`all_sd_variables` – operational

Auto-select every variable in fred_sd_variable_group.

Default; uses the full set defined by the active variable group.

Configures the sd_variable_selection axis on l1_d (layer l1); the all_sd_variables value is materialised in the recipe’s fixed_axes block under that sub-layer.

When to use

Default broad-spectrum study. Selecting all_sd_variables on l1.sd_variable_selection activates this branch of the layer’s runtime.

`selected_sd_variables` – operational

Use the explicit per-series list in leaf_config.

Reads leaf_config.selected_sd_variables – a subset of the active variable group.

When to use

Targeted studies that focus on specific FRED-SD series.
