The ninth named group, and a pure query: it reads no shared state, so it has no qualifier sites at all. Two things this group forced. The generator now drops lint directive lines before the transform, because a directive inside an expression makes esbuild parenthesise that expression to keep the comment where it was, and those parentheses are tokens the document does not have. And the two regexes keep their `no-useless-escape` escapes behind a line-scoped disable, for the same reason the theme group keeps `Math.pow`. One name the document declares twice in one function stays `var`. Two block-scoped declarations would be two bindings where the document has one, and esbuild renames the inner one to say so. Counts: qualified 0, scope declarations 0, rebindings 31, braced bodies 20, unbound catches 0, number properties 2. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

|
|
* The per-group tests compare a real module against the string the document carries, which says
|
|
* the two agree; these say why, on inputs small enough to read. The import and export cases are
|
|
* the ones that bit: esbuild wraps a long list across lines, and skipping only the first line
