Intent

Duplicate parameter identities are ambiguous for validators, generators, and callers.

See it fail

parameters:
  - { in: query, name: status, schema: { type: string } }
  - { in: query, name: status, schema: { type: string } }

Same name in different locations, such as query and header, is allowed.

Fix it

Keep one definition or give each parameter a distinct identity.

Configure under profiles.<name>.rules.override.operation-parameters-unique.
