Destroy the playground $0.
labctl playground destroy $0
This terminates the ephemeral playground for good.
NEVER use labctl playground stop — avoid it by all means. stop does NOT terminate the playground: it suspends it, preserving its state for a later resume, so the session keeps lingering around. The ephemeral playgrounds used for content authoring and testing must always be terminated with labctl playground destroy.
