In `@crates/perry-hir/src/lower/lower_module_fn.rs`:
- Around line 43-74: Update the Stmt::Labeled reflection handling so that when
expansion produces leading statements followed by a For, the leading statements
are appended to reflected and the label is attached to the final For statement
rather than wrapping the sequence in DoWhile(false). Preserve the existing
behavior for single statements and other multi-statement expansions, ensuring
continue targets the original loop.
In `@crates/perry-runtime/src/object/class_registry/prototype_objects.rs`:
- Around line 66-72: Root the parent values before each
object_set_static_prototype call, using RuntimeHandleScope, and reload the
rooted NaN-boxed bits inside the with_mut_ptr callback before invoking the
setter. Apply this in
crates/perry-runtime/src/object/class_registry/prototype_objects.rs:66-72 for
object_proto_bits and
crates/perry-runtime/src/object/global_this/generator.rs:153-159 for
function_proto; both sites require the direct rooting change.
In `@crates/perry-runtime/src/typedarray/construct.rs`:
- Around line 450-456: Update the typed-array construction loop around
js_array_get_f64 to pass the original array-like receiver through prototype
lookup, so inherited indexed accessors execute with that receiver as this while
preserving throw propagation. Add a regression test covering an inherited
indexed accessor and verifying its receiver.

In `@crates/perry-hir/src/lower/lower_module_fn.rs`:
- Around line 58-77: Update the for-loop update rewriting around the existing
update-expression handling so each LocalSet and Update is followed immediately
by its corresponding globalThis property write, preserving expression evaluation
order. Replace the current end-of-expression global mirroring built in the
updated_globals sequence, and add a regression covering a later expression such
as observe(globalThis.i) reading the newly updated value.
In `@crates/perry-runtime/src/array/indexing.rs`:
- Around line 356-377: Root the GC-managed receiver before any prototype lookup
or getter call that may collect. In
crates/perry-runtime/src/array/indexing.rs:356-377, register arr and keep the
root live through array_inherited_index_get and
sort_object_prototype_index_get_with_receiver; in
crates/perry-runtime/src/array/sort.rs:363-373, register the supplied receiver
before lookup and getter invocation. Use the existing runtime rooting mechanism
and ensure the root dominates every affected call.
In `@test-files/test_issue_611_globalthis.ts`:
- Around line 49-53: Wrap the body of case 1 in the switch statement with braces
to satisfy lint/correctness/noSwitchDeclarations, while preserving the
switchScriptVar var declaration and its script-scoped binding.

- Around line 158-172: Update reflect_script_var_update_parts to recursively
traverse child expressions for non-sequence nodes, preserving evaluation order
and each expression’s result value while mirroring nested LocalSet and Update
nodes. Ensure nested assignments or updates inside call arguments are reflected
before later arguments read the corresponding script variable, and add a
regression test covering this case.
In `@crates/perry-runtime/src/object/class_registry/construct.rs`:
- Around line 1252-1260: Restrict the native extends acceptance branch around
is_bound_native_method_closure_value to only allow exports identified as
constructable by the constructor registry or equivalent constructor-specific
metadata. Ensure non-constructable bound exports such as repl.start and
events.init still trigger the required TypeError, and add a regression test
covering class inheritance from one of these exports.

…ape guards (#8682) Lands three reviewed PRs as one squash: #8674, #8675, #8676. - #8674: compress array forwarding chains (`clean_arr_ptr` multi-hop walk). - #8675: share numeric guards across dynamic add trees. - #8676: pack monomorphic method shape guards. These three were authored as a stack on top of #8672, but their contents touch disjoint files, so they are cherry-picked onto main on their own. #8672 is NOT included: it defines its own `is_bound_native_method_closure_value` (true for any bound native-module export with a non-empty module name), which #8662 superseded on main with the strictly narrower `is_bound_native_constructor_closure_value` (gated on explicit constructor metadata). Those predicates have different truth sets, so the substitution is a behavioural change at every call site and is left to the author to rebase. Also splits `array/tests.rs`, which #8674 pushed over the 2000-line cap, into an `array/forwarding_tests.rs` sibling. Pure relocation. Version bump not included per maintainer policy.
