🟢basis_answer(query, session_id)

Ask the Basis Agent a question about attested risk state. Answers come ONLY from attested substrate state, cited to attestation hashes; queries the substrate cannot ground are refused (identical envelope, refusals, and receipts as the REST transport — the agent never recommends positions, never forecasts, never executes). Every call is logged as an attributed protocol read. Identity: pass your hub API key on the /mcp HTTP request (``x-api-key`` header or ``?apikey=`` query param) so reads are attributed to your service; keyless calls are attributed by IP. Multi-turn: the returned envelope carries ``session_id`` — pass it back as the ``session_id`` argument on your next call to hold a session (follow-ups like "and its liquidity?" then inherit the session's entity). An ``X-Basis-Session`` header on the /mcp request works too; the explicit argument wins. Omit both and each call is a fresh single-turn session. Parameters: query: The question (max 4000 chars). session_id: Session UUID from a previous basis_answer envelope (optional — enables multi-turn follow-ups).
