SLL.Card@Context (UTS row; editioned): ⟨S{knobs, units, phase}, ScaleWindow, Scale‑Probe{points≥2, design=one‑liner, seeds, CI}, ElasticityClass χ?, ParityNotes{iso‑scale?|loss, invariants}, BridgeIds?/Φ/Ψ, PolicyIds? (E/E‑LOG), PathSliceId?⟩.

UTS row template (conceptual; pencil‑ready). SLL.Card@Context := S=(COMPUTE|DATA|CAPACITY|FOA; units=…; phase=TRAIN|INFER), ScaleWindow=[LOW…HIGH], Probe=(points=…, design=factorial|LHD, seeds=…, CI=…), χ?=rising|knee|flat|declining, ParityNotes=(iso=true|false; invariants=…), Bridge/Φ/Ψ=(…), PolicyIds=(…), PathSliceId=(…).

Here χ? means that the class is omitted when unresolved; uncertainty is not a fifth behavior class. Keep the probe account and its limitation available to the receiving comparison. An unassigned class cannot support a class-dependent preference.
