The tag crosstab already ran a with-versus-without Welch test per structured
tag, with a D to D+1 pairing mode whose stated example was an evening tag
against next-day recovery. It only ever had one channel at that lag, and a
recovery score is a wearable composite plenty of accounts never record. The
rated-factor board next to it has tested next-day resting heart rate and HRV
since v1.14.0, but a rated factor is a continuous score, so a binary tag never
reached either vital.
Add both to the tag map. Same engine, same per-side day floors, same
Benjamini-Hochberg family, same card. The fetch filter derives from the map, so
the channels come along without a second query.
The delta read-out goes neutral to match the rated-factor board: with resting
heart rate on the board, a positive delta is worse on one row and better on the
next, and a green plus sign would claim a verdict the association cannot carry.
