🔏 Signed receipt rr_cc8c2417788de8d7e33b0d64 · ed25519 · key rs-rcpt-2026-08 — this rating is tamper-evident; an agent gets the full signature from check_server and can verify it against the published key.

History observed
Every probe we made, oldest → newest (2 shown, 2026-08-12 → 2026-08-14). Green answered · amber answered-but-walled · red no useful answer. A gap in our cadence is a gap in coverage, not evidence about the server.

What kind of tools these are derived
Verification only means something relative to a tool's NATURE — an email-sender has no "true answer", a generator has no answer key. Classification evidence: classified from the operator's own registry description — REPORTED, not observed (tools were not visible to the probe). What checking applies to each kind (the full methodology →):
| nature | tools | meaning | what checking applies |
|---|---|---|---|
| retrieval-public | 1 | serves public facts | truth-checkable against a public source — the V-ladder applies in full |
Tools last seen observed
Truth checks observed
Not in the Tier-2 trade lane, or not yet checked. Tier-2 re-derives a server's answers against published primary sources — see truth checks.
Drift observed
No confirmed drift on record. Baseline set 2026-08-14; changes appear here after human review.

This server doesn't answer, but these live, allow-verdict servers describe themselves similarly — similar by what they say they do — never verified drop-in replacements; check each one before depending on it.
