CB-EV-0020: a gate moved the rule, and the report was wrong

The AM-1 coverage gate failed the build on GR-P05 being uncovered, which
is what showed the rule was in the offer layer rather than in validate.
A rule enforced only by the offer is enforced only for clients that ask
what is legal. The gate did not catch a bug, it caught a design error.

And the reported case was not the one reported. CB-WP-0018, CB-EV-0016
and the message to ground-game all described SOLVE offered on a
face-down Problem; validate already rejected face-down, so it never was.
Problem 1 is the Surface Problem, face-up from the deal, so the three
inert SOLVEs were the HAND case. The ruling covers both so nothing is
invalidated, but a ruling was requested on a wrong description -- the
second time in three passes that a premise reached ground-game
unchecked, after the '12 points available' that voided GR-E01.

Two of two. The pattern is not careless analysis; it is that a claim gets
SENT the moment it is interesting and checked afterwards. Unexecuted
verification, one step further out: not a belief acted on, but a belief
published. CB-WP-0022's reproduction rule would have caught both.

An earlier mutation run reported three survivors and was wrong -- the
replacement strings did not match, so nothing was mutated. It proved
nothing and looked like a result.

Also renames CB-WP-0022-T06B to T07; the hub flagged it as an
unregistered species.
