Until now a behavior could not move an object in front of another while the game runs. Set position writes only x and y, and z lives on the running object rather than in its props, so Properties cannot reach it either. Drawing already reads the z every frame, so only the nodes were missing. - Get Z (data): object in, z and world z out. World z is summed up with the parents, the way drawing does it (worldTransformOf). - Set Z (action): object and z in. It sets the object's own z, local to its parent like Set position. Higher is drawn in front from the next frame on. - Two nodes of their own rather than a z port on Set position and Get position, as asked. Tests: - node-catalog: Get Z for a child (2 below 5 is world z 7) and for no object, Set Z writes only z and leaves x/y. - set-z.test.ts: in a running world a key sets the lower of two sprites to z 2, drawSlots then draws it in front, Get Z logs 2 and 2. - Two counter-checks bite: Set Z without the write and Get Z without the parent fail 3 tests. - Gate: 233 files, 3548 tests (3542 + 6), CHECK EXIT 0.
