🔏 Signed receipt rr_ffad21c75e81f85b639cc8a2 · 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 (3 shown, 2026-08-23 → 2026-09-06). 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 →):

nature	tools	meaning	what checking applies
retrieval-public	26	serves public facts	truth-checkable against a public source — the V-ladder applies in full
action	13	changes the world	no true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions
unclassified	9	not classifiable from its text	Tier-1 only until its tools describe themselves
generative	1	creates content	no answer key exists; disclosure + stability checks, never truth verdicts
predictive	1	claims about the future	scoreable 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 B — usable, with rough edges.

legibility check	tools passing	ok
name is clear & specific	50/50	✓
has a description	50/50	✓
description is substantive	50/50	✓
parameters are typed	50/50	✓
parameters are described	10/50	10/50

50 of 50 tools graded · 50 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.
