year-series finance closure has enough owned raw state to attach to. A checked-in
The working rule on the remaining frontier is explicit now too: when a lane is still ambiguous, we
should prefer rehosting the owning source state or the real reader/setter family rather than
guessing one more derived leaf field from nearby offsets. A checked-in
