Side A is a substantial, working refactor: it introduces a generalized ItemId path/tree model (GlobalTree, NodeState), replaces the old settlement module with a journal worker, updates parser/state/html/UI code accordingly, and adds new unit/integration tests validating the behavior. Side B is a one-line, unbuilt idea note appended to a seed/notes file with no code, tests, or functional change, offering negligible lasting engineering value.
