Detailed Description

Per-stage metadata record written into the FZM header (256 bytes).

Describes one stage's type, configuration, and buffer connectivity. Used by decompressFromFile() to reconstruct the pipeline execution order.

stage_config holds the output of Stage::serializeHeader() — a stage-defined POD struct (e.g. LorenzoConfig, QuantizerConfig) packed into the 128-byte slot.
