+# 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.

-# Preventing Rubber-Stamping of PRs
-
-**Issue:** #1445 - process: Prevent rubber-stamping of PRs with no changes  
-**Problem:** PRs with no changes (zombie PRs) are being approved without actual review
-
-## What is Rubber-Stamping?
-
-Rubber-stamping occurs when:
-1. A PR has 0 additions, 0 deletions, and 0 files changed (zombie PR)
-2. Reviewers approve the PR without noticing it has no changes
-3. The PR gets merged despite adding no value
-
-This is a serious process issue because:
-- It wastes reviewer time
-- It creates false sense of review quality
-- It allows zombie PRs to appear reviewed
-- It clutters the PR backlog
-
-## Prevention Measures
-
-### 1. CI Check (`.gitea/workflows/check-pr-changes.yml`)
-Automated check that runs on every PR:
-- Detects PRs with no changes
-- Blocks merge if PR is a zombie
-- Provides clear error messages
-
-**What it checks:**
-- PR has additions, deletions, or file changes
-- Commits contain actual changes
-- No empty diffs
-
-**When it runs:**
-- On PR open
-- On PR synchronize (new commits)
-- On PR reopen
-
-### 2. PR Template (`.github/PULL_REQUEST_TEMPLATE.md`)
-Updated PR template with reviewer guidelines:
-- Clear checklist for reviewers
-- Explicit instructions to check for changes
-- Warning against rubber-stamping
-
-**Reviewer requirements:**
-1. Verify PR has actual changes
-2. Changes match description
-3. Code quality review
-4. Tests are adequate
-5. Documentation is updated
-
-### 3. Zombie PR Detection Script (`bin/check_zombie_prs.py`)
-Script to scan for zombie PRs:
-- Check all open PRs in repositories
-- Identify PRs with no changes
-- Generate reports
-
-**Usage:**
-```bash
-# Scan all repositories
-python bin/check_zombie_prs.py
-
-# Scan specific repositories
-python bin/check_zombie_prs.py --repos the-nexus timmy-home
-
-# Generate report
-python bin/check_zombie_prs.py --report
-
-# JSON output
-python bin/check_zombie_prs.py --json
-```
-
-## How to Use
-
-### For CI/CD
-The workflow runs automatically on all PRs. No setup needed.
-
-### For Developers
-1. **Before creating PR:**
-   - Ensure you have actual changes
-   - Test your changes locally
-   - Don't create PRs with no changes
-
-2. **When reviewing PRs:**
-   - Check that PR has additions, deletions, or file changes
-   - Verify changes match the PR description
-   - Don't approve PRs with no changes
-
-3. **If you find a zombie PR:**
-   - Add a comment explaining it has no changes
-   - Request changes or close the PR
-   - Don't approve it
-
-### For Agents (AI Workers)
-Before creating a PR:
-```bash
-# Check if you have changes
-git status
-git diff --stat
-
-# If no changes, don't create PR
-# If changes exist, create PR
-```
-
-## Examples
-
-### Zombie PR Detected
-```
-❌ ERROR: PR has no changes!
-
-This PR has 0 additions, 0 deletions, and 0 files changed.
-This is a 'zombie PR' that should not be merged.
-
-Rubber-stamping (approving PRs with no changes) is prohibited.
-Reviewers must verify that PRs contain actual changes.
-
-If this is a mistake, please add actual changes to the PR.
-If this PR is not needed, please close it.
-```
-
-### Valid PR
-```
-✅ PR has changes:
- README.md | 10 ++++++++++
- 1 file changed, 10 insertions(+)
-
-Summary:
-  Files changed: 1
-  Additions: 10
-  Deletions: 0
-```
-
-## Related Issues
-
-- **Issue #1127:** Perplexity Evening Pass triage (identified rubber-stamping)
-- **Issue #1445:** This implementation
-- **PR #359:** Example of rubber-stamping (3 approvals on empty PR)
-
-## Prevention Strategy
-
-### 1. **Automated Checks**
-- CI workflow blocks zombie PRs
-- Pre-commit hooks validate changes
-- Automated scanning for zombie PRs
-
-### 2. **Process Guidelines**
-- Updated PR template with reviewer guidelines
-- Clear instructions to check for changes
-- Training on rubber-stamping prevention
-
-### 3. **Monitoring**
-- Regular scans for zombie PRs
-- Reports on rubber-stamping incidents
-- Continuous improvement of prevention measures
-
-## Files Added
-
-1. `.gitea/workflows/check-pr-changes.yml` - CI workflow
-2. `.github/PULL_REQUEST_TEMPLATE.md` - Updated PR template
-3. `bin/check_zombie_prs.py` - Zombie PR detection script
-4. `docs/rubber-stamping-prevention.md` - This documentation
-
-## Testing
-
-Test the CI workflow:
-```bash
-# Create a test PR with no changes
-git checkout -b test/zombie-pr
-git commit --allow-empty -m "test: empty commit"
-git push origin test/zombie-pr
-# Create PR and watch CI fail
-```
-
-Test the detection script:
-```bash
-python bin/check_zombie_prs.py --repos the-nexus --report
-```
-
-## Conclusion
-
-This implementation provides comprehensive protection against rubber-stamping:
-1. **Automated CI checks** block zombie PRs
-2. **Updated PR template** guides reviewers
-3. **Detection script** identifies existing zombie PRs
-4. **Documentation** explains the problem and solution
-
-**Result:** No more rubber-stamping of PRs with no changes.
