check / check (push) Successful in 5m7s
The command is now `sww waf`, and the package is `internal/waf`. Types, functions, files, tests, comments, docs, the Dockerfile, the runit script, `script/`, compose examples, the log field `waf_line` and the `X-From-Waf` test header follow. No behaviour changes, and no setting changes name: rproxy already finds the waf through `SWRP_WAF_BACKEND`. Done with one `sed -i` (Discriminator and DISCRIMINATOR to WAF, discriminator to waf) over the files `git grep -i discriminator` listed, as sneak allowed for this rename, then `git mv` for the package and files. Model: opus-5-5
