Axiom Service
Governance before execution. Evaluates every proposed action against your policies. Returns ALLOW, BLOCK, or ESCALATE — producing a signed Governance Decision AEA on every call.
How autonomous systems call Ardyn to govern actions, verify outcomes, and produce independently verifiable evidence — without exposing the cryptographic substrate.
External AI agents call the Ardyn Trust Plane whenever trust decisions are required. Six Services handle governance, verification, trust, policy, release gating, and metering — every decision capable of producing a cryptographically verifiable AEA.
Each Service answers a specific trust question. Together they form the complete Trust Plane — your AI systems call in, verifiable evidence comes out.
Governance before execution. Evaluates every proposed action against your policies. Returns ALLOW, BLOCK, or ESCALATE — producing a signed Governance Decision AEA on every call.
Artifact verification. Look up any AEA by ID to get full verification status: signature validity, chain integrity, policy compliance. Hardware attestation reports re-derived to pinned roots.
Trust scoring and authority. Agents earn standing over time from verified evidence. Trust scores gate what agents are authorized to do — the rating→authority flywheel.
Policy CRUD, versioning, diffing, and dry-run. Simulate policy changes against real history before activation. Every policy change signed and chain-recorded.
Software-Assured release gating. Evaluates policy and validates AEAs before permitting tool execution. Not an interlock — interlock is reserved for DDC.
Usage accounting. Tracks verified trust events across all Services. Powers billing and settlement — without exposing internal substrate details.
Every autonomous action calling the Trust Plane follows a constrained pipeline: governed → recorded → signed → verifiable.
The AI system calls POST /v1/governance/check before executing. Policy engine evaluates. Verdict returned. Signed Governance Decision AEA written to the ledger.
Any party calls POST /v1/verify/artifact with the AEA ID. The Verify Service returns artifact type, signature validity, chain validity, and policy validity — all re-derived from bytes.
Verified outcomes accumulate into trust profiles. Trust standing determines authority. Higher trust → broader permissions. The flywheel is: govern → verify → trust → authorize.
Every AEA carries every byte needed for offline verification. The ardyn-verify tool re-derives entry hashes, verifies signatures, and validates chain integrity — zero network calls, zero Ardyn contact.
The Ardyn platform spans five source repositories. Each has a distinct role in the architecture — from core evidence through to organizational cognition.
