+// TDD for RX-REG-KB (kryssmodell-review 2026-07-09, replan §RX-REG-KB): the
+// governance reference corpus carried EU AI Act errors that ground-truth
+// verification (EUR-Lex CELEX:32024R1689, AI Act Explorer, regjeringen.no)
+// confirmed as factually wrong. This lint is the *preventive mechanism*
+// (gap-disiplin): once the surgical fixes land, these literals must never
+// re-enter the corpus.
+//
+// Ground truth locked this session:
+//   - Art. 5(1) letters: (c) social scoring is NOT public-authority-limited;
+//     (d) crime-risk prediction by profiling; (e) untargeted facial-image
+//     scraping; (h) real-time RBI for law enforcement. The old table
+//     scrambled (c)/(d)/(e)/(h) and omitted scraping. (EUR-Lex art. 5(1).)
+//   - Art. 6(2): Annex III = high-risk MAIN RULE; Art. 6(3): narrow 4-condition
+//     exception; profiling ⇒ ALWAYS high-risk. The old decision tree inverted
+//     this (profiling as the sole trigger). (EUR-Lex art. 6(2)-(3).)
+//   - Art. 99 fines: (3) €35M/7 %; (4) incl. Art. 50 transparency (4)(g) €15M/3 %;
+//     (5) incorrect info €7,5M/1 %; (6) SMEs = «whichever is LOWER», NO separate
+//     reduced amounts. The old table put transparency at 7,5M/1,5 %, false-info
+//     at 1,5 %, and fabricated an SMB column. (EUR-Lex art. 99(3)-(6).)
+//   - Art. 49 registration timing = before placing on market / putting into
+//     service — NOT a fixed «fra august 2026». High-risk applicability deferred
+//     to 2027-12-02 (Annex III) / 2028-08-02 (Annex I) via Digital Omnibus.
+//   - Bokføringsloven § 13: 5 år (not «7 år»).
+//   - Nkom is the DESIGNATED coordinating market-surveillance authority
+//     (regjeringen besluttet) — «under etablering» is stale.
+//   - Digital Omnibus dropped any acceleration trigger → «fremskynde» must go.
