ARCH-02: M7's evidence was filtered out by its own finding kind

The mutation battery prints the distinct findings each mutation caused, matched
on the finding's KIND. The pattern's character class was `[A-Z -]`, which has no
underscore - so `UNIQUE_ID DRIFT:` did not match, and M7, the mutation that
renames `mqtt.BASE`, printed its verdict with no evidence under it at all.

A filter that silently drops the very finding a mutation exists to produce is
the same defect as the rest of this card, at display scale. No behaviour change:
M7 was red before and is red now, and it now shows why.
