Why it is a challenger rather than a duplicate

The four current entries cover dead code (vulture), wrapping other linters (prospector), repo-wide intelligence (repowise) and cognitive complexity (complexipy). thailint's two distinctive checks are not in any of them:

• Cross-file duplicate detection — duplicated blocks across a whole tree, not within a file.
• Unjustified suppressions — # noqa and friends added without a stated reason, which is a common way AI-written code quietly silences a linter.

The framing is anti-patterns that appear disproportionately in AI-generated code, which is what separates it from the general-purpose analyzers already listed.

On the download ranking: at ~12.9k/month I am well below vulture, prospector and complexipy, so I am proposing this as one of the two challenger slots rather than as an obvious choice. Entirely understand if you would rather hold the slot open.
