+# Mission Bus
+
+The Mission Bus grounds the multi-agent teaming epic with a concrete, executable shared module.
+
+## What it adds
+- one unified mission stream for messages, checkpoints, and handoffs
+- role-based permissions for `lead`, `write`, `read`, and `audit`
+- cross-agent handoff packets so Agent A can checkpoint and Agent B can resume
+- declared isolation profiles for Level 1, Level 2, and Level 3 mission cells
+
+## Files
+- `nexus/mission_bus.py`
+- `config/mission_bus_profiles.json`
+
+## Example
+
+```python
+from nexus.mission_bus import MissionBus, MissionRole, load_profiles
+from pathlib import Path
+
+bus = MissionBus("mission-883", title="multi-agent teaming", config=load_profiles(Path("config/mission_bus_profiles.json")))
+bus.register_participant("timmy", MissionRole.LEAD)
+bus.register_participant("ezra", MissionRole.WRITE)
+checkpoint = bus.create_checkpoint("ezra", summary="checkpoint", state={"branch": "fix/883"})
+bus.handoff("ezra", "timmy", checkpoint.checkpoint_id, note="resume from here")
+packet = bus.build_resume_packet(bus.events[-1].handoff_id)
+```
+
+## Scope of this slice
+This slice does not yet wire a live transport or rootless container launcher.
+It codifies the mission bus contract, role permissions, handoff packet, and isolation profile surface so later work can execute against a stable interface.

 # SOUL.md Canonical Location Policy
 
-**Issue:** #1443 - decide: Establish SOUL.md canonical location (from Issue #1127 triage)  
-**Status:** ✅ DECIDED  
-**Canonical Location:** `timmy-home/SOUL.md`
+**Issue:** #1127 - Perplexity Evening Pass triage identified duplicate SOUL.md files causing duplicate PRs.
 
-## Decision
+## Current State
 
-**SOUL.md canonical location is `timmy-home/SOUL.md`.**
+As of 2026-04-14:
+- SOUL.md exists in `timmy-home` (canonical location)
+- SOUL.md was also in `timmy-config` (causing duplicate PR #377)
+
+## Problem
+
+The triage found:
+- PR #580 in timmy-home: "Harden SOUL.md against Claude identity hijacking"
+- PR #377 in timmy-config: "Harden SOUL.md against Claude identity hijacking" (exact same diff)
+
+This created confusion and wasted review effort on duplicate work.
+
+## Canonical Location Decision
+
+**SOUL.md canonical location: `timmy-home/SOUL.md`**
+
+### Rationale
+
+1. **Existing Practice:** PR #580 was approved in timmy-home, establishing it as the working location.
+
+2. **Repository Structure:** timmy-home contains core identity and configuration files:
+   - SOUL.md (Timmy's identity and values)
+   - CLAUDE.md (Claude configuration)
+   - Core documentation and policies
+
+3. **CLAUDE.md Alignment:** The CLAUDE.md file in the-nexus references timmy-home as containing core identity files.
 
-This decision was made based on:
-1. **Existing Practice:** PR #580 was approved in timmy-home
-2. **Repository Structure:** timmy-home contains core identity files
-3. **CLAUDE.md Alignment:** References timmy-home as containing core identity files
 4. **Separation of Concerns:**
    - `timmy-home`: Core identity, values, and configuration
    - `timmy-config`: Operational configuration and tools
    - `the-nexus`: 3D world and visualization
 
-## Current State
-
-### SOUL.md in the-nexus
-The current `SOUL.md` in the-nexus is already a reference pointer:
-
-```markdown
-# SOUL.md
-
-> **This file is a reference pointer.** The canonical SOUL.md lives in
-> [`timmy-home`](https://forge.alexanderwhitestone.com/Timmy_Foundation/timmy-home/src/branch/main/SOUL.md).
->
-> Do not duplicate identity content here. If this repo needs SOUL.md at
-> runtime, fetch it from timmy-home or use a submodule reference.
-```
-
-This is the correct approach - the-nexus should reference the canonical location, not duplicate content.
-
-### Historical Context
-- **PR #580 (timmy-home):** "Harden SOUL.md against Claude identity hijacking" - Approved
-- **PR #377 (timmy-config):** "Harden SOUL.md against Claude identity hijacking" - Closed as duplicate
-- Both PRs had identical diffs, causing confusion
-
-## Prevention Measures
-
-### 1. Documentation
-This policy document establishes the canonical location.
-
-### 2. CODEOWNERS Update
-Add SOUL.md to CODEOWNERS to require review for changes:
-
-```
-# SOUL.md requires review from @Timmy
-SOUL.md @Timmy
-timmy-home/SOUL.md @Timmy
-```
-
-### 3. PR Template Update
-Add reminder to PR template:
-
-```markdown
-## SOUL.md Changes
-- [ ] Changes are to `timmy-home/SOUL.md` (canonical location)
-- [ ] Not creating duplicate SOUL.md in other repositories
-- [ ] Updating reference pointers if needed
-```
-
-### 4. CI Check (Future)
-Add CI check to warn if SOUL.md is modified outside timmy-home.
-
 ## Implementation
 
 ### Immediate Actions
-1. **Verify timmy-home/SOUL.md exists** - ✅ Confirmed
-2. **Verify the-nexus/SOUL.md is reference pointer** - ✅ Confirmed
-3. **Update CODEOWNERS** - Add SOUL.md review requirements
-4. **Document policy** - This document
 
-### Future Actions
-1. **Check other repositories** - Ensure no duplicate SOUL.md files
-2. **Update documentation** - Reference this policy in CONTRIBUTING.md
-3. **Monitor for duplicates** - Regular checks for SOUL.md in wrong locations
+1. **Remove duplicate SOUL.md from timmy-config** (if it still exists)
+   - Check if `timmy-config/SOUL.md` exists
+   - If it does, remove it and update any references
+   - Ensure all documentation points to `timmy-home/SOUL.md`
+
+2. **Update CODEOWNERS** (if needed)
+   - Ensure SOUL.md changes require review from @Timmy
+   - Add explicit path for `timmy-home/SOUL.md`
+
+3. **Document in CONTRIBUTING.md**
+   - Add section about canonical file locations
+   - Specify that SOUL.md changes should only be made in timmy-home
+
+### Prevention Measures
+
+1. **Git Hooks or CI Checks**
+   - Warn if SOUL.md is created outside timmy-home
+   - Check for duplicate SOUL.md files across repos
+
+2. **Documentation Updates**
+   - Update all references to point to timmy-home/SOUL.md
+   - Ensure onboarding docs mention canonical location
+
+3. **Code Review Guidelines**
+   - Reviewers should check that SOUL.md changes are in timmy-home
+   - Reject PRs that modify SOUL.md in other repositories
 
 ## Verification
 
-### Check timmy-home/SOUL.md
+To verify canonical location:
+
 ```bash
-# Verify canonical location exists
-curl -s -H "Authorization: token $TOKEN" \
-  "https://forge.alexanderwhitestone.com/api/v1/repos/Timmy_Foundation/timmy-home/contents/SOUL.md"
+# Check if SOUL.md exists in timmy-home
+curl -H "Authorization: token $TOKEN" \
+  https://forge.alexanderwhitestone.com/api/v1/repos/Timmy_Foundation/timmy-home/contents/SOUL.md
+
+# Check if SOUL.md exists in timmy-config (should not)
+curl -H "Authorization: token $TOKEN" \
+  https://forge.alexanderwhitestone.com/api/v1/repos/Timmy_Foundation/timmy-config/contents/SOUL.md
 ```
 
-### Check for Duplicates
-```bash
-# Check all repositories for SOUL.md
-for repo in the-nexus timmy-config hermes-agent the-beacon; do
-  echo "Checking $repo..."
-  curl -s -H "Authorization: token $TOKEN" \
-    "https://forge.alexanderwhitestone.com/api/v1/repos/Timmy_Foundation/$repo/contents/SOUL.md" \
-    | jq -r '.name // "Not found"'
-done
-```
+## Future Considerations
 
-## Benefits
+1. **Symlink Approach:** Consider using a symlink in timmy-config pointing to timmy-home/SOUL.md if both locations are needed for technical reasons.
 
-### 1. Prevents Duplicate PRs
-- No more duplicate SOUL.md changes across repositories
-- Clear ownership and review process
+2. **Content Synchronization:** If SOUL.md content must exist in multiple places, implement automated synchronization with clear ownership.
 
-### 2. Clear Ownership
-- timmy-home owns SOUL.md
-- Changes require review from @Timmy
-
-### 3. Consistent Identity
-- Single source of truth for Timmy's identity
-- No divergence between repositories
-
-### 4. Easier Maintenance
-- One place to update SOUL.md
-- Clear review and approval process
-
-## Related Issues
-
-- **Issue #1127:** Perplexity Evening Pass triage (identified duplicate SOUL.md)
-- **Issue #1443:** This decision
-- **PR #580:** Approved SOUL.md changes in timmy-home
-- **PR #377:** Closed duplicate SOUL.md changes in timmy-config
-
-## Files
-
-- `SOUL.md` - Reference pointer to timmy-home (this repository)
-- `timmy-home/SOUL.md` - Canonical location
-- `docs/soul-canonical-location.md` - This policy document
+3. **Version Control:** Ensure all changes to SOUL.md go through proper review process in timmy-home.
 
 ## Conclusion
 
-**SOUL.md canonical location is established as `timmy-home/SOUL.md`.**
+Establishing `timmy-home/SOUL.md` as the canonical location:
+- ✅ Prevents duplicate PRs like #580/#377
+- ✅ Maintains clear ownership and review process
+- ✅ Aligns with existing repository structure
+- ✅ Reduces confusion and wasted effort
 
-This decision:
-- ✅ Prevents future duplicate PRs
-- ✅ Establishes clear ownership
-- ✅ Maintains consistent identity
-- ✅ Aligns with existing practice
+This policy should be documented in CONTRIBUTING.md and enforced through code review guidelines.
 
-**This issue can be closed.**

+- Repository cloning: May hit timeout on slow clones
+
+### Confidence Level
+- High confidence: 800+ commits, 150+ PRs
+- Medium confidence: 1,000+ commits, 200+ PRs
+- Low confidence: 1,200+ commits, 250+ PRs (requires all loops running clean)
