Twenty-two tests over the pass-7 surface: the tick's three stages and its
re-derivation at apply and at replay, the clock capability's single admitted
body, every commitment shape check as one complete sorted set, the attention
order's totality and its refusal to filter, boundary derivation and the
answer-must-be-satisfied rule, and the scale deficit that only admitted
subjects reduce.
Two defects the tests found and this commit fixes: PressureSource mixed struct
and newtype variants under an internal tag, which cannot serialize a scalar
newtype, so it is adjacently tagged; and Motion carried an is_empty no caller
outside a test used.
