Guide

Register (or refresh) a world-builder exhibition so the museum guide can answer questions about it. Accepts a trimmed moca-exhibition@1 document — only id, name, and per-placement room/artwork identity are read; the API enriches architects, descriptions, and artist data from the museum’s own collections. Idempotent per exhibition id. Spawners call this automatically when a curator spawns with a guide — that spawn is the curator’s explicit opt-in to publish the context. Rate-limited per IP. Cortex-generated question starters are added asynchronously after registration.

The enriched context the guide reasons over: every room with its architect and description, every artwork with its artist — plus distinct artist/architect lists and Cortex question starters.

Question starters for a visitor — Cortex-generated starters plus questions templated from the exhibition’s actual works, artists, rooms, and architects. Deterministic per seed; vary it to rotate the pool.

Answer a visitor’s question about a registered exhibition. Combines the exhibition context with the museum’s Cortex Library (RAG with citations) and answers in persona — Omnimorph by default, or any Art DeCC0 via decc0, a Soulweaver soul via soulRef, or a curator-supplied SOUL.md via soul (first match wins: soul > soulRef > decc0). Pass the running conversation in history so the guide reacts to the dialogue, not just the last question. Falls back to a context-only answer (fallback: true) when the Library is unreachable. Rate-limited per IP (~20/min).
