🔏 Signed receipt rr_0ad707ad91d13847095a8c9e · 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 (1 shown, 2026-09-13 → 2026-09-13). 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 tool names/descriptions/annotations WE OBSERVED. What checking applies to each kind (the full methodology →):

naturetoolsmeaning what checking applies
computational15deterministic transformsself-checkable by re-computation and known-answer tests
retrieval-public10serves public factstruth-checkable against a public source — the V-ladder applies in full
generative5creates contentno answer key exists; disclosure + stability checks, never truth verdicts
predictive1claims about the futurescoreable only in retrospect — the archive scores yesterday's predictions against today's outcome

Harness readiness observed

Can an agent's harness pick this tool and call it correctly? Graded on the three things an agent reads — name, description, typed parameters. Band A — an agent can pick and call these reliably.

31 of 31 tools graded · 31 with a captured input schema. RS-008, Tier-1 — no domain knowledge, applies to any tool. “Alive” is not the same as “usable”.

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.
