branchStoredSession looked its parent up in $sessions alone, and
branchCurrentSession did the same. A conversation reachable through a
profile-scoped project tree has no row there, and when it appears in both
places the flat Recents copy is the ownerless one — so the lookup returned
the row that cannot route, and the branch created its child on whichever
backend happened to be active.
cachedSessionRow spans Recents, cron, messaging and the project tree, and
prefers the self-describing candidate. One ladder, used by both branch
entry points and by resolveStoredSession.
