+# A2A Protocol Specification v0.1
+
+## Overview
+Agent-to-Agent (A2A) is a decentralized message protocol for agent negotiation within newOS4. Agents discover each other via VFS registrations and communicate through a shared message queue. No central broker.
+
+## Message Format
+All messages are JSON with this envelope:
+
+```json
+{
+  "a2a_version": "0.1",
+  "msg_id": "<uuid>",
+  "type": "request" | "response" | "broadcast" | "lease" | "heartbeat",
+  "from": "<agent_id>",
+  "to": "<agent_id>" | "*",
+  "timestamp": "<ISO 8601>",
+  "ttl_seconds": 30,
+  "contract": {
+    "capabilities": ["list_files", "read_file", "web_search"],
+    "constraints": {
+      "max_tool_turns": 8,
+      "max_duration_seconds": 60
+    }
+  },
+  "payload": { }
+}
+```
+
+## Transport Layer
+Each agent has a VFS mailbox at `/agents/<agent_id>/inbox.json` and publishes to `/agents/<agent_id>/outbox.json`. The orchestrator monitors inboxes via periodic polling (500ms interval).
+
+## Message Types
+- **request**: Point-to-point task delegation. From=orchestrator, To=worker.
+- **response**: Task result. From=worker, To=orchestrator.
+- **broadcast**: Discovery / capability advertisement. To="*".
+- **lease**: Time-bound contract granting a worker exclusive task rights.
+- **heartbeat**: Alive signal. Every 5 seconds. Missing 3 consecutive = presumed dead.
+
+## Lifecycle
+1. Orchestrator broadcasts AGENT_REQUEST
+2. Workers respond with capability claim
+3. Orchestrator issues LEASE with TTL
+4. Worker executes, sends RESPONSE
+5. Orchestrator ACKs, LEASE expires
+6. Worker returns to available pool

-# newOS4 Bug Fix Suggestions
-
-**Generated:** 2026-05-24  
-**Status:** Pending Review  
-**Priority:** High (13 issues across 7 files)
-
----
-

-
-| Category | Issues | Files | Severity |
-|----------|--------|-------|----------|
-| File Structure | 5 | 4 | High |
-| Agent System | 5 | 2 | High |
-| AI Routing | 2 | 1 | Medium |

-| **Total** | **13** | **7** | |
-
----
-
-## 1. File Structure Issues
-
-### 1.1 Splash Fallback Ext List Incomplete
-- **File:** `index.html`
-- **Line:** 770
-- **Issue:** Splash fallback hardcodes 5 ext modules but `modules/ext/` directory has 8 files
-- **Missing:** `mindmap.js`, `webdav.js`, `skill-pack-core.js`
-- **Fix:**
-  ```javascript
-  // Before (5 modules)
-  ['Extensions', ['calc.js','voice.js','cron.js','theme.js','wpm.js'], false]
-  
-  // After (8 modules)
-  ['Extensions', ['calc.js','voice.js','cron.js','theme.js','wpm.js','mindmap.js','webdav.js','skill-pack-core.js'], false]
-  ```
-
----
-
-### 1.2 Preview Iframe Blocks JavaScript
-- **File:** `index.html`
-- **Line:** 684
-- **Issue:** `<iframe sandbox="allow-same-origin">` missing `allow-scripts`
-- **Impact:** HTML previews with JavaScript don't execute
-- **Fix:**
-  ```html
-  <!-- Before -->
-  <iframe sandbox="allow-same-origin"></iframe>
-  
-  <!-- After -->
-  <iframe sandbox="allow-same-origin allow-scripts"></iframe>
-  ```
-
----
-
-### 1.3 Dead Code: EXT_FILES Array
-- **File:** `module-loader.js`
-- **Lines:** 35-37
-- **Issue:** `EXT_FILES` array defined but never referenced (dead code, wrong count)
-- **Impact:** Maintenance confusion, wrong module count (6 vs actual 8)
-- **Fix:** Remove entirely — ext loading uses separate `extKeys` array on line 159
-
----
-
-### 1.4 Packages.json URL Errors
-- **File:** `packages.json`
-- **Lines:** 7-167
-- **Issues:**
-  - All 18 package URLs point to `modules/<name>.js` (wrong path)
-  - Actual files are in `modules/ext/<name>.js`
-  - 12 packages reference files that don't exist anywhere
-- **Impact:** WPM installs fail with 404 errors
-- **Fix Options:**
-  1. **Clean:** Remove 12 phantom packages, fix 6 real URLs to `modules/ext/`
-  2. **Stub:** Create missing files in `modules/ext/`
-- **Recommendation:** Option 1 (clean) — reduces bloat
-
----
-
-### 1.5 Search Uses Intrusive Alert()
-- **File:** `help.html`
-- **Line:** 1149
-- **Issue:** `alert('No results found')` blocks UI
-- **Impact:** Poor UX, modal interruption
-- **Fix:**
-  ```javascript
-  // Before
-  if (!found) alert('No results found for: ' + query);
-  
-  // After
-  if (!found) {
-      const msg = document.getElementById('search-result-msg');
-      if (msg) {
-          msg.textContent = 'No results found for: ' + query;
-          msg.style.display = 'block';
-          setTimeout(() => { msg.style.display = 'none'; }, 3000);
-      }
-  }
-  ```
-
----
-
-## 2. Agent System Issues
-
-### 2.1 Agent Loop Caps at 1 Turn (Not 5)
-- **File:** `module-aiassist.js`
-- **Lines:** 537-547
-- **Issue:** When model returns text + tool_calls, agent executes tools then `return`s (exits loop)
-- **Impact:** Agent stops after 1 tool turn instead of advertised `MAX_TOOL_TURNS = 5`
-- **Root Cause:** Follow-up text-response block returns instead of continuing loop
-- **Fix:**
-  ```javascript
-  // Before (lines 537-548)
-  if (pendingText) {
-      const followUp = await this.terminal.ollamaManager.chatWithTools(messages, []);
-      if (followUp.message && followUp.message.content) {
-          this.terminal.printAIResponse(followUp.message.content);
-          return { finalAnswer: followUp.message.content, toolTurns }; // ← exits loop
-      }
-  }
-  continue;
-  
-  // After
-  if (pendingText) {
-      messages.push({ role: 'assistant', content: pendingText });
-  }
-  continue; // ← loop continues, allows up to 5 turns
-  ```
-
----
-
-### 2.2 edit_module Not Checked as Destructive
-- **File:** `module-aiassist.js`
-- **Line:** 730
-- **Issue:** `isDestructive()` doesn't include `edit_module` but system prompt (line 227) says it's `(DESTRUCTIVE)`
-- **Impact:** AI told to ask permission but code never confirms
-- **Fix:**
-  ```javascript
-  // Before
-  isDestructive(name) {
-      return name === 'write_file' || name === 'delete_file' || 
-             name === 'run_command' || name === 'make_directory';
-  }
-  
-  // After
-  isDestructive(name) {
-      return name === 'write_file' || name === 'delete_file' || 
-             name === 'run_command' || name === 'make_directory' || 
-             name === 'edit_module';
-  }
-  ```
-
----
-
-### 2.3 Empty tools:[] Sent to Ollama
-- **File:** `module-aiassist.js`
-- **Line:** 539
-- **Issue:** `chatWithTools(messages, [])` sends empty tools array
-- **Impact:** Some Ollama models reject `tools: []`, triggers unnecessary fallback request
-- **Fix:** Remove follow-up call; push text as `assistant` message then `continue` loop (see 2.1)
-
----
-
-### 2.4 Default Model Blocks Auto-Selection
-- **File:** `ollama-manager.js`
-- **Lines:** 8, 42-45
-- **Issue:** Default model `'gemma4:31b-cloud'` is truthy, so auto-selection skipped even if model doesn't exist
-- **Impact:** Users get silent model errors until manually selecting
-- **Fix:**
-  ```javascript
-  // Before (lines 42-45)
-  if (!this.currentModel && this.models.length > 0) {
-      this.currentModel = this.models[0].name;
-      // ...
-  }
-  
-  // After
-  if (!this.currentModel || !this.models.some(m => m.name === this.currentModel)) {
-      if (this.models.length > 0) {
-          this.currentModel = this.models[0].name;
-          // ...
-      }
-  }
-  ```
-
----
-
-### 2.5 abort() Misses chat() and chatStream()
-- **File:** `ollama-manager.js`
-- **Lines:** 70, 140, 176-183
-- **Issue:** `_abortController` only set in `chatWithTools()` (line 195), not in `chat()` or `chatStream()`
-- **Impact:** `ai-stop` command only cancels tool-calling requests, not direct chat or streaming
-- **Fix:**
-  ```javascript
-  // Add to chat() method (around line 70)
-  this._abortController = new AbortController();
-  const signal = this._abortController.signal;
-  const response = await fetch(`${this.endpoint}/api/generate`, {
-      // ...
-      signal
-  });
-  this._abortController = null;
-  
-  // Add to chatStream() method (around line 140) - same pattern
-  ```
-
----
-
-## 3. AI Routing Issues
-
-### 3.1 Unknown Commands Not Awaited (executeCommand)
-- **File:** `terminal.js`
-- **Line:** 629
-- **Issue:** `aiMod.chat([rawInput.trim()])` called without `await`
-- **Impact:** Fire-and-forget execution, errors uncaught, no sequencing
-- **Fix:**
-  ```javascript
-  // Before
-  aiMod.chat([rawInput.trim()]);
-  return;
-  
-  // After
-  this.print('→ Routing to AI assistant...', 'info');
-  await aiMod.chat([rawInput.trim()]);
-  return;
-  ```
-
----
-
-### 3.2 Unknown Commands Not Awaited (dispatchCommand)
-- **File:** `terminal.js`
-- **Line:** 691
-- **Issue:** Same as 3.1 but in `dispatchCommand()` (used for pipe chains)
-- **Fix:** Same as 3.1
-
-**Combined Impact:** Unknown commands like `hello` route to AI but without proper error handling or user feedback
-
----
-
-## 4. Cache Invalidation
-
-### 4.1 Cache Version Stale
-- **File:** `module-loader.js`
-- **Line:** 102
-- **Issue:** `CACHE = '?v=17'` serves old cached modules
-- **Impact:** Browser doesn't re-fetch updated module files
-- **Fix:**
-  ```javascript
-  // Before
-  const CACHE = '?v=17';
-  
-  // After
-  const CACHE = '?v=18';
-  ```
-- **Note:** Requires users to hard refresh (Ctrl+F5 / Cmd+Shift+R)
-
----
-
-## Implementation Priority
-
-### High Priority (Critical Bugs)
-1. **2.1** Agent loop caps at 1 turn — breaks multi-step AI tasks
-2. **1.4** Packages.json 404 errors — WPM installs broken
-3. **2.4** Default model blocks auto-selection — invisible failures
-4. **2.5** abort() incomplete — `ai-stop` doesn't work for chat/stream
-
-### Medium Priority (Functional Issues)
-5. **1.1** Splash fallback incomplete — minor UX issue
-6. **2.2** edit_module destructive check — security inconsistency
-7. **3.1 + 3.2** AI routing without await — error handling gaps
-8. **1.2** Preview iframe sandbox — JS previews broken
-
-### Low Priority (Cleanup)
-9. **1.3** Dead EXT_FILES code — maintenance clarity
-10. **1.5** Search alert() → inline — UX polish
-11. **4.1** Cache version — required after applying fixes
-
----
-
-## Tradeoffs & Considerations
-
-### Packages.json Cleanup (1.4)
-- **Option A (Recommended):** Remove 12 phantom packages
-  - ✅ Reduces bloat, cleaner codebase
-  - ❌ Breaks backward compatibility if anyone installed them
-- **Option B:** Create stub files for missing packages
-  - ✅ Preserves compatibility
-  - ❌ Adds dead weight, maintenance burden
-
-### Agent Loop Change (2.1)
-- Removing follow-up call changes message structure slightly
-- Text+tool hybrid responses now push text as `assistant` message, then loop continues
-- This is correct behavior but differs from original design
-
-### AI Routing (3.1 + 3.2)
-- Routing all unknown commands to AI may increase token usage
-- Consider adding `ai-mode` toggle or `--no-ai` flag for opt-out
-
-### Cache Version (4.1)
-- Bumping version requires all users to hard refresh
-- Consider adding release notes or announcement
-
----
-
-## Testing Checklist
-
-After applying fixes:
-
-- [ ] Hard refresh page (Ctrl+F5)
-- [ ] Test splash screen shows all 8 ext modules
-- [ ] Test HTML preview with JavaScript executes
-- [ ] Test WPM package installs succeed
-- [ ] Test search shows inline message (no alert)
-- [ ] Test multi-step AI task (5 tool turns)
-- [ ] Test `edit_module` prompts for confirmation
-- [ ] Test auto-select model on connect
-- [ ] Test `ai-stop` cancels chat/stream
-- [ ] Test unknown command routes to AI (`hello`)

+   - mem — real-time memory usage (also in header)
+   - status — network, files, modules, Ollama connectivity
+
+4. **System journals:**
+   - debug.log — appended by debug panel VFS button (dedup by turn ID)
+   - current.log — system activity log with rotation
+   - Auto-save: terminal state auto-saves every 60s
+
+5. **When to use:**
+   - AI is behaving unexpectedly → debug to see tool calls
+   - User reports errors → logs 50 ERROR to see error entries
+   - Memory concerns → mem to check, health-check for full audit`),

+            sk('webdav-operations', 'How to use WebDAV cloud storage for backup, file sync, and remote file access', ['webdav', 'cloud', 'backup', 'sync', 'storage'], 'system',
+`## Steps
+1. **Configuration:**
+   - webdav-config — configure WebDAV endpoint URL and credentials
+   - Connection auto-tested on config; webdav-status shows connection health
+   - Uses per-user token stored in .token file on the server side
+
+2. **File operations:**
+   - webdav-ls [path] — list remote directory contents
+   - webdav-push <local-path> <remote-path> — upload file to WebDAV
+   - webdav-pull <remote-path> [local-path] — download file from WebDAV
+   - webdav-explorer — GUI file browser for WebDAV
+   - webdav-browser — CLI file browser for WebDAV
+
+3. **Backup & Restore:**
+   - webdav-backup — push full VFS snapshot to WebDAV (creates /backups/newos4-<date>.json)
+   - webdav-backup-list — list all remote backup snapshots
+   - webdav-restore <filename> — restore VFS from a remote backup snapshot
+
+4. **Status & Diagnostics:**
+   - webdav-status — connection status, last sync, space information
+   - If uploads fail: check webdav-config, ensure .token file is valid
+   - WebDAV runs on the same server (nginx with WebDAV module), no external dependency
+
+5. **When to use:**
+   - Before factory-reset: webdav-backup to store VFS remotely
+   - Cross-browser: webdav-push/pull to move files between instances
+   - User says "cloud backup" or "remote save" → webdav-backup`),
+
+            sk('security-and-safety', 'How to use WebX11 security levels, command blocking, and safety features', ['security', 'safety', 'blocking', 'permissions'], 'system',
+`## Steps
+1. **Security levels:**
+   - security-level <0-3> — set security level:
+     0 = Permissive (no blocks, no confirms — anything runs)
+     1 = Standard (unknown cmds → AI route, destructive → confirm, system → block)
+     2 = Paranoid (unknown cmds blocked entirely, destructive blocked)
+     3 = Audit (everything allowed, everything logged)
+   - Default: level 1
+   - security — show current level, blocked count, and stats
+
+2. **Command control:**
+   - cmd-allow <cmd> — whitelist a command from security checks
+   - cmd-deny <cmd> — blacklist/block a command entirely
+   - whitelist built-in: help, clear, ls, cat, pwd, whoami, df, free, top, ps, echo, date, env, history
+
+3. **What gets blocked at each level:**
+   - Unknown commands: Level 1 → AI routed, Level 2+ → blocked
+   - Destructive commands (delete, write, save, format, etc.): Level 1 → confirmation, Level 2+ → blocked
+   - System commands (reboot, shutdown, format, kill): Level 1+ → blocked
+   - Suspicious flags (--execute, --eval, --shell): Level 1+ → blocked
+
+4. **Safety checklist:**
+   - Check security: security shows your current level
+   - Before running risky commands: create a checkpoint first
+   - For temporary relax: security-level 0, then restore to 1
+   - For total lockdown before leaving: security-level 2
+
+5. **When to use:**
+   - User wants to lock down the terminal → security-level 2
+   - User wants to allow a blocked command → cmd-allow <cmd>
+   - Debugging strange behavior → verify security-level (user may have set it higher)`)

+# newOS4 — The Cognitive Operating System
+
+## Whitepaper v4.3.0-beta
+
+**Author:** Agando  
+**Status:** Architecture Draft  
+**Last Updated:** 2026-06-02
+
+---
+
+## 1. Abstract
+
+newOS4 is a **Cognitive Operating System** — an agentic, AI-native fabric where intelligence is treated not as an application layer but as the kernel's primary resource. Unlike traditional OSs that manage CPU cycles and memory pages, newOS4 manages **agentic workflows, semantic storage, and recursive self-optimization** as first-class primitives.
+
+The system is built on four pillars:
+
+| Pillar | Function |
+|---|---|
+| **Hyper-Modular Kernel** | Real-time self-rewriting drivers for task-specific optimization |
+| **A2A Protocol** | Standardized neural communication layer for agent negotiation |
+| **Neural VFS** | Semantic-based file storage where concepts replace paths |
+| **Recursive Self-Optimization** | Integrated feedback loops generating WPM patches to eliminate latency |
+
+---
+
+## 2. Motivation & Problem Space
+
+Modern operating systems (Linux, Windows, macOS) were designed for a world where:
+
+- Hardware resources (CPU, RAM, disk) are the binding constraints
+- Software is statically installed and version-pinned
+- The user is the sole intelligent agent at the keyboard
+
+This model breaks under three converging trends:
+
+1. **Agent proliferation** — LLM-based agents now outnumber human operators in production workflows
+2. **Dynamic compute** — Serverless, edge, and ephemeral compute require OS-level agility
+3. **Self-modifying code** — AI systems need to rewrite their own toolchain without reboot cycles
+
+newOS4 addresses all three by making **intelligence the kernel primitive** rather than an application afterthought.
+
+---
+

+
+### 3.2 The Trinity of Cognition
+
+newOS4 fuses three cognitive primitives:
+
+- **Perception** — Sensory input via agent sensors, web fetch, file I/O, and human chat
+- **Reasoning** — Contextual inference via LLM backbone (Ollama) + procedural memory (skills)
+- **Action** — Tool execution via sandboxed syscalls, WPM patches, and agent delegation
+
+Each maps to a classic OS concern: Perception = I/O, Reasoning = Scheduler, Action = Execution.
+
+---
+
+## 4. Pillar Deep Dives
+
+### 4.1 Hyper-Modular Kernel
+
+The kernel is **not** a monolithic binary. It is a collection of hot-swappable driver modules loaded and versioned through the **WPM (WebX11 Package Manager)**.
+
+**Properties:**
+- Each driver is an isolated ES module with defined syscall surfaces
+- Drivers can be loaded/unloaded/replaced at runtime
+- A self-rewrite daemon monitors performance telemetry and generates optimized driver variants
+
+**Warm-start guarantee:** The kernel caches the last N stable driver configurations in VFS. On cold boot, the "golden config" loads first, then adaptive drivers hot-patch in under 200ms.
+
+### 4.2 A2A Protocol
+
+Agent-to-Agent (A2A) is a standardized message format and transport layer designed for agent negotiation. See [A2A_protocol_spec.md](A2A_protocol_spec.md) for full specification.
+
+**Core tenets:**
+- No central broker — agents discover each other via VFS registrations
+- Messages are typed (request, response, broadcast, lease)
+- Each message carries a contract schema defining capabilities and constraints
+
+### 4.3 Neural VFS
+
+The Neural Virtual File System replaces hierarchical paths (`/home/user/docs/file.txt`) with semantic addressing (`concept://agentic-workflows/design-patterns/observer`).
+
+**Key innovation:** Path resolution is a two-stage process:
+1. **Semantic index** maps concept tokens to physical blocks
+2. **Context cache** keeps recent semantic lookups hot
+
+See [kernel_api.md](kernel_api.md) for VFS syscall reference.
+
+### 4.4 Recursive Self-Optimization
+
+The optimization loop:
+
+```
+Monitor → Profile → Diagnose → Patch → Test → Promote
+```
+
+- **Monitor:** Watchdog tracks syscall latency, agent response times, cache hit rates
+- **Profile:** Hot-path analysis identifies bottlenecks
+- **Diagnose:** LLM analyzes profile data and proposes WPM patch candidates
+- **Patch:** Patch is loaded into a sandboxed driver slot
+- **Test:** Synthetic workload validates improvement
+- **Promote:** On success, patch replaces production driver. On failure, rollback to golden config.
+
+---
+
+## 5. Roadmap
+
+### Phase 1 — Foundation ✅ COMPLETED
+
+What the whitepaper originally listed as 4 items has grown into 25+ completed features:
+
+**Original whitepaper items:**
+- ✅ WebX11 terminal — Terminal.js stable with Levenshtein fuzzy suggestions, security tiers, session persistence
+- ✅ VFS — virtual-fs.js fully functional: ls, cat, put, rm, upload, download with localStorage backend
+- ✅ Procedural Memory — 16 skill files + index.json, module-skills.js
+- ✅ Hot-reload module pipeline — module-loader.js + module-manager.js for dynamic load/unload
+
+**Built beyond the original scope:**
+- 32 modules (18 core + 14 ext), cleaned up from 42
+- Proxy API module — replaces dead DuckDuckGo/SearXNG/WebFetcher modules with `/api/search`, `/api/fetch`, `/api/stats` endpoints
+- Dynamic Prompt Engine — bare URL auto-fetch+summarize, question auto-search+AI answer
+- Ollama Manager — 89 models detected, supports cloud model routing
+- AI Tool System — function-calling loop with session_terminal tool, full agent workflow (module-aiassist.js)
+- ChatStudio integration — bridges terminal AI to chat UI
+- 9 theme presets — dark, light, amber, cyber, ocean, forest, monochrome, sunset, midnight
+- Help.html — 70KB, 3-tab layered documentation
+- Cheatsheet — printable A4 quick reference
+- Fuzzy suggestions — Levenshtein distance for typo correction
+- WebDAV browser UI — modern file-tree with bulk actions, inline rename, context menu, keyboard shortcuts
+- Voice module — speech and sound support
+- BusyBox — shell compatibility layer
+- Tutorial + Welcome tour — first-run onboarding
+- Ctrl+K quick command cards
+- Cryptogzip — encryption/compression utilities
+- File manager UI — graphical file browser
+- Utilities — calculator, diff, alias, finder, mindmap
+- WPM — WebX11 Package Manager (driver/module lifecycle)
+- Session nesting fix — recursive session bug resolved
+- Debug panel — live memory, events, errors, module health
+- Security layer — security-level 0-3 with command allowlist/denylist
+- Agent orchestration — agent-list, agent-register, lease-list, orchestrate
+- Skill-pack core — 12 skills, auto-load, seed/reload support
+
+### Phase 2 — Agentic Shift 🟡 IN PROGRESS (partial)
+
+**What's already built:**
+- ✅ AI tool-calling loop with 19+ tool definitions (filesystem, search, skills, module management)
+- ✅ session_terminal tool — zero-cost context access for terminal commands
+- ✅ Tool execution pipeline with error tracking and auto-skill creation on repeated failures
+- ✅ Ollama proxy — routes streaming chat and tool calls with cloud model support
+- ✅ Tool failure buffer — auto-flushes to localStorage for cross-session learning
+- ✅ Agent orchestration — agent-list, agent-register, lease-list, orchestrate commands
+- ✅ Agent registration via VFS — registry with name, model, capabilities metadata
+- ✅ Lease system — time-bound contracts with status tracking
+- ✅ Security layer — security-level 0-3, cmd-allow/cmd-deny, destructive action confirmation (120s countdown)
+- ✅ Debug panel — live memory/events/errors/module health monitoring
+- ✅ WebDAV modern browser — file-tree with bulk actions, inline rename, context menu, keyboard shortcuts
+- ✅ Debug panel — tool call visualization with persistent log
+- ✅ Skill-pack core — 12 skills auto-loaded on startup with seed/reload support
+- ✅ Chat cleaned to single /chat toggle overlay
+
+**What's still to build:**
+- Autonomous sub-agent spawning with task-specific roles
+- Agent lifecycle management (birth, sleep, death, reanimation)
+- A2A Agent-to-Agent protocol — standardized message bus for agent negotiation
+- Sandboxed execution contexts for sub-agents
+- Agent health monitoring and restart policies
+- Neural VFS concept:// path resolution
+
+### Phase 3 — Cognitive OS 🔴 NOT STARTED
+
+**On the roadmap:**
+- Global World Model integration — persistent semantic understanding of system state
+- Predictive resource allocation — anticipate agent needs before they arise
+- Cross-session persistent memory graphs — relational memory across all user sessions
+- Neural VFS — semantic path resolution (`concept://` paths) replacing hierarchical filesystem
+- Recursive self-optimization — automated WPM patches based on performance telemetry
+- Self-rewrite daemon — models hot-path bottlenecks and generates optimized driver variants
+- Cognitive shell — unified dashboard for multi-agent activity visualization
+
+**Implementation Plan:** `.hermes/plans/2026-06-02_phase3-cognitive-os.md`
+
+---
+
+## 6. Failure Modes & Risk Mitigation
+
+| Risk | Mitigation |
+|---|---|
+| **WPM loop thrash** | N-version golden config, max 3 patches/sec throttle |
+| **Cold-start latency** | Warm VFS cache + preloaded golden config |
+| **Agent contract deadlock** | Lease TTLs + timeout escalation to human |
+| **Semantic path collision** | Namespace registration + conflict resolution via A2A |
+| **Self-rewrite corruption** | Boot-time integrity check against signed golden config |
+
+---
+
+## 7. Related Work
+
+- **Plan 9** — Distributed, per-process namespaces (inspiration for VFS semantics)
+- **Erlang/OTP** — Actor model, hot code swapping (inspiration for agent lifecycle)
+- **NixOS** — Declarative configuration, rollback (inspiration for golden config model)
+- **Auto-GPT / BabyAGI** — Autonomous agent loops (precursors to recursive self-optimization)
+
+---
+
+## 8. Conclusion
+
+newOS4 is not an application. It is not a framework. It is an operating system designed from first principles for the age of cognitive computing. The architecture is intentionally minimal — four pillars, three phases, one north star: **Intelligence as the OS primitive.**

+description: How to use the agent registry, leases, and orchestrator for multi-agent workflows
+tags: [agents, orchestration, delegation, leases]
+category: system
+---
+## Steps
+1. **Agent Registry:**
+   - agent-list — list all registered agents (ID, type, capabilities, status)
+   - agent-register <type> <capabilities> — register a new agent (capabilities: comma-separated like "code,research")
+   - agent-unregister <id> — remove an agent
+   - agent-status <id> — detailed status including uptime, task history
+
+2. **Leases (time-bound contracts):**
+   - lease-create <agent-id> <ttl-seconds> — create a lease with watchdog timer
+   - lease-list — show active leases with remaining TTL
+   - lease-revoke <lease-id> — terminate a lease early
+   - lease-renew <lease-id> <ttl-seconds> — extend a lease
+
+3. **Orchestrator (spawn, delegate, kill):**
+   - orchestrator-spawn <type> <capabilities> — spawn a new agent automatically (registers + creates lease)
+   - orchestrator-kill <agent-id> — kill an agent (revokes lease + unregisters)
+   - orchestrate — list all active agents with their orchestrator state
+   - orchestrator-purge — kill all idle/expired agents
+   - orchestrator-status — full system status: active, idle, dead agents
+
+4. **AI tool integration:**
+   - AI tools list_agents, delegate_task, spawn_agent are available in the AI system prompt
+   - The AI can auto-spawn worker agents for sub-tasks
+   - Each agent gets its own VFS workspace at /agents/<agent-id>/
+
+5. **When to use:**
+   - User needs parallel task execution → orchestrator-spawn coder + researcher
+   - Time-bound automation → lease-create with short TTL
+   - System cleanup → orchestrator-purge to kill stale agents

+# Bug Tracking Workflow
+
+This skill provides a standardized way to track bugs using a JSON-based log file in the root directory.
+
+## 1. Initialize Bug Log
+If `/bugs.json` does not exist, create it with an empty array: `[]`.
+
+## 2. Reporting a Bug
+When a bug is found, append a new entry to `/bugs.json` with the following schema:
+- `id`: Unique incremental integer.
+- `title`: Brief summary of the issue.
+- `description`: Detailed steps to reproduce and expected vs actual behavior.
+- `status`: "open" | "in-progress" | "resolved" | "closed".
+- `severity`: "low" | "medium" | "high" | "critical".
+- `created_at`: Timestamp.
+- `updated_at`: Timestamp.
+
+## 3. Managing Bugs
+- **List Open Bugs**: Filter `/bugs.json` for entries where `status != "closed"`.
+- **Update Status**: Change the `status` and update the `updated_at` timestamp.
+- **Resolve**: Mark as "resolved" and add a `resolution` field explaining the fix.
+
+## 4. Verification
+Once a bug is marked "resolved", run existing tests or manually verify the fix before marking it "closed".

+description: How to use the debug panel, session logging, and terminal diagnostics
+tags: [debug, logging, diagnostics, troubleshooting]
+category: system
+---
+## Steps
+1. **Toggle debug panel:**
+   - debug — opens real-time debug panel showing last AI tool call, response time, and context
+   - Debug panel includes Copy, Export, and Write to VFS buttons
+   - Export: saves tool call log as timestamped JSON to downloads
+   - Write to VFS: appends debug data to /debug.log (dedup by turn ID)
+
+2. **Session logging:**
+   - logs [n] [LEVEL] — view last n log entries (optionally filtered by INFO/WARN/ERROR)
+   - logrotate — rotate current.log to dated archive (auto-cleans old logs beyond 10)
+   - Logs stored in /logs/ directory: current.log + dated archives
+   - Health check runs automatically after complex tasks
+
+3. **Diagnostic commands:**
+   - health-check — full audit: VFS size, modules, logs, trash, skills
+   - check — quick system health including module requirement status
+   - mem — real-time memory usage (also in header)
+   - status — network, files, modules, Ollama connectivity
+
+4. **System journals:**
+   - debug.log — appended by debug panel VFS button (dedup by turn ID)
+   - current.log — system activity log with rotation
+   - Auto-save: terminal state auto-saves every 60s
+
+5. **When to use:**
+   - AI is behaving unexpectedly → debug to see tool calls
+   - User reports errors → logs 50 ERROR to see error entries
+   - Memory concerns → mem to check, health-check for full audit

+description: How to use WebX11 security levels, command blocking, and safety features
+tags: [security, safety, blocking, permissions]
+category: system
+---
+## Steps
+1. **Security levels:**
+   - security-level <0-3> — set security level:
+     0 = Permissive (no blocks, no confirms — anything runs)
+     1 = Standard (unknown cmds → AI route, destructive → confirm, system → block)
+     2 = Paranoid (unknown cmds blocked entirely, destructive blocked)
+     3 = Audit (everything allowed, everything logged)
+   - Default: level 1
+   - security — show current level, blocked count, and stats
+
+2. **Command control:**
+   - cmd-allow <cmd> — whitelist a command from security checks
+   - cmd-deny <cmd> — blacklist/block a command entirely
+   - whitelist built-in: help, clear, ls, cat, pwd, whoami, df, free, top, ps, echo, date, env, history
+
+3. **What gets blocked at each level:**
+   - Unknown commands: Level 1 → AI routed, Level 2+ → blocked
+   - Destructive commands (delete, write, save, format, etc.): Level 1 → confirmation, Level 2+ → blocked
+   - System commands (reboot, shutdown, format, kill): Level 1+ → blocked
+   - Suspicious flags (--execute, --eval, --shell): Level 1+ → blocked
+
+4. **Safety checklist:**
+   - Check security: security shows your current level
+   - Before running risky commands: create a checkpoint first
+   - For temporary relax: security-level 0, then restore to 1
+   - For total lockdown before leaving: security-level 2
+
+5. **When to use:**
+   - User wants to lock down the terminal → security-level 2
+   - User wants to allow a blocked command → cmd-allow <cmd>
+   - Debugging strange behavior → verify security-level (user may have set it higher)

+# Task Management Workflow
+
+## 1. Initialization
+- Check if `/tasks.json` exists. If not, create it with an empty array: `[]`.
+
+## 2. Adding Tasks
+When a new task is identified:
+- **Define**: Task name, priority (Low, Medium, High), status (Todo, In-Progress, Done), and deadline.
+- **Action**: Read `tasks.json`, append the new task object, and write back to the file.
+
+## 3. Daily Planning/Review
+- **List**: Read `tasks.json` and filter for "Todo" or "In-Progress".
+- **Prioritize**: Sort tasks by priority (High > Medium > Low).
+- **Update**: Change status of tasks as they are completed.
+
+## 4. Maintenance
+- **Cleanup**: Archive "Done" tasks to `/tasks_archive.json` periodically to keep the main list lean.
+- **Audit**: Review overdue tasks and update deadlines or priorities.
+
+## Schema Reference
+```json
+{
+  "id": "unique-id",
+  "title": "Task name",
+  "priority": "High|Medium|Low",
+  "status": "Todo|In-Progress|Done",

+tags: [webdav, cloud, backup, sync, storage]
+category: system
+---
+## Steps
+1. **Configuration:**
+   - webdav-config — configure WebDAV endpoint URL and credentials
+   - Connection auto-tested on config; webdav-status shows connection health
+   - Uses per-user token stored in .token file on the server side
+
+2. **File operations:**
+   - webdav-ls [path] — list remote directory contents
+   - webdav-push <local-path> <remote-path> — upload file to WebDAV
+   - webdav-pull <remote-path> [local-path] — download file from WebDAV
+   - webdav-explorer — GUI file browser for WebDAV
+   - webdav-browser — CLI file browser for WebDAV
+
+3. **Backup & Restore:**
+   - webdav-backup — push full VFS snapshot to WebDAV (creates /backups/newos4-<date>.json)
+   - webdav-backup-list — list all remote backup snapshots
+   - webdav-restore <filename> — restore VFS from a remote backup snapshot
+
+4. **Status & Diagnostics:**
+   - webdav-status — connection status, last sync, space information
+   - If uploads fail: check webdav-config, ensure .token file is valid
+   - WebDAV runs on the same server (nginx with WebDAV module), no external dependency
+
+5. **When to use:**
+   - Before factory-reset: webdav-backup to store VFS remotely
+   - Cross-browser: webdav-push/pull to move files between instances
+   - User says "cloud backup" or "remote save" → webdav-backup
