check / check (push) In progress
Rename too_large, rate_limited, rule_blocked and denied, and split banned into temporarily_banned and permanently_banned by whether the ban runs out. A request that makes a ban permanent gets permanently_banned. A ban rule, a trap path or a CrowdSec decision gets the value for the ban it makes, and in observe mode would_action names the ban enforce mode would have made. The offence kind rule_blocked follows, as a metric label and a key in clients.json. Model: opus-5-5
