Required Technical Components (23)
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.

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.

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.

Ephemeral Execution IsolationgVisor/Firecracker microVMs, read-only root, egress allowlists; container discarded after each task to prevent persistence of exploits.
from: Agentic RDA Stack (6 Layers)
Agentic Zero TrustUnique cryptographic identity per agent; short-lived, finely-scoped tokens (OAuth 2.1 + PKCE); On-Behalf-Of flow so an agent can never see more than its triggering user.
from: Agentic RDA Stack (6 Layers)
MCP Gateway / ProxyCentral chokepoint for agent tool traffic: default-deny tool ACLs (tools/list vs tools/call), schema & argument inspection, credential injection from vault, rate limits, full audit mirror. Regulatory root cause: the base MCP protocol enforces no authentication or authorization at protocol level — Host/Client/Server topology with Tools/Resources/Prompts primitives ships without an identity layer, so a policy-enforcing gateway is not optional hardening but the only place Art. 12/15 duties can be enforced for tool calls.
from: Agentic RDA Stack (6 Layers)
Guardrail Sidecar / InterceptionRule-based (NeMo/Colang), model-based (alignment checkers) and structural validators deployed as sidecar or gateway plugin (<50 ms), decoupling safety scaling from inference scaling.
from: Agentic RDA Stack (6 Layers)
Propose-Action ObjectsAgents never call target APIs directly: they emit typed proposal objects (endpoint, params, risk estimate, rationale) validated by the governance layer before execution; idempotent execution layer.
from: Agentic RDA Stack (6 Layers)
Durable Checkpointing (Pause & Resume)At oversight gates the complete operational state — working memory, conversation history, tool arguments, intermediate artifacts — is serialized into a durable checkpoint (fast KV store for sub-ms lookups, transactional backend as recovery anchor, vector store for semantic caching of past human decisions). On approval the agent deserializes and resumes at the exact step; matched precedents can shortcut re-planning entirely.
from: Agentic RDA Stack (6 Layers)
Per-Action Autonomy TieringTools tagged read-only / reversible-write / irreversible-write; controls layer routes each action to the matching oversight mode. Mode selection is per action type, never per agent.
from: Agentic RDA Stack (6 Layers)
Agent Identity & Access (IdP)Per-agent identities, short-lived scoped tokens, OBO flow enforcement — the identity substrate of agentic zero trust.
from: Agentic RDA Stack (6 Layers)
Central Credential VaultAgents never hold target-system keys; the gateway injects centrally managed credentials after policy checks.

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: Agentic RDA Stack (6 Layers)
WORM / Immutable Audit VaultAppend-only, hash-chained audit vault (WORM object-lock storage, AES-256 at rest, TLS 1.3 in transit). Guarantees tamper-evidence within the organization's trust domain — which stops your own team, but not an admin who can rebuild the vault. Pair with an external trust anchor and key ceremonies outside the operating team for evidence that holds against the insider scenario.
from: Agentic RDA Stack (6 Layers)
Watchdog Supervisor & Rate LimitingCost/iteration caps, loop detection, anomaly-triggered mandatory approval (CodeBuddy 'suspicious command override').
from: Agentic RDA Stack (6 Layers)
Trinity Defense (TCB + Command Gates + IFC)Treats the LLM as an untrusted proposal engine behind a hardened non-LLM Trusted Computing Base. Three pillars: (1) command gates — actions only via a Finite Action Calculus, authorized by a deterministic policy checker before any execution; (2) information-flow control — lattice labels stop confidential data flowing to low-trust sinks without audited declassification; (3) privilege separation — sandboxed low-privilege planner ingests untrusted input, isolated high-privilege worker executes only gate-approved, TCB-normalized actions. Grounded in the impossibility result: token content alone can never unforgeably separate commands from data.
from: Agentic RDA Stack (6 Layers)
Guardian Agents (Runtime Policy Enforcement)Autonomous supervisory agents outside the supervised agent's reasoning loop: stateful threat engines with graph-based cross-session history (catch multi-turn injection, gradual exfiltration, incremental privilege escalation), event-driven exposure visibility (permission drift, new connectors), and contextual risk correlation into unified issues — interception before execution, not post-hoc logging.
from: Agentic RDA Stack (6 Layers)
Deterministic Policy Engine (OPA / Cedar)Policy-as-code decision point (PDP) with enforcement points (PEP) in front of every tool call: versioned policies in Git, microsecond evaluation, typed action schemas — authorization decided outside the model's reasoning space, never in the prompt.
from: Agentic RDA Stack (6 Layers)
Shadow-Mode ExecutionRun governance controls in observe-and-score mode before enforcement: the policy engine and guardrails evaluate every agent action and log verdicts without blocking, yielding empirical false-positive/negative rates and calibrated thresholds. De-risks the enforcement cutover, produces baseline evidence for Art. 9 risk estimation, and is the standard migration path when retrofitting controls onto a live workflow.
from: Agentic RDA Stack (6 Layers)
Multi-Model Router & Fallback AbstractionAbstraction layer decoupling application logic from model providers: dynamic routing on capability, cost, latency SLA and regulatory constraint (sensitive-data classes pinned to ZDR private/VPC endpoints or on-prem open-weight instances); real-time health monitoring with automatic fallback to secondary endpoints or local fine-tuned models on outage/latency spikes. Discharges resilience duties (DORA-class), prevents provider lock-in, and makes model deprecations a routing-table change instead of a re-architecture. Router decisions are logged into the decision trace — model version per event is an audit-packet field.

Delivery Stack & Pipeline Stage (5)
Service-as-a-Software delivery: the engines, patterns and artifacts this workflow needs on top of the generic obligations.
See the full pipelineMaster-Data & Supplier Risk EngineNormalises BOM and supplier master data, scores supplier risk, and keeps the assessment trail required for due-diligence reporting.
Data Lineage & VersioningProvenance tracking of datasets, features and embeddings; write-time attribution (source, actor, timestamp, confidence).
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.
Human-on-the-Loop Statistical SamplingFor lower-risk batch workflows, agents execute autonomously while auditors review a statistically representative random sample per batch to track accuracy, error classes and drift.
Active-Learning Feedback LoopHuman corrections at oversight gates are serialized as structured data — original context, model proposal, human edit, rationale — and fed into fine-tuning pipelines and prompt registries, systematically reducing future escalation rates instead of dying in review UIs.
Build or Buy — Vendor Layer (4)
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.
