 - Free-tier APIs have aggressive rate limits; `sylloge` tracks free-tier quotas separately from paid spend.
 - Deep research can blow $10+ in token costs per query if orchestrated against Anthropic/OpenAI. Default backend is local logismos.
-- `menos gpu research` mode (Phase 6, in coordination with menos-ops) is exclusive with `menos gpu inference` on the W7900; operator picks.
+- GPU research mode (Phase 6) is mutually exclusive with GPU inference mode on a single-GPU host; the operator picks which one holds the device.
 - Downstream use must comply with the scoped license map above; commercial client-contract work must not depend on zetesis.
