Step 2 of the convergence sequence. The Navigator sits over the
CanonicalProductRegulatoryProfile (prefilled from company-profile / ProductWizard)
and reports ONLY which facts are still missing + prioritized questions to collect
them. It decides which facts are needed, NEVER what applies — that stays with the
Scope Engine (step 3). No regulation logic, no UI, no Go, no RAG.
- NavigatorQuestion (interaction type, NOT a compliance-meta-model class — freeze
v1.0 untouched): question_id, target_field, label, why_needed,
regulatory_domains_unblocked (static metadata), answer_type, options, priority.
- QUESTION_CATALOG: 12 questions over canonical gaps — P0 (markets, role,
lifecycle, machine/component), P1 (radio, usage-data, security-function,
environmental wastewater/air/chemicals triggers), P2 (structured BOM).
- engine: navigate() -> missing_facts + suggested_questions (priority-sorted) +
completeness_summary (ready_for_scope = no P0 missing); apply_answers() ->
updated profile. Pure field-presence; no scope import.
- 8 tests: <=10 questions for a filled company-profile, known facts not re-asked,
environmental = trigger questions only (no law evaluation), apply round-trip,
P0 ordering, ready_for_scope. 41 tests green, mypy clean, LOC ok.
