1// nx_js_accessor_probe.nx -- JS-SOTA: name the construct at the netflix frontier (2026-07-29).
2// After the Unicode-identifier fix, netflix's bundle fails inside TypeScript's downlevel
3// async helper at `t.trys.push([0,4,,5])` -- an ARRAY LITERAL WITH AN ELISION (hole).
4// Controls first, so a FAIL row is a named gap and not a broken probe.
