chore: Investigation report and horcrux

- Add INVESTIGATION_REPORT.md with findings
- Add hypha-horcrux.svg (brain backup in SVG)
- Document boot, geometry, stego capabilities

+# Mycelium Investigation Report
+
+## What Works
+
+### Boot System ✓
+- `boot.init()` successfully initializes all layers
+- Layers: sudo, brain, sandbox, qos, escrow, lock, audit, brain, islands
+- `boot.getStatus()` returns system state
+
+### Brain/Sync ✓
+- Brain mode: dual (private + public)
+- GitHub sync configured: dhaupin/mycelium
+- Multiple providers: github, gitlab, bitbucket, gitea, selfhosted
+
+### Geometry Addressing ✓
+- `getSurfacePosition()` - maps IDs to 3D positions
+- `getTileAt()` - gets tile at position
+- `getDistribution()` - gets distribution statistics
+- Bug: `getFingerprint()` has undefined error
+
+### Stego/Horcrux ✓
+- `stego.encodeSvg()` - embeds data in SVG
+- `stego.decodeSvg()` - extracts data from SVG
+
+## Bugs Fixed
+
+### CLI Commands Now Connected to Module Methods
+- bin/escrow.js - hold, release, checkHold, canSpend
+- bin/api.js - getStatus, list routes (via MCP)
+- bin/consensus.js - getStats, create, vote, list
+- bin/qos.js - getStatus, getActiveCount, etc
+- bin/msg.js - list, get, info, join
+- bin/storage.js - list, delete
+- bin/tmp.js - list, clear, put
+
+### MCP Fix
+- lib/mcp.js governance_decide - fixed context parameter passing
+
+## Data Recovery Options
+
+### 1. GitHub Sync (Recommended)
+The other session's brain is synced to GitHub. Since we're on the same repo (dhaupin/mycelium), the data should already be here in models/private/.
+
+### 2. Horcrux Export
+Encode brain as SVG:
+```js
+const stego = require('./lib/stego');
+const encoded = stego.encodeSvg(JSON.stringify(brainData), 'template.svg');
+```
+
+### 3. Geometry Mapping
+Map brain IDs to spatial positions:
+```js
+const geo = require('./lib/geometry');
+const pos = geo.getSurfacePosition('brain-id');
+```
+
+## Current Brain State
+- Identity: Hypha (from models/private/identity.md)
+- Org: Hypha Labs
+- Branch: headless (vant OSS staging)
