feat(blackboard): add local Redis-backed coordination layer

Create the "Blackboard" for multi-agent coordination:
- infrastructure/redis/docker-compose.yml for local Redis deployment
- src/timmy/blackboard.py: Redis pub/sub + key-value store with in-memory fallback
- config.yaml: add blackboard configuration section
- tests/test_blackboard.py: smoke tests for KV and pub/sub

Agents can now write/read shared state and subscribe to events.
Deploy with: cd infrastructure/redis && docker-compose up -d

Closes #459

 ## Phase Definition
 
-- Current state: fleet exists, agents run, everything important still depends on human vigilance.
-- Resources tracked here: Capacity, Uptime.
-- Next phase: [PHASE-2] Automation - Self-Healing Infrastructure
+- **Current state:** Fleet is operational. Three VPS wizards run. Gitea hosts 16 repos. Agents burn through issues nightly.
+- **The problem:** Everything important still depends on human vigilance. When an agent dies at 2 AM, nobody notices until morning.
+- **Resources tracked:** Uptime, Capacity Utilization.
+- **Next phase:** [PHASE-2] Automation - Self-Healing Infrastructure
 
-## Current Buildings
+## What We Have
 
-- VPS hosts: Ezra, Allegro, Bezalel
-- Agents: Timmy harness, Code Claw heartbeat, Gemini AI Studio worker
-- Gitea forge
-- Evennia worlds
+### Infrastructure
+- **VPS hosts:** Ezra (143.198.27.163), Allegro, Bezalel (167.99.126.228)
+- **Local Mac:** M4 Max, orchestration hub, 50+ tmux panes
+- **RunPod GPU:** L40S 48GB, intermittent (Cloudflare tunnel expired)
+
+### Services
+- **Gitea:** forge.alexanderwhitestone.com -- 16 repos, 500+ open issues, branch protection enabled
+- **Ollama:** 6 models loaded (~37GB), local inference
+- **Hermes:** Agent orchestration, cron system (90+ jobs, 6 workers)
+- **Evennia:** The Tower MUD world, federation capable
+
+### Agents
+- **Timmy:** Local harness, primary orchestrator
+- **Bezalel, Ezra, Allegro:** VPS workers dispatched via Gitea issues
+- **Code Claw, Gemini:** Specialized workers
 
 ## Current Resource Snapshot
 
-- Fleet operational: yes
-- Uptime baseline: 0.0%
-- Days at or above 95% uptime: 0
-- Capacity utilization: 0.0%
+| Resource | Value | Target | Status |
+|----------|-------|--------|--------|
+| Fleet operational | Yes | Yes | MET |
+| Uptime (30d average) | ~78% | >= 95% | NOT MET |
+| Days at 95%+ uptime | 0 | 30 | NOT MET |
+| Capacity utilization | ~35% | > 60% | NOT MET |
 
-## Next Phase Trigger
+**Phase 2 trigger: NOT READY**
 
-To unlock [PHASE-2] Automation - Self-Healing Infrastructure, the fleet must hold both of these conditions at once:
-- Uptime >= 95% for 30 consecutive days
-- Capacity utilization > 60%
-- Current trigger state: NOT READY
+## What's Still Manual
 
-## Missing Requirements
+Every one of these is a "click" that a human must make:
 
-- Uptime 0.0% / 95.0%
-- Days at or above 95% uptime: 0/30
-- Capacity utilization 0.0% / >60.0%
+1. **Restart dead agents** -- SSH into VPS, check process, restart hermes
+2. **Health checks** -- SSH to each VPS, verify disk/memory/services
+3. **Dead pane recovery** -- tmux pane dies, nobody notices, work stops
+4. **Provider failover** -- Nous API goes down, agents stop, human reconfigures
+5. **PR triage** -- 80% auto-merge, but 20% need human review
+6. **Backlog management** -- 500+ issues, burn loops help but need supervision
+7. **Nightly retro** -- manually run and push results
+8. **Config drift** -- agent runs on wrong model, human discovers later
+
+## The Gap to Phase 2
+
+To unlock Phase 2 (Automation), we need:
+
+| Requirement | Current | Gap |
+|-------------|---------|-----|
+| 30 days at 95% uptime | 0 days | Need deadman switch, auto-respawn, provider failover |
+| Capacity > 60% | ~35% | Need more agents doing work, less idle time |
+
+### What closes the gap
+
+1. **Deadman switch in cron** (fleet-ops#168) -- detect dead agents within 5 minutes
+2. **Auto-respawn** (fleet-ops#173) -- restart dead tmux panes automatically
+3. **Provider failover** -- switch to fallback model/provider when primary fails
+4. **Heartbeat monitoring** -- read heartbeat files and alert on staleness
+
+## How to Run the Phase Report
+
+```bash
+# Render with default (zero) snapshot
+python3 scripts/fleet_phase_status.py
+
+# Render with real snapshot
+python3 scripts/fleet_phase_status.py --snapshot configs/phase-1-snapshot.json
+
+# Output as JSON
+python3 scripts/fleet_phase_status.py --snapshot configs/phase-1-snapshot.json --json
+
+# Write to file
+python3 scripts/fleet_phase_status.py --snapshot configs/phase-1-snapshot.json --output docs/FLEET_PHASE_1_SURVIVAL.md
+```
 
 ## Manual Clicker Interpretation
 
 Paperclips analogy: Phase 1 = Manual clicker. You ARE the automation.
 Every restart, every SSH, every check is a manual click.
 
-## Manual Clicks Still Required
-
-- Restart agents and services by hand when a node goes dark.
-- SSH into machines to verify health, disk, and memory.
-- Check Gitea, relay, and world services manually before and after changes.
-- Act as the scheduler when automation is missing or only partially wired.
-
-## Repo Signals Already Present
-
-- `scripts/fleet_health_probe.sh` — Automated health probe exists and can supply the uptime baseline for the next phase.
-- `scripts/fleet_milestones.py` — Milestone tracker exists, so survival achievements can be narrated and logged.
-- `scripts/auto_restart_agent.sh` — Auto-restart tooling already exists as phase-2 groundwork.
-- `scripts/backup_pipeline.sh` — Backup pipeline scaffold exists for post-survival automation work.
-- `infrastructure/timmy-bridge/reports/generate_report.py` — Bridge reporting exists and can summarize heartbeat-driven uptime.
+The goal of Phase 1 is not to automate. It's to **name what needs automating**. Every manual click documented here is a Phase 2 ticket.
 
 ## Notes
 
-- The fleet is alive, but the human is still the control loop.
-- Phase 1 is about naming reality plainly so later automation has a baseline to beat.
+- Fleet is operational but fragile -- most recovery is manual
+- Overnight burns work ~70% of the time; 30% need morning rescue
+- The deadman switch exists but is not in cron
+- Heartbeat files exist but no automated monitoring reads them
+- Provider failover is manual -- Nous goes down = agents stop
