Pull request overview
Updates Fusion gateway source-schema client configuration so transport capabilities are opt-out (defaulting to “all supported”), aligning runtime behavior with more permissive defaults and adding test coverage to lock in the new behavior.
Changes:
- Default
SourceSchemaClientCapabilitiesand supported operations toAllwhen capabilities aren’t explicitly restricted. - Update JSON capabilities parsing logic to remove capabilities/operations only when explicitly set to
false. - Add execution tests covering default behavior, opt-out flags, custom client names, and custom Accept formats.
