+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 |

+## 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 |

+
+### 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)
