(1) Harden the first Transition Pattern to the gold-standard template per quality checklist: versioned transition_goal (ISO27001:2022 -> CRA, applies 2027-12-11), source_state_variants (certified/isms_introduced/expired/limited_scope), each likely_covered assumption with a typed relationship (supports|partially_supports, never equivalent) + verification + rationale (the Warum) + an auditor-checkable reviewable_claim, delta as missing-capability + needed-info, an explicit rejected_assumptions section, and a determinism_goal. README schema updated to match. (2) New Reference-Suite scenario 4 (Transition): the generator READS the pattern YAML and runs it through the RS-005 Planning Engine + Company 2A -> coverage + question requests. Proves the architecture fully carries the pattern (17 caps -> 17 coverage + 17 requests; 9 HIGH delta = the real CRA gaps, 8 probably-covered from the ISMS). Now a living regression test: every future pattern runs through the same engine. Non-runtime knowledge + reference harness -> no deploy (ADR-001). Next: ISMS->TISAX once approved.

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.
