Undo record no longer applies

The host cannot apply an undo record to the current world. Undo validates all steps before applying any, so a validation failure leaves the world unchanged. This code can also identify a host operation targeting an entity that no longer exists.

#Common causes

• A recorded entity is gone or no longer has the component state required by the undo.
• A component or resource schema/layout changed since the record was created.

#Fixes

• Inspect the named entity and schema mismatch; restore a compatible snapshot when the old undo must be replayed.

• Otherwise issue a new typed command against current entities and schemas to make the desired correction.
