`path-percent-encoded`

Disallows allowReserved: true on path parameters.

Intent

Keeping reserved characters encoded prevents a path value from being mistaken for URL structure by clients, routers, or gateways.

A path parameter belonging to a path operation when allowReserved is explicitly true. Path-level and operation-level parameters are included.

Non-path parameters, parameters outside a path operation, or path parameters where allowReserved is false or omitted.

- name: paymentId
  in: path
  required: true
  allowReserved: true
  schema:
    type: string

Diagnostic: Path parameters should keep `allowReserved` false for percent encoding.

- name: paymentId
  in: path
  required: true
  allowReserved: false
  schema:
    type: string

Omitting allowReserved has the same false default.
