The index has published run_mp, omni, clan, config, source, rules_level and mul_id since it existed and the type declared none of them, so a screen could not read one without a cast. The breaking half is `heat`: the index carries dissipation less firing heat, so a positive figure meant a cool machine and `heat>=10` returned the opposite of what it asked for. It now filters on heat the sinks cannot shed, read through the one accessor the screen reads, so `heat<=0` is the design that can keep firing. `run`, `damage` and `range` join the keys, each a column that is now visible on a row.
