One contract example (Mission #3's public tender) is not enough to safely generalise: it risks baking tender-shaped assumptions into the later Scope→Journey selector. This mission runs TWO deliberately different contract sub-types against the same company through the IDENTICAL engine: - public tender (procurement: pentest report, references, support SLA, SBOM) -> delta 4 - private OEM spec (Lastenheft: CSMS, functional safety, SUMS, ASPICE) -> delta 3 The two deltas are completely DISJOINT (no shared missing capability), proving the contracts are genuinely different — yet there is no per-contract code: assess_transition treats each as a plain Required set, exactly like a regulation or a certification. Evidence-Relevance is target-relative even between two contracts (TISAX worth more to the automotive OEM than to the generic tender). Conclusion: "Contract" as a requirement source is now covered by >=2 diverse cases, so the later selector can treat any contract uniformly. Synthetic company + synthetic contracts (NO real names). Non-runtime -> no deploy. 5 tests pass.
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.
