Parity-bisect helper: run ONLY the block chain (+ optional merger) on a caller-provided hidden grid — used to separate patch-embed seed ulp from block-math divergence in the stage gates.
Encode one preprocessed image → [imageTokens, 5120] bf16.
Optionaltap: (name: string, arr: MlxArray) => voidStage-instrumented encode for parity bisection: returns named f32 copies of each pipeline stage alongside the final output.

Computed once, under native preparation. Exact weight content prevents cross-artifact SSD reuse even when model aliases and shapes are identical.
