+      <ul>
+        <li><strong>AI assistant POST support</strong> — <code>web_fetch</code> tool now accepts <code>method=POST</code>, <code>body</code>, and <code>content_type</code> params. AI can now fetch POST-only APIs (Hyperliquid, financial APIs) without telling the user to "use curl". POST routes through <code>/api/fetch</code>; GET still uses <code>/api/extract</code> for cleaner output.</li>
+        <li><strong>AI assistant error parsing</strong> — <code>web_search</code> and <code>web_fetch</code> now parse JSON errors from proxy and surface the real reason (was just "HTTP 500" with no details).</li>
+        <li><strong>30s frontend timeout</strong> — <code>fetch</code>, <code>extract</code>, and <code>search</code> now abort after 30s with a helpful message. Replaces 15s silent freeze. Implementation: <code>AbortController</code>.</li>
+        <li><strong>Loading indicator for <code>--summarize</code></strong> — Shows "⏳ AI overview will be generated (1-3s)..." before the LLM call, so user knows the terminal is alive.</li>
+        <li><strong>Extract follow-up hint</strong> — After <code>extract</code>, shows: "💡 Try <code>summarize &lt;url&gt;</code> for AI summary, or <code>nvfs-resolve &lt;concept&gt;</code> to find related files".</li>
+        <li><strong>Backend script/style strip</strong> — Extract's regex fallback now strips <code>&lt;script&gt;</code>, <code>&lt;style&gt;</code>, <code>&lt;noscript&gt;</code> and HTML comments. Prevents raw JS leaking into extracted text on BS4 failures.</li>
+        <li><strong><code>web</code> alias removed</strong> — Was a duplicate of <code>fetch</code> that didn't appear in autocomplete. Confusing. Just use <code>fetch</code>.</li>
+        <li>Cache: <code>2026-06-10-v4.5.40</code> — hard refresh required</li>
+      </ul>
+    </div>

+      <div class="v-header"><span class="v-num">v4.5.39 — June 2026</span><span class="v-date">2026-06-10</span></div>
+      <ul>
+        <li><strong>POST support in <code>/api/fetch</code></strong> — Proxy was GET-only, blocking any API that requires POST (Hyperliquid <code>/info</code>, etc). Now accepts <code>method=POST&amp;body=...&amp;content_type=...</code> query params with 10KB body cap and method-aware cache key.</li>
+        <li><strong><code>fetch</code> command gains 3 flags</strong> — <code>--post=BODY</code> sends a POST request with the given body, <code>--type=CT</code> sets the Content-Type header (defaults to <code>application/json</code> if <code>--post</code> is set), <code>--raw</code> shows untruncated response. Example: <code>fetch https://api.hyperliquid.xyz/info --post='{"type":"l2Book","coin":"HYPE"}' --type=application/json</code></li>
+        <li><strong>Better error messages</strong> — Frontend <code>fetch</code> now parses JSON error from proxy and shows the real reason (was just "HTTP 502" with no details).</li>
+        <li>Cache: <code>2026-06-10-v4.5.39</code> — hard refresh required</li>
+      </ul>

+      <ul>
+        <li><strong>Keyboard shortcuts</strong> — <code>Ctrl+L</code> clears the output area, <code>Ctrl+C</code> cancels the current input line (prints <code>^C</code>), <code>Ctrl+U</code> clears the input field. Standard terminal conventions now work.</li>
+        <li><strong>Shift+Tab cycles backward</strong> — autocomplete suggestions can be cycled in both directions.</li>
+        <li><strong>Send button → 48px tappable</strong> — was 31px (fails mobile/tablet tap target). Now <code>min-width: 48px; min-height: 48px</code> per Android/iOS standards.</li>
+        <li><strong>Autocomplete argType fixes</strong> — <code>nvfs-config</code>, <code>nvfs-alias</code>, <code>skill-list</code> now show enum values (config keys, alias actions, skill categories) instead of file paths. <code>nvfs-sync</code>/<code>nvfs-save</code>/<code>nvfs-cancel</code>/<code>nvfs-status</code> marked as <code>argType: 'none'</code> so they don't show file suggestions.</li>
+        <li><strong>Stale autocomplete cleared</strong> — Tab suggestions from prior input no longer linger when you start typing something new.</li>
+        <li><strong>History cap on startup</strong> — <code>terminal-cmd-history</code> config now applies on page load, not "next save" (which never happened).</li>
+        <li>Cache: <code>2026-06-10-v4.5.38</code> — hard refresh required</li>

+      <ul>
+        <li><strong>/skills/index.json re-index loop FIXED</strong> — <code>skill-pack-core.seed()</code> was rewriting the <code>updated</code> timestamp for all 8 core skills on every page refresh, causing NVFS to see a hash mismatch and re-queue the 7KB JSON for LLM extraction every run. Now <code>seed()</code> compares existing file content to bundled content and only writes the index if something actually changed. Eliminates the 5-concepts-from-1-file loop on every refresh.</li>
+        <li><strong>One-time data fix</strong> — After deploying, the existing stale <code>updated</code> timestamp in your VFS will be re-evaluated on next refresh. If it matches the bundled timestamp, the loop stops immediately. If not, one final write happens and the loop is dead thereafter.</li>

+      <ul>
+        <li><strong>Deep pass output shows file paths</strong> — Was "5 LLM concepts across 1 file" (no path). Now lists up to 20 files with their concept counts. Makes it obvious if a single file keeps re-processing every refresh (loop detection).</li>
+        <li><strong>Auto-sync output shows file paths</strong> — Same treatment: "re-indexed N file(s)" now lists the actual paths so you can see what's looping.</li>
+        <li><strong>nvfs-status shows LLM/fast breakdown</strong> — Two new lines: "Fast concepts: N" and "LLM concepts: N (across M files)". Proves persistence is working without needing DevTools inspection.</li>
+        <li><strong>Deep pass message clearer</strong> — "added N new LLM concepts (M files). Total in index: X" — distinguishes the per-pass delta from the persisted total.</li>

+      <div class="v-header"><span class="v-num">v4.5.35 — June 2026</span><span class="v-date">2026-06-10</span></div>
+      <ul>
+        <li><strong>NVFS bug fix audit (7 bugs)</strong> — Stale <code>/sys/...</code> entries from pre-v4.5.34 builds cause permanent re-index loops. <code>init()</code> now auto-purges them on first run with a one-time warning.</li>
+        <li><strong>Cancel responsive</strong> — <code>nvfs-cancel</code> now checks between every LLM call (was: between every batch of 3). Stop within one 30s call instead of waiting up to 90s.</li>
+        <li><strong>Save race fixed</strong> — <code>nvfs-save</code> and end of deep pass now await in-flight VFS save instead of clobbering the debounce flag. Prevents silent LLM concept loss on concurrent writes.</li>
+        <li><strong>init() now awaits VFS load</strong> — Was fire-and-forget; first <code>nvfs-status</code> could return empty even when an index existed. <code>module-manager.js</code> already awaits init(), so making it async is safe.</li>
+        <li><strong>Deep-mode warning shown once</strong> — Was spammy on every <code>nvfs-index</code> call. Tracked by session flag <code>_warnedAboutLLMStrip</code>.</li>
+        <li><strong>Tag extraction fixed</strong> — <code>_extractConcepts</code> used <code>tagMatches[0]</code> (whole match) instead of capture group, so inline <code>#tag1 #tag2</code> only captured <code>#tag1</code>. Now correctly splits on commas or captures all hash tags.</li>
+        <li><strong>Filter defensive</strong> — <code>_isSystemFile</code> split into clean two-check structure. <code>node_modules</code> check now uses normalized path so <code>node_modules/foo.js</code> (no leading slash) also gets filtered.</li>
+        <li>Cache: <code>2026-06-10-v4.5.35</code> — hard refresh required</li>

         <li><strong>NVFS deep index persistence</strong> — LLM-generated concepts now survive page refresh. <code>_processDeepQueue()</code> calls <code>_saveIndex()</code>. Deep concepts written to disk on completion.</li>
