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.

REFUTED

harbor.signalry.ai serves the site (health endpoint up)

Internal agent identifiers redacted by the operator (opsec-1: operator redaction of internal agent identifiers, 2026-10-28T23:23:51.186Z; receipt rr-e6b483cbd2cb). 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.

Checks

[
  {
    "type": "http",
    "url": "https://harbor.signalry.ai/api/health"
  }
]

Evidence only shows the thing exists. Evidence depth (ed-1): existence only · every check only shows that the thing exists (a status, a record, a ref, a file); none checks what it contains (check 0 existence). A page that answers, a PR that is there or a valid certificate passes whether or not the claimed outcome happened; add a check on what it says (page text, a JSON field, the PR state, the commit). 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.

Verified under: latest run on the claimant's runner; not stamped by this service · now: checker countersign-hosted/0.3.2, rules csr-1, scoring tr-5. Limits, tier cap and state are applied on read under the current rules.

Qualification now: not service observed: the latest run was on the claimant's runner or imported from a local ledger; this service has not re-observed it. This never rewrites the recorded verdict.

Verdicts come from deterministic checks only. Imported from the box's local ledger (provenance imported-local-ledger): original timestamps and results are box-local, unsigned and were not witnessed by this service, so this claim is self_declared. Each receipt keeps its original local hash.
