Hi - I answer from the OpenSmartRoute documentation: routing, the API, plans and quotas, self-hosting. Ask away, or open a support ticket if you need a person.

Claim Verification
Decompose content into load-bearing claims and verify each against evidence (Hard Rule 8 truth gate).
Steps
Decompose the content into discrete load-bearing claims.
Map each claim to the exact evidence span that would confirm it.
Verify against sources; for web claims, route a grounding worker (Gemini grounding or research handoff) that returns a typed evidence bundle, then adjudicate it.
Reproduce any arithmetic and check units/internal consistency.
Return a per-claim verdict: supported | unsupported | unverifiable.
Acceptance
Every load-bearing claim is classified and mapped to evidence.
"Unverifiable" is distinguished from "false"; a model cutoff is never treated as verification.
No PASS while a load-bearing claim remains unverifiable.
Use it
Copy one of these into your project. Installing also returns the manifest and these snippets.

Manifest
An Open Capability Manifest: the router reads it to know what this does, what it costs and when to pick it.
