Probes a live public URL against your expectation and returns a cryptographically signed Ed25519 verdict with network-level evidence (TLS fingerprint, resolved address, response headers, body hash, timestamp).

Returns a signed pass/fail verdict document verifying a deliverable against deterministic acceptance checks (JSON Schema, JSON path, content hash, regex, length bounds), suitable as escrow-release evidence.

Runs up to three live network probes (HTTP status, keyword, CSS selector, JSON path) against public URLs alongside other checks, returning an Ed25519-signed pass/fail verdict for verifying delivered work before releasing escrow.

Runs a deliverable through all acceptance checks twice, spaced ~1 minute apart, and issues a cryptographically signed pass/fail verdict only if both passes succeed — designed for ERC-8183 escrow release evidence.
