-# Hermes Agent Capability Expansion — Status Tracker
-
-Epic #1120. Six workstreams transforming Hermes from chatbot to sovereign agent.
-
-## Workstream Status
-
-| # | Capability | Issue | PR | Status |
-|---|-----------|-------|-----|--------|
-| 1 | MCP (Model Context Protocol) | #1121 | #1600 | IN PR (docs) |
-| 2 | A2A (Agent2Agent) | #1122 | — | CLOSED |
-| 3 | Local LLM (llama.cpp) | #1123 | #1586 | IN PR |
-| 4 | Memory (MemPalace) | #1124 | — | Pending |
-| 5 | Computer Use | #1125 | — | Pending |
-| 6 | Voice (TTS) | #1126 | — | Pending |
-
-## Capability Details
-
-### 1. MCP — Model Context Protocol
- **Goal:** Hermes speaks MCP natively — client + server
- **Status:** Documentation complete (PR #1600). Client code exists in `tools/mcp_tool.py`
- **Next:** Server implementation, integration testing
-
-### 2. A2A — Agent2Agent Protocol
- **Goal:** Inter-wizard delegation via standardized protocol
- **Status:** CLOSED — implemented via existing delegate_tool + fleet API
-
-### 3. Local LLM — llama.cpp Backend
- **Goal:** Sovereign, offline inference on local hardware
- **Status:** PR #1586 in progress. Ollama integration exists for some models
- **Next:** Standardize llama.cpp backend, FP8 quantization
-
-### 4. Memory — MemPalace Integration
- **Goal:** Cross-session agent memory with structured knowledge
- **Status:** MemPalace skill exists. Integration with session_search pending
- **Next:** Wire MemPalace into session_search pipeline
-
-### 5. Computer Use — Desktop/Browser Automation
- **Goal:** Claude Computer Use pattern for desktop/browser control
- **Status:** Browser tools exist (tools/browser_tool.py). Desktop automation pending
- **Next:** Screen capture + click automation layer
-
-### 6. Voice — TTS Fallback
- **Goal:** Edge-TTS for alerts and voice memos
- **Status:** TTS tool exists (tools/tts_tool.py). Edge-TTS backend pending
- **Next:** Wire edge-tts as fallback for cloud TTS
-
-## Definition of Done
-
- [ ] All 6 sub-issues closed or descoped with reason
- [ ] At least 3 capabilities live in production (Beta/Alpha)
- [ ] Documentation updated
- [ ] Demo: cross-capability flow recorded
-

-# 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)
