Research direction

Start at the ngx.var.signature entry point and reproduce the GET request shown in the issue against lua-nginx-module. Trace how query parameters are exposed through ngx.var and compare the observed value with the request's signature parameter. Done means establishing whether the behavior is a module bug or an incorrect variable lookup, with a documented reproduction or a focused fix path.
