RCI/Delta as a read-/reasoning layer ON TOP of the product-first pipeline. Answers "what changes relative to my existing Regulatory Map?" — NOT "what does the new law say in general". No UI, no ingestion (newsletter/mailbox), no RAG, no new regulations/controls, no legal evaluation outside the stored map. - 4 core objects (compliance/rci/schemas.py): ComplianceBaseline (snapshot of profile + map + registry obligations + required/present evidence), RegulatoryChange (simulated/provided INPUT), ObligationDelta (delta_type NEW|CHANGED|REMOVED| ALREADY_COVERED|NEEDS_REVIEW|NOT_APPLICABLE), ChangeImpactSummary. delta_type is a THIRD vocabulary, disjoint from ClaimCoverage (Welt 1) and ComplianceStatus (Welt 2). - create_baseline() snapshots the existing pipeline once; assess_change() computes deltas deterministically against the snapshot (no re-evaluation). - 12 tests = the 5 acceptance questions (affects product? new/changed? already covered by evidence? needs human review? not relevant?) + repeal/uncertain-reg/ missing-evidence/boundary. Existing pipeline tests stay green; mypy clean; LOC ok. - App/reasoning types only — no compliance-meta-model classes (freeze v1.0 untouched). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
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.
