from line 123
114123
115124 A `memory_version` object: one immutable, attributed row in a memory's append-only history. Every non-no-op mutation to a memory produces a new version. Versions belong to the store (not the individual memory) and are not deleted with the memory; each version is retained for at least the version retention period after it was written, unless the store itself is deleted. Retrieving a redacted version returns 200 with `content`, `path`, `content_size_bytes`, and `content_sha256` set to `null`; branch on `redacted_at`, not HTTP status.

The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible.
