 ## Returns
 
 - `BetaManagedAgentsMemoryVersion object`
 
-  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 persist after the memory 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.
+  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.
 
   - `id: string`
 

 
   - `memory_id: string`
 
-    ID of the memory this version snapshots (a `mem_...` value). Remains valid after the memory is deleted; pass it as `memory_id` to [List memory versions](/docs/en/api/beta/memory_stores/memory_versions/list) to retrieve the full lineage including the `deleted` row.

+- `BetaManagedAgentsMemoryVersion object`
 
   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 persist after the memory 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.

   - `memory_id: string`
 
     ID of the memory this version snapshots (a `mem_...` value). Remains valid after the memory is deleted; pass it as `memory_id` to [List memory versions](/docs/en/api/beta/memory_stores/memory_versions/list) to retrieve the full lineage including the `deleted` row.

 
   - `type: "memory_version"`
 
-    - `"memory_version"`
-
   - `content: optional string or null`
 
     The memory's UTF-8 text content as of this version. `null` when `view=basic`, when `operation` is `deleted`, or when `redacted_at` is set.

 
     Size of `content` in bytes as of this version. `null` when `redacted_at` is set or `operation` is `deleted`. Populated regardless of `view` otherwise.

   - `created_by: optional BetaManagedAgentsActor`
 
     Identifies who performed a write or redact operation. Captured at write time on the `memory_version` row. The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible. Look up session provenance separately via the [Sessions API](/docs/en/api/sessions-retrieve).

       Attribution for a write made by an agent during a session, through the mounted filesystem at `/mnt/memory/`.
 

 
         ID of the session that performed the write (a `sesn_...` value). Look up the session via [Retrieve a session](/docs/en/api/sessions-retrieve) for further provenance.
