For safety, the default implementation applies two fixed limits: maxQueryStringLength = 64 * 1024 (65,536 characters) and maxQueryParameterCount = 1024 (&-separated parameter pairs). These implementation values are not exposed as runtime configuration. Requests that exceed either limit or contain invalid percent-encoding are rejected by the scrape handler with HTTP 400 Bad Request.
