Struct TransformFn 

pub struct TransformFn(/* private fields */);

The deterministic per-batch transform applied at delivery — the sanctioned home for augmentation. Receives the delivered rows (raw, already on the target device, freshly assembled — never aliasing the staging tiers) and one PickKey per row; must be a pure function of (rows, keys) and preserve the row count. Runs live on every delivery: retained tiers hold raw samples only, and each pick re-derives its view. Construct via the transform(..) builder setters (or TransformFn::new).
