What

A 404 from the memory backend now says whether the store itself does not exist or just the document.

Details
  • The not-found error takes a kind, defaulting to "document"; memory-backend list and read paths construct it with "store".
  • Listing accepts size_bytes as a fallback when content_size_bytes is absent.
  • Listing now also records updated_at.
Evidence

(store not provisioned)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
