pub fn propagate_block_light_chunk(
workset: &LightWorkset,
edge_checks: BlockLightChunkEdgeChecks,
) -> Result<BlockLightUpdateResult, BlockLightPropagationContextError>Expand description
Seeds and propagates block light for the center chunk of a scoped workset.
This matches ScalableLux BlockStarLightEngine.lightChunk: source blocks in
the center chunk are seeded, then the caller chooses between validating edge
consistency or pulling already-initialized neighbor levels inward.
