sneak	4a2d57dca2	servewaf answers rproxy's question about each request and takes its report (closes #170) ... `smallwebwaf servewaf` runs today's checks on the visitor's request each question carries, answers rproxy, and passes nothing to an app. rproxy reports every request servewaf answered. A report counts an allowed request's bytes and writes servewaf's second log line. The table holds a copy of what a report needs, never the request, so a report cannot reach a request being handled. Judgement call: a question's body is read before any check; over 64 KiB gets 400. Judgement call: a report's bytes and durations have ceilings, so they cannot overflow. Judgement call: a `close` disposition for SWWAF_BAN_RESPONSE=close. Model: opus-5-5	2026-11-04 21:10:03 +00:00
clawbot	82e20e0cb5	Anomaly thresholds: alerts for unusual traffic, nothing refused (closes #101) ... SWWAF_ANOMALY_CLIENT_*, _NET_*, _ASN_*, _TOTAL_* and SWWAF_WATCH_* with SWWAF_WATCH_NETS: requests and bytes per minute and per hour, each off by default; with all off, nothing is counted. Otherwise every request but the health check is counted, allow-listed and exempt ones included; a count over its threshold raises an anomaly alert, with a cooldown per scope. At most 20,000 counters, kept in alerts.json. A per-AS-number threshold with lookups off, or a malformed SWWAF_WATCH_NETS, stops the start. A cooldown that has run out is dropped as the hour ends, whatever it held back; the hour's summary gives its repeats. Judgement call: refused requests are counted too. Judgement call: per-client counters are kept in alerts.json, which SPEC.md does not list. Judgement call: a request counts for an AS number only if the lookup answered before it ended.

clawbot	70a8ea1b92	Alerts to Slack and ntfy, each destination with its own queue (closes #90) ... Each alert is posted as a message to the Slack incoming webhook SWWAF_ALERT_SLACK_WEBHOOK_URL names, and published to the ntfy topic SWWAF_ALERT_NTFY_URL names, with SWWAF_ALERT_NTFY_TOKEN as a bearer token and a priority and tag by event. The cooldown and the hourly limit stay shared; past them, each destination has its own bounded queue and backoff, and its own sent, failed and dropped counts. alerts.json keeps the alerts waiting by destination; one whose waiting is still a list stops the start, saying what to change. A control character in the ntfy token, or in the instance name ntfy is sent, stops the start. Judgement call: messages also give the detail's file, source, error and mode. Judgement call: alerts_suppressed_total is the same for every destination. Model: opus-5-5	2026-10-07 05:54:34 +02:00
clawbot	432097ee3f	Alerts to a JSON webhook, with a cooldown and an hourly summary (closes #26) ... SWWAF_ALERT_WEBHOOK_URL gets one JSON POST per alert, in SPEC.md's schema, with SWWAF_ALERT_WEBHOOK_HEADERS: ban and permanent_ban, with the ban's notes, in observe mode too, marked mode observe and worked out only when the alert would be sent; source_failure for GeoJS; file_error for a rule or state file with an error. SWWAF_ALERT_EVENTS chooses; SWWAF_ALERT_COOLDOWN holds back repeats by netblock, file or source; past SWWAF_ALERT_MAX_PER_HOUR the hour ends in one summary. A bounded queue, retried with backoff, holds up no request; a 4xx other than 408 and 429 gives the alert up. alerts.json keeps the queue, the cooldowns and the hour. Nothing shows the URL's path or query. Judgement call: the summary's event is summary, which SPEC.md omits. Judgement call: an admin's ban raises no alert. Model: opus-5-5	2026-10-07 04:21:24 +02:00
