Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

popcorn_verify_v2read-only Verify a POPCORN-WITNESS/2.0 receipt against a caller-computed SHA-256 payload digest, nonce, and independently trusted issuer keys. Send only the digest, never private payload bytes. Caller-supplied keys do not establish issuer identity. This does not prove on-chain settlement, establish current time, or grant authority. Free and read-only.

Schemas: list_tools.
