Third instance of the identity-machine pattern (after Master Controls and Master Obligations). New compliance/capability/ package: MasterCapability with stable MCAP ids, CapabilityCandidate minting, seven typed relation types, a VERSIONED derivation policy, and identity lifecycle (merge/split/deprecate/redirect with provenance). Stored: identities, sources, relationship types, policy versions, lifecycle events, provenance. Derived (never stored): confidence/status via evaluate_relation under a policy version. Hard rule (structurally guarded): a certification alone can never yield CONFIRMED — only CONFIRMS + concrete artifact (or expert) does. Built from the Reasoning session per user directive but this IS the Compliance Execution model (Execution owns Capability) — handed off via the board. Metadata-first: CapabilityRelation is registry metadata, NOT a new meta-model class (freeze v1.0 untouched). No Company-Gap, no real ISO/cert mappings, no UI/RAG, no generic canonicalization engine. 11 tests; mypy --strict clean; LOC ok. 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

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.
