The tile-maps are managed on CPU and associated with each light shadow object.
The number of tile-maps & tiles is unbounded (to the limit of SSBOs), but the actual number used for rendering is caped to 4096. This is to simplify tile-maps management on CPU.
At sync end, all tile-maps are grouped by light inside the ShadowTileMapDataBuf so that each light has a contiguous range of tile-maps to refer to.
