History audit: recorded hub switches / setpoints / flags and the brain’s computed entities were unreachable or never persisted

switch.dsc_hub_demand rows existed but only grow_mat was mapped, so Heater/Cool/Hum/Dehum inspectors reported tracked:false; number.dsc_hub setpoints, mode switches and hub binaries were never recorded (no band history, no takeover timeline); computed entities (lights_on_today, deviation, runtime, alert flags) existed only while a browser polled. Now: generic resolver, throttled recording (on change or 5 min), brain-owned 60 s computed recorder under seat ‘computed’. SPA shows NOT RECORDED BY THE BRAIN when tracked is false (verified against the Pi’s old brain). New metrics start at hotpatch time — no back-fill.
