Module eval 

Evaluation metrics (DESIGN §14.2). Pure functions comparing extracted assertions against golden-corpus annotations.

Structs

EvalMetrics

Quality metrics computed from an extraction run against golden annotations.

ExtractedTriple

A triple extracted from the brain, for comparison against golden annotations.

Functions

compute_metrics

Compute metrics by comparing extracted triples against expected triples.

compute_metrics_with_fabrication

Like compute_metrics but with a measured fabrication rate (§17.3, 10.7). The fabricated rate is computed separately by measure_fabrication_rate because it requires the source text, which compute_metrics does not take.

measure_fabrication_rate

Measure fabricated entity rate (§17.3, F19, 10.7): of the entity surfaces extracted, what fraction do NOT appear verbatim in the source text? This detects hallucinated entities that slipped past validation.
