Module compositor 

Pixel-ownership compositing of one placement into one tile (docs/ARCHITECTURE.md §六–七).

This is the per-tile body of Compositor.add(): block-level conflict/replace decisions, coverage and provisional bookkeeping, and the pixel writes themselves. Tile-cache traversal, temporal-conflict records and diagnostics stay with the adapter, which owns storage.

Functions

composite_tile

Composites the part of world (region rect at its integer raster pose) that falls into tile (tx, ty). Blocks are independent (each owns its pixels, coverage bits and block entries), so rows of blocks are split across the pool; every count is an integer sum and the conflict list is rebuilt in (by, bx) order afterwards.
