CB-WP-0049 done; F27's aspect half closed

ModuleAwarePolicy reads the resolved Rules, so 'a bot that does not
attend to a mechanism cannot test claims about it' no longer holds for
modules. The MODE half stands: no policy models a rival playing their
objective, and that is the whole of what keeps F27 open.

Recorded the second limit found while closing the first: the scope term
is inert at round-one positions, so any measurement of
problem_stress.scoped weighted toward early rounds is measuring a
mechanism that has not started.
