Detailed Description

Minimal context a fused runner hands a stage so it can establish the forward-computed state its OWN inverse will later read.

A fused pipeline reuses the same stage objects for decompress but bypasses their forward execute(), so any state normally computed there (e.g. a quantizer's resolved error bound from a value-range scan) must be primed explicitly, or the inverse reconstructs with defaults. See Stage::primeFusedForwardState.
