Every control asked for here is a view choice, so none of them may reach the capture child — two dashboards watching the same room must be able to disagree about how to draw it without disturbing the measurement or each other. That set the shape of the change: the child now sends everything anyone might ask for, once, and each tile folds it down. Averaging (was "Reading") is Fast, Slow, Inf and None, and the child computes and sends all four every frame. Fast and Slow are the IEC time constants, Inf is Leq since reset, None is the block with no time constant at all. The admin-wide time constant is gone — it was never a property of the room. Banding is 1/3 through 1/48 octave. The wire always carries 1/48, and because every banding offered divides 48 a coarser band is an exact sum of finer ones in the power domain. Nothing is resampled and no tile's choice is visible to another. The transform grew to 16384 points to have bins fine enough to mean it; below roughly 200 Hz a 1/48 band is still narrower than one bin, which the Banding help says out loud rather than pretending. Each tile kind now carries its own settings, which is the fix for the complaint that started this: the RTA was offering an alarm threshold and a metric picker that did nothing to it. An entry's instanceSchema replaces the module's, so a gear popover only holds controls that change that tile. Also: frequency labels in three tiers that thin out as a tile narrows instead of smearing, gridlines off by default on both graphs, RTA smoothing as a damping factor on the drawn value only, a title-bar toggle to swap the spectrogram's axes, and the threshold blurb removed. Settings saved by 0.1.0 are mapped forward — a layout on a wall should not start reading dashes because a field was renamed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
