Extends CompliancePDFGenerator with a "Quellen & Lizenzen" section
appended to every generated compliance PDF.
The footer is built from compliance.canonical_controls + control_parent_links
directly (no HTTP hop to /licenses/aggregate — same DB connection
already open in the generator). It groups by license_rule and lists
the top 8 source regulations per bucket.
For Rule-2 entries (CC-BY-SA, OECD-Public, Apache, etc.) it emits the
mandatory attribution paragraph required by the underlying licenses.
For Rule 1 a brief reference list satisfies the auditability goal
without legal obligation. Rule 3 is identifier-only by design.
Architecture decision: this is a PLATFORM-level footer (which sources
the platform draws on overall), not a per-export filter of "only the
sources actually cited in THIS document". The latter would require
control-uuid tracking across all sections (TOM/VVT/DSFA/etc.) which
the current PDF generator does not surface — that's a follow-up scope.
The platform-level footer fulfils the immediate legal mandate that
attribution be present on the work, not buried in AGB/Impressum.
Part of Attribution-Renderer Task #23. Stufe 1 (overview page) +
Stufe 3 (SourceBadge component) already shipped in commit dfac940.
Stufe 4 (tech-file appendix) remains for the IACE tech-file generator
in a separate iteration.
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.
