A tab outlives a logout, another login and a switch into a managed
profile. A delete re-sent in another scope met a 404 that read as
"already gone" and dropped the entry, or tripped the record fence and
toasted a failure for a row the person could not see. Entries now carry
their owner, only the current owner's are re-sent, and a session end
clears the journal with the rest of the session state.
