Connects the Navigator's fact-gate to the existing reasoning discover_scope — the Scope Engine decides only once the minimum (P0) facts are released. - resolve_product_scope(canonical): if not ready_for_scope -> NEEDS_FACTS (missing_facts + suggested_questions, discover_scope NOT run); else project canonical->reasoning profile and run the EXISTING discover_scope exactly once -> RESOLVED with applicable/excluded/uncertain regulations. - Environmental triggers surface ONLY as unsupported_domains (future_corpus_needed), never as a legal evaluation — transparency, no false completeness. - POST /reasoning/product-scope (thin handler) returns case NEEDS_FACTS or RESOLVED. - No new scope rules, no new regulations, no environmental-law evaluation, no UI, no Go, no RAG, no percent-compliance. Response types are application-level, not meta-model classes (freeze v1.0 untouched). - 6 tests incl. discover_scope spy (0 calls when gated, exactly 1 when ready), category separation, environmental-as-unsupported-only. 47 tests green (existing reasoning MVP tests stay green), mypy clean, LOC ok.
