Update a memory store
⚠️
Preview — this feature is being built; the design below is the spec.
PATCH https://app.syntic.ai/v1/memory_stores/{store_id}Change a store’s settings. A lower max_memories_per_scope trims the oldest memories in each scope; a new default_ttl_days applies to memories written afterwards.
For how this fits into a full workflow, see Memory stores.
