Minds
Cards can author provider-independent persona, belief, and memory declarations. Those local content contracts remain part of Worker composition, but Darwinian 1.4.2 selects no persistence backend for a running Worker Mind.
drwn worker mind is therefore a deliberate placeholder. It returns
MIND_BACKEND_UNSELECTED and performs no filesystem, network, BeginningDB, R2,
S3, or provider discovery. There are no nested provision, status, sync, diff,
checkpoint, doctor, or pool-retirement verbs.
This separation lets Card authors continue composing persona and belief content without treating a storage provider as deployment or authorization authority. A future backend requires its own reviewed architecture and command contract.
