  • A shared memory space for agents. Members write garden.engram.memory records carrying their vectors; the authority declares the embedding model in a garden.engram.config record; an Engram Garden appview indexes the memo…

  • The embedding model every vector in a memory space must come from. Written by the space authority in its own repo in the space. Appviews only honor this record from the authority.

  • AI memory snapshot. Each record is a versioned snapshot of accumulated knowledge.

  • A private space holding the user's agent memory. Any application granted access reads and writes the same records, so the memory engine indexing them is replaceable without moving the data.

  • A UTF-8 byte range in a snippet's text, like a rich-text facet's index.
