`scripts/gc_store_site_inventory.py` flagged the new fixture's `std::ptr::write` of a `TypedArrayHeader` as an unaudited raw slot write. Classify it POINTER_FREE: the header is length/capacity/kind/elem_size/_pad numerics with no pointer field, and the destination is the test's own private anonymous mmap page rather than arena-managed memory, so the store creates no heap edge.

The Symbol-preserving rewrite read its rooted receivers back out with 24 bare
`get_raw_{const,mut}_ptr` calls, pushing `object/delete_rest.rs` to 26 sites
against its ceiling of 2.
Convert every one instead of raising the ceiling. The argument-position reads
become `with_{const,mut}_ptr`, so each pointer is derived at the call it feeds
and never outlives it; the exclude scans hoist one scoped read over a loop that
cannot collect (`js_array_get` and `js_string_key_matches_bytes` are pure
reads). `copy_rest_symbol_properties` gains a `src_boxed()` closure that
re-derives the NaN-boxed receiver from the root, so `own_symbol_slot`,
`symbol_property_is_enumerable` and `slot.read` no longer share one address
taken before the accessor that may collect. Both `js_object_rest` returns now
take the rest object's address from `across_mut` after the symbol copy rather
than from a read that preceded it.
Behaviour is unchanged: every read moved forward to its use, none backwards.
Verified: `raw_handle_debt.py` 901/901 with 104 module ceilings, and
`--no-raise-vs origin/main` reports none raised.

… not codegen #11012's first attempt put the fix in codegen: in `try_lower_static_dispatch`, any `C.m(args)` whose class chain contained an `extends_expr` was diverted to `try_lower_closure_call_fallthrough` (read the property, then call it). That guess cannot hold, because codegen cannot know what a RUNTIME-resolved parent carries — and `class MyArr extends Array {}` takes the same dynamic-parent lowering (`Array` is not a user class, so `lookup_class` misses and `extends_expr` is captured). Every inherited Array static therefore went to a property GET whose value is still `undefined` (#7541's documented gap), and `MyArr.from([1,2,3])` became "TypeError: value is not a function". That is all four of the gap regressions CI reported: `test_gap_7541_array_subclass_inherited_statics`, `test_gap_numeric_push_guarded`, `test_gap_rest_bundle_and_map_fill` and `test_gap_packed_loop_cached_receiver` each build a `class MyArr extends Array {}` and call `MyArr.from(...)`. Revert that hunk and resolve the accessor where the edge actually exists: the runtime's class-id parent chain. `js_class_static_method_call` already walks it for static methods, static fields, native protos, constructor prototypes, Promise statics, Array-subclass statics and parent-closure props; it had no arm for a class-body `static get`, which lives in `CLASS_STATIC_ACCESSORS`. Add one, gated on a registry hit so it cannot fire where no such accessor is declared — `MyArr.from` misses it and falls through to the #7541 arm unchanged. The read delegates to `js_object_get_field_by_name_f64`, the same entry point codegen emits for `const f = C.g`, rather than calling `class_static_accessor_getter_value` directly. The getter is found on an ANCESTOR and its captures live on the per-evaluation parent class OBJECT, so handing the subclass to the accessor helper makes it the capture owner and the body reads `undefined` for every captured binding (measured: #10893's own `cache` Map). Delegating also gets own-static-field-shadows-inherited-accessor precedence right for free. Arguments and receiver are rooted across the getter, which is user JS and can collect. `crates/perry/tests/issue_10893_getter_call.rs` keeps the PR's getter rows and gains the `MyArr` control, so the codegen trade cannot be made again silently. It now builds and pins the static runtime archives (the fix is runtime-side, so without that the fixture would link a stale `.a`).

…totypes
A capture-carrying class (ClassExprFresh) materializes a distinct
prototype object per evaluation. It was never recognized by
class_id_for_decl_prototype_object, so its vtable accessors were
invisible to getOwnPropertyDescriptor/Names and defineProperty, and
Object.defineProperties(C.prototype, { x: { enumerable: true } })
replaced get x/set x with a read-only undefined data property.
whatwg-url's URL does exactly that, which broke mongodb's
connection-string parsing (#11043).

The new static_accessor_call.rs read its rooted key with a bare
get_raw_const_ptr in ARGUMENT POSITION to js_object_get_field_by_name_f64,
putting one raw-handle debt site in a module with no ceiling:
raw-handle debt sites: 902 (baseline 901)
::error::per-module raw-handle rules: 1 violation(s)
.../parent_static/static_accessor_call.rs: 1 raw-handle debt site(s)
in a module with no ceiling
across_* cannot convert an argument-position read, so the fix is
with_const_ptr, which exists for exactly this: a scoped pointer handed
to a self-rooting runtime entry point. Same idiom as
util_promisify.rs:824. No ceiling raised, no allowlist entry.
raw-handle debt sites: 901 (baseline 901)

…ckages
Node builtin named re-exports (export { x } from "node:m") got a
synthetic native import + getter-backed export (#10802/#10867) so
codegen never expects a local function body for the forwarded name.
That fix scoped itself to is_node_core_module sources only.
A Perry-native npm package that is not a Node builtin (ws, same shape
applies to ioredis, mysql2, ...) re-exported the same way still fell
through to the generic Export::ReExport path, which has no compiled
source module to follow for a natively-intercepted package either.
Referencing the forwarded binding as a value inside a closure then
link-failed on an undefined __perry_wrap_perry_fn_<mod>__<name>
symbol.
This is ethers' src.ts/providers/ws.ts (export { WebSocket } from
"ws";), imported renamed by provider-websocket.ts and referenced
inside a closure.
Broaden the HIR-lowering re-export synthesis from is_node_core_module
to any perry_hir::is_native_module source (the named-export existence
check stays node-core-only, since the manifest is exhaustive only
there), and drop the matching is_node_core_module restriction on the
three codegen/driver sites that key off the same Import+Export shape
-- import.is_native alone is what discriminates "codegen must emit a
getter" from "a real compiled function body exists".
(cherry picked from commit 5924100)
…st gap origin/main's b8c2457 already fixed the #11044 ws.ts crash by broadening `import.is_native` at the three codegen/driver sites and applying the synthetic-import treatment to any native module in module_decl.rs. It left `module_has_public_named_export`'s existence check unconditional for every native module, though, not just node-core ones -- the only ones its own doc comment claims complete manifest coverage for. bcrypt is a recognized NATIVE_MODULES entry with manifest rows for hash/ compare only; real bcrypt also exports genSalt, hashSync, compareSync, getRounds, none of which are registered. `export { genSalt } from "bcrypt"` through a facade module hits that unconditional check and lower_bail!s with "does not provide an export named 'genSalt'" on a plain rebase of main's fix -- a real, legitimate export rejected on a manifest coverage gap, not an actual invalid name. Add native_npm_package_export_missing_from_manifest_reexports_lower_to_synthetic_import next to node_named_export_hygiene's existing ws/crypto re-export tests. Verified directly: fails on a pristine origin/main checkout (main-latest, 9d26936) with exactly that lower_bail! message, passes on this PR's head once the existence check is scoped to is_node_core_module.

Merge Risk: 🟡 Moderate · up to This release fixes inherited error names on factory-created classes by resolving fields through the class evaluation that built each instance. The new lookup can return a value from that class's prototype before more-derived class levels are checked. Values set on a subclass prototype can therefore be shadowed, and a lookup that starts at an ancestor can return a descendant's value. That can produce wrong property values in class hierarchies, so it should be scoped to the matching class level before merging.

`util.inspect` was the one own-key consumer that did not apply
`is_internal_runtime_key`. `Object.keys`, `for…in`,
`getOwnPropertyNames`, `JSON.stringify`, `hasOwnProperty` and spread all
filter perry's hidden runtime-internal keys; inspection printed them, so
an instance of a per-evaluation class object rendered
Escaped [Error]: boom {
__perry_ctor_class_object: Escaped [Error] {
__perry_parent_class: [Function: Error] { … }
}
}
where Node prints `Escaped [Error]: boom`.
The leak pre-dates this branch — on origin/main a class expression with a
static field already reproduces it — but routing heritage-carrying class
expressions through the fresh-class path brings
`test_gap_9440_error_name_ownership`'s `escaped-dynamic` case onto it,
which turned a latent gap into a gap-suite regression.
`showHidden` deliberately still does not reveal these keys: it exposes
non-enumerable JS properties, and these are runtime bookkeeping, not
properties at all.
Pinned by `builtins::formatting::internal_key_hiding_tests` — one case
proves the enumeration prints ordinary keys, two prove the internal ones
are hidden, and each first asserts its spelling really is in the
allowlist so a renamed constant fails the precondition rather than
passing vacuously.

#11113 adds class_evaluation_prototype_class_id as the miss path of class_id_for_decl_prototype_object, and proxy::metadata's normalize_target_bits feeds that any POINTER_TAG payload it is handed — including arbitrary non-pointer bits. That made it the first caller to pass genuinely unvalidated bits to try_read_gc_header, and CI aborted: proxy::metadata::tests::unrelated_heap_pointer_passes_through_unchanged panicked at crates/perry-runtime/src/value/addr_class.rs:272: misaligned pointer dereference: address must be a multiple of 0x4 but is 0xabcde7 thread caused non-unwinding panic. aborting. A non-unwinding abort takes the whole test binary down, so cargo-test reported only that, not a test failure. The gap is in the predicate, not the caller. is_plausible_heap_addr is two magnitude checks with no alignment test, so it admits IN-RANGE garbage like 0xABCDEF — while try_read_gc_header's own doc already promises to return None "without touching memory for ... out-of-range garbage". try_read_tracked_gc_header has always checked alignment (addr_class.rs:390); this function simply never did. A GC allocation's user address is always align_of::<GcHeader>()-aligned (GC_HEADER_SIZE is a multiple of it), so the check cannot exclude a real object — it can only turn would-be-UB into None. One AND on a path that then dereferences. Fixed at the predicate rather than at #11113's call site so every other caller is covered too.

Scope the pinned-class fast path to the matching class level.
The pinned path runs before the class_id walk and returns from the pinned class object's prototype. This can skip more-derived declaration and synthetic prototype levels. It also resolves from a more-derived prototype when the caller starts at an ancestor class_id.
Compute the pin before the loop, but apply it only when js_object_get_class_id(pin_obj) == cid. Continue the existing prototype walk for other class levels.
