Drei zusammenhaengende Stufen 'Cookie-Verhalten ist anders als deklariert' — analog zum VW-Diesel-Skandal-Pattern (Pruefstand vs Realbetrieb). P103 (Stufe 3) — cookie_value_entropy.py: Klassifiziert Cookie-Werte als flag/short_id/long_token/uuid/hash/json_blob via Shannon-Entropy + Regex-Patterns. Wenn ein als 'essential' deklarierter Cookie einen 64-char-Base64-Wert hat → MEDIUM-Finding 'Defeat-Device-Heuristik'. P104 (Stufe 4) — cookie_network_tracer.py: Vergleicht Cookie-Domain mit Site-Hauptdomain + bekannten Tracker-Vendoren (50 Domains gemapped: doubleclick.net, facebook.com, demdex.net, omtrdc.net, adsrvr.org, hotjar.com, ...). Wenn ein als 'essential' deklariertes Cookie von externer Tracker-Domain gesetzt wird → HIGH. Drittland-Cookies werden als 'DRITTLAND US/CN/...' markiert (Schrems-II-Folge). P105 (Stufe 5) — tcf_vendor_authority.py: Ingest-Endpoint POST /api/compliance/agent/admin/tcf-ingest holt die IAB TCF v2 Global Vendor List (vendor-list.consensu.org/v3) und upserted sie in cookie_library mit source='iab_tcf_v2'. cross_reference_with_tcf fuzzy-matched cmp_vendors gegen die TCF-Liste — wenn Vendor in TCF als Marketing gefuehrt aber Site sagt 'Funktional' → HIGH (externe Authority widerspricht der Deklaration). Alle drei rendern eigene Mail-Bloecke im Bereich Cookies (nach cookie_audit_html, vor library_mismatch_html). Co-Authored-By: Claude Opus 4.7 (1M context) <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.
