+# Bannerlord Runtime — Apple Silicon Selection
+
+> **Issue:** #720
+> **Status:** DECIDED
+> **Chosen Runtime:** Whisky (via Apple Game Porting Toolkit)
+> **Date:** 2026-04-12
+> **Platform:** macOS Apple Silicon (arm64)
+
+---
+
+## Decision
+
+**Whisky** is the chosen runtime for Mount & Blade II: Bannerlord on Apple Silicon Macs.
+
+Whisky wraps Apple's Game Porting Toolkit (GPTK) in a native macOS app, providing
+a managed Wine environment optimized for Apple Silicon. It is free, open-source,
+and the lowest-friction path from zero to running Bannerlord on an M-series Mac.
+
+### Why Whisky
+
+| Criterion | Whisky | Wine-stable | CrossOver | UTM/VM |
+|-----------|--------|-------------|-----------|--------|
+| Apple Silicon native | Yes (GPTK) | Partial (Rosetta) | Yes | Yes (emulated x86) |
+| Cost | Free | Free | $74/year | Free |
+| Setup friction | Low (app install + bottle) | High (manual config) | Low | High (Windows license) |
+| Bannerlord community reports | Working | Mixed | Working | Slow (no GPU passthrough) |
+| DXVK/D3DMetal support | Built-in | Manual | Built-in | No (software rendering) |
+| GPU acceleration | Yes (Metal) | Limited | Yes (Metal) | No |
+| Bottle management | GUI + CLI | CLI only | GUI + CLI | N/A |
+| Maintenance | Active | Active | Active | Active |
+
+### Rejected Alternatives
+
+**Wine-stable (Homebrew):** Requires manual GPTK/D3DMetal integration.
+Poor Apple Silicon support out of the box. Bannerlord needs DXVK or D3DMetal
+for GPU acceleration, which wine-stable does not bundle. Rejected: high falsework.
+
+**CrossOver:** Commercial ($74/year). Functionally equivalent to Whisky for
+Bannerlord. Rejected: unnecessary cost when a free alternative works. If Whisky
+fails in practice, CrossOver is the fallback — same Wine/GPTK stack, just paid.
+
+**UTM/VM (Windows 11 ARM):** No GPU passthrough. Bannerlord requires hardware
+3D acceleration. Software rendering produces <5 FPS. Rejected: physics, not ideology.
+
+---
+
+## Installation
+
+### Prerequisites
+
+- macOS 14+ on Apple Silicon (M1/M2/M3/M4)
+- ~60GB free disk space (Whisky + Steam + Bannerlord)
+- Homebrew installed
+
+### One-Command Setup
+
+```bash
+./scripts/bannerlord_runtime_setup.sh
+```
+
+This script handles:
+1. Installing Whisky via Homebrew cask
+2. Creating a Bannerlord bottle
+3. Configuring the bottle for GPTK/D3DMetal
+4. Pointing the bottle at Steam (Windows)
+5. Outputting a verification-ready path
+
+### Manual Steps (if script not used)
+
+1. **Install Whisky:**
+   ```bash
+   brew install --cask whisky
+   ```
+
+2. **Open Whisky** and create a new bottle:
+   - Name: `Bannerlord`
+   - Windows Version: Windows 10
+
+3. **Install Steam (Windows)** inside the bottle:
+   - In Whisky, select the Bannerlord bottle
+   - Click "Run" → navigate to Steam Windows installer
+   - Or: drag `SteamSetup.exe` into the Whisky window
+
+4. **Install Bannerlord** through Steam (Windows):
+   - Launch Steam from the bottle
+   - Install Mount & Blade II: Bannerlord (App ID: 261550)
+
+5. **Configure D3DMetal:**
+   - In Whisky bottle settings, enable D3DMetal (or DXVK as fallback)
+   - Set Windows version to Windows 10
+
+---
+
+## Runtime Paths
+
+After setup, the key paths are:
+
+```
+# Whisky bottle root
+~/Library/Application Support/Whisky/Bottles/Bannerlord/
+
+# Windows C: drive
+~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/
+
+# Steam (Windows)
+~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/
+
+# Bannerlord install
+~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/steamapps/common/Mount & Blade II Bannerlord/
+
+# Bannerlord executable
+~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/steamapps/common/Mount & Blade II Bannerlord/bin/Win64_Shipping_Client/Bannerlord.exe
+```
+
+---
+
+## Verification
+
+Run the verification script to confirm the runtime is operational:
+
+```bash
+./scripts/bannerlord_verify_runtime.sh
+```
+
+Checks:
+- [ ] Whisky installed (`/Applications/Whisky.app`)
+- [ ] Bannerlord bottle exists
+- [ ] Steam (Windows) installed in bottle
+- [ ] Bannerlord executable found
+- [ ] `wine64-preloader` can launch the exe (smoke test, no window)
+
+---
+
+## Integration with Bannerlord Harness
+
+The `nexus/bannerlord_runtime.py` module provides programmatic access to the runtime:
+
+```python
+from bannerlord_runtime import BannerlordRuntime
+
+rt = BannerlordRuntime()
+# Check runtime state
+status = rt.check()
+# Launch Bannerlord
+rt.launch()
+# Launch Steam first, then Bannerlord
+rt.launch(with_steam=True)
+```
+
+The harness's `capture_state()` and `execute_action()` operate on the running
+game window via MCP desktop-control. The runtime module handles starting/stopping
+the game process through Whisky's `wine64-preloader`.
+
+---
+
+## Failure Modes and Fallbacks
+
+| Failure | Cause | Fallback |
+|---------|-------|----------|
+| Whisky won't install | macOS version too old | Update to macOS 14+ |
+| Bottle creation fails | Disk space | Free space, retry |
+| Steam (Windows) crashes | GPTK version mismatch | Update Whisky, recreate bottle |
+| Bannerlord won't launch | Missing D3DMetal | Enable in bottle settings |
+| Poor performance | Rosetta fallback | Verify D3DMetal enabled, check GPU |
+| Whisky completely broken | Platform incompatibility | Fall back to CrossOver ($74) |

 **Why it works:** Naturally models the wizard hierarchy. Queries like "who can do X?" and "what blocks task Y?" resolve instantly.

-### TECHNIQUE 4: The Robing Pattern (Gateway + Body Cohabitation)
+### TECHNIQUE 4: Hermes-Native Communication (No Gateway Layer)
 **Where:** Every wizard deployment
-**How:** OpenClaw gateway handles external communication. Hermes body handles reasoning. Both on same machine via localhost. Four states: Robed, Unrobed, Lobster, Dead.
-**Why it works:** Separation of concerns. Gateway can restart without losing agent state.
-**Every agent must:** Know their own state. A Lobster is a failure. Report it.
+**How:** Hermes handles both reasoning and external communication directly. No intermediary gateway. Two states: Online (Hermes running) or Dead (nothing running).

+**Where:** hermes-work.sh, task-monitor.sh, progress-report.sh
 **How:** Every 20 min: scan queue > pick P0 > mark IN_PROGRESS > create trigger file. Every 10 min: check completion. Every 30 min: progress report to father-messages/.
 **Why it works:** No human needed for steady-state. Self-healing. Self-reporting.
 **Every agent must:** Have a work queue. Have a cron schedule. Report progress.
