Verified by repo-wide name search + transitive closure over internal
calls: the live apps use 25 methods (plus raw write/query); everything
else — cosmetic label styling, unused getters/setters, transfer_waveform,
acquire_waveform — had no callers. Also: linear-time chunk join in
read_raw instead of quadratic bytes += concat, and a typed except on its
debug path.
