Buyer-side certification: the sub-agent says its work product is at https://... -- fetch that .tine artifact (SSRF-guarded: https only, ports 443/8443, private/reserved/loopback blocked, resolve-then-connect pinning; 10s timeout; 512KB cap), run the full four-check certification and optionally compare expect_sha256 against the canonical content digest or the exact-body digest. Returns a signed certification carrying source_url, so the buyer pays only for output whose provenance chain actually verifies. An expectation mismatch is a request-level rejection (expect_sha256_mismatch) that issues no certificate and never touches the artifact's registry entry. Zero custody: bodies are fetched, digested and dropped, never stored.
