WP-062 — the fidelity gate picked the stem width¶
A20 records that R1 gives the angle branch no width: sec. 3.4.3 says only "separate branch", Fig. S2 draws one stem shape and no numbers, and Table S11 reports whole-model sizes a branch width can only be inferred back out of. This is the package where that inference was made, and it was made by the gate rather than by argument — the Table S11 comparison at 1024 px over 15 classes selected the wider channels // 2 stem, and A20 was revised to it.
The margins say how much room the choice had: params bind at scale s, +3.27% against a ±3.5% band, and FLOPs at scale n, +4.84% against ±5%.
