check / check (push) Failing after 1m53s
Each discriminator check is now a type in its own file behind one small interface, listed in `heuristics.go`. Adding a heuristic is one file and one line. Behaviour does not change. Refusal and ban log lines gain `heuristic` and `heuristic_figures`. A ban after the answer, by `refusal_limit` or `byte_limits`, logs `after_answer_heuristic` and its figures, so one line can name both. Deviation: four lists, not the planned three, so `refusal_limit` still bans at the decision. Rule suppressed: `//nolint:lll` on one struct tag. Model: opus-5-5
