+# 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.
