The opaque running activations of a layered net — one def per slot #
opaqueA k stem b1 … bk x is the activation after the k-th stage of a chain whose stages are
all still VARIABLES. Every whole-net certified backward tie states its apex over these: the tie
keeps its blocks opaque, and a *_eq_slots shape check says the concrete stages ARE the committed
forward. They are plain defs so the closing rfl of a tie can unfold them.
⭐ Net-agnostic and generic in every dimension. Until 2026-09-08 ResNet-34, EfficientNet-B0, MobileNetV2 and MobileNetV4 each carried a private copy of this construction — seventeen, seventeen, eighteen and twenty-five slots, under four names — and ResNet-50 reused ResNet-34's. One copy, to the deepest ladder in the suite.
