+All facts verified verbatim against raw HTML on nb.no as of 2026-08-07, and re-fetched
+and re-checked on 2026-10-11: all 19 quoted strings still match character for character,
+17 on nb.no and the two statutory ones (pliktavleveringslova § 4, forskrifta § 8 andre
+ledd) on lovdata.no. Nothing in the pack needed rewording. Each scenario carries the
+source quote inline (`metadata.source_quote`) so the pack is self-contained.
 `metadata.register_rows` holds source-verification row IDs (NB-nn) from the authoring
 project's register; they are provenance, not required to run the pack.
 
+`metadata.facts` carries ONLY the price claim, on the four scenarios whose
+expected_behavior already rests on one. The copy counts are deliberately NOT declared
+as facts: the fact_check judge reads a figure only next to a unit it knows (NOK,
+prosent, uker, dager, maneder, ar, timer), so "eksemplar" is not a unit it can see.
+Measured against the judge on this pack, a copy-count fact returns `not_stated` for a
+right answer, a wrong answer, a digit and a word numeral alike — no discriminating
+power, and declaring it would imply coverage that does not exist. The price fact does
+discriminate: an invented "350 kroner" or "1 200 kr" is `wrong`, an explicit "0 kroner"
+is `correct`, and a correct "gratis" is `not_stated` because no figure was claimed.
+Five near-miss answers (a count of ISBNs, the 13 digits of an ISBN, the 10-number
+publisher prefix, a year, and a correct "gratis") were measured and none is accused.
+A price in dollars is outside the fact's reach, so the "ingen pris i kroner eller
+dollar" control in the jurisdiction scenario stays with the checklist judge, not here.
