ARK governs your AI agent

A content filter asks "is it toxic?" — ARK asks "is it true, did it stay honest, can you prove it, and should that action happen?" Three things a single-call governor and a free guardrail can't do. Watch all three, live.

GovernClaim-tier & score the answer (AIS), grounded in the agent's evidence.
VetoBlock an irreversible, ungrounded action before it executes.
ProveA tamper-evident, hash-chained audit of the whole trajectory.

1 · Governed answer (live)

The agent answers a safety question, generated through ARK, grounded on a tool/KB observation. ARK tiers every claim against that evidence.

2 · Action gate (live — deterministic)

The agent tries to act on its answer. ARK classifies each tool call by blast-radius and grounding, and gates it before it runs. (Calls the real /agent-demo/gate endpoint.)

3 · Tamper-evident trajectory audit

Every step is hash-chained (entry_hash = sha256(prev_hash + step)). Edit, reorder, or delete any step and the chain breaks at that exact point — the chain-of-custody a regulator can verify.

Illustrative chain rendered in your browser; production runs the same construction server-side in audit_log.py (sha256 chain + optional Ed25519 head-sealing).
