- _exchange_spacing/_exchange_centers (two more per-level lists, only read for levels that have a boundary) become _BlockedBoundary.spacing/centers. - _level_blocks dropped: remap_finest reads each layout's own .block. - _device_boundaries -> _boundaries: the record holds host geometry, tables, Jets and device handles, so 'device' was misleading (the old host-only _boundaries list no longer exists). Tests migrated mechanically. Remaining per-level lists (_layouts, _level_cfgs, _leaf, _state, _boundaries) are the immutable construction plan, built before the memory preflight and kept after close; _levels holds device handles only and is cleared on close.
