…e message
An fs error's code/errno/syscall/path lived in six side tables keyed by
the MESSAGE STRING's address. Two consequences, both fixed here.
WRONG ERROR. Any `new Error(m)` built from the same message text picked
up the unrelated fs error's fields:
new Error(fsErr.message).code // ENOENT, node says undefined
.syscall / .errno / .path // stat / -2 / the path
The metadata belonged to the string, so anything holding that string
answered to it.
INVISIBLE TO REFLECTION. In node these are ordinary own properties.
Served from a side table behind property getters they were absent from
every enumeration path:
Object.keys(e) [] -> code,errno,path,syscall
hasOwnProperty('code') false -> true
getOwnPropertyDescriptor undefined -> {value,writable,enumerable,configurable}
JSON.stringify(e) {} -> {"errno":-2,"code":"ENOENT",...}
{...e} {} -> same
Any code logging or serialising a caught fs error lost its whole payload.
Three sites each held a different wrong assumption about errors:
* the fs builders keyed on the message string;
* JSON.stringify hardcoded "{}" for GC_TYPE_ERROR — right for a plain
error (message/name/stack are non-enumerable), wrong once the error
has enumerable own props, so it also dropped user-assigned ones;
* Object.assign/spread had no Error arm, so it copied nothing.
All three now enumerate through exotic_own_keys(.., enumerable_only),
the same enumeration Object.keys uses, so they cannot drift apart.
ORDER. ERROR_USER_PROPS was a HashMap with an alphabetical sort_by for
determinism — stable but not node's. It is insertion-ordered now, with
reassignment keeping a key's original position, and the fs fields are
installed in node's uvException order (errno, code, syscall, path, dest).
The GC root scanner over these props moved to the ordered store.
Verified against node on the claude-code host: three repro programs are
byte-identical including key order. Suite 2746 passed.
… tier An erased Array declaration admits object-backed Array subclasses (`class Archetype extends Array`) and typed arrays as readily as plain Arrays. The canonical-i32 read split (#8872) committed such a receiver's integer keys to the guarded plain-array tier, whose feedback fallback classifies the receiver out of line on every read; wolf-ecs `packed[sparse[x]]` paid 4-6% of both benchmarks there even after the fallback learned the dense subclass read. The element arm of a claimed-receiver site now reads the GcHeader type byte once: a plain Array keeps the guarded tier, every other heap pointer takes the receiver-unknown numeric tiers (inline typed-array read, dense subclass `arrlike.ic`, complete dispatcher) that the runtime-key arm of the same site already uses, and non-pointers keep the guarded tier's unchanged fallback. Test: `index_get_claim_tests::claimed_array_receiver_brands_before_committing_a_canonical_key_to_the_plain_tier`. Claude-Session: https://claude.ai/code/session_019WVcWKmYsUBnnFB7nBgbBJ (cherry picked from commit 8819e362356139322bddb6b2c1734637630bb24d)
…ssification `js_gc_note_slot_layout_aware` returns without acting when the old and new slot values share a pointer classification, unless both are pointers and the array carries an element-shape proof (`GC_ARRAY_ELEMENT_SHAPE`). The guarded in-bounds store fast arm still paid the call on every store — 4% of the wolf-ecs add/remove profile, almost all of it `ents[id] = arch` pointer-over- pointer stores into proof-free arrays. The fast arm now stores through a deferred-note variant of the shared slot emitter (old bits loaded, string-addref demote unchanged), classifies both values with an exact codegen mirror of `layout_pointer_bearing_bits`, tests the element-shape bit on the `_reserved` word `deref.live` already loaded, and calls the note only from a gated `laynote` block when it has work: a classification change (which must reach `layout_note_slot`) or a pointer- over-pointer store into a proof-bearing array. Test: `index_set_barrier_tests::the_fast_arm_layout_note_is_gated_on_the_pointer_classification_and_shape_bit`. Claude-Session: https://claude.ai/code/session_019WVcWKmYsUBnnFB7nBgbBJ

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not bypass prototype-index invalidation.
try_strict_dense_number_store does not check PERRY_ARRAY_INDEX_FAST_PATH_INVALIDATED and accepts an in-range hole. After an indexed accessor is installed on Array.prototype, assignment to a hole must use the prototype setter or throw. This lane writes the slot directly and skips that behavior.
Reject this lane when the global invalidation flag is set, as try_strict_dense_index_set already does.

Correct the documented Error key order.
The stated Object.keys order conflicts with attach_fs_error_props and the diagnostics order test, which use errno, code, syscall, path.

These new paths retain managed Error pointers in raw locals while property-string allocation, accessor execution, assignment, or recursive serialization can collect. A moving collection can make later side-table lookups, receivers, or return values stale.

Preserve canonical index-key order.
value_keys(ExoticKind::Error, ...) returns insertion order directly, and exotic_own_keys passes it to Object.keys and stringify_error_own_props without reordering. Keys such as "2" and "1" can therefore enumerate in the wrong order. Apply canonical array-index ordering before returning Error keys.
