check / check (push) Failing after 6m19s
Five failed asks to waf within five seconds open the breaker. An ask fails when it gets no answer in time, slow answers included, or an answer rproxy cannot pass on. Every usable answer clears the failures and closes the breaker. While open, a request takes SWW_RPROXY_WAF_BACKEND_NO_ANSWER_DISPOSITION without asking waf, except one ask a second. SPEC.md describes it. The sww test that stops and restarts waf now waits for the breaker to close before it expects the ban again. Model: opus-5-5
