The row's server __mj_UpdatedAt (ISO) that this snapshot is built on top of: the stamp of
the last save this browser saw complete, or of the row as loaded. Compared only with another
SERVER stamp, never with this browser's clock, so client clock skew cannot pick the wrong side.
The configuration itself.
OptionalInThe serialized configuration of a save this browser started but has not yet seen complete, or null/absent when no save is in flight. A save that lands on the server while the page is unloading advances the row's stamp past BaseUpdatedAt without this browser ever re-basing; matching the row against this value is how the next load recognises that newer row as its OWN write (which the snapshot already supersedes) rather than another device's.
The user the snapshot belongs to.
Format version of this entry; entries with another version are ignored.
The MJ: Workspaces row the snapshot was built on, or null when the user has none (permission-constrained sessions).
One browser-local snapshot of the user's workspace configuration.
The workspace is persisted to
MJ: Workspacesthrough a debounced, asynchronous entity save. A refresh that lands inside that window (debounce + network round trip) used to come back one step behind: the newest tab/selection change existed only in memory. The journal is written SYNCHRONOUSLY on every change, so the newest state survives any unload.
