Two Modes of Execution Assurance

Ardyn supports both evidence-first monitoring for external systems and full deterministic control for controlled environments. Deployment mode is determined by integration architecture and assurance requirements.

Attested Mode

Third-Party AI Systems

For external model providers and hosted AI systems. Ardyn binds policy, records execution evidence, seals attestations, and commits artifacts without making hardware control claims.

  • Policy-bound logging and execution records
  • Signed attestation and evidence bundles
  • DDC commitment for downstream auditability
  • No hardware-rooted destruction guarantees implied
Sovereign Mode

Controlled Environments

For environments where Ardyn can enforce execution directly. Hardware-rooted attestation, state reversion, and proof generation create the highest assurance boundary for sensitive AI operations.

  • Hardware-rooted attestation and control plane enforcement
  • State reversion and destruction proof generation
  • Deterministic result release gating
  • Full evidence chain from execution to ledger anchor

What Ardyn Verifies

Every sovereignty event produces a deterministic set of verifiable claims. Results are released only after all applicable verification gates are satisfied.

Execution Boundary Established

The processing environment is verified before sensitive material crosses the trust boundary.

Policy Gates Satisfied

Operational rules, retention limits, and release conditions are enforced at execution time.

Data Residual Eliminated

Applicable residual state is destroyed or reverted prior to any downstream release action.

Evidence Chain Committed

Artifacts, measurements, and attestations are cryptographically linked into a single chain.

Destruction Proof Generated

Destruction events produce portable proof objects suitable for internal or third-party verification.

Ledger Entry Anchored

A tamper-evident record is anchored for later audit, reporting, settlement, and claims review.

Isolated Execution Boundary

Every AI operation passes through an Ardyn-controlled execution boundary. Sensitive inputs are processed within attested isolation, and results are released only after verification.

01
Input Ingestion
Sensitive data enters the trust gate with tenant policy binding and release conditions.
02
Boundary Attestation
Execution environment claims are validated before processing begins.
03
Isolated Processing
The model executes within a controlled boundary with evidence collection active throughout.
04
Verified Release
Results are released only after applicable destruction and evidence checks pass.

State-Reversion & Proof Generation

After execution completes, Ardyn verifies that sensitive execution state is destroyed or reverted before any result leaves the boundary. Sovereign mode adds hardware-rooted verification for deeper non-retention assurance.

Tamper-Evident Evidence Chain

Each verified AI session produces a cryptographically linked trail from session creation to destruction proof, ledger commitment, and exportable audit evidence.

LEDGER
Immutable Record
Events are anchored into a tamper-evident record that supports external review and historical verification.
EVIDENCE
Portable Proof
Evidence bundles travel across compliance, legal, insurer, and internal governance workflows.
SETTLEMENT
Deterministic Metering
Usage tokens and session evidence stay cryptographically bound for reporting and liability settlement.

Case Study: Legal AI Underwriting

A legal workflow uses AI to analyze privileged material. The operating requirement is not just useful output, but proof that execution remained controlled, residual state was eliminated, and evidence is exportable for compliance or claims review.

01
Ingress — Privileged Documents Submitted
Privileged underwriting files are routed through an AI workflow with policy binding for zero-retention, jurisdictional controls, and restricted release handling.
02
Execution Boundary — Isolated Processing
The model executes inside an attested boundary with no uncontrolled egress path. Ardyn records the boundary conditions and release prerequisites before processing starts.
03
Verification — Destruction & Proof
After execution, retained state is destroyed or reverted. Destruction proof is generated, and the result remains blocked until verification completes.
04
DDC Issued — Evidence Committed
A DDC is issued with execution mode, policy reference, destruction proof, timestamps, and verification state. The record is committed for later audit.
05
Audit Export — Compliance Workflow
Evidence is exported to legal, compliance, or insurer stakeholders as a portable package supporting review, reporting, and liability transfer decisions.
Outcome
The organization can demonstrate that privileged AI processing occurred under verified non-retention conditions, with independent evidence rather than policy assertions alone.

Deployment Readiness

A pilot is designed to test the full evidence path, not just application connectivity.

  • MCP or API integration into a real workflow
  • Operational review of release gates and policies
  • Evidence generation and DDC artifact validation
  • SCU metering and settlement reporting paths
  • Audit export review with legal, risk, or compliance stakeholders
