* docs/references/espectre-techniques.md — catalogues every Pace
technique from Part-2 against what RuView has implemented, doesn't
have, or has differently. Includes ranked open-items list.
* sensing-server: revert feature_state path to vec![] amplitudes.
The previous fix made bars LOOK live by reissuing the last raw-CSI
vector on every feature_state tick — operator reported this made
the bars misleading (visually busy but unresponsive to movement).
raw.html already skips empty-amp updates so bars now refresh only
on actual fresh CSI, which is honest.
* raw.html: comment on the skip-empty branch for future-me.
