check / check (push) Failing after 1m19s
Each check servewaf runs on a request is a type in its own file behind one interface, heuristic, and is registered in one of four ordered lists in heuristics.go. Order and behaviour are unchanged. Every refusal or ban now logs heuristic, the name of the heuristic that made it, and heuristic_figures, the figures it acted on. Both are in docs/request-log.md, and SPEC.md names each heuristic at its step. Model: opus-5-5
