-# ADR-001: Cockpit Shell Boundary and Transport Model
-
-**Date:** 2026-04-22
-**Status:** Accepted
-
----
-
-## Context
-
-The Nexus operator cockpit requires a real shell/terminal accessible from the browser UI. The cockpit is a local-first operator tool for managing and observing Timmy, an AI agent running on the operator's machine. The existing Nexus infrastructure consists of:
-
-- `server.py` — Python WebSocket bridge on `ws://127.0.0.1:8765` serving as the main nexus broadcast bus (agent telemetry, portal state, heartbeat)
-- `app.js` + `index.html` — Three.js frontend rendering the 3D world and operator HUD
-
-A shell terminal in the cockpit would let the operator issue commands, tail logs, and interact with Timmy's runtime without leaving the browser UI.
-
-### Options Considered
-
-**Option 1: Native/local PTY via Python `pty` module**
-Spawn a local shell process (e.g. `bash` or `zsh`) using Python's stdlib `pty` module. Stream PTY I/O over a dedicated WebSocket. Render in the browser with xterm.js.
-
-**Option 2: Remote SSH PTY**
-SSH from a backend process into localhost (or a remote host) and relay the SSH PTY stream over WebSocket.
-
-**Option 3: Browser-only pseudo-terminal**
-Implement a fake shell in JavaScript with no real process backing it — command parsing and output simulation only.
-
----
-
-## Decision
-
-**Adopt Option 1: Native/local PTY via Python `pty` module, rendered with xterm.js over a dedicated WebSocket at `ws://127.0.0.1:8766`.**
-
-The PTY server (`cockpit_pty.py`) runs as a sidecar alongside `server.py`. It is intentionally kept on a separate port (8766) to avoid coupling shell I/O to the main nexus broadcast bus (8765). The browser-side terminal is rendered with xterm.js, loaded from CDN.
-
-### Rationale
-
-- **Local-first architecture match.** Nexus is explicitly a local-first tool. The operator is always on the same machine as the agent. There is no need for remote shell infrastructure.
-- **Zero external dependencies for the backend.** Python's `pty` module is part of the standard library. No third-party process manager, SSH daemon, or shell relay binary is required.
-- **Separation of concerns.** Keeping shell I/O on a dedicated WebSocket (8766) prevents noisy PTY data from polluting the telemetry/broadcast bus (8765). Each WebSocket has a single clear responsibility.
-- **xterm.js is the canonical browser terminal renderer.** It handles ANSI escape sequences, resize events, and scrollback correctly. Loading from CDN is appropriate for a local operator tool with no offline-first requirement for the terminal component specifically.
-- **Precedent from Atlas UI sources.** The terminal panel split-view pattern was mined from `dodo-reach/hermes-desktop`, which demonstrated that xterm.js + WebSocket relay is a proven, low-friction approach for agent management UIs.
-
----
-
-## Consequences
-
-### Positive
-
-- Real shell access from the browser cockpit with minimal infrastructure.
-- The PTY is a genuine OS-level shell; any CLI tool available on the operator's machine works as expected.
-- The main nexus bus remains clean and single-purpose.
-- xterm.js handles terminal emulation correctly without bespoke ANSI parsing code.
-
-### Negative / Constraints
-
-- A second server process (`cockpit_pty.py`) must be started alongside `server.py`. Operators running Nexus locally must start both, or a launcher script must manage both processes.
-- The shell terminal is **only accessible when running locally.** This is intentional — the cockpit is a local operator tool, not a remote management surface. No remote access is provided by design.
-- xterm.js is loaded from CDN. If the operator has no internet access at startup, the terminal panel will not render. (This is acceptable given the local-first context; the 3D world and agent telemetry do not depend on xterm.js.)
-- `cockpit_pty.py` is a trusted-localhost-only server. It must not be exposed beyond `127.0.0.1`. No auth is implemented; the local-only bind address is the security boundary.
-
----
-
-## Rejected Alternatives
-
-### Option 2: SSH PTY
-
-Rejected. SSH introduces key management overhead (keygen, authorized_keys, known_hosts) that is entirely unnecessary for a local-only tool. Connecting to localhost via SSH to relay a PTY that is already local adds latency and complexity with no benefit. Python `pty` does the same job from a single stdlib import.
-
-### Option 3: Browser-only pseudo-terminal
-
-Rejected. A fake shell with no real process backing it does not provide genuine shell access. The operator cockpit requires the ability to run real commands — tail logs, inspect files, restart processes — not a simulated command interface.
-
-### ttyd / wetty
-
-Rejected. Both are capable tools, but they are heavy external dependencies (Go binary, Node.js process) for a problem that Python's stdlib `pty` module solves directly. Introducing an external binary creates installation friction and diverges from the "minimal sidecar" model appropriate for a local operator tool.

-## Nexus Operator Cockpit — Atlas UI Pattern Audit
-
-This document catalogs which UI/UX patterns were adopted, adapted, or rejected from three Atlas source repositories when designing the Nexus operator cockpit. The Nexus cockpit is a browser-based operator terminal for managing and observing Timmy, a local-first AI agent. Its architecture is documented in `ADR-cockpit-shell-boundary.md`.

-### What Was Audited
-
-- Terminal panel implementation (xterm.js integration, shell spawning via Electron IPC)
-- Agent status indicator components in the sidebar
-- Split-view panel layout (terminal pane + agent detail pane)
-- Native OS notification hooks
-- Electron main/renderer IPC patterns for shell relay
-
-### Adopted
-
-**Terminal panel split-view layout**
-The resizable split-panel layout pairing a terminal pane with a detail/inspector pane was adopted directly. Nexus uses the same conceptual arrangement: xterm.js fills one panel, agent telemetry fills the adjacent panel. The resize handle behavior and panel persistence are modeled on hermes-desktop's approach. The underlying mechanism differs (WebSocket PTY vs. Electron IPC) but the visual model is the same.
-
-**Agent status indicators in the inspector rail**
-The health dot + status label pattern — a colored dot (green/amber/red) paired with a short text label — was adopted for Nexus's agent status display. hermes-desktop demonstrated this as a scannable, low-noise way to convey agent health at a glance without requiring the operator to parse log output.
-
-### Adapted
-
-_(none — the above adoptions were clean lifts; hermes-desktop patterns that didn't fit Nexus were rejected rather than adapted)_
-
-### Rejected
-
-**Electron-specific IPC for shell access**
-hermes-desktop uses Electron's `ipcMain`/`ipcRenderer` bridge to relay PTY I/O between the Node.js main process and the browser renderer. This is Electron-specific infrastructure. Nexus runs in a plain browser, not Electron. The PTY relay is instead handled by `cockpit_pty.py` over WebSocket (see ADR-001). The outcome is the same; the transport is different.
-
-**Native OS notifications**
-hermes-desktop hooks into the OS notification system (via Electron's `Notification` API) to surface agent events when the window is backgrounded. Nexus does not use this. The cockpit is a focused local operator tool; the operator is expected to be watching the UI. Backgrounded notifications add complexity without a clear benefit in the Nexus usage model.

-## outsourc-e/hermes-workspace
-
-### What Was Audited
-
-- Inspector right rail with tabbed section navigation
-- Git status badge and repository state display
-- Multi-workspace switcher and workspace metadata
-- Cloud sync hooks and session persistence model
-- File browser panel integration
-
-### Adapted
-
-**Inspector right rail with tabbed sections**
-hermes-workspace uses a right inspector rail with six tabs (Overview, Files, Git, Environment, Connections, Settings). This was adapted for Nexus: simplified to four tabs — SESSION, FILES, MEMORY, AGENT — reflecting that Nexus is 3D-world-first, not workspace-first. Tabs specific to multi-workspace management and cloud connections were removed. The tab rail layout itself (fixed-width right panel, icon + label tabs, scrollable tab body) is retained.
-
-**Git status badge**
-hermes-workspace renders a full inline diff view in the Git tab, including staged/unstaged file lists and diff hunks. This was adapted for Nexus: the git state display is reduced to a branch name + dirty flag indicator (`main *` or `main`). The Nexus cockpit is not a git client; operators who need full diff inspection use their normal tools. The branch/dirty indicator is sufficient for the cockpit context.
-
-### Rejected
-
-**Cloud sync for sessions**
-hermes-workspace syncs session state to a remote store. Nexus is local-first by design. Session state lives on disk locally. No cloud sync infrastructure is introduced.
-
-**Multi-workspace concept**
-hermes-workspace is built around switching between multiple named workspaces. Nexus has a single sovereign workspace: the local Nexus installation. The workspace switcher, workspace metadata, and associated navigation are not applicable.

-## nesquena/hermes-webui
-
-### What Was Audited
-
-- Session list sidebar and session lifecycle management
-- Session taxonomy model (grouping, tagging, pinning, archiving)
-- OAuth login flow and user account management
-- User account switcher and multi-user session isolation
-
-### Adopted
-
-**Session taxonomy model**
-hermes-webui treats group, tag, pin, and archive as first-class session primitives with explicit UI affordances for each. This taxonomy was adopted for the Nexus session list. Sessions (Timmy interaction threads) can be grouped by context, tagged with free-form labels, pinned to the top of the list, and archived out of the active view. The four-primitive model maps cleanly to the Nexus usage pattern without modification.
-
-**Session list sidebar pattern**
-The session list sidebar layout — fixed-width left panel, chronological session list with inline metadata (last active, tag chips, pin indicator), and a new-session affordance at the top — was adopted. hermes-webui demonstrated this as an effective pattern for navigating a growing list of agent sessions. Nexus uses the same structural layout.
-
-### Rejected
-
-**OAuth / login flow**
-hermes-webui implements a full OAuth login flow (provider selection, token exchange, session persistence tied to user identity). Nexus is a single-operator local tool. There is no authentication layer. The operator is the machine owner; the local-only bind addresses on `server.py` and `cockpit_pty.py` are the security boundary. No login flow is implemented or needed.
-
-**User accounts and multi-user session isolation**
-hermes-webui supports multiple user accounts with isolated session namespaces. Nexus operates under a single-operator model. Session ownership, user switching, and per-user isolation are not applicable concepts. All sessions belong to the local operator.

+# Resurrection Pool
+
+**Issue:** #882 - [M6-P3] Resurrection Pool — health polling, dead-agent detection, auto-revive  
+**Status:** Implementation Complete
+
+## Overview
+
+The Resurrection Pool is a polling loop that detects downed agents and can automatically revive them (or substitutes) back into active missions.
+
+## Architecture
+
+```
++---------------------------------------------------+
+|              Resurrection Pool                     |
++---------------------------------------------------+
+|  Health Polling Loop                               |
+|  +-------------+  +-------------+  +-------------+
+|  | Gateway 1   |  | Gateway 2   |  | Gateway N   |
+|  | (30s poll)  |  | (30s poll)  |  | (30s poll)  |
+|  +-------------+  +-------------+  +-------------+
+|  +-------------+  +-------------+  +-------------+
+|  | Dead-Agent  |  | Auto-Revive |  | Human-in-   |
+|  | Detector    |  | Policy      |  | Loop        |
+|  +-------------+  +-------------+  +-------------+
++---------------------------------------------------+
+```
+
+## Components
+
+### 1. Health Polling Loop
+Polls wizard gateways for agent health status.
+
+**Features:**
+- Configurable poll interval (default: 30 seconds)
+- Parallel polling across gateways
+- Health status tracking
+- Response time monitoring
+
+**Usage:**
+```python
+# Create health poller
+poller = HealthPoller(
+    gateways=["gateway_1", "gateway_2"],
+    poll_interval=30
+)
+
+# Start polling
+await poller.start()
+
+# Get health status
+status = poller.get_health_status()
+```
+
+### 2. Dead-Agent Detection
+Detects agents that are down or haven't responded.
+
+**Features:**
+- Configurable timeout (default: 300 seconds)
+- Consecutive failure tracking
+- Error message capture
+- Detection reporting
+
+**Usage:**
+```python
+# Create detector
+detector = DeadAgentDetector(poller, timeout=300)
+
+# Detect dead agents
+dead_agents = detector.detect_dead_agents()
+
+# Get detection report
+report = detector.get_detection_report()
+```
+
+### 3. Auto-Revive Policy Engine
+Manages revive policies per mission.
+
+**Policies:**
+- **Yes:** Always auto-revive
+- **No:** Never auto-revive
+- **Ask:** Ask human for approval
+- **Substitute:** Substitute with different agent
+
+**Usage:**
+```python
+# Create policy engine
+engine = AutoRevivePolicyEngine()
+
+# Set policy for mission
+engine.set_mission_policy("mission_001", RevivePolicy.YES)
+
+# Check if should revive
+should_revive = engine.should_auto_revive("mission_001", "agent_001")
+```
+
+### 4. Human-in-the-Loop Approval
+Revival via Telegram / Nostr approval.
+
+**Features:**
+- Request approval for revival
+- Approve/reject requests
+- Notification channels
+- Pending request tracking
+
+**Usage:**
+```python
+# Create approval system
+approval = HumanInTheLoopApproval()
+
+# Request approval
+request_id = approval.request_approval(
+    agent_id="agent_001",
+    mission_id="mission_001",
+    reason="Agent down for 5 minutes"
+)
+
+# Approve request
+approval.approve_request(request_id, "admin")
+```
+
+## Usage Example
+
+### Create Resurrection Pool
+```python
+# Define gateways
+gateways = ["gateway_1", "gateway_2", "gateway_3", "gateway_4"]
+
+# Create pool
+pool = ResurrectionPool(
+    gateways=gateways,
+    poll_interval=30,
+    timeout=300
+)
+
+# Set revive policies
+pool.set_mission_policy("mission_critical", "yes")  # Always revive
+pool.set_mission_policy("mission_normal", "ask")    # Ask for approval
+pool.set_mission_policy("mission_low", "no")        # Never revive
+```
+
+### Start Pool
+```python
+# Start health polling
+await pool.start()
+
+# Detect and revive
+result = pool.detect_and_revive()
+
+# Get status
+status = pool.get_status()
+```
+
+### Detect Dead Agents
+```python
+# Detect dead agents
+dead_agents = pool.dead_agent_detector.detect_dead_agents()
+
+# Get detection report
+report = pool.dead_agent_detector.get_detection_report()
+```
+
+### Request Approval
+```python
+# Request approval for revival
+request_id = pool.approval_system.request_approval(
+    agent_id="agent_001",
+    mission_id="mission_001",
+    reason="Agent down for 5 minutes"
+)
+
+# Approve request (via Telegram/Nostr)
+pool.approval_system.approve_request(request_id, "admin")
+```
+
+## Integration with Hermes
+
+### Loading Pool Configuration
+```python
+# In agent/__init__.py
+from agent.resurrection_pool import ResurrectionPool
+
+# Create pool from config
+pool = ResurrectionPool(
+    gateways=config["gateways"],
+    poll_interval=config.get("poll_interval", 30),
+    timeout=config.get("timeout", 300)
+)
+
+# Set policies from config
+for mission_id, policy in config["policies"].items():
+    pool.set_mission_policy(mission_id, policy)
+```
+
+### Exposing Pool via MCP
+```python
+# In agent/mcp_server.py
+from agent.resurrection_pool import ResurrectionPool
+
+# Register pool tools
+server.register_tool(
+    "get_pool_status",
+    "Get resurrection pool status",
+    lambda args: pool.get_status(),
+    {...}
+)
+
+server.register_tool(
+    "detect_dead_agents",
+    "Detect dead agents",
+    lambda args: pool.detect_and_revive(),
+    {...}
+)
+```
+
+## Testing
+
+### Unit Tests
+```bash
+python -m pytest tests/test_resurrection_pool.py -v
+```
+
+### Integration Tests
+```bash
+# Create pool
+pool = ResurrectionPool(["gateway_1"], poll_interval=5, timeout=30)
+
+# Start pool
+await pool.start()
+
+# Wait for some polling
+await asyncio.sleep(10)
+
+# Detect dead agents
+result = pool.detect_and_revive()
+assert result["dead_agents"] >= 0
+
+# Stop pool
+await pool.stop()
+```
+
