// TDD for RX-REG (review 2026-07-09, B2/B3/B4/B5 + R3-5/M10): the EU AI Act
// deadlines get ONE machine-readable source — scripts/kb-update/data/ai-act-deadlines.json
// — and every consumer is sync-tested against it:
//   - CLAUDE.md «Viktige frister»-tabellen (date + label + status verbatim)
//   - agents/ai-act-assessor.md frist-malen (identical DATE SET; labels are
//     template-compact by design — R3-5: the 2026-12-02 row was missing)
//   - hooks/scripts/{session-start-context,stop-assessment-reminder}.mjs must READ
//     the source instead of carrying hardcoded date literals (B5: the stop hook
//     labelled 2026-08-02 «GPAI-frist» — wrong article; GPAI was 2025-08-02)
// Refuted-claim guard: the final Omnibus text (EP 2026-06-16, Council 2026-06-29)
// dropped the acceleration trigger, so «kan fremskynde»/«ytre grense» must not
// appear; Nkom is the designated coordinating authority, so «under etablering»
// must be gone (source: nkom.no/ki/regulering/hvem-handhever).
