smallwebwaf now copies its state to bans.json, clients.json and
lookups.json in SWWAF_STATE_DIR, as "Persistent state" in SPEC.md
describes, and reads them back at start, so a restart lifts no ban and
gives no client a fresh allowance. Each client gains a history, and a
ban's notes count the netblock's requests. bans.json is written
SWWAF_STATE_WRITE_DELAY after a ban, every file every
SWWAF_STATE_COUNTER_INTERVAL and at the stop, each through a synced
temporary file renamed over it. A file that does not parse, an unknown
version or an unwritable directory stops the start. The image gets
/var/lib/smallwebwaf, which the run script gives to the smallwebwaf user.
Deviation: no AS number or name, and no ban cause, reason or lifting yet.
Model: opus-5-5
Milestone 1, the repo's first code. smallwebwaf passes each request to the app and the answer back unchanged, streaming bodies and WebSocket upgrades, within four timeouts (client and app, request and response) and two size limits, and writes one JSON line per request to stdout. Every setting has an SWWAF_ name and a default, and an invalid value stops the start. The repo gets the standard layout: script/ entrypoints, make targets that call them, a Dockerfile that runs the checks, and the Gitea workflow.
Disclosure: SPEC.md changed. Go's server reads the request line and headers before smallwebwaf sees the request, so slow headers are closed without an answer, and neither slow nor oversized headers get a log line.
Disclosure: standard library only.
