Pillar B of the fragJulia documentation system — the authoritative internal reference. Eight docs across three priority bands (P0 BfArM filing blockers → P1 onboarding → P2 ops reference).

P0 — BfArM filing blockers

• System Architecture — topology, data flows, PHI/DSGVO/EU residency, fail-open risks
• Audit Logging System — design for audit_logs table (DiGAV §4(3), DSGVO Art. 9 / 5(2) / 15 / 17). Zero audit infra exists today.

P1 — High-value onboarding

• Subscription, Tiers & Feature Gating — free/plus/premium, TIER_FEATURES, client + server enforcement, Stripe
• Configuration System — env var inventory across Vercel web, EC2 voice, EAS mobile
• API Documentation — 17 route domains, auth patterns, tier gating, rate limiting

P2 — Reference

• Streaming (Text Chat) — AI SDK v6 pipeline, onFinish gap, anon→auth chat, Bedrock migration path
• Container System — EC2 voice stack, GPU/VRAM split, health + startup order, ops runbook
• Health Checks — liveness vs readiness, degraded-mode matrix, fail-closed guardrail requirement
