BIT 4.3.1 is a patch release for divider rail and generated-divider controls introduced in 4.3.0.
Fixes:
- Allows DIV_RAIL_SIZE_XYZ Z height to be MAX, resolving to full compartment height.
- Defaults divider rail size to [wall_thickness / 2, wall_thickness, MAX].
- Keeps DIV_FRAME_SIZE_XY out of FTR_DIVIDERS while preserving it for standalone OBJECT_DIVIDERS.
- Fixes DIV_FRAME_RADIUS handling for divider frame openings.
- Fixes small DIV_TAB_SIZE_XY tabs so requested width/height are honored instead of growing by the tab radius.
- Improves divider rail validation diagnostics for malformed DIV_RAIL_SIZE_XYZ values.
Verification:
- Full CSG suite: 72 passed, 0 failed, 18 warning-classified validation tests.
- Focused divider CSG checks passed for rail MAX, frame controls, and validation cases.
- test_divider_frame_controls rendered successfully at 1600x1200.
- Package smoke compile passed.
