- Around line 830-906: Add corresponding Expr::SuperCallSpread handling in the

AsyncResource, so synthesized super(...args) invokes each required subclass
initializer instead of js_super_construct_apply. Reuse the direct-super
initialization behavior, including argument evaluation, first/second-value
defaults, derived-this binding, and field initialization.
- Around line 830-842: Update the EventEmitterAsyncResource subclass
initialization paths in lower_event_emitter_async_resource_subclass_init and the
corresponding type-value handling so each lowered argument is stored in a rooted
operand scope before lowering later arguments. Re-read the rooted options and
type_value immediately before the runtime initialization call, ensuring their
root stores dominate every potentially collecting lower_expr operation.

- Around line 547-555: Register js_event_emitter_async_resource_call and
js_event_emitter_async_resource_subclass_init with

preserve one-shot listener behavior by routing each to a one-shot runtime entry
or passing an explicit one-shot flag; ensure both no longer share the on ABI
without mode information.

- Around line 240-272: Update events_on_queue_listener to check the
EVENTS_ON_DONE flag before buffering or resolving events, returning immediately
once iteration is closed. Update events_on_return to detach listeners for
EventTarget, Stream, NetSocket, and NativeHandle targets using the same cleanup
pattern as events_on_abort_listener, while preserving the existing EventEmitter
cleanup.
In `@crates/perry-ext-events/src/module_on.rs`:
- Around line 49-56: Update the EventHelperTarget::NetSocket branch to obtain
the listener value from listener_root.get() rather than the unrooted listener
pointer before calling call_net_socket_method, matching the rooted reads used by
the sibling branches.
In `@crates/perry-ext-http/src/server/server.rs`:
- Around line 779-780: Update the listen setup flow after
js_async_hooks_provider_init so every failure return destroys server_async_id
before returning, or defer provider initialization until setup succeeds.
Preserve the existing successful-listen behavior while ensuring no initialized
provider resource lacks a matching destroy event.

- Around line 1431-1436: Update the ZlibEvent::OneShotCallback handler to remove
the initial js_async_hooks_provider_enter and js_async_hooks_provider_leave
pair, preserving only the pair that surrounds call_one_shot_callback.
- Around line 69-71: Add the js_async_hooks_provider_destroy binding alongside
the existing async-hooks declarations, then call it when stream state is removed
on both End and Error paths and after the OneShotCallback callback completes.
Use each operation’s provider ID and preserve the existing cleanup flow.
In `@crates/perry-runtime/src/async_context.rs`:
- Around line 307-319: Update the exit/disable handling around ACTIVE_CONTEXT
and HANDLE_GENERATIONS so disable() called within AsyncLocalStorage.exit()
invalidates the saved RestoreStores payload even after take_store() removes the
active entry. Treat the temporarily exited matching store as active for
generation invalidation, or directly invalidate matching pending RestoreStores
entries, while preserving normal restoration for stores that were not disabled.
In `@crates/perry-runtime/src/async_hooks.rs`:
- Around line 606-644: Update the hook delivery flow around the rooted callback
loop and HOOK_CALLBACK_DEPTH cleanup to execute callbacks through
crate::exception::js_call_catching, ensuring depth decrement and pending
PENDING_HOOK_STATES application occur on both success and thrown-exception
paths. After restoring state and applying set_hook_enabled updates, rethrow the
captured exception so existing error behavior is preserved.
In `@crates/perry-runtime/src/fs/dir_glob_watch/watch.rs`:
- Line 1533: Update js_fs_watch_file and WatchFileState to retain the resource
ID returned by init_resource("STATWATCHER", ...), then update
close_watch_file_state to call async_hooks::destroy with that ID when the
watcher is removed, mirroring the existing FsWatchState/FSEVENTWRAP lifecycle.
In `@crates/perry-runtime/src/node_stream_constructors/builders.rs`:
- Around line 128-142: Root the resolved name value immediately after the
undefined-name fallback in the builder containing js_async_resource_new, since
subsequent allocation may collect it. Use the established root-store mechanism,
reload the rooted value before passing it to js_async_resource_new, and preserve
the existing options handling.
In `@crates/perry-runtime/src/node_stream_constructors/pipeline.rs`:
- Around line 224-229: Update the completion-listener setup in the
cleanup-enabled path so options.cleanup does not register both the default
listener and the additional listener near line 237. Ensure exactly one listener
invokes callback for the first terminal event, while preserving the existing
behavior for paths without cleanup.
In `@crates/perry-runtime/src/node_stream_dispatch.rs`:
- Around line 265-283: Update event_emitter_async_resource_backing and the
affected functions in the 355–442 region to use RuntimeHandleScope for every
live receiver, key, object/prototype value, this_value, and closure that may
survive allocation. Root each value before any collecting operation, then reload
it from its handle before subsequent field access or setter calls, including the
hidden_key value before js_object_get_field_by_name_f64 and closures before
later stores.
In `@crates/perry-runtime/src/node_submodules/fs_promises.rs`:
- Around line 131-143: Root the filesystem handles across all potentially
allocating calls: in the open-file flow around promise_value_fs and
init_resource, root handle before the first call and reload it before the
second; in the directory flow around init_resource and promise_value_fs, apply
the same ordering to directory. Update both affected sites in
crates/perry-runtime/src/node_submodules/fs_promises.rs (lines 131-143 and
400-406).
In `@crates/perry-runtime/src/object/instanceof.rs`:
- Around line 341-368: Replace both raw address comparisons guarding
ordinary_has_instance_prototype_walk in the AsyncResource and AsyncLocalStorage
branches with crate::value::addr_class::is_plausible_heap_addr(raw). Preserve
the existing fallback logic and dispatch behavior while ensuring prototype
traversal only occurs for plausibly valid heap addresses.
In `@crates/perry-runtime/src/object/native_module_dispatch/dispatch_a_c.rs`:
- Around line 156-160: In the constructor-without-new error path, update the
handling around js_string_from_bytes and js_typeerror_new to create a
RuntimeHandleScope and root msg before constructing the TypeError. Ensure the
root store dominates every subsequent allocation or collection-capable call,
while preserving the existing thrown TypeError behavior.
In `@crates/perry-runtime/src/object/native_module/async_hooks_exports.rs`:
- Around line 55-78: In the async resource dispatch flow, root the materialized
args before resolving the receiver handle: update the ordering around
receiver_raw, args, and try_async_resource_method_dispatch so any
js_string_from_bytes or arena_alloc_gc activity cannot move values while the
unscanned Vec<f64> is referenced by args.as_ptr(). Preserve the existing
argument materialization and dispatch behavior.
In `@crates/perry-runtime/src/promise/assimilate.rs`:
- Around line 279-282: In the promise assimilation flow, update the code around
capture_context() to root outer before the call can collect, then reload outer
from that rooted handle before reading async_id and trigger_async_id. Ensure the
rooted store dominates both dereferences and preserve the existing ID values and
callback behavior.
In `@crates/perry-runtime/src/promise/async_step.rs`:
- Around line 671-679: Reload the promise pointer local from next_handle
immediately after init_resource_with_trigger returns, before constructing or
storing Task::AsyncStep; update the initialization path around
init_resource_with_trigger so the later next value is current rather than the
stale raw pointer.
In `@crates/perry-runtime/src/promise/microtasks.rs`:
- Around line 747-748: Update the null-step handling in the Task::AsyncStep path
used by finally_passthrough_fulfill and finally_passthrough_reject to emit
before_promise and after_promise lifecycle hooks using step_async_id and
step_trigger_id. Bracket the branch’s resolution or rejection of next with these
hooks before it exits, while preserving existing behavior for non-null steps.
- Around line 417-425: In crates/perry-runtime/src/promise/microtasks.rs lines
417-425, reload promise and value from task_promise_handle and task_value_handle
after before_promise and before calling js_promise_resolve or js_promise_reject;
update the propagation to use those reloaded values. In lines 597-668, reload
next from next_handle after each async-hooks callback and before propagation or
promise_hook_before, using the refreshed handle-backed value throughout.
In `@crates/perry-runtime/src/promise/then.rs`:
- Around line 1770-1771: The finally passthrough handlers must reload the
captured promise after capture_context() before accessing it. In
crates/perry-runtime/src/promise/then.rs lines 1770-1771, root and reload next
before creating the fulfilled propagation task; apply the same root-and-reload
change at lines 1798-1799 before creating the rejected propagation task.
In `@crates/perry-runtime/src/proxy.rs`:
- Around line 1092-1095: In the proxy setter path around key_to_rust_string and
handle_expando_set, root the incoming value before coercing the key so any GC
movement during key conversion cannot invalidate it; pass the rooted value to
handle_expando_set while preserving the existing failure return for invalid
keys.
In `@crates/perry-runtime/src/timer.rs`:
- Around line 423-424: Bound the growth of TIMER_HANDLE_KINDS used by
record_timer_handle_kind, matching the existing insert_bounded approach and
capacity pattern used by TIMER_REF_STATES; alternatively, remove entries when
timers are cleared and after non-interval timers fire for the final time.
Preserve callback-kind lookup behavior for active timers.
In `@crates/perry-stdlib/src/async_local_storage.rs`:
- Around line 86-160: Update throw_invalid_receiver,
resolve_async_local_storage_handle, and js_async_local_storage_subclass_init to
root GC-managed values such as msg, the receiver, backing values, and every
generated key in RuntimeHandleScope before any operation that may allocate.
Derive raw receiver pointers only after the relevant allocations from the rooted
receiver, then perform lookups or writes through those refreshed pointers.
In `@crates/perry-stdlib/src/common/dispatch/emitter_als.rs`:
- Around line 74-88: Update the argument handling in the dispatch path around
dispatch_async_local_storage_method so rest, receiver_raw, and forwarded values
remain in GC roots for the entire dispatch, including allocations performed by
run and exit. Replace the unrooted Vec<f64> live argument store with the
existing rooted argument representation or root the copied values before
dispatch, ensuring any collector-updated pointers are used afterward.
In `@crates/perry-stdlib/src/tls/event_pump.rs`:
- Around line 82-136: Update the affected event arms in the event-pump dispatch
function—ServerError, ServerTlsClientError, SocketData, and SocketError—to
create a RuntimeHandleScope, root each constructed value and every listener
callback pointer before iterating, and reload both values and callback pointers
immediately before each js_closure_call*. Preserve the existing event names,
callback arguments, once-listener draining, and socket cleanup behavior.
In `@crates/perry-stdlib/src/webcrypto/digest.rs`:
- Line 63: Update the digest function around the HASHREQUEST scheduling call to
root promise_val in a RuntimeHandleScope before schedule_native_callback,
ensuring the root store dominates that potentially collecting operation. After
scheduling, reload the Promise pointer from the handle before returning it,
preserving the existing callback behavior.
In `@crates/perry-stdlib/src/zlib.rs`:
- Around line 1404-1406: Remove the redundant run_resource_scope call from the
ZlibEvent::OneShotCallback branch, leaving the real enter_resource_scope
invocation so each one-shot completion emits only one before/after hook pair.

Minor comments:
In `@crates/perry-codegen/src/lower_call/builtin.rs`:
- Around line 144-160: Update the Resolver constructor lowering to capture the
first options argument with adopt_optional_arg, still lower later arguments for
side effects, then pass the retained value through the existing NaN-boxed
varargs buffer instead of zero. Update js_dns_resolver_new and
js_dns_promises_resolver_new to parse that argument and retain both timeout and
tries options, preserving the DOUBLE NaN-boxed-pointer return type.
In `@crates/perry-ext-events/src/tests.rs`:
- Around line 18-24: Replace the process-wide PERRY_GC_FORCE_EVACUATE
environment-variable mutation in GcTestGuard with a runtime-settable
configuration API, or enforce single-threaded execution for every test in this
crate so no concurrent runtime getenv can occur. Update both the set and cleanup
paths and revise the SAFETY comment to describe the guarantee actually enforced.
In `@crates/perry-stdlib/src/webcrypto/hmac.rs`:
- Line 434: Update the verification failure returns in the relevant HMAC/KMAC
paths, including zero-length KMAC output and signature-parse failures, to call
resolve_with_bool_provider(false, "SIGNREQUEST") instead of
resolve_with_bool(false). Ensure every false verification completion uses the
SIGNREQUEST provider lifecycle, while preserving the existing success path.
In `@crates/perry-stdlib/src/worker_threads/worker_pump.rs`:
- Around line 240-242: The worker event dispatch in the async resource scope
loop must enter only the resource owning the event: use MESSAGEPORT for
online/message events and WORKER for exit, rather than nesting all
async_resources. Root object_bits, callbacks, and arg before invoking the
scope’s before hooks, and add parity tests covering async IDs and hook ordering.
In `@crates/perry/src/commands/compile/build_cache.rs`:
- Around line 52-54: Remove the duplicate cache inventory entries for
PERRY_CONST_ARRAY_DESCRIPTOR and PERRY_DIALECT_DUMP, retaining exactly one
occurrence of each in the cache-variable list used by current_env().
In `@scripts/thread_local_cold_allowlist.json`:
- Line 3: Regenerate the thread-local inventory using
scripts/check_thread_locals.py with the update option so _hot_declarations and
the listed files, including callbacks.rs, match the source declarations; review
and retain only the expected generated changes.

Nitpick comments:
In `@crates/perry-runtime/src/child_process/reactor.rs`:
- Around line 1627-1642: Update cp_async_scope_for_target to ignore the null
placeholder at pipe_bits[0] when searching for a matching target, so a null
target cannot resolve to the stdin pipe scope; only match entries representing
real objects and preserve the existing child-process and pipe scope returns.

🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win
Keep the finish callback snapshot GC-safe during dispatch.
listeners_for returns copied raw closure addresses. If the first finish callback collects, the GC updates statics().listeners but cannot rewrite cb values in this local vector. A later callback can then dereference a stale closure address.
Use a mutable rooted dispatch frame for the snapshot before the first call0(). As per coding guidelines, “A GC-managed value's root store must dominate every subsequent site that can collect.”

🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win
Root namespace before the key-string allocation.
js_object_alloc_null_proto returns a raw *mut ObjectHeader. The next line calls js_string_from_bytes, which can allocate and move the new object. js_object_set_field_by_name then dereferences the stale address. timer_constructor_value in crates/perry-runtime/src/timer.rs (Lines 617-637) shows the required shape: root the object and the key, then reload both inside with_mut_ptr.
🛡️ Proposed fix: root the object and key handles
