Refers to a type of update suppression/suppressor based on CCE that is state-less and does not require reset, broken in ≥1.20.2. This can be achieved by using Tile Entity Swap to make a shulker box have a tile entity that is not a container, and make a comparator read from the box. Updating the comparator (with Block Update or Comparator Update) will make the box attempt to treat the non-container tile entity as container tile entity to calculate output, which then throws a CCE. The suppressor can also be toggled by powering the comparator.
