`smallwebwaf` with no command now prints the commands and exits with status 2. The image runs rproxy, or servewaf with SMALLWEBWAF_COMMAND=servewaf. The passing-on code, its settings and its log fields and metric go. internal/proxy keeps the checks, answers, reports and own endpoints; its tests run through the real rproxy. The documents describe the pair. Judgement call: clients.json keeps token_refused, since state files refuse unknown fields. Deviation: script/gitea-requests sets SWWAF_LOG_REQUEST_HEADERS, to label requests. Model: opus-5-5

Admin endpoints
The endpoints under /_smallwebwaf/, what each takes and what each answers.
smallwebwaf servewaf answers them at its own address, on the private network.
"Admin endpoints" in SPEC.md says how their tokens work.
GET /_smallwebwaf/healthz:200andok, to anyone.GET /_smallwebwaf/metrics: the metrics, forSWWAF_METRICS_TOKEN(seemetrics.md).GET /_smallwebwaf/bans: every ban held, underbans, each asbans.jsonlists it. NeedsSWWAF_ADMIN_TOKEN, as do the three below.POST /_smallwebwaf/bans: bans a netblock. The body is a JSON object ofnetblock,durationand, if you like,reason.netblockis a netblock such as203.0.113.0/24, or a client's address, which bans its IPv4 netblock (SWWAF_BAN_SCOPE_V4_PREFIX) or its IPv6 group.durationis a duration such as1hor7d, orpermanent. A bad body is answered400, saying what is wrong:- one that is not such an object, or has another field;
- one longer than 4 KiB;
- one that names an IPv4-mapped netblock, or an address with a zone.
DELETE /_smallwebwaf/bans/<client>: lifts every active ban covering the address<client>. It answers404when none is active.GET /_smallwebwaf/clients/<ip>: whatservewafknows of the client. Underclient, its counters and history asclients.jsonholds them, ornullwhenclients.jsondoes not hold it. Underbans, every ban covering the address, with its notes.POST /_smallwebwaf/report: takesrproxy's report, without a token. It answers204, or400to a body that is no report (see "The report" inSPEC.md).
No check runs on these requests. A missing or wrong token is answered 401. An
endpoint whose token is unset answers 404, as does any other path.
smallwebwaf rproxy answers only the health check of these, at its own address.
It asks servewaf about any other request under /_smallwebwaf/. One that
passes the checks is answered 404, so that the app never sees that prefix (see
"rproxy" in SPEC.md).
