Phase A½. The move from feature to product development: for every assessment, answer "how sure are we that this answer is COMPLETE?" — different from confidence. The product never claims full coverage; it makes its own knowledge state transparent and auditable. Shows what we do NOT know and why. - compliance/completeness/: assess_completeness(identified, corpus_status, uncertain, assumptions, assessed_obligations) -> CompletenessReport. Separates IDENTIFIED from ASSESSED (validated corpus AND determined applicability) and justifies every gap. Two kinds of open: corpus gap (future_corpus) and applicability uncertainty (query_required + deciding question, e.g. Data Act / generates_usage_data). - The metric is COUNTS, never a single percentage: "Identifiziert N · bewertet M · offen K · Unsicherheiten U · Begründung ja" + an honest audit statement. - ADR-007: auditable honesty; phase order A factory -> A½ Completeness -> B new domains; the transparency selling point. Deterministic, no LLM; corpus status + obligation count injected. - reference suite: "Regulatory Completeness" section runs an industrial-dishwasher assessment (assessed CRA/MaschinenVO; open EMV/Environmental=future_corpus, Data Act=query_required) and notes Environmental flips open->validated automatically once the corpus lands. 11 completeness tests (54 with adjacent modules), mypy --strict clean (15 files), check-loc 0. Product code with no app caller + ADR/reference = non-runtime -> no deploy (ADR-001). Freeze-safe. 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
├── 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.
