In `@changelog.d/9931-class-expression-typeof-self.md`:
- Around line 3-5: Update the changelog entry for the named class-expression
typeof fix to state that the AST-level unresolved-global shortcut excludes the
active class inner name, allowing lexical lowering to resolve the class binding,
and mention the HIR regression test as validation.

The
node-suite/globals/class-expression-var-valueparity row returned"undefined"fortypeof linsidevar B = class l { ... }. The class uses a synthetic registry key because its inner and outer names differ, so the AST-leveltypeofshortcut misclassifiedlas an unresolved global before ordinary identifier lowering could resolve the class body's lexical binding.Keep active class inner names out of the unresolved-global shortcut and add an HIR regression that verifies the method body contains a class reference rather than
js_global_get_optional. This advances #9202 by moving that row from parity failure to 1/1 PASS.Validation:
cargo test -p perry-hir(all tests passed; existing ignores only)./run_parity_tests.sh --suite node-suite --module globals --filter class-expression-var-value(1/1 PASS)./scripts/run_lint_gates.sh(all 64 gates passed; 2 CI-only commands skipped locally)Summary by CodeRabbit
