- Saturated flag now triggers on load saturation (was dead code) - Heavy tier routes MoE(131K) first instead of Dense(98K) - Token estimation uses JSON length/3.5 (was content/4) - Cross-turn session tracking via X-Session-Id + Redis TTL 24h
syslog-harness — Inference API Harness
CT 116 Docker stack for routing local GPU models through a unified OpenAI-compatible API.

Authentication
All /v1/chat/completions requests require a valid API key via Authorization: Bearer <key>. Missing or invalid keys return 401 Unauthorized.
Agent API Keys
| Agent | Key |
|---|---|
| Abiba | sk-syslog-abiba |
| Mumuni | sk-syslog-mumuni |
| Tanko | sk-syslog-tanko |
| Koby | sk-syslog-koby |
| Kagenz0 | sk-syslog-kagenz0 |
| Koonimo | sk-syslog-koonimo |
Routing Tiers
| Tier | Trigger | Priority |
|---|---|---|
| Lightweight | No system prompt, ≤1 turn, ≤100 words | VLM → MoE → Dense |
| Simple Conv | ≤1000 tokens, ≤4 turns | VLM → MoE → Dense |
| Heavy | >4000 tokens OR >8 turns | Dense → MoE → VLM |
| Default | Everything else | MoE → VLM → Dense |
Queue
When all GPUs are saturated, requests enter a polling queue (500ms intervals) instead of returning 503 immediately. Timeout: 30s (configurable via QUEUE_TIMEOUT env or X-Queue-Timeout header).
Models
