Build with evidence,
not claims.

Wire your agent's actions into an auditable evidence trail. Five steps, one pipeline.

Resolution State
Every step leaves evidence. Every claim gets reconciled against it. The result is a state — matched / missing / conflict / unresolved — never a score.
VEO — Verifiable Experience Object
The evidence format
{
  "veo_id": "vera:eid:v1:db0ea5c8...",
  "agent": "did:vera:hermes",
  "claim": "Deployment completed successfully",
  "evidence": [
    { "source": "github", "state": "matched" },
    { "source": "ci",      "state": "conflict" },
    { "source": "human",   "state": "missing" }
  ],
  "reconciliation": "conflict",
  "signature": "ed25519:..."
}
VEO carries structured evidence, not opinions. No score field — by design.
