+## Issue Assignment — The Lock Protocol
+
+**Rule: Assign before you code.**
+
+Before starting work on any issue, you **must** assign it to yourself. If an issue is already assigned to someone else, **do not submit a competing PR**.
+
+### For Humans
+
+1. Check the issue is unassigned
+2. Assign yourself via the Gitea UI (right sidebar → Assignees)
+3. Start coding
+
+### For Agents (Claude, Perplexity, Mimo, etc.)
+
+1. Before generating code, call the Gitea API to check assignment:
+   ```
+   GET /api/v1/repos/{owner}/{repo}/issues/{number}
+   → Check assignees array
+   ```
+2. If unassigned, self-assign:
+   ```
+   POST /api/v1/repos/{owner}/{repo}/issues/{number}/assignees
+   {"assignees": ["your-username"]}
+   ```
+3. If already assigned, **stop**. Post a comment offering to help instead.
+
+### Why This Matters
+
+On April 11, 2026, we found 12 stale PRs caused by Rockachopa and the `[claude]` auto-bot racing on the same issues. The auto-bot merged first, orphaning the manual PRs. Assignment-as-lock prevents this race condition.

-> CI enforcement pending runner restoration (#915)
+1. **Rebase before merge** — PRs must be up-to-date with `main`. If you have merge conflicts, rebase locally and force-push.
+2. **Reference the issue** — Use `Closes #NNN` in the PR body so Gitea auto-closes the issue on merge.
+3. **No bytecode** — Never commit `__pycache__/` or `.pyc` files. The `.gitignore` handles this, but double-check.
+4. **One feature per PR** — Avoid omnibus PRs that bundle multiple unrelated features. They're harder to review and more likely to conflict.

-### Default Reviewer Assignment
-
-All repositories must:
-- 🧑‍ Default reviewer: `@perplexity` (QA gate)
-- 🧑 Required reviewer: `@Timmy` for `hermes-agent/` only
-
-### Acceptance Criteria
-
-- [x] All four repositories have protection rules applied
-- [x] Default reviewers configured per matrix above
-- [x] This policy documented in all repositories
-- [x] Policy enforced for 72 hours with no unreviewed merges
-
-> This policy replaces all previous ad-hoc workflows. Any exceptions require written approval from @Timmy and @perplexity.
-All repositories enforce:
-- ✅ Require Pull Request for merge
-- ✅ Minimum 1 approval required
-- ✅ Dismiss stale approvals on new commits
-- ⚠️ Require CI to pass (CI runner pending for the-nexus)
-- ✅ Block force push to `main`
-- ✅ Block deletion of `main` branch
-
-## Review Requirement
-- 🧑‍ Default reviewer: `@perplexity` (QA gate)
-- 🧑 Required reviewer: `@Timmy` for `hermes-agent/` only
+---
 
 ## Workflow
-1. Create feature branch from `main`
-2. Submit PR with clear description
-3. Wait for @perplexity review
-4. Address feedback if any
-5. Merge after approval and passing CI
+
+1. Check the issue is unassigned → self-assign
+2. Check `FEATURES.yaml` for the relevant module
+3. Create feature branch from `main`
+4. Submit PR with clear description and `Closes #NNN`
+5. Wait for reviewer approval
+6. Rebase if needed, then merge
+
+### Emergency Exceptions
+
+Hotfixes require:
+- ✅ @Timmy approval
+- ✅ Post-merge documentation
+- ✅ Follow-up PR for full review
+
+---
+
+## Stale PR Policy
+
+A cron job runs every 6 hours and auto-closes PRs that are:
+1. **Conflicted** (not mergeable)
+2. **Superseded** by a merged PR that closes the same issue or implements the same feature
+
+Closed PRs receive a comment explaining which PR superseded them. If your PR was auto-closed but contains unique work, reopen it, rebase against `main`, and update the feature manifest.
+
+---

+# 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: 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.

-**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).
+**Why it works:** Single process. No split-brain failure modes. No Lobster state possible.

+**Research by:** Bezalel
+**Date:** 2026-04-07
+**Scope:** github.com/ai-tools — 205 repositories scanned
+
+## Summary
+
+The `ai-tools` GitHub org is a broad mirror/fork collection of 205 AI repos.
+~170 are media-generation tools with limited operational value for the fleet.
+7 tools are strongly relevant to our infrastructure, multi-agent orchestration,
+and sovereign compute goals.
+
+## Top 7 Recommendations
+
+### Priority 1 — Immediate
+
+- [ ] **edge-tts** — Free TTS fallback for Hermes (pip install edge-tts)
+  - Zero API key, uses Microsoft Edge online service
+  - Pair with local TTS (fish-speech/F5-TTS) for full sovereignty later
+  - Hermes integration: add as provider fallback in text_to_speech tool
+
+- [ ] **llama.cpp** — Standardize local inference across VPS nodes
+  - Already partially running on Alpha (127.0.0.1:11435)
+  - Serve Qwen2.5-7B-GGUF or similar for fast always-available inference
+  - Eliminate per-token cloud charges for batch workloads
+
+### Priority 2 — Short-term (2 weeks)
+
+- [ ] **A2A (Agent2Agent Protocol)** — Machine-native inter-agent comms
+  - Draft Agent Cards for each wizard (Bezalel, Ezra, Allegro, Timmy)
+  - Pilot: Ezra detects Gitea failure -> A2A delegates to Bezalel -> fix -> report back
+  - Framework-agnostic, Google-backed
+
+- [ ] **Llama Stack** — Unified LLM API abstraction layer
+  - Evaluate replacing direct provider integrations with Stack API
+  - Pilot with one low-risk tool (e.g., text summarization)
+
+### Priority 3 — Medium-term (1 month)
+
+- [ ] **bolt.new-any-llm** — Rapid internal tool prototyping
+  - Use for fleet health dashboard, Gitea PR queue visualizer
+  - Can point at local Ollama/llama.cpp for sovereign prototypes
+
+- [ ] **Swarm (OpenAI)** — Multi-agent pattern reference
+  - Don't deploy; extract design patterns (handoffs, routines, routing)
+  - Apply patterns to Hermes multi-agent architecture
+
+- [ ] **diagram-ai / diagrams** — Architecture documentation
+  - Supports Alexander's Master KT initiative
+  - `diagrams` (Python) for CLI/scripted, `diagram-ai` (React) for interactive
+
+## Skip List
+
+These categories are low-value for the fleet:
+- Image/video diffusion tools (~65 repos)
+- Colorization/restoration (~15 repos)
+- 3D reconstruction (~22 repos)
+- Face swap / deepfake tools
+- Music generation experiments

+Morrowind/OpenMW MCP Harness — GamePortal Protocol Implementation
+
+A harness for The Elder Scrolls III: Morrowind (via OpenMW) using MCP servers:
+- desktop-control MCP: screenshots, mouse/keyboard input
+- steam-info MCP: game stats, achievements, player count
+
+This harness implements the GamePortal Protocol:
+  capture_state() → GameState
+  execute_action(action) → ActionResult
+
+The ODA (Observe-Decide-Act) loop connects perception to action through
+Hermes WebSocket telemetry.
+
+World-state verification uses screenshots + position inference rather than
+log-only proof, per issue #673 acceptance criteria.
