Module evaluate 

Turn the support arithmetic into a verdict, and resolve provenance citations into the facts the arithmetic needs.

Functions

evaluate_grounding

Grounding score for claim against the resolved cited facts, as a verdict under thresholds. Empty evidence ⇒ Ungrounded(0.0) (fail closed).

evaluate_output_grounding

End-to-end gate input: resolve the citations and grade the claim in one call. If no citation resolves (no evidence available), returns Ungrounded(0.0) — fail closed.

grounding_verdict

Partition a raw grounding score into a verdict.

resolve_citations

Resolve a slice of provenance citation hashes to their fact quins via resolver, dropping any that do not resolve. The output is what evaluate_grounding consumes.
