+ <h2>Architecture</h2>
+ <p>newOS4 v4.2 uses a <strong>modular class-based architecture</strong> with async dependency loading:</p>
+ <ul>
+ <li><strong>module-loader.js</strong> โ€” 4-phase async loader: VFS โ†’ ModuleManager โ†’ OllamaManager/Terminal โ†’ Ext modules. Cache-busting via localStorage version key + per-load timestamps.</li>
+ <li><strong>VirtualFileSystem</strong> โ€” localStorage-backed in-browser filesystem with VFS checkpoints (snapshot/rollback), trash system (rm โ†’ trash, ls-trash, empty-trash), and dirty-flag auto-save.</li>
+ <li><strong>ModuleManager</strong> โ€” Central registry with load/unload/reload, ASI-safe comment-stripped class parsing, <code>loadModuleFromCode()</code> for runtime module loading.</li>
+ <li><strong>OllamaManager โ†’ LLMRouter</strong> โ€” Multi-provider router with auto-fallback chain. Supports Ollama (native) + any OpenAI-compatible API (OpenRouter). SSE streaming parsing. Provider priority-based failover.</li>
+ <li><strong>SecretVault</strong> โ€” AES-256-GCM encrypted credential manager via Web Crypto API. PBKDF2 key derivation (100K iterations). PIN or open mode.</li>
+ <li><strong>Terminal</strong> โ€” Full terminal with autocomplete, command history, pipe support, clickable output, dirty-flag auto-save, output trimming (200-line cap with memory-pressure auto-reduction).</li>
+ </ul>
+
+ <h3>Module System</h3>
+ <p><strong>25 core modules</strong> (foundation + built-in) + <strong>16 ext modules</strong> = 41 total. All ES6 classes registered via <code>webx11.moduleManager.registerModule()</code>. Ext modules are togglable via the startup gear on splash. Modules report requirements via <code>requirements()</code> method โ€” checked by the <code>check</code> command.</p>
+ <p><strong>Dynamic help system:</strong> Every module implements <code>getHelpInfo()</code> returning a command โ†’ description map. <code>ModuleManager.getAllHelp()</code> collects all entries at runtime. No more hardcoded 195-line help map. New modules appear in <code>help</code> immediately.</p>
+</section>
+
+<section>

+ <h2>Recent Improvements</h2>
+
+ <h3>๐Ÿ” SecretVault (2026-05-25)</h3>
+ <p>AES-256-GCM encrypted credential manager using Web Crypto API. PBKDF2 key derivation (100K iterations) with salt. PIN mode or open mode. 7 CLI commands. Auto-redacts stored secrets from output. Integrated with LLMRouter for API key storage.</p>
+
+ <h3>๐Ÿ”„ LLMRouter (2026-05-25)</h3>
+ <p>Refactored from single-endpoint OllamaManager into a multi-provider router with priority-based fallback. Supports Ollama and any OpenAI-compatible API (OpenRouter, etc.). SSE streaming parsing. Provider auto-fallback on failure with per-provider stats tracking.</p>
+
+ <h3>๐Ÿ“ฆ Context Compression (2026-05-25)</h3>
+ <p>When AI conversation exceeds 2000 tokens, <code>_compressContext()</code> keeps last 3 exchanges, summarizes the rest into one system message via AI summarization or fallback truncation. Also available as <code>ai-compress</code> command. Max tool turns increased from 5 to 8.</p>
+
+ <h3>๐Ÿ“ธ VFS Checkpoints + Trash (2026-05-25)</h3>
+ <p>Snapshot/rollback system (<code>checkpoint</code>, <code>rollback</code>, <code>checkpoint-list</code>, <code>checkpoint-del</code>) plus trash system (<code>rm</code> โ†’ trash, <code>trash-dir</code>, <code>ls-trash</code>, <code>empty-trash</code>). Auto-prunes to max 10 checkpoints.</p>
+
+ <h3>๐Ÿงฐ Tool Registry + File Manager (2026-05-25)</h3>
+ <p>Tool Registry: every module implements <code>requirements()</code>. File Manager: 704-line fullscreen overlay with sidebar, preview pane, search, edit, download, delete commands.</p>
+
+ <h3>๐Ÿงฐ Dynamic Help System & Module Loading Fixes (2026-05-25)</h3>

Fixed double-loading of ext modules (skip list + relative URL guard in <code>registerModule()</code>). Fixed ASI comment-stripping bug in class parsing. Added <code>loadModuleFromCode()</code> for runtime module loading. Fixed <code>check_updates</code> returning empty.</p>
+
+ <h3>๐Ÿง  AI Session Terminal Tool + Error Tracking (2026-05-25)</h3>
+ <p>Added <code>session_terminal</code> tool: reads last 50 lines of terminal auto-save for context when user references past terminal work. Added <code>_trackToolFailure()</code>: after 3 failures on the same tool, warns user and suggests creating a workaround skill. Per-tool timing logs with duration.</p>
+
+ <h3>๐Ÿ“ WebDAV Browser UI + File Manager (2026-05-25)</h3>
+ <p>Full modal file explorer for the dedicated WebDAV space, with clickable directory navigation, breadcrumbs, file preview (HTML in iframe, text inline), upload button, download on double-click, and refresh. New File Manager ext module adds <code>files</code> and <code>preview</code> commands with fullscreen overlay.</p>
+
+ <h3>๐Ÿ“ฆ 4 New Ext Modules (2026-05-25)</h3>

+
+<section>
+ <h2>Verdict</h2>
+ <p>newOS4 v4.2 is the most <strong>feature-rich</strong> version of the WebX11 Terminal. The refactored modular architecture (41 modules with dynamic help, SecretVault, LLMRouter, context compression, VFS checkpoints, trash system, tool registry, and file manager) makes it uniquely capable โ€” while keeping the main.html at just 36KB.</p>
+ <p>The dedicated instance at <code>/spaces/newos4/</code> with nginx autoindex, WebDAV token authentication, and a proper API backend gives it real cloud-backed persistence. Session nesting is fixed, auto-save only fires on actual changes, the <code>mem</code> command gives live heap visibility, and output trimming prevents browser crashes under memory pressure.</p>
+ <p><strong>Best for:</strong> Power users, developers, and anyone who wants a browser-based terminal with AI that can learn, grow, and securely store credentials.</p>
+ <p><strong>Not for:</strong> Users who just want quick AI chat, or users without Ollama/OpenRouter access.</p>
+ <p>Rating: <strong>๐Ÿงฉ๐Ÿงฉ๐Ÿงฉ๐Ÿงฉ๐Ÿงฉ</strong> (5/5 โ€” most advanced WebX11 Terminal variant)</p>
