Travel direction settled it: both rows travel LEFT->RIGHT, so both are pteff03
split across two keys by per-frame rounding. pteff03a is not in the capture.
So my 'the finding may still be correct via the OTHER row' does not apply --
there is no other row. I was right that size could not carry the assignment and
wrong about what the assignment was.
The larger half was not visible from here: the quoted low alphas were the nine
lowest DISTINCT values, not a series -- 14 sub-floor samples out of 1754. The
bound survives in shape and collapses in weight.
Status 🟡. Renderer still unchanged.
