Cross-interface consistency findings are deterministic evidence. Change compatibility is classified separately in Changes below.
Only explicit identities and mappings are compared. Name similarity is never used.
ARD declaration and A2A observation refer to https://sample-agent.invalid/.well-known/agent-card.json.
The ARD-declared artifact was observed and validated as OpenAPI 3.1.2.
MCP advertised prompts and the passive list completed.
MCP advertised resources and the passive list completed.
MCP advertised tools and the passive list completed.
OpenAPI and MCP carry the same valid explicit publisher-provided capability identifier.
Input equivalence could not be proven within the supported fragment.
InterfaceDelta deliberately refused to claim equivalence because the current deterministic evidence was insufficient or unsupported.
The explicitly mapped declared output schemas are equivalent within the supported deterministic fragment.
A concrete OpenAPI server declaration resolves to the inspected subject origin.

What changed
“limit” is now required; before, it could be omitted.
Why
A caller that previously omitted this property may no longer satisfy the current input schema.

The origin root HTML, or a monitor’s watched page, declared WebMCP form tools. InterfaceDelta ran no scripts and submitted no forms.
What this does not mean
A declaration does not prove the tool works. WebMCP is an experimental browser capability.
InterfaceDelta retrieved the document within the passive observation boundary.
What this does not mean
Retrieving a publisher document does not prove every claim inside it is operationally correct.
InterfaceDelta retrieved the document and recorded it as usable within the protocol observation.

What this does not mean
Retrieving a publisher document does not prove every claim inside it is operationally correct.
InterfaceDelta deterministically canonicalized the inspected subject as https://sample-agent.invalid.
InterfaceDelta deterministically fingerprinted the canonical Passport projection.
What this does not mean
A fingerprint is not a signature, certificate, or trust rating.
A usable protocol document was retrieved and validated.
The endpoint declaration was retained without actively probing it.
What this does not mean
Not probed does not establish whether the endpoint is operational.
Publisher metadata declared this endpoint location.
What this does not mean
The declaration alone does not prove the endpoint is reachable or correct.
