Wrong Yellow Matrix V2.1
- source_01.nbt is compiled to storage and erased immediately; no visible roof matrix
- runtime source reads no longer forceload or inspect world blocks
- split body restored to old fine-grained cadence: one 16x48x8 layer every 2 ticks
- top body uses one 16x24x8 placement every 2 ticks
- caps and crosses are also vertically segmented
- local 16-block slices build from macrocell centre outward
- macrocell queue still builds from the discovered source cell outward
- each slice forceload is added at its first layer and removed after its top layer
- conservative level-0 light pulse after each placed layer to encourage relighting
- matrix topology, rotations, 50/50 air contents and matrix_version remain unchanged
