Closes #100. rhet.rule-of-three matched any three word-characters, so it could not tell a rhetorical tricolon ("fast, simple, and powerful") from an author listing three values. #100 found it on "2324, 2425 and 2526" in a support-ticket reply and measured it: 18 of the rule's 236 corpus matches are lists like that -- gene names, dose numbers, year codes -- and six texts had no other hit. The narrowing is in the pack, not in C#, so the rule stays editable by anyone: a list is skipped when none of its three items contains a lowercase letter. Two traps shaped the regex: - PatternAnalyzer compiles every pack pattern with IgnoreCase, so an uppercase class would match prose too. The token class is wrapped in (?-i:...). - \p{Lu}, not [A-Z]: an ASCII class misses an accented acronym, which is what the Turkish dotless i taught this project a week ago. Mixed lists still fire ("CD31, CD45, and cells"): requiring all three items to be data is the conservative reading #100 argued for. The Spanish twin, rhet.regla-de-tres, gets the same narrowing. The Spanish corpus cannot judge it -- 14 matches, none of them data -- but the reasoning is language-independent, and leaving the two packs asymmetric is how a sibling goes stale. Published numbers: unchanged in every field. The calibration run was compared before and after the regex change, and the only fields that differ from the committed file are engine and measuredOn -- which is why that file is not regenerated here. humanRatePer1000 is deliberately left at 1.09: it was measured on a superset of these matches, so it is now slightly generous, and refitting one rule's rate in isolation is the trap #75 describes. SKILL.md told agents to "vary the count" on tricolons, which in edit mode would rewrite someone's data. It now says a list of data is not one. Verified by mutation: with the original regexes, all 12 data-list tests fail. 393 + 72 + 7, plus the desktop job's 31.

A list of data is not a tricolon
