Primary tool for pattern-based operations on TheBrain. Requires npub for credit billing. Accepts BrainQuery (BQL) -- a Cypher subset supporting MATCH, WHERE, CREATE, SET, MERGE, DELETE, and RETURN. ⚠️ Name-based matching (MATCH by name, WHERE CONTAINS/STARTS WITH/=~) resolves through the vendor's search/name index, which is incomplete on large brains (TheBrainTech/thebrain-api-quickstart-python#1): a query may fail to match a thought that provably exists. An empty match set is NOT proof of absence — do not CREATE/MERGE a node on the assumption it is missing without an ID-based check (get_thought). Matching by ID is reliable; matching by name inherits the index's blind spots.
