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.

backend-compliance
Python/FastAPI service implementing the DSGVO compliance API: DSR, DSFA, consent, controls, risks, evidence, audit, vendor management, ISMS, change requests, document generation.
Port: 8002 (container: bp-compliance-backend)
Stack: Python 3.12, FastAPI, SQLAlchemy 2.x, Alembic, Keycloak auth.
Architecture
compliance/
├── api/ # Routers (thin, ≤30 LOC per handler)
├── services/ # Business logic
├── repositories/ # DB access
├── domain/ # Value objects, domain errors
├── schemas/ # Pydantic models, split per domain
└── db/models/ # SQLAlchemy ORM, one module per aggregate
The service follows this layered target structure but not all files are fully refactored yet. Phase 1 backlog is tracked in .claude/rules/loc-exceptions.txt (27 backend-compliance files currently excepted).
See ../AGENTS.python.md for the full convention and ../.claude/rules/architecture.md for the non-negotiable rules.

Public API surface
404+ endpoints across /api/v1/*. Grouped by domain: ai, audit, consent, dsfa, dsr, gdpr, vendor, evidence, change-requests, generation, projects, company-profile, isms. Every path is a contract — see the "Public endpoints" rule in the root CLAUDE.md.
