Architecture Blueprint
Sovereign Resilient Enterprise PatternFor regulated finance / high-sensitivity workloads: EU-jurisdiction or EUCS-High+ cloud, confidential computing, BYOK via external HSM, multi-region failover, full FCoT/OpenTelemetry tracing, DORA-grade third-party auditing.
Mode 3 — Human-on-the-LoopAutonomous execution with aggregate oversight: dashboards, sampling audits (5–10%), real-time veto. For high-volume, low-individual-impact steps.
Required Technical Components (15)
HITL Escalation Queue & Review UIHITL escalation queue & review UI ('Human-as-a-Tool': the agent calls the human like any other tool via propose-action objects). Confidence- and risk-threshold routing, SLA timers, structured accept/modify/reject verdicts with digital reviewer signature at gate release — each verdict is itself Art. 14 evidence and feeds the active-learning loop.

Bitemporal Memory (GDPR×Art.12)valid_from/valid_to + transaction time on every record: GDPR erasure removes data from the active retrieval path while the HMAC-chained immutable log survives for Art. 12 / PLD defence; tenant-scoped partitions allow physical scrub of PII.

PII Scrubbing / DLP-NER LayerAutomated detection, pseudonymisation and blocking of personal data in inputs, retrievals and outputs.
from: GDPR Art. 25
Per-Tenant Retrieval SegmentationRetrieval is scoped by tenant and by caller entitlement at query time, preventing cross-client and cross-role leakage through shared indexes.
from: GDPR Art. 25
Segmented Vector Store (RBAC + CMEK)Vector indexes, embeddings and document stores are logically and physically partitioned per client, with role-based access and customer-managed encryption keys.
from: GDPR Art. 25
Live Risk Register / Posture ManagementContinuously updated risk register wired to runtime posture: threat-model deltas, open defects, control status, exposure per system. Includes Shadow-AI discovery — continuous scanning for unsanctioned agents, MCP servers and AI API usage outside the register; an unregistered agent is an unmanaged Art. 12/26 liability and the empirical driver of proportionate (not blanket) controls.
from: GDPR Art. 35
Multi-Region Failover & Resilience TestingDORA-grade continuity: regional redundancy, chaos testing, exit strategies for critical third parties.
from: DORA · Sovereign Resilient Enterprise Pattern
Vendor & Model Due-Diligence KitScoring model: jurisdiction (CLOUD Act exposure), zero-data-retention, BYOK support, audit evidence (C5/AIC4/ISO 42001/EN 18286:2026), tenant isolation.

Confidential Computing EnclavesAMD SEV / Intel TDX: data protected from the cloud operator even in memory during inference.
from: Sovereign Resilient Enterprise Pattern
BYOK via External HSMCustomer-controlled key sovereignty; cascaded encryption independent of the cloud provider.
from: Sovereign Resilient Enterprise Pattern
OpenTelemetry / FCoT TracingHierarchical trace spans for every sub-task, prompt, retrieved document and API call — the reconstructible decision path for Art. 12/14 and PLD disclosure.
from: Sovereign Resilient Enterprise Pattern
Sovereign Context LayerGoverned runtime workspace operationalizing Art. 10: traceable lineage for every RAG chunk and training record at execution time, canonical version-controlled business glossary (documents Art. 10(2)(d) baseline assumptions), and continuous data-quality monitoring with threshold alerts and logged remediation for the Art. 10(3) 'error-free and complete' standard.
from: Sovereign Resilient Enterprise Pattern
Isolated Tenant Storage EnclavePer-client storage boundary for raw payloads, intermediate artefacts and outputs, so no tenant data is co-mingled or reachable across engagements.
from: Sovereign Resilient Enterprise Pattern
Zero-Trust Ingestion GatewayAuthenticated, policy-checked entry point for client payloads; enforces tenant identity, schema validation and rate limits before any data reaches an inference path.
from: Sovereign Resilient Enterprise Pattern
Local Perimeter Execution (MCP)Execution agents run inside the corporate perimeter and reach tools through the Model Context Protocol instead of shipping raw records to third-party model endpoints. Context is scoped to the minimum attributes the task needs, which is how data minimisation (GDPR Art. 5(1)(c)) and Art. 25 privacy-by-design survive multi-tool agent orchestration.

Build or Buy — Vendor Layer (3)
The graph models vendor CATEGORIES as first-class nodes and keeps named vendors as community-maintained, disputable desc content with lastVerified dates. A category is stable; a vendor list is a currency-layer object like any standard node.
Agent Orchestration & SDLC ToolkitsDeveloper middleware for multi-agent networks, tool-use chains, RAG abstraction, state/memory persistence and model routing. Exemplary (community-maintained): LangChain, LlamaIndex, AutoGen, CrewAI; MCP-based tool ecosystems. Regulatory posture: orchestration code is where autonomy tiering, propose-action objects and fallback routing get implemented — the framework choice constrains which controls are cheap and which are retrofits.

Procurement rule: Derived from three-lines-of-defense separation: the second-line GRC platform must be procured and deployed independently of any first-line runtime or model vendor — a governance tool that only sees its own vendor's models cannot govern a multi-model estate, and closed third-party SaaS AI can only be governed contractually (intake, attestation, AI-BOM disclosure), never by inline inspection.
