The mutation battery printed every line of the harness's output starting with a
warning sign, and the harness's header is four paragraphs of them - so each
mutation's evidence arrived buried under "THIS TOOL RUNS THE REAL Controller"
repeated six times, and each finding appeared once per transition leg plus once
in the summary. The filter now matches a finding's KIND and de-duplicates, so
what part 3 prints is the set of distinct findings the mutation caused.
No behaviour change: the same six mutations go red for the same reasons.
