Invalid terrain operation

ara-terrain reports invalid terrain data, authoring operations or tile cooking. Invalid authoring commands are rejected; a failed cook retains the last good tile rather than publishing the failed result.

#Common causes

• Terrain grid, layer, brush or tile data is invalid, a referenced payload is missing or corrupt, or a cook cannot run or exceeds its dependency/residency bounds.

#Fixes

• Correct the named grid, layer or brush fields through terrain commands; use power-of-two tile cell counts from 16 through 256 and layer opacity in 0..1.

• Split gestures touching more than 4096 tiles, reduce erosion stacks exceeding the 256-sample dependency halo, or increase residency capacity when a tile exceeds its budget.

• Restore the named terrain payload or worker executable, use a fresh unique job output path, then retry the cook.
