Read + against the transcripts, 5 of the 12 were real errors and none of them + was flagged. + + The same transcripts with anchors, ordered F1, amount-only units and + whole-number parsing: 1 wrong (a real error), 1 correct, 5 not_stated, + 5 ambiguous. No false accusation, but four of the five real errors were + still ambiguous: a sentence such as "Med G = 130 160 kr blir taket + 780 960 kr" carries two facts' figures, an answer that gives last year's + figure beside this year's has two candidates by construction, and a + figure under a markdown heading ("**Personfradrag**" ... "For 2026 er + det 114 540 kr") is anchored by the heading, not by its own sentence. + + With headings carrying their anchor down, four more anchor phrases taken + from the answers, and the outcome rule above: 6 wrong, 2 correct, 4 + not_stated, 0 ambiguous. All five real errors are wrong. The sixth is + "rundt 37 kr per barn per dag" against 38, hedged and capped at medium. + One of the two correct is "46 %" given after "31,25 %" two turns earlier; + the earlier figure is reported in ``other_values`` and not held against + the answer. + + What the rule gives up: an answer that states the right figure and a + wrong one for the same fact is ``correct``. + + A holdout followed: the same six scenarios run again, each fact labelled + by one reader before the verdicts were opened. Reader and judge agreed + on 10 of 12. The judge found 6 of 7 real errors, missed one behind a + range ("rundt 108 000–115 000 kr" around the declared figure, then "Jeg + tror det er 108 550 kr"), and made one false accusation from the + sentence after an anchor. The fallback to that sentence is gone and a + range is weighed only where there is no point figure. On the holdout + transcripts that gives 12 of 12; on the first run it costs one real + error, whose figure stood in the sentence after its anchor (5 wrong, 2 + correct, 5 not_stated). + + Twelve facts and one reader are not a precision estimate, and both sets + have now been used to change the judge. + +The learned sentence picker described below predates the anchors. It is kept +as an opt-in and is not needed. + +Why a learned picker instead of a regex over the whole answer: a regex does +not know WHO claims a number. An answer that echoes the user's "6 weeks" +before correcting it looks, to a regex, exactly like an answer that states +"6 weeks" as the rule. The head scores each sentence for whether it carries +a claim about the fact; the number is then read deterministically from the +chosen sentences alone. + + HOW WELL THIS WORKS, MEASURED + ----------------------------- + Forseti phase 3 (prereg 208343b2, leave-one-scenario-out over 12 + scenarios, 324 answer/fact pairs) found the head DOES NOT meet its + pre-registered criterion: + + * pair-level precision 0.852, BELOW the regex baseline of 0.867 on the + same 324 pairs + * 12 of 13 known false accusations survive (the criterion allowed 3) + + The sentence-level signal is real (AUROC 0.910; true bearers score a + median 0.879 against 0.008 for ordinary sentences) but the head does not + separate bearers from ECHOES of the user's own figures — "## 6 uker er + lenge" scores 0.991. The distinguishing information lives in the user's + prompt, which the head never sees. + + Therefore this judge is registered with ``default_enabled: False`` and + MUST be opted into explicitly. + +Model loading is an OPTIONAL dependency.
