------------------------------------------
  // Everything below is bridge-AGNOSTIC. It never mentions kicad or fusion, and
  // it works for a bridge that does not exist yet, because it matches on the
  // SHAPE of the measured-progress contract every bridge emits:
  //
  //   { phase, stepLabel, percent, elapsedSec, estimatedSec, etaSec,
  //     confidence, startKind, blockedBy?, measured? }
  //
  // Two functions, two jobs: readProgressBlock() gets the block out of whatever
  // the bridge answered with, renderProgressBlock() draws it. Keeping them apart
  // is deliberate - the reading half is where the traps are, the drawing half is
  // where the honesty rules are, and you will want to restyle one without
  // touching the other.
  // ==========================================================================

  // ---- 1. READ ------------------------------------------------------------
  // A bridge reports progress at TWO different moments, and a page that reads
  // only the first can show a bar that never moves:
  //
  //   a) TERMINAL FRAME - a top-level `progress` on the slow verb's own
  //      response. Always arrives at percent:100, because by the time the verb
  //      answers, the work is finished. On its own this is a completion
  //      receipt, NOT a progress bar.
  //   b) LIVE POLL - an `active[]` array of those same blocks, one per
  //      in-flight phase, from the bridge's fast progress verb while the slow
  //      work is still running. THIS is the one that animates: poll it about
  //      once a second and you get the stream of rising frames a bar needs.
  //
  // ⚠ THE TRAP: `active` is overloaded in the wild. The canonical contract uses
  // an ARRAY of blocks; some bridges' demo verbs use a BOOLEAN meaning
  // "still running". Disambiguate by TYPE, never by truthiness - `active:false`
  // and `active:[]` both mean idle, but `if (resp.active)` is true for a
  // non-empty array AND for the boolean, and false for BOTH idle forms, so a
  // truthiness test silently conflates a running job with a finished one.
  function readProgressBlock(resp) {
    if (!resp || typeof resp !== "object") return null;

    // Terminal frame wins when present: it is a verb's authoritative last word,
    // and it must not be overridden by a stale in-flight row.
    if (isProgressBlock(resp.progress)) return resp.progress;

    if (Array.isArray(resp.active)) {
      var rows = resp.active.filter(isProgressBlock);
      if (!rows.length) return null;                 // idle - draw nothing
      // Several phases in flight: draw the LEAST COMPLETE one. The honest answer
      // to "how far along is this?" is bounded by the slowest phase; drawing the
      // furthest-along one promises a finish the work has not earned. A row with
      // no percent sorts last so a row that HAS one wins.
      return rows.slice().sort(function (a, b) {
        return pctOf(a) - pctOf(b);
      })[0];
    }
    return null;
  }
  function pctOf(b) {
    return typeof b.percent === "number" ? b.percent : Infinity;

  // contract uses {title, value, status}), so a key name proves nothing.
  // Require a field only the measured-progress contract defines.

    return !!o && typeof o === "object" && !Array.isArray(o) &&
      ("percent" in o || "phase" in o || "etaSec" in o);
  }

  // ---- 2. RENDER ----------------------------------------------------------
  // Three honesty rules are baked in here on purpose. They are what separate a
  // progress bar the user can trust from one that is merely decorative:
  //
  //   1. An ESTIMATE IS MARKED AS ONE. `confidence` is the bridge telling you
  //      how it got the number: "measured" means it timed this phase on THIS
  //      machine, anything else is a default or a small sample. A guess that
  //      renders identically to a measurement teaches the user to distrust
  //      both, so a non-measured bar is drawn dimmed and labelled.
  //   2. `blockedBy` STOPS THE BAR. It means the work is parked on a HUMAN - a
  //      modal dialog, a login, a save prompt. Nothing will move until the user
  //      acts, so the bar goes amber, stops advancing, and says what it wants.
  //      A bar that keeps sliding while nothing can happen is worse than none.
  //   3. NO PERCENT MEANS INDETERMINATE, not zero. A bridge that honestly says
  //      "I am working but cannot estimate" must not render as a bar stuck at
  //      0%, which reads as "broken".
  function renderProgressBlock(card, b) {
    var p = progressBar(card);
    var blocked = typeof b.blockedBy === "string" && b.blockedBy.trim();
    var estimated = b.confidence && b.confidence !== "measured";
    var pct = typeof b.percent === "number"

    // written for a person; `phase` is the machine-readable namespaced id and
    // is only a fallback.

    if (pct !== null) bits.push(Math.round(pct) + "%");
    var label = b.stepLabel || b.phase || "working";

    // elapsed, and show the estimate it is measured against.

  // TWO CONCURRENT REQUESTS. The slow verb's own response cannot animate
  // anything, because it does not arrive until the work is done - by then the
  // only honest number it can carry is 100%. The poll running ALONGSIDE it is
  // what produces the rising frames. Firing the verb and awaiting it before
  // starting the poll is the single most common way to end up with a bar that

  // is MEMOIZED (one staging per page load; every later button reuses it).

  // write_file as base64 inside the /command JSON body, which caps out around
  // 2.5 MB - so the last three deliberately cross that line (see ab#90). Sizes
  // are the real .step bytes, measured off each page's files listing.
  //
  // Every entry was verified to carry ALL FOUR required files
  // (.kicad_sym + .kicad_mod + .step + .lbr). Plenty of jellybeans on the wiki
  // (1N4148, 2N7000, LM1117, TL074) are missing one and would fail halfway
