Agent Plugins Conformance — Recovery
This fixture checks how clients handle invalid configuration while keeping valid plugin features available.
Install it alongside the other suite plugins and follow the run instructions.

The availability checks exercise the combined configuration. They do not evaluate diagnostics, determine how the client treated individual invalid entries, or isolate the effect of each invalid field or entry.
