Abiba fd3c2a575a feat: 2-layer architecture foundation + agent migration
Router v2:
- Atomic GPU slot booking (Redis Lua — closes TOCTOU race)
- Circuit breaker with failure threshold (3 failures/120s → 60s cooldown)
- GPU health scoring with configurable weights (VRAM 40% + temp 30% + load 30%)
- X-Usage-Tokens header for LiteLLM spend tracking
- /health/unified endpoint (aggregates all layers)
- Strict explicit model passthrough (no silent fallback)
- syslog-auto → auto routing fix

Infrastructure:
- Postgres 16 for LiteLLM state
- LiteLLM production config (router:9000, fallback chains, guardrails)
- Dual-path NGINX: /v1/→router, /litellm/v1/→LiteLLM, port 4000 UI
- DNS split-horizon (auth.sysloggh.net → 192.168.68.11)
- 6 LiteLLM virtual keys for agent cutover

Deployed to CT 116, all 6 containers healthy.

Abiba ad9881f141 feat(dashboard): live GPU health scoring + real KPIs
- Added /metrics/gpu-health endpoint with live health scores (VRAM 40%, temp 30%, load 30%)
- Added /metrics/latency endpoint for dashboard KPIs
- Added GPU_LABELS for human-readable model names
- Dashboard v2: rewired to real data endpoints
  - KPI cards: GPUs online, circuit trips, avg latency, req/min, active requests
  - Health scores from actual gpu_health_score() function
  - Rolling 60-sample history chart (real data, no simulation)
  - Status: green/yellow/red based on tripped circuits
  - No CDN dependency (pure CSS)
  - Auto-refresh every 15s
- nginx: /dashboard/ serves static files with cache headers
- docker-compose: dashboard volume mount

Abiba b79af634d7 feat(router): Phase 1 - Actual Circuit Breaker for GPU hosts
- Added is_circuit_tripped(), trip_circuit(), half_open_probe() functions
- Filters out models with tripped circuits in route() function
- Trips circuit on 502/504 errors and timeouts in chat() function
- Prevents hung GPU cascades (Node #480 scenario)

AbibaandAbiba via Kwame 0cb4597b0e security: move API keys to env var, strip from source code fallback
- Added API_KEYS env var to router service in docker-compose.yml
- Replaced hardcoded agent keys in router.py fallback with dev-only placeholder
- Production now loads keys from environment, not source code
- Resolves the final remaining item from CT116 security deep-dive

Abiba 41939104c7 fix: non-blocking GPU health checks + 256K turboquant context upgrade
router/router.py:
- check_gpu_health() now accepts configurable timeouts (sidecar_timeout, gpu_timeout)
- /health and /v1/models endpoints use fast 1.5s/1s timeouts (non-blocking)
- /v1/models now calls check_gpu_health once per model instead of twice
- GPU_CONTEXT updated to 262144 across all models (turboquant upgrade)
- 27B max_concurrent reduced 2→1 (24GB VRAM saturated at 256K context)

docker-compose.yml:
- Router healthcheck timeout 5s→15s, interval 15s→30s
- Nginx healthcheck timeout 5s→15s, interval 15s→30s

Fixes dashboard hang when any GPU is unreachable.

- Router counter leak fix (gpu_decr in except handler)
- VLM slot upgrade 1→2
- Automated maintenance cron job
- LiteLLM config update
