Second reasoning mode, scope per user: the engine owns the INFORMATION GAPS, not the
questions. assess_transition(context, target_requirements, company_profile) emits
ranked TransitionQuestionRequest {capability, control, reason, question_intent,
expected_evidence, priority, information_gain} -- NOT rendered question text. Rendering
(intent+subject->sentence) is a separate swappable layer (RS-005.1), not here.
Consumes the Company Capability Profile (2A) as "have" + injected TargetRequirement
(Execution-owned placeholder) as "required" -- no required-capability data in product
code (EMPTY_REQUIREMENTS, mocks only in tests). A certification-derived capability is
probably_covered (Welt 1) -> a confirmation request, never already_covered/"erfuellt".
Deterministic, computed-not-stored, no percentages.
Activates 2A/2C/RCI (first consumer of the Company profile). Freeze-respecting: additive
package, no new graph/base class/meta-model class. 9 tests, mypy --strict clean, LOC ok.
No endpoint/UI/RAG; question rendering deliberately deferred to RS-005.1.

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.
