The ramp data in EmitsPointsInTimeOrder never produced a bucket whose maximum
preceded its minimum, so an implementation ordering the emitted pair by value
instead of by time would have passed. Replaced with an explicit two-bucket case
whose second bucket reverses the order.
file(COPY) is a hard configure error on a missing source, so a checkout without
the sibling StreamHub resources failed to configure despite the ASCII-icon
fallback the block above had just selected.
Plan amended to match on both points.
