Answer a question from the claim graph.

PASS THE QUESTION, NOT KEYWORDS. Phrasing carries meaning the ranking uses: "why is X still pending" is a question about mechanism and wants a durable explanation, while "is X still the current path" is about currency and wants the newest practice. Reduced to "X pending" both look identical and the wrong claims win. Full questions retrieve at least as well here — this is not a keyword index.

Returns claims ranked by epistemic standing — similarity, provenance, currency, and whether a claim superseded others — each with its source, kind, assertion date, and the intent the question was read as.

as_of: ISO date. Answers as the graph stood then ("what did I believe in June?"). intent: override if the reading looks wrong — mechanism | current | historical | neutral.

How belief about a subject changed over time.

Matching claims in assertion order, showing which superseded which. Use when an answer may have changed rather than merely being unknown.

Open contradictions the compiler could not settle. Empty is the normal state.

What the corpus contains: counts by source, kind and trust.
