Code provenance
- All code in private GitHub repos (organisation: aep3065-cyber).
- Pre-commit hook scans for secret leaks (file-level
# FAKEallowlist for test fixtures). - Auto-commit pipeline runs every 2 minutes for canonical state.
- Every code-deployment to canonical paths requires Council pre-flight (multi-agent AI consensus + human sign-off).
AI pipeline
PowerQuant uses a multi-model review pipeline with HARD-KILL gates on uncited legal claims (Senior EU Legal Counsel agent), 4-method evidence-audit consensus (Evidence-audit agent), schema integrity (Integrator agent), strategic alignment (Strategist agent), cost gates (Cost-governance agent), and operational fraud detection (Fraud-officer agent). Heterogeneous model failover: Anthropic → Gemini → Groq → OpenAI. Review votes are signed Ed25519 and chained with prev-hash for tamper-evidence.
Geography
PowerQuant ApS is registered in Copenhagen, Denmark. Founder + Technical Officer based in Denmark. Customer-data processing happens entirely in EU infrastructure (Hetzner DE + Supabase EU + Cloudflare EU edge). LLM inference goes to US-hosted endpoints; sub-processor DPAs (linked at /trust/sub-processors) cover GDPR-compliant international transfers via Standard Contractual Clauses (Module 2).
