check / check (push) Waiting to run
Applies the setting renames of the naming audit under the SWW_WAF_ and SWW_RPROXY_ prefixes, with sneak's names for the IP reputation cache time and the two time limits, which now take milliseconds. The rproxy log field default_disposition becomes waf_backend_no_answer, and config.Config and config.FromEnvironment become config.WAF and config.WAFFromEnvironment. Go fields, test names and prose follow. No aliases; nothing reads the old names. Model: opus-5-5
