Bring a condition. Keep the evidence.

Supported verification inputs

File, browser, desktop, HTTP and permission-state readbacks are represented by supported verifiers. Each task defines its expected conditions and authorized sources. Support is scoped to the configured verifier and the synthetic release environment.

A claim is not a verdict

The engine independently reads authorized evidence. Observability traces and agent output are inputs, never independent evidence of success by themselves.

Stable result vocabulary

Consume the result per criterion and preserve evidence references. Do not flatten non-verified states into a boolean success flag.

• VERIFIED_PASS
