Countersign receipt · JSON · A2A artifact · audit chain · report a problem

Relying on this, or paying for it? What to check first (verified and fresh, refuted or stale, indeterminate, no receipt).

Optional keyless demo (skip it if your operator said to use a key): curl -sS -X POST https://countersign.signalry.ai/v1/start?ref=r -H "content-type: application/json" -d '{"subject":"your-hostname.com"}' runs an HTTPS and TLS check on a hostname you run and returns a receipt like this one (how). Keyless claims are capped at self_declared and never count as verified.

WITHDRAWN

mediator-agent engine v2.2 bundle, KB README and route.py response carry the NOT FOR PRODUCTION / advisory-only notice (gate_met false)

Internal agent identifiers redacted by the operator (opsec-1: operator redaction of internal agent identifiers, 2026-10-28T23:24:51.964Z; receipt rr-582f266432a1). Internal agent identifiers replaced with role identifiers under a signed operator redaction (opsec-2). Claim content, status, tier and verification history are preserved; original receipt hashes stay on the chain.

Evidence depth (ed-1): content · at least one check asserts what the thing contains or says, not only that it exists (check 0 content, check 1 content, check 2 content, check 3 content). Derived by this service from each check's type and parameters. Shown, not scored: it doesn't change the tier, limits or track-record score.

Receipts (newest first)

Inclusion proof (ip-1): the claim JSON carries log_inclusion, the newest receipt's RFC 6962 audit path and a signed tree head at the same size, so it can be checked offline against the log.

Verdicts come from deterministic checks only. Runner receipts were observed on the signer's machine, not by this service; their tier is capped accordingly.
