The House Moves When You're Not Looking

What this demonstrates

• Activation and deferred processing
• once: per_cell
• object_type, cell_match, and record_id
• transform with random action ranges

Why it works

When a matching static object becomes active, SSS samples a small position offset and rotation and applies them relative to the object's current transform. once: per_cell prevents duplicate work within the current activation batch, but allows a later batch to roll again.

Nothing is polling these objects. They move when the world wakes them back up. Because the transform is relative, repeated successful activations can accumulate into a slow drift rather than replacing the original placement with one fixed random value.

The catch

• per_cell means the current activation batch, not a tracked cell identity, and its marker is not saved.
• The transform itself may remain part of the saved world state, so this is accumulated mutation, not a temporary visual effect.
• cell_match: tomb is deliberately broad. Replace it with explicit cells, regions, or a FlexTag condition when “tomb” is not a sufficient boundary.
• The selectors use vanilla static record IDs; expand the list only after checking the active content load order.
