<h2 id="overview">1. System Overview</h2>
<p>newOS4 is a modular agent operating system with a VFS, pluggable modules, and an AI-driven terminal. v4.5.96 is the latest shipping release after 2 bug-fix sessions.</p>
<ul>
<li><strong>Modules:</strong> 45 (12 core, 33 ext)</li>
<li><strong>Skills:</strong> 40</li>
<li><strong>System agents:</strong> 3 (immutable)</li>
<li><strong>Health:</strong> ✅ OK</li>
</ul>
<h2 id="architecture">2. Architecture</h2>
<h3>Layer 0 — Kernel</h3>
<ul><li>VFS, Module loader, Event bus, Permissions</li></ul>
<h3>Layer 1 — Core AI</h3>
<ul><li>AIModule, ContextModule, AgentLoop, MemoryGraph, WorldModel</li></ul>
<h3>Layer 2 — Domain</h3>
<ul><li>Terminal, ShellModule, Orchestrator, Hyperliquid/VaultMind, FS, Cron, etc.</li></ul>
<h3>Layer 3 — UI / Ext</h3>
<ul><li>Browser, Mindmap, WPM, Sandbox, Floating, WebDAV</li></ul>
<h2 id="shell">3. ShellModule <span class="pill pill-shipped">NEW v4.5.96</span></h2>
<p>Layer-2 module exposing built-in shell commands to the terminal.</p>
<h4>Commands</h4>
<ul>
<li><code>cd</code>, <code>pwd</code>, <code>ls</code>, <code>cat</code>, <code>echo</code>, <code>mkdir</code>, <code>rm</code></li>
<li><code>env</code>, <code>export</code>, <code>unset</code></li>
<li><code>grep</code>, <code>wc</code>, <code>head</code>, <code>tail</code></li>
</ul>
<h4>Pipes & Redirects</h4>
<ul>
<li><code>cmd1 | cmd2</code> — pipe output</li>
<li><code>cmd > file</code> — overwrite</li>
<li><code>cmd >> file</code> — append</li>
</ul>
<h4>Security Gate (v4.5.96)</h4>
<blockquote>Destructive commands (<code>rm</code>, redirects) MUST pass <code>canExecute()</code> gate. Patches assert enforcement at boot, not just API definition.</blockquote>
<h2 id="orchestrator">4. OrchestratorModule <span class="pill pill-fixed">8 fixes v4.5.96</span></h2>
<p>Manages agent lifecycle, task delegation, and worker spawn.</p>
<h4>v4.5.96 Fixes</h4>
<ul>
<li>✅ <strong>F1</strong> <code>spawnAgent()</code> leak — process handle now tracked + cleaned</li>
<li>✅ <strong>F2</strong> <code>delegate()</code> retry loop infinite</li>
<li>✅ <strong>F3</strong> Worker death not detected</li>
<li>✅ <strong>F4</strong> Task queue priority inversion</li>
<li>✅ <strong>F5</strong> State corruption on concurrent register</li>
<li>✅ <strong>F6</strong> Lease acquire race</li>
<li>✅ <strong>F7</strong> Stale agent metadata cache</li>
<li>✅ <strong>F8</strong> <code>killAgent()</code> bypassed on system agents</li>
</ul>
<h2 id="rules">5. Cross-Cutting Rules (R1–R7)</h2>
<p>Extracted from v4.5.96 bug fixes. All module authors MUST follow.</p>
<h3>R1 — Lifecycle: registerModule() calls init()</h3>
<p>All timers, intervals, and event listeners MUST be registered in <code>init()</code> and stored for cleanup. No orphan timers.</p>
<h3>R2 — Error visibility</h3>
<p><code>this.print</code> writes to AI context. <code>this.terminal.print</code> writes to user only. Use AI-visible for errors that affect reasoning.</p>
<h3>R3 — Cleanup via try/finally</h3>
<p>All monkey-patches, depth counters, and global state mutations MUST use <code>try/finally</code> to guarantee rollback.</p>
<h3>R4 — Security patches ASSERT enforcement</h3>
<blockquote>A security patch that defines an API but doesn't assert it's enforced is a vulnerability. Boot-time self-test required.</blockquote>
<h3>R5 — System agents are immutable</h3>
<p>The 3 system agents (coder, researcher, reviewer) cannot be killed, purged, or modified. <code>killAgent()</code> checks <code>isSystemAgent</code> flag.</p>
<h3>R6 — Compute state at use site</h3>
<p>Don't cache module state at boot. Compute on demand. Stale-cache bugs were 30% of v4.5.96 fixes.</p>
<h3>R7 — Parser dedup: extract once</h3>
<p>Helpers like <code>extractRedirect()</code> must be called exactly once per command parse. Double-extraction is a P0-class bug.</p>
