+### Rule 16: Koby Configuration (DeepSeek-primary)
+(Ref: See Rule 10 for default model behavior, with Koby exception)
+
+Koby uses a split-model architecture:
+
+- Primary Model: `deepseek-v4-flash` via `api.deepseek.com` (for reasoning)
+- Auxiliary Models: `gpu-light` (vision/web_extract) and `syslog-auto` (compression)
+- Key Hygiene: `api_key_env` is strictly `LITELLM_API_KEY` or `DEEPSEEK_API_KEY`
+- Constraint: Do NOT touch Koby's primary model/provider/compression settings unless explicitly ruled by the captain.
