Benjamin Admin c908fcd5eb feat(b19): Cookie-Coherence — 3-Layer-Lookup + Vendor-Karten + CSV
Adressiert das BMW-Beispiel (740 Cookies, Salesforce als "essential"
mit 1-Jahres-Lifetime, Pseudo-Zwecke wie "Siehe dazugehörige
Datenverarbeitung"). User-Konzept "Regulation als Code".

Step 1 — cookie_library_lookup.py (3 Layer):
  1. Override = cookie_knowledge_db.py + extended (74) für
     Schrems-II / EUGH / EU-Alternative — BreakPilot-juristische-IP.
  2. Truth-Base = compliance.cookie_library (2287 aus Open Cookie
     Database, CC0). actual_category als Wahrheit.
  3. Auto-Learning = cookie_behavior_audits — Cross-Site-Konsens
     wenn ≥3 Sites denselben Cookie melden.

  Match: exact > prefix (mit Separator-Check) > wildcard. Kurze
  Library-Namen ("c", "ID") brauchen exact-match — verhindert
  False-Positive auf "completely_unknown". Trailing-Underscore
  in OCD ("guest_uuid_essential_") wird als implicit-wildcard
  interpretiert.

Step 2 — cookie_coherence_check.py (B19, 6 Finding-Typen):
  - MARKETING_AS_ESSENTIAL (HIGH): KB sagt actual=marketing, Site
    deklariert essential/erforderlich → Einwilligung wird umgangen
  - LIFETIME_TOO_LONG_FOR_ESSENTIAL (MED): essential + >90d
  - PSEUDO_PURPOSE (LOW): "Siehe dazugehörige Datenverarbeitung"
    / <4 Wörter (suppressed wenn Vendor-Purpose substantial ist)
  - MISSING_COUNTRY (LOW): vendor_country leer trotz KB-Hit
  - UNKNOWN_VENDOR (LOW): nicht in KB → Auto-Learning-Kandidat
  - DUPLICATE_VENDOR (MED): selber Vendor in N Kategorien =
    Stack-Aufspaltung um Marketing unter "essential" zu schmuggeln

  Jedes Finding mit recommended_action ("Cookie X aus 'erforderlich'
  raus und in 'Marketing' setzen").

Step 3 — cookie_observation_logger.py:
  Loggt nach jedem Audit alle (cookie, site, declared_purpose) in
  compliance.cookie_behavior_audits → Basis für Cross-Site-Konsens
  in Layer 3.

Step 4 — cookie_csv_exporter.py:
  cookies-full-{check_id}.csv mit 21 Spalten (Name, Vendor decl/KB,
  Cat decl/KB, Lifetime decl/KB, Country, Opt-Out, 8x FIND_* flags,
  recommended_action). UTF-8 BOM für Excel.
  ZIP-Attachment: erweitert audit_walk_zip_builder um extra_files=
  parameter; phase_e ruft mit cookies-full-...csv auf.

Step 5 — mail_render_v2/_vendor_cards.py:
  Statt 740 Cookie-Rows: Aggregation pro Vendor mit Cookie-Count +
  Issue-Count + 1-2 Beispiel-Cookies + Issue-Type-Tags. Top 30
  Vendoren in der Mail, Rest nur in CSV. Sortiert nach Issue-Score.

Step 6 — render_info_box_rechtsrahmen():
  Generic Header-Info-Box mit Art. 13 DSGVO + § 25 TDDDG + Art. 5
  + § 5 UWG + § 30/130 OWiG. Immer angezeigt, kein explicit-
  finding-mapping (User-mündigkeit).

Orchestrator + _compose: run_b19 + render_vendor_cards +
  render_info_box_rechtsrahmen ins V2-Layout.

Tests: 28/28 grün (15 lookup + 13 coherence).

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.

Run locally

cd backend-compliance
pip install -r requirements.txt
export COMPLIANCE_DATABASE_URL=...  # Postgres (Hetzner or local)
uvicorn main:app --reload --port 8002

Tests

pytest compliance/tests/ -v
pytest --cov=compliance --cov-report=term-missing

Layout: tests/unit/, tests/integration/, tests/contracts/. Contract tests diff /openapi.json against tests/contracts/openapi.baseline.json.

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.
