Verification
Checked 1 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
