Required Technical Components (20)
Zero-Data-Retention Vendor BindingSensitive inference is contractually and technically restricted to endpoints under zero-data-retention and non-training terms, evidenced per vendor and re-validated annually.
from: Art. 25
SBOM & Dependency ManagementSoftware bill of materials incl. model weights and datasets; automated vulnerability patching pipeline.
from: Cyber Resilience Act
Secure Boot & Hardened RuntimeVerified boot chain and hardened runtimes for edge/IoT deployments per CRA security-by-design.
from: Cyber Resilience Act
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.

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.
Runtime Security & Guardrail VendorsFirst-line inline enforcement: single-pass parallel input/output evaluation proxies, injection & exfiltration defense, PII masking, grounding checks, SecOps routing. Exemplary (community-maintained): Prompt Security, HiddenLayer (MLSDR), Palo Alto AI Runtime Security, AWS Bedrock Guardrails, NVIDIA NeMo Guardrails, Guardrails AI, Robust Intelligence, LLM Guard / Llama Guard OSS class. Selection metrics: single-pass latency (<20 ms class), catch rates, policy-version telemetry into the AI-BOM.

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.

Regulated Foundation-Model PlatformsFrontier commercial APIs and open-weight models under enterprise controls: zero-data-retention tiers, data isolation, fine-tuning governance, safety alignment documentation, EU-sovereign options. Exemplary (community-maintained): Anthropic Claude (ZDR enterprise tier), OpenAI GPT enterprise, Google Gemini Enterprise, Cohere (private-cloud RAG), Mistral (EU/self-hosted), Meta Llama (open-weight sovereignty). GPAI-chapter duties and vendor due diligence attach at this layer.

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.
