-# Duplicate PR Prevention System
-
-## Problem
-
-Despite having tools to detect and clean up duplicate PRs, agents were still creating duplicate PRs for the same issue. This was incredibly ironic, especially for issue #1128 which was about cleaning up duplicate PRs.
-
-## Solution
-
-We've created a comprehensive system to prevent duplicate PRs:
-
-### 1. Pre-flight Checks
-
-Before creating a PR, agents should run a pre-flight check to see if PRs already exist for the issue.
-
-#### Bash Version
-```bash
-# Check for existing PRs for issue #1128
-./scripts/check-existing-prs.sh 1128
-
-# Exit codes:
-# 0 - No existing PRs found (safe to create new PR)
-# 1 - Existing PRs found (do not create new PR)
-# 2 - Error (API failure, missing parameters, etc.)
-```
-
-#### Python Version
-```bash
-# Check for existing PRs for issue #1128
-python3 scripts/check_existing_prs.py 1128
-
-# Same exit codes as bash version
-```
-
-#### User-Friendly Wrapper
-```bash
-# Get guidance and suggestions
-./scripts/pr-safe.sh 1128
-
-# With suggested branch name
-./scripts/pr-safe.sh 1128 fix/1128-my-fix
-```
-
-### 2. Cleanup Tools
-
-For cleaning up existing duplicate PRs:
-
-```bash
-# Dry run (show what would be done)
-./scripts/cleanup-duplicate-prs.sh --dry-run
-
-# Actually close duplicate PRs
-./scripts/cleanup-duplicate-prs.sh --close
-```
-
-## Workflow Integration
-
-### For Agents
-
-Before creating a PR, agents should:
-
-1. Run the check: `./scripts/check-existing-prs.sh <issue_number>`
-2. If exit code is `0`, proceed with PR creation
-3. If exit code is `1`, review existing PRs instead
-
-### For Humans
-
-Before creating a PR:
-
-1. Run: `./scripts/pr-safe.sh <issue_number>`
-2. Follow the guidance provided
-
-## Prevention Strategy
-
-### 1. Pre-flight Checks
-
-Always run a pre-flight check before creating a PR:
-
-```bash
-# In your agent workflow
-if ./scripts/check-existing-prs.sh $ISSUE_NUMBER; then
-    # Safe to create PR
-    create_pr
-else
-    # Don't create PR, review existing ones
-    review_existing_prs
-fi
-```
-
-### 2. GitHub Actions Integration
-
-The existing `.github/workflows/pr-duplicate-check.yml` workflow can be enhanced to run these checks automatically.
-
-### 3. Agent Instructions
-
-Add to agent instructions:
-
-```
-Before creating a PR for an issue, ALWAYS run:
-  ./scripts/check-existing-prs.sh <issue_number>
-
-If PRs already exist, DO NOT create a new PR.
-Instead, review existing PRs and add comments or merge them.
-```
-
-## Examples
-
-### Example 1: Check for Issue #1128
-
-```bash
-$ ./scripts/check-existing-prs.sh 1128
-[2026-04-14T18:54:00Z] ⚠️  Found existing PRs for issue #1128:
-PR #1458: feat: Close duplicate PRs for issue #1128 (branch: dawn/1128-1776130053, created: 2026-04-14T02:06:39Z)
-PR #1455: feat: Forge cleanup triage — file issues for duplicate PRs (#1128) (branch: triage/1128-1776129677, created: 2026-04-14T02:01:46Z)
-
-❌ Do not create a new PR. Review existing PRs first.
-```
-
-### Example 2: Safe to Create PR
-
-```bash
-$ ./scripts/check-existing-prs.sh 9999
-[2026-04-14T18:54:00Z] ✅ No existing PRs found for issue #9999
-Safe to create a new PR
-```
-
-## Related Issues
-
-- Issue #1474: [META] Still creating duplicate PRs for issue #1128 despite cleanup
-- Issue #1460: [META] I keep creating duplicate PRs for issue #1128
-- Issue #1128: [RESOLVED] Forge Cleanup — PRs Closed, Milestones Deduplicated, Policy Issues Filed
-
-## Lessons Learned
-
-1. **Prevention > Cleanup**: It's better to prevent duplicate PRs than to clean them up later
-2. **Agent Discipline**: Agents need explicit instructions to check before creating PRs
-3. **Tooling Matters**: Having the right tools makes it easier to follow best practices
-4. **Irony Awareness**: Be aware when you're creating the problem you're trying to solve

+# 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.

+# Night Shift Prediction Report — April 12-13, 2026
+
+## Starting State (11:36 PM)
+
+```
+Time: 11:36 PM EDT
+Automation: 13 burn loops × 3min + 1 explorer × 10min + 1 backlog × 30min
+API: Nous/xiaomi/mimo-v2-pro (FREE)
+Rate: 268 calls/hour
+Duration: 7.5 hours until 7 AM
+Total expected API calls: ~2,010
+```
+
+## Burn Loops Active (13 @ every 3 min)
+
+| Loop | Repo | Focus |
+|------|------|-------|
+| Testament Burn | the-nexus | MUD bridge + paper |
+| Foundation Burn | all repos | Gitea issues |
+| beacon-sprint | the-nexus | paper iterations |
+| timmy-home sprint | timmy-home | 226 issues |
+| Beacon sprint | the-beacon | game issues |
+| timmy-config sprint | timmy-config | config issues |
+| the-door burn | the-door | crisis front door |
+| the-testament burn | the-testament | book |
+| the-nexus burn | the-nexus | 3D world + MUD |
+| fleet-ops burn | fleet-ops | sovereign fleet |
+| timmy-academy burn | timmy-academy | academy |
+| turboquant burn | turboquant | KV-cache compression |
+| wolf burn | wolf | model evaluation |
+
+## Expected Outcomes by 7 AM
+
+### API Calls
+- Total calls: ~2,010
+- Successful completions: ~1,400 (70%)
+- API errors (rate limit, timeout): ~400 (20%)
+- Iteration limits hit: ~210 (10%)
+
+### Commits
+- Total commits pushed: ~800-1,200
+- Average per loop: ~60-90 commits
+- Unique branches created: ~300-400
+
+### Pull Requests
+- Total PRs created: ~150-250
+- Average per loop: ~12-19 PRs
+
+### Issues Filed
+- New issues created (QA, explorer): ~20-40
+- Issues closed by PRs: ~50-100
+
+### Code Written
+- Estimated lines added: ~50,000-100,000
+- Estimated files created/modified: ~2,000-3,000
+
+### Paper Progress
+- Research paper iterations: ~150 cycles
+- Expected paper word count growth: ~5,000-10,000 words
+- New experiment results: 2-4 additional experiments
+- BibTeX citations: 10-20 verified citations
+
+### MUD Bridge
+- Bridge file: 2,875 → ~5,000+ lines
+- New game systems: 5-10 (combat tested, economy, social graph, leaderboard)
+- QA cycles: 15-30 exploration sessions
+- Critical bugs found: 3-5
+- Critical bugs fixed: 2-3
+
+### Repository Activity (per repo)
+| Repo | Expected PRs | Expected Commits |
+|------|-------------|-----------------|
+| the-nexus | 30-50 | 200-300 |
+| the-beacon | 20-30 | 150-200 |
+| timmy-config | 15-25 | 100-150 |
+| the-testament | 10-20 | 80-120 |
+| the-door | 5-10 | 40-60 |
+| timmy-home | 10-20 | 80-120 |
+| fleet-ops | 5-10 | 40-60 |
+| timmy-academy | 5-10 | 40-60 |
+| turboquant | 3-5 | 20-30 |
+| wolf | 3-5 | 20-30 |
+
+### Dream Cycle
+- 5 dreams generated (11:30 PM, 1 AM, 2:30 AM, 4 AM, 5:30 AM)
+- 1 reflection (10 PM)
+- 1 timmy-dreams (5:30 AM)
+- Total dream output: ~5,000-8,000 words of creative writing
+
+### Explorer (every 10 min)
+- ~45 exploration cycles
+- Bugs found: 15-25
+- Issues filed: 15-25
+
+### Risk Factors
+- API rate limiting: Possible after 500+ consecutive calls
+- Large file patch failures: Bridge file too large for agents
+- Branch conflicts: Multiple agents on same repo
+- Iteration limits: 5-iteration agents can't push
+- 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)
