`query-percent-encoded`

Disallows allowReserved: true on query parameters.

Intent

Encoding reserved characters prevents parameter values from changing the meaning or structure of the query string.

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

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

- name: filter
  in: query
  allowReserved: true
  schema:
    type: string

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

- name: filter
  in: query
  allowReserved: false
  schema:
    type: string

Omitting allowReserved has the same false default.
