+# Deferring the finalizer drain out of the GC epilogue
+
+Status: **DEFERRED** — not implemented. The husk-hardening (`tns::GetValueOrReport`) and
+the `IterateFinalizerHandlesAsRoots` pending-bit guard were prioritized instead as the
+likely fixes for the field crash (BLACKOUT-V3-IOS-41/42,
+`ConcurrentMarkingVisitor::RecordSlot` / `MainMarkingVisitor::RecordSlot`, fault addresses
+all `<256 KiB page base> | 1`). This note records the design and its constraints for when
+the drain move is picked up.
+
+Background: [docs/knowledge/v8-resurrecting-finalizers.md](docs/knowledge/v8-resurrecting-finalizers.md).
+Today `GlobalHandles::InvokeFinalizerCallbacks()` runs inside the GC epilogue
+(`PostGarbageCollectionProcessing`), under an `AllowJavascriptExecution` lift, because
+finalizers re-enter JS (`DisposeValue` → `-dealloc` → JS overrides). The proposal was to
+run the drain from a posted foreground task instead, deleting the lift and the whole
+"JS + nested GC inside `Heap::CollectGarbage`" hazard class.
+
+## Why it was deferred: "cycles are resolved by early release"
+
+The concern: JS↔ObjC cycles (wrapper W owns native N; N natively retains a JS-backed
+object that leads back to W) only collect because disposal is driven by **native retain
+count**, not JS reachability — W's finalizer releases N even though surviving JS may still
+reach W, and the release cascade is what unwinds the cycle.
+
+**Analysis: deferral does not change those semantics.** The same callbacks make the same
+protect/release decisions; only *when* they run changes. A deferred drain still releases
+N, N's dealloc still drops its retains, and the next GC still queues the newly
+unprotected handles. Cycle resolution is latency-shifted (one runloop turn per cascade
+step, worst case), not broken.
+
+What genuinely depends on the drain being synchronous with the GC is **promptness**, in
+exactly two scenarios:
+
+1. **Memory pressure.** `Heap::CollectAllAvailableGarbage` loops up to 7 attempts until
+   nothing more frees. With the epilogue drain, each round's finalizers release native
+   memory *inside the loop*, so round N+1 reclaims what round N unblocked. Deferred,
+   every pending finalizer is a strong root, rounds 2–7 free nothing native, and no
+   native memory is released until the runloop turns — under a jetsam-adjacent memory
+   warning that latency can kill the process.
+2. **Long synchronous JS.** Allocation-pressure full GCs during a heavy synchronous
+   stretch never reach the runloop; pending finalizers pile up as strong roots and
+   interop temporaries are unreclaimable until the JS yields.
+
+Steady-state disposal latency (one extra turn) is invisible.
+
+## The design to revisit: hybrid, mirroring upstream
+
+V8 already encodes this exact trade-off for second-pass phantom callbacks, ten lines
+below our drain (`global-handles.cc:1002` @ 14.9.207.39):
+
+```cpp
+const bool synchronous_second_pass =
+    isolate_->MemorySaverModeEnabled() || v8_flags.predictable ||
+    isolate_->heap()->IsTearingDown() ||
+    (gc_callback_flags &
+     (kGCCallbackFlagForced | kGCCallbackFlagCollectAllAvailableGarbage |
+      kGCCallbackFlagSynchronousPhantomCallbackProcessing)) != 0;
+```
+
+Mirror it for the finalizer drain:
+
+- **Default: defer** to a posted foreground task. The drain then runs in an ordinary JS
+  context — no `AllowJavascriptExecution` lift, no nested-GC-inside-the-epilogue.
+- **Synchronous (keeping the lift) only when V8 itself goes synchronous**:
+  `kGCCallbackFlagCollectAllAvailableGarbage`, teardown, and *debatably*
+  `kGCCallbackFlagForced`.
+
+### Caveats
+
+- **`gc()` always passes `kGCCallbackFlagForced`** (`gc-extension.cc:204`), and the
+  Blackout app currently calls `gc()` from a timer (`Utils.queueGC`) — every crash stack
+  in the field goes through `GCExtension::GC`. If plain Forced stays on the synchronous
+  path, the hazardous epilogue drain remains the *hot* path in production. Either exclude
+  plain Forced from the sync set (a `gc()` caller cannot observe native release
+  synchronously anyway — nothing reachable from JS dies), or pair the change with
+  removing the app-side `gc()` timer.
+- **Scenario 2 (sync-JS starvation) needs its own trigger** if it matters in practice:
+  `Isolate::RequestInterrupt` fires at JS safepoints on the JS thread, where JS execution
+  is legal (the inspector's pause-on-interrupt runs a nested message loop from there).
+  Post a task *and* an interrupt; whichever fires first drains. Needs separate
+  validation: stack-depth headroom for `-dealloc` → JS chains, reentrancy. Follow-up,
+  not a blocker.
+- **The `IterateFinalizerHandlesAsRoots()` pending-bit guard is load-bearing here, not
+  hardening.** Deferral widens the window between queueing and draining to a full
+  runloop turn of arbitrary JS; any GC in that window iterates `pending_finalizers_`
+  and must skip entries whose bit was cleared (freed or re-armed nodes). The patch
+  already skips and compacts stale entries — keep that behaviour when reworking the
+  drain.
+- **Teardown** needs a synchronous final drain (`~Runtime` / `DisposeAllRegistered`).
+- Ordering relative to second-pass callbacks and Heap epilogue callbacks changes;
+  nothing known to depend on it, but re-check when implementing.
+
+## What this does NOT fix
+
+- The **husk hazard** (a finalized object outliving its native half — the n1→n2 pair in
+  the knowledge doc). That is created at `IdentifyDeadFinalizerHandles()` snapshot time,
+  before any drain, and is unaffected by drain timing. The checked-accessor hardening in
+  the runtime is the fix for that, and is the prime suspect for the field crash.
+- Anything the reachability redesign
+  ([RESURRECTION_TO_REACHABILITY.md](RESURRECTION_TO_REACHABILITY.md)) addresses. That
+  remains the endgame — tracing collects cycles without early release at all — and this
+  hybrid is compatible scaffolding until then.
+
+## Validation plan when picked up
+
+1. TestRunner suite green with the drain deferred (default path).
+2. A memory-pressure test: allocate wrapper-heavy garbage, trigger
+   `CollectAllAvailableGarbage` (low-memory notification), assert native memory is
+   reclaimed without a runloop turn.
+3. Worker teardown specs (synchronous final drain).
+4. Soak on a checked V8 build (`dcheck_always_on=true v8_enable_verify_heap=true`) with
+   `--verify-heap --stress-incremental-marking --stress-concurrent-marking`.

+
+      "Derivative Works" shall mean any work, whether in Source or Object

+
+      "Contribution" shall mean any work of authorship, including

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+/**
+ * @file ada.h
+ * @brief Main header for the Ada URL parser library.
+ *
+ * This is the primary entry point for the Ada URL parser library. Including
+ * this single header provides access to the complete Ada API, including:
+ *
+ * - URL parsing via `ada::parse()` function
+ * - Two URL representations: `ada::url` and `ada::url_aggregator`
+ * - URL search parameters via `ada::url_search_params`
+ * - URL pattern matching via `ada::url_pattern` (URLPattern API)
+ * - IDNA (Internationalized Domain Names) support
+ *
+ * @example
+ * ```cpp

+ * @brief URL pattern matching class implementing the URLPattern API.
+ *
+ * URLPattern provides a way to match URLs against patterns with wildcards
+ * and named capture groups. It's useful for routing, URL-based dispatching,
+ * and URL validation.
+ *
+ * Pattern syntax supports:
+ * - Literal text matching
+ * - Named groups: `:name` (matches up to the next separator)
+ * - Wildcards: `*` (matches everything)
+ * - Custom regex: `(pattern)`
+ * - Optional segments: `:name?`
+ * - Repeated segments: `:name+`, `:name*`
+ *
+ * @tparam regex_provider The regex implementation to use for pattern matching.
+ *         Must satisfy the url_pattern_regex::regex_concept.
+ *
+ * @note All string inputs must be valid UTF-8.
+ *

-# The V8 public C++ API
-
-# Overview
-
-The V8 public C++ API aims to support four use cases:
-
-1. Enable applications that embed V8 (called the embedder) to configure and run
-   one or more instances of V8.
-2. Expose ECMAScript-like capabilities to the embedder.
-3. Enable the embedder to interact with ECMAScript by exposing API objects.
-4. Provide access to the V8 debugger (inspector).
-
-# Configuring and running an instance of V8
-
-V8 requires access to certain OS-level primitives such as the ability to
-schedule work on threads, or allocate memory.
-
-The embedder can define how to access those primitives via the v8::Platform
-interface. While V8 bundles a basic implementation, embedders are highly
-encouraged to implement v8::Platform themselves.
-
-Currently, the v8::ArrayBuffer::Allocator is passed to the v8::Isolate factory
-method, however, conceptually it should also be part of the v8::Platform since
-all instances of V8 should share one allocator.
-
-Once the v8::Platform is configured, an v8::Isolate can be created. All
-further interactions with V8 should explicitly reference the v8::Isolate they
-refer to. All API methods should eventually take an v8::Isolate parameter.
-
-When a given instance of V8 is no longer needed, it can be destroyed by
-disposing the respective v8::Isolate. If the embedder wishes to free all memory
-associated with the v8::Isolate, it has to first clear all global handles
-associated with that v8::Isolate.
-
-# ECMAScript-like capabilities
-
-In general, the C++ API shouldn't enable capabilities that aren't available to
-scripts running in V8. Experience has shown that it's not possible to maintain
-such API methods in the long term. However, capabilities also available to
-scripts, i.e., ones that are defined in the ECMAScript standard are there to
-stay, and we can safely expose them to embedders.
-
-The C++ API should also be pleasant to use, and not require learning new
-paradigms. Similarly to how the API exposed to scripts aims to provide good
-ergonomics, we should aim to provide a reasonable developer experience for this
-API surface.
-
-ECMAScript makes heavy use of exceptions, however, V8's C++ code doesn't use
-C++ exceptions. Therefore, all API methods that can throw exceptions should
-indicate so by returning a v8::Maybe&lt;&gt; or v8::MaybeLocal&lt;&gt; result,
-and by taking a v8::Local&lt;v8::Context&gt; parameter that indicates in which
-context a possible exception should be thrown.
-
-# API objects
-
-V8 allows embedders to define special objects that expose additional
-capabilities and APIs to scripts. The most prominent example is exposing the
-HTML DOM in Blink. Other examples are e.g. node.js. It is less clear what kind
-of capabilities we want to expose via this API surface. As a rule of thumb, we
-want to expose operations as defined in the WebIDL and HTML spec: we
-assume that those requirements are somewhat stable, and that they are a
-superset of the requirements of other embedders including node.js.
-
-Ideally, the API surfaces defined in those specs hook into the ECMAScript spec
-which in turn guarantees long-term stability of the API.
-
-# The V8 inspector
-
-All debugging capabilities of V8 should be exposed via the inspector protocol.
-The exception to this are profiling features exposed via v8-profiler.h.
-Changes to the inspector protocol need to ensure backwards compatibility and
-commitment to maintain.

-# Oilpan: C++ Garbage Collection
-
-Oilpan is an open-source garbage collection library for C++ that can be used stand-alone or in collaboration with V8's JavaScript garbage collector.
-Oilpan implements mark-and-sweep garbage collection (GC) with limited compaction (for a subset of objects).
-
-**Key properties**
-
-- Trace-based garbage collection;
-- Incremental and concurrent marking;
-- Incremental and concurrent sweeping;
-- Precise on-heap memory layout;
-- Conservative on-stack memory layout;
-- Allows for collection with and without considering stack;
-- Non-incremental and non-concurrent compaction for selected spaces;
-
-See the [Hello World](https://chromium.googlesource.com/v8/v8/+/main/samples/cppgc/hello-world.cc) example on how to get started using Oilpan to manage C++ code.
-
-Oilpan follows V8's project organization, see e.g. on how we accept [contributions](https://v8.dev/docs/contribute) and [provide a stable API](https://v8.dev/docs/api).
-
-## Threading model
-
-Oilpan features thread-local garbage collection and assumes heaps are not shared among threads.
-In other words, objects are accessed and ultimately reclaimed by the garbage collector on the same thread that allocates them.
-This allows Oilpan to run garbage collection in parallel with mutators running in other threads.
-
-References to objects belonging to another thread's heap are modeled using cross-thread roots.
-This is even true for on-heap to on-heap references.
-
-## Heap partitioning
-
-Oilpan's heaps are partitioned into spaces.
-The space for an object is chosen depending on a number of criteria, e.g.:
-
-- Objects over 64KiB are allocated in a large object space
-- Objects can be assigned to a dedicated custom space.
-  Custom spaces can also be marked as compactable.
-- Other objects are allocated in one of the normal page spaces bucketed depending on their size.
-
-## Precise and conservative garbage collection
-
-Oilpan supports two kinds of GCs:
-
-1. **Conservative GC.**
-A GC is called conservative when it is executed while the regular native stack is not empty.
-In this case, the native stack might contain references to objects in Oilpan's heap, which should be kept alive.
-The GC scans the native stack and treats the pointers discovered via the native stack as part of the root set.
-This kind of GC is considered imprecise because values on stack other than references may accidentally appear as references to on-heap object, which means these objects will be kept alive despite being in practice unreachable from the application as an actual reference.
-
-2. **Precise GC.**
-A precise GC is triggered at the end of an event loop, which is controlled by an embedder via a platform.
-At this point, it is guaranteed that there are no on-stack references pointing to Oilpan's heap.
-This means there is no risk of confusing other value types with references.
-Oilpan has precise knowledge of on-heap object layouts, and so it knows exactly where pointers lie in memory.
-Oilpan can just start marking from the regular root set and collect all garbage precisely.
-
-## Atomic, incremental and concurrent garbage collection
-
-Oilpan has three modes of operation:
-
-1. **Atomic GC.**
-The entire GC cycle, including all its phases (e.g. see [Marking](#Marking-phase) and [Sweeping](#Sweeping-phase)), are executed back to back in a single pause.
-This mode of operation is also known as Stop-The-World (STW) garbage collection.
-It results in the most jank (due to a single long pause), but is overall the most efficient (e.g. no need for write barriers).
-
-2. **Incremental GC.**
-Garbage collection work is split up into multiple steps which are interleaved with the mutator, i.e. user code chunked into tasks.
-Each step is a small chunk of work that is executed either as dedicated tasks between mutator tasks or, as needed, during mutator tasks.
-Using incremental GC introduces the need for write barriers that record changes to the object graph so that a consistent state is observed and no objects are accidentally considered dead and reclaimed.
-The incremental steps are followed by a smaller atomic pause to finalize garbage collection.
-The smaller pause times, due to smaller chunks of work, helps with reducing jank.
-
-3. **Concurrent GC.**
-This is the most common type of GC.
-It builds on top of incremental GC and offloads much of the garbage collection work away from the mutator thread and on to background threads.
-Using concurrent GC allows the mutator thread to spend less time on GC and more on the actual mutator.
-
-## Marking phase
-
-The marking phase consists of the following steps:
-
-1. Mark all objects in the root set.
-
-2. Mark all objects transitively reachable from the root set by calling `Trace()` methods defined on each object.
-
-3. Clear out all weak handles to unreachable objects and run weak callbacks.
-
-The marking phase can be executed atomically in a stop-the-world manner, in which all 3 steps are executed one after the other.
-
-Alternatively, it can also be executed incrementally/concurrently.
-With incremental/concurrent marking, step 1 is executed in a short pause after which the mutator regains control.
-Step 2 is repeatedly executed in an interleaved manner with the mutator.
-When the GC is ready to finalize, i.e. step 2 is (almost) finished, another short pause is triggered in which step 2 is finished and step 3 is performed.
-
-To prevent a user-after-free (UAF) issues it is required for Oilpan to know about all edges in the object graph.
-This means that all pointers except on-stack pointers must be wrapped with Oilpan's handles (i.e., Persistent<>, Member<>, WeakMember<>).
-Raw pointers to on-heap objects create an edge that Oilpan cannot observe and cause UAF issues
-Thus, raw pointers shall not be used to reference on-heap objects (except for raw pointers on native stacks).
-
-## Sweeping phase
-
-The sweeping phase consists of the following steps:
-
-1. Invoke pre-finalizers.
-At this point, no destructors have been invoked and no memory has been reclaimed.
-Pre-finalizers are allowed to access any other on-heap objects, even those that may get destructed.
-
-2. Sweeping invokes destructors of the dead (unreachable) objects and reclaims memory to be reused by future allocations.
-
-Assumptions should not be made about the order and the timing of their execution.
-There is no guarantee on the order in which the destructors are invoked.
-That's why destructors must not access any other on-heap objects (which might have already been destructed).
-If some destructor unavoidably needs to access other on-heap objects, it will have to be converted to a pre-finalizer.
-The pre-finalizer is allowed to access other on-heap objects.
-
-The mutator is resumed before all destructors have ran.
-For example, imagine a case where X is a client of Y, and Y holds a list of clients.
-If the code relies on X's destructor removing X from the list, there is a risk that Y iterates the list and calls some method of X which may touch other on-heap objects.
-This causes a use-after-free.
-Care must be taken to make sure that X is explicitly removed from the list before the mutator resumes its execution in a way that doesn't rely on X's destructor (e.g. a pre-finalizer).
-
-Similar to marking, sweeping can be executed in either an atomic stop-the-world manner or incrementally/concurrently.
-With incremental/concurrent sweeping, step 2 is interleaved with mutator.
-Incremental/concurrent sweeping can be atomically finalized in case it is needed to trigger another GC cycle.
-Even with concurrent sweeping, destructors are guaranteed to run on the thread the object has been allocated on to preserve C++ semantics.
-
-Notes:
-
-* Weak processing runs only when the holder object of the WeakMember outlives the pointed object.
-If the holder object and the pointed object die at the same time, weak processing doesn't run.
-It is wrong to write code assuming that the weak processing always runs.
-
-* Pre-finalizers are heavy because the thread needs to scan all pre-finalizers at each sweeping phase to determine which pre-finalizers should be invoked (the thread needs to invoke pre-finalizers of dead objects).
-Adding pre-finalizers to frequently created objects should be avoided.

- * This file provides additional API on top of the default one for making
- * API calls, which come from embedder C++ functions. The functions are being
- * called directly from optimized code, doing all the necessary typechecks
- * in the compiler itself, instead of on the embedder side. Hence the "fast"
- * in the name. Example usage might look like:
- *
- * \code
- *    void FastMethod(int param, bool another_param);
- *
- *    v8::FunctionTemplate::New(isolate, SlowCallback, data,
- *                              signature, length, constructor_behavior
- *                              side_effect_type,
- *                              &v8::CFunction::Make(FastMethod));
- * \endcode
- *
- * By design, fast calls are limited by the following requirements, which
- * the embedder should enforce themselves:
- *   - they should not allocate on the JS heap;
- *   - they should not trigger JS execution.
- * To enforce them, the embedder could use the existing
- * v8::Isolate::DisallowJavascriptExecutionScope and a utility similar to
- * Blink's NoAllocationScope:
- * https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/platform/heap/thread_state_scopes.h;l=16
- *
- * Due to these limitations, it's not directly possible to report errors by
- * throwing a JS exception or to otherwise do an allocation. There is an
- * alternative way of creating fast calls that supports falling back to the
- * slow call and then performing the necessary allocation. When one creates
- * the fast method by using CFunction::MakeWithFallbackSupport instead of
- * CFunction::Make, the fast callback gets as last parameter an output variable,
- * through which it can request falling back to the slow call. So one might
- * declare their method like:
- *
- * \code
- *    void FastMethodWithFallback(int param, FastApiCallbackOptions& options);
- * \endcode
- *
- * If the callback wants to signal an error condition or to perform an
- * allocation, it must set options.fallback to true and do an early return from
- * the fast method. Then V8 checks the value of options.fallback and if it's
- * true, falls back to executing the SlowCallback, which is capable of reporting
- * the error (either by throwing a JS exception or logging to the console) or
- * doing the allocation. It's the embedder's responsibility to ensure that the
- * fast callback is idempotent up to the point where error and fallback
- * conditions are checked, because otherwise executing the slow callback might
- * produce visible side-effects twice.
- *
- * An example for custom embedder type support might employ a way to wrap/
- * unwrap various C++ types in JSObject instances, e.g:
- *
- * \code
- *
- *    // Helper method with a check for field count.
- *    template <typename T, int offset>
- *    inline T* GetInternalField(v8::Local<v8::Object> wrapper) {
- *      assert(offset < wrapper->InternalFieldCount());
- *      return reinterpret_cast<T*>(
- *          wrapper->GetAlignedPointerFromInternalField(offset));
- *    }
- *
- *    class CustomEmbedderType {
- *     public:
- *      // Returns the raw C object from a wrapper JS object.
- *      static CustomEmbedderType* Unwrap(v8::Local<v8::Object> wrapper) {
- *        return GetInternalField<CustomEmbedderType,
- *                                kV8EmbedderWrapperObjectIndex>(wrapper);
- *      }
- *      static void FastMethod(v8::Local<v8::Object> receiver_obj, int param) {
- *        CustomEmbedderType* receiver = static_cast<CustomEmbedderType*>(
- *          receiver_obj->GetAlignedPointerFromInternalField(
- *            kV8EmbedderWrapperObjectIndex));
- *
- *        // Type checks are already done by the optimized code.
- *        // Then call some performance-critical method like:
- *        // receiver->Method(param);
- *      }
- *
- *      static void SlowMethod(
- *          const v8::FunctionCallbackInfo<v8::Value>& info) {
- *        v8::Local<v8::Object> instance =
- *          v8::Local<v8::Object>::Cast(info.Holder());
- *        CustomEmbedderType* receiver = Unwrap(instance);
- *        // TODO: Do type checks and extract {param}.

- *        reinterpret_cast<void*>(embedder_object));
- *
- *      // TODO: Expose {object} where it's necessary.
- *    }
- * \endcode
- *
- * For instance if {object} is exposed via a global "obj" variable,
- * one could write in JS:
- *   function hot_func() {
- *     obj.method(42);
- *   }
- * and once {hot_func} gets optimized, CustomEmbedderType::FastMethod
- * will be called instead of the slow version, with the following arguments:
- *   receiver := the {embedder_object} from above
- *   param := 42
- *
- * Currently supported return types:
- *   - void
- *   - bool
- *   - int32_t
- *   - uint32_t
- *   - float32_t
- *   - float64_t
- * Currently supported argument types:
- *  - pointer to an embedder type
- *  - JavaScript array of primitive types
- *  - bool
- *  - int32_t
- *  - uint32_t
- *  - int64_t
- *  - uint64_t
- *  - float32_t
- *  - float64_t
- *
- * The 64-bit integer types currently have the IDL (unsigned) long long
- * semantics: https://heycam.github.io/webidl/#abstract-opdef-converttoint
- * In the future we'll extend the API to also provide conversions from/to
- * BigInt to preserve full precision.
- * The floating point types currently have the IDL (unrestricted) semantics,
- * which is the only one used by WebGL. We plan to add support also for
- * restricted floats/doubles, similarly to the BigInt conversion policies.
- * We also differ from the specific NaN bit pattern that WebIDL prescribes
- * (https://heycam.github.io/webidl/#es-unrestricted-float) in that Blink
- * passes NaN values as-is, i.e. doesn't normalize them.
- *
- * To be supported types:
- *  - TypedArrays and ArrayBuffers
- *  - arrays of embedder types
- *
- *
- * The API offers a limited support for function overloads:
- *
- * \code
- *    void FastMethod_2Args(int param, bool another_param);
- *    void FastMethod_3Args(int param, bool another_param, int third_param);
- *
- *    v8::CFunction fast_method_2args_c_func =
- *         MakeV8CFunction(FastMethod_2Args);
- *    v8::CFunction fast_method_3args_c_func =
- *         MakeV8CFunction(FastMethod_3Args);
- *    const v8::CFunction fast_method_overloads[] = {fast_method_2args_c_func,
- *                                                   fast_method_3args_c_func};
- *    Local<v8::FunctionTemplate> method_template =
- *        v8::FunctionTemplate::NewWithCFunctionOverloads(
- *            isolate, SlowCallback, data, signature, length,
- *            constructor_behavior, side_effect_type,
- *            {fast_method_overloads, 2});
- * \endcode
- *
- * In this example a single FunctionTemplate is associated to multiple C++
- * functions. The overload resolution is currently only based on the number of
- * arguments passed in a call. For example, if this method_template is
- * registered with a wrapper JS object as described above, a call with two
- * arguments:
- *    obj.method(42, true);
- * will result in a fast call to FastMethod_2Args, while a call with three or
- * more arguments:
- *    obj.method(42, true, 11);
- * will result in a fast call to FastMethod_3Args. Instead a call with less than
- * two arguments, like:
- *    obj.method(42);
- * would not result in a fast call but would fall back to executing the
- * associated SlowCallback.

- * An object reference managed by the v8 garbage collector.

- * collector may move objects, it is unsafe to point directly to an object.
- * Instead, all objects are stored in handles which are known by the garbage
- * collector and updated whenever an object moves.  Handles should always be
- * passed by value (except in cases like out-parameters) and they should never
- * be allocated on the heap.
- *
- * There are two types of handles: local and persistent handles.
- *
- * Local handles are light-weight and transient and typically used in local
- * operations.  They are managed by HandleScopes. That means that a HandleScope
- * must exist on the stack when they are created and that they are only valid
- * inside of the HandleScope active during their creation. For passing a local
- * handle to an outer HandleScope, an EscapableHandleScope and its Escape()
- * method must be used.
- *
- * Persistent handles can be used when storing objects across several
- * independent operations and have to be explicitly deallocated when they're no
- * longer used.
- *
- * It is safe to extract the object stored in the handle by dereferencing the
- * handle (for instance, to extract the Object* from a Local<Object>); the value
- * will still be governed by a handle behind the scenes and the same rules apply
- * to these values as to their handles.

-/**
- * Multiple threads in V8 are allowed, but only one thread at a time is allowed
- * to use any given V8 isolate, see the comments in the Isolate class. The
- * definition of 'using a V8 isolate' includes accessing handles or holding onto
- * object pointers obtained from V8 handles while in the particular V8 isolate.
- * It is up to the user of V8 to ensure, perhaps with locking, that this
- * constraint is not violated. In addition to any other synchronization
- * mechanism that may be used, the v8::Locker and v8::Unlocker classes must be
- * used to signal thread switches to V8.
- *
- * v8::Locker is a scoped lock object. While it's active, i.e. between its
- * construction and destruction, the current thread is allowed to use the locked
- * isolate. V8 guarantees that an isolate can be locked by at most one thread at
- * any time. In other words, the scope of a v8::Locker is a critical section.
- *
- * Sample usage:
- * \code
- * ...
- * {
- *   v8::Locker locker(isolate);
- *   v8::Isolate::Scope isolate_scope(isolate);
- *   ...
- *   // Code using V8 and isolate goes here.
- *   ...
- * } // Destructor called here
- * \endcode
- *
- * If you wish to stop using V8 in a thread A you can do this either by
- * destroying the v8::Locker object as above or by constructing a v8::Unlocker
- * object:
- *
- * \code
- * {
- *   isolate->Exit();
- *   v8::Unlocker unlocker(isolate);
- *   ...
- *   // Code not using V8 goes here while V8 can run in another thread.
- *   ...
- * } // Destructor called here.
- * isolate->Enter();
- * \endcode
- *
- * The Unlocker object is intended for use in a long-running callback from V8,
- * where you want to release the V8 lock for other threads to use.
- *
- * The v8::Locker is a recursive lock, i.e. you can lock more than once in a
- * given thread. This can be useful if you have code that can be called either
- * from code that holds the lock or from code that does not. The Unlocker is
- * not recursive so you can not have several Unlockers on the stack at once, and
- * you cannot use an Unlocker in a thread that is not inside a Locker's scope.
- *
- * An unlocker will unlock several lockers if it has to and reinstate the
- * correct depth of locking on its destruction, e.g.:
- *
- * \code
- * // V8 not locked.

-/**
- * A FunctionTemplate is used to create functions at runtime. There
- * can only be one function created from a FunctionTemplate in a
- * context.  The lifetime of the created function is equal to the
- * lifetime of the context.  So in case the embedder needs to create
- * temporary functions that can be collected using Scripts is
- * preferred.
- *
- * Any modification of a FunctionTemplate after first instantiation will trigger
- * a crash.
- *
- * A FunctionTemplate can have properties, these properties are added to the
- * function object when it is created.
- *
- * A FunctionTemplate has a corresponding instance template which is
- * used to create object instances when the function is used as a
- * constructor. Properties added to the instance template are added to
- * each object instance.
- *
- * A FunctionTemplate can have a prototype template. The prototype template
- * is used to create the prototype object of the function.
- *
- * The following example shows how to use a FunctionTemplate:
- *
- * \code
- *    v8::Local<v8::FunctionTemplate> t = v8::FunctionTemplate::New(isolate);
- *    t->Set(isolate, "func_property", v8::Number::New(isolate, 1));
- *
- *    v8::Local<v8::Template> proto_t = t->PrototypeTemplate();
- *    proto_t->Set(isolate,
- *                 "proto_method",
- *                 v8::FunctionTemplate::New(isolate, InvokeCallback));
- *    proto_t->Set(isolate, "proto_const", v8::Number::New(isolate, 2));
- *
- *    v8::Local<v8::ObjectTemplate> instance_t = t->InstanceTemplate();
- *    instance_t->SetAccessor(
-          String::NewFromUtf8Literal(isolate, "instance_accessor"),
- *        InstanceAccessorCallback);
- *    instance_t->SetHandler(
- *        NamedPropertyHandlerConfiguration(PropertyHandlerCallback));
- *    instance_t->Set(String::NewFromUtf8Literal(isolate, "instance_property"),
- *                    Number::New(isolate, 3));
- *
- *    v8::Local<v8::Function> function = t->GetFunction();
- *    v8::Local<v8::Object> instance = function->NewInstance();
- * \endcode
- *
- * Let's use "function" as the JS variable name of the function object
- * and "instance" for the instance object created above.  The function
- * and the instance will have the following properties:
- *
- * \code
- *   func_property in function == true;
- *   function.func_property == 1;
- *
- *   function.prototype.proto_method() invokes 'InvokeCallback'
- *   function.prototype.proto_const == 2;
- *
- *   instance instanceof function == true;
- *   instance.instance_accessor calls 'InstanceAccessorCallback'
- *   instance.instance_property == 3;
- * \endcode
- *
- * A FunctionTemplate can inherit from another one by calling the
- * FunctionTemplate::Inherit method.  The following graph illustrates
- * the semantics of inheritance:
- *
- * \code
- *   FunctionTemplate Parent  -> Parent() . prototype -> { }
- *     ^                                                  ^
- *     | Inherit(Parent)                                  | .__proto__
- *     |                                                  |
- *   FunctionTemplate Child   -> Child()  . prototype -> { }
- * \endcode
- *
- * A FunctionTemplate 'Child' inherits from 'Parent', the prototype
- * object of the Child() function has __proto__ pointing to the
- * Parent() function's prototype object. An instance of the Child
- * function has all properties on Parent's instance templates.
- *
- * Let Parent be the FunctionTemplate initialized in the previous
- * section and create a Child FunctionTemplate by:
- *
- * \code
- *   Local<FunctionTemplate> parent = t;
- *   Local<FunctionTemplate> child = FunctionTemplate::New();
- *   child->Inherit(parent);
- *
- *   Local<Function> child_function = child->GetFunction();
- *   Local<Object> child_instance = child_function->NewInstance();
- * \endcode
- *
- * The Child function and Child instance will have the following
- * properties:
- *
- * \code
- *   child_func.prototype.__proto__ == function.prototype;
- *   child_instance.instance_accessor calls 'InstanceAccessorCallback'
- *   child_instance.instance_property == 3;
- * \endcode
- *
- * The additional 'c_function' parameter refers to a fast API call, which
- * must not trigger GC or JavaScript execution, or call into V8 in other
- * ways. For more information how to define them, see
- * include/v8-fast-api-calls.h. Please note that this feature is still
- * experimental.

-// you plan to use these routines, you should have a good reason, such as solid

-// just for the x86; if you assume x86 semantics, x86 hardware bugs and

-// do not know what you are doing, avoid these routines, and use a Mutex.
-//
-// It is incorrect to make direct assignments to/from an atomic variable.
-// You should use one of the Load or Store routines.  The Relaxed  versions

-// Although there are currently no compiler enforcement, you are encouraged

-#define V8_BASE_EXPORT_TEMPLATE_H_
-
-// Synopsis
-//
-// This header provides macros for using FOO_EXPORT macros with explicit
-// template instantiation declarations and definitions.
-// Generally, the FOO_EXPORT macros are used at declarations,
-// and GCC requires them to be used at explicit instantiation declarations,
-// but MSVC requires __declspec(dllexport) to be used at the explicit
-// instantiation definitions instead.
-
-// Usage
-//
-// In a header file, write:
-//
-//   extern template class EXPORT_TEMPLATE_DECLARE(FOO_EXPORT) foo<bar>;
-//
-// In a source file, write:
-//
-//   template class EXPORT_TEMPLATE_DEFINE(FOO_EXPORT) foo<bar>;
-
-// Implementation notes
-//
-// The implementation of this header uses some subtle macro semantics to
-// detect what the provided FOO_EXPORT value was defined as and then
-// to dispatch to appropriate macro definitions.  Unfortunately,
-// MSVC's C preprocessor is rather non-compliant and requires special
-// care to make it work.
-//
-// Issue 1.
-//
-//   #define F(x)
-//   F()
-//
-// MSVC emits warning C4003 ("not enough actual parameters for macro
-// 'F'), even though it's a valid macro invocation.  This affects the
-// macros below that take just an "export" parameter, because export
-// may be empty.
-//
-// As a workaround, we can add a dummy parameter and arguments:
-//
-//   #define F(x,_)
-//   F(,)
-//
-// Issue 2.
-//
-//   #define F(x) G##x
-//   #define Gj() ok
-//   F(j())
-//
-// The correct replacement for "F(j())" is "ok", but MSVC replaces it
-// with "Gj()".  As a workaround, we can pass the result to an
-// identity macro to force MSVC to look for replacements again.  (This
-// is why EXPORT_TEMPLATE_STYLE_3 exists.)
-
-#define EXPORT_TEMPLATE_DECLARE(export) \
-  EXPORT_TEMPLATE_INVOKE(DECLARE, EXPORT_TEMPLATE_STYLE(export, ), export)
-#define EXPORT_TEMPLATE_DEFINE(export) \
-  EXPORT_TEMPLATE_INVOKE(DEFINE, EXPORT_TEMPLATE_STYLE(export, ), export)
-
-// INVOKE is an internal helper macro to perform parameter replacements
-// and token pasting to chain invoke another macro.  E.g.,
-//     EXPORT_TEMPLATE_INVOKE(DECLARE, DEFAULT, FOO_EXPORT)
-// will export to call
-//     EXPORT_TEMPLATE_DECLARE_DEFAULT(FOO_EXPORT, )
-// (but with FOO_EXPORT expanded too).
-#define EXPORT_TEMPLATE_INVOKE(which, style, export) \
-  EXPORT_TEMPLATE_INVOKE_2(which, style, export)
-#define EXPORT_TEMPLATE_INVOKE_2(which, style, export) \
-  EXPORT_TEMPLATE_##which##_##style(export, )
-
-// Default style is to apply the FOO_EXPORT macro at declaration sites.
-#define EXPORT_TEMPLATE_DECLARE_DEFAULT(export, _) export
-#define EXPORT_TEMPLATE_DEFINE_DEFAULT(export, _)
-
-// The "MSVC hack" style is used when FOO_EXPORT is defined
-// as __declspec(dllexport), which MSVC requires to be used at
-// definition sites instead.
-#define EXPORT_TEMPLATE_DECLARE_MSVC_HACK(export, _)
-#define EXPORT_TEMPLATE_DEFINE_MSVC_HACK(export, _) export

-// EXPORT_TEMPLATE_STYLE is an internal helper macro that identifies which
-// export style needs to be used for the provided FOO_EXPORT macro definition.
-// "", "__attribute__(...)", and "__declspec(dllimport)" are mapped
-// to "DEFAULT"; while "__declspec(dllexport)" is mapped to "MSVC_HACK".
-//
-// It's implemented with token pasting to transform the __attribute__ and
-// __declspec annotations into macro invocations.  E.g., if FOO_EXPORT is
-// defined as "__declspec(dllimport)", it undergoes the following sequence of
-// macro substitutions:
-//     EXPORT_TEMPLATE_STYLE(FOO_EXPORT, )
-//     EXPORT_TEMPLATE_STYLE_2(__declspec(dllimport), )
-//     EXPORT_TEMPLATE_STYLE_3(EXPORT_TEMPLATE_STYLE_MATCH__declspec(dllimport))
-//     EXPORT_TEMPLATE_STYLE_MATCH__declspec(dllimport)
-//     EXPORT_TEMPLATE_STYLE_MATCH_DECLSPEC_dllimport
-//     DEFAULT

-//
-// XXX: C++ reserves all identifiers containing "__" for the implementation,
-// but "__attribute__" and "__declspec" already contain "__" and the token-paste
-// operator can only add characters; not remove them.  To minimize the risk of
-// conflict with implementations, we include "foj3FJo5StF0OvIzl7oMxA" (a random
-// 128-bit string, encoded in Base64) in the macro name.

-// base::hash is an implementation of the hash function object specified by
-// C++11. It was designed to be compatible with std::hash (in C++11) and
-// boost:hash (which in turn is based on the hash function object specified by
-// the Draft Technical Report on C++ Library Extensions (TR1)).
-//
-// base::hash is implemented by calling the hash_value function. The namespace
-// isn't specified so that it can detect overloads via argument dependent
-// lookup. So if there is a free function hash_value in the same namespace as a
-// custom type, it will get called.
-//
-// If users are asked to implement a hash function for their own types with no
-// guidance, they generally write bad hash functions. Instead, we provide  a
-// simple function base::hash_combine to pass hash-relevant member variables
-// into, in order to define a decent hash function. base::hash_combine is
-// declared as:
-//
-//   template<typename T, typename... Ts>
-//   size_t hash_combine(const T& v, const Ts& ...vs);
-//
-// Consider the following example:
-//
-//   namespace v8 {
-//   namespace bar {
-//     struct Point { int x; int y; };
-//     size_t hash_value(Point const& p) {
-//       return base::hash_combine(p.x, p.y);
-//     }
-//   }
-//
-//   namespace foo {
-//     void DoSomeWork(bar::Point const& p) {
-//       base::hash<bar::Point> h;
-//       ...
-//       size_t hash_code = h(p);  // calls bar::hash_value(Point const&)
-//       ...
-//     }
-//   }
-//   }
-//
-// Based on the "Hashing User-Defined Types in C++1y" proposal from Jeffrey

-//
-// - TRAP_SEQUENCE_() must be fatal. It should not be possible to ignore the

-// - Different instances of TRAP_SEQUENCE_() must not be folded together, to
-//   ensure crash reports are debuggable. Unlike __builtin_trap(), asm volatile
-//   blocks will not be folded together.
-//   Note: TRAP_SEQUENCE_() previously required an instruction with a unique
-//   nonce since unlike clang, GCC folds together identical asm volatile
-//   blocks.
-// - TRAP_SEQUENCE_() must produce a signal that is distinct from an invalid
-//   memory access.
-// - TRAP_SEQUENCE_() must be treated as a set of noreturn instructions.
-//   __builtin_unreachable() is used to provide that hint here. clang also uses
-//   this as a heuristic to pack the instructions in the function epilogue to
-//   improve code density.
-//
-// Additional properties that are nice to have:
-// - TRAP_SEQUENCE_() should be as compact as possible.
-// - The first instruction of TRAP_SEQUENCE_() should not change, to avoid

-// The LazyInstance<Type, Traits> class manages a single instance of Type,
-// which will be lazily created on the first time it's accessed.  This class is
-// useful for places you would normally use a function-level static, but you
-// need to have guaranteed thread-safety.  The Type constructor will only ever
-// be called once, even if two threads are racing to create the object.  Get()
-// and Pointer() will always return the same, completely initialized instance.
-//
-// LazyInstance is completely thread safe, assuming that you create it safely.
-// The class was designed to be POD initialized, so it shouldn't require a
-// static constructor.  It really only makes sense to declare a LazyInstance as
-// a global variable using the LAZY_INSTANCE_INITIALIZER initializer.
-//
-// LazyInstance is similar to Singleton, except it does not have the singleton
-// property.  You can have multiple LazyInstance's of the same type, and each
-// will manage a unique instance.  It also preallocates the space for Type, as
-// to avoid allocating the Type instance on the heap.  This may help with the
-// performance of creating the instance, and reducing heap fragmentation.  This
-// requires that Type be a complete type so we can determine the size. See
-// notes for advanced users below for more explanations.
-//
-// Example usage:
-//   static LazyInstance<MyClass>::type my_instance = LAZY_INSTANCE_INITIALIZER;
-//   void SomeMethod() {
-//     my_instance.Get().SomeMethod();  // MyClass::SomeMethod()
-//
-//     MyClass* ptr = my_instance.Pointer();
-//     ptr->DoDoDo();  // MyClass::DoDoDo
-//   }
-//
-// Additionally you can override the way your instance is constructed by
-// providing your own trait:
-// Example usage:
-//   struct MyCreateTrait {
-//     static void Construct(void* allocated_ptr) {
-//       new (allocated_ptr) MyClass(/* extra parameters... */);
-//     }
-//   };
-//   static LazyInstance<MyClass, MyCreateTrait>::type my_instance =
-//      LAZY_INSTANCE_INITIALIZER;
-//
-// WARNINGS:
-// - This implementation of LazyInstance IS THREAD-SAFE by default. See
-//   SingleThreadInitOnceTrait if you don't care about thread safety.
-// - Lazy initialization comes with a cost. Make sure that you don't use it on
-//   critical path. Consider adding your initialization code to a function
-//   which is explicitly called once.
-//
-// Notes for advanced users:
-// LazyInstance can actually be used in two different ways:
-//
-// - "Static mode" which is the default mode since it is the most efficient
-//   (no extra heap allocation). In this mode, the instance is statically
-//   allocated (stored in the global data section at compile time).
-//   The macro LAZY_STATIC_INSTANCE_INITIALIZER (= LAZY_INSTANCE_INITIALIZER)
-//   must be used to initialize static lazy instances.
-//
-// - "Dynamic mode". In this mode, the instance is dynamically allocated and
-//   constructed (using new) by default. This mode is useful if you have to
-//   deal with some code already allocating the instance for you (e.g.
-//   OS::Mutex() which returns a new private OS-dependent subclass of Mutex).
-//   The macro LAZY_DYNAMIC_INSTANCE_INITIALIZER must be used to initialize
-//   dynamic lazy instances.

-// very low-level functions like the protobuf library and fast math
-// support.
-//
-//   float f = 3.14159265358979;
-//   int i = bit_cast<int32>(f);
-//   // i = 0x40490fdb
-//
-// The classical address-casting method is:
-//
-//   // WRONG
-//   float f = 3.14159265358979;            // WRONG
-//   int i = * reinterpret_cast<int*>(&f);  // WRONG
-//
-// The address-casting method actually produces undefined behavior
-// according to ISO C++ specification section 3.10 -15 -.  Roughly, this
-// section says: if an object in memory has one type, and a program
-// accesses it with a different type, then the result is undefined
-// behavior for most values of "different type".
-//
-// This is true for any cast syntax, either *(int*)&f or
-// *reinterpret_cast<int*>(&f).  And it is particularly true for
-// conversions between integral lvalues and floating-point lvalues.
-//
-// The purpose of 3.10 -15- is to allow optimizing compilers to assume
-// that expressions with different types refer to different memory.  gcc
-// 4.0.1 has an optimizer that takes advantage of this.  So a
-// non-conforming program quietly produces wildly incorrect output.
-//
-// The problem is not the use of reinterpret_cast.  The problem is type
-// punning: holding an object in memory of one type and reading its bits
-// back using a different type.
-//
-// The C++ standard is more subtle and complex than this, but that
-// is the basic idea.
-//
-// Anyways ...
-//
-// bit_cast<> calls memcpy() which is blessed by the standard,
-// especially by the example in section 3.9 .  Also, of course,
-// bit_cast<> wraps up the nasty logic in one place.
-//
-// Fortunately memcpy() is very fast.  In optimized mode, with a
-// constant size, gcc 2.95.3, gcc 4.0.1, and msvc 7.1 produce inline
-// code with the minimal amount of data movement.  On a 32-bit system,
-// memcpy(d,s,4) compiles to one load and one store, and memcpy(d,s,8)
-// compiles to two loads and two stores.
-//
-// I tested this code with gcc 2.95.3, gcc 4.0.1, icc 8.1, and msvc 7.1.
-//
-// WARNING: if Dest or Source is a non-POD type, the result of the memcpy
-// is likely to surprise you.

-//
-// This header is intended to be included only by v8's internal code. Users
-// should not use this directly.
-//
-// This is basically a portable version of pthread_once().
-//
-// This header declares:
-// * A type called OnceType.
-// * A macro V8_DECLARE_ONCE() which declares a (global) variable of type
-//   OnceType.
-// * A function CallOnce(OnceType* once, void (*init_func)()).
-//   This function, when invoked multiple times given the same OnceType object,
-//   will invoke init_func on the first call only, and will make sure none of
-//   the calls return before that first call to init_func has finished.
-//
-// Additionally, the following features are supported:
-// * A macro V8_ONCE_INIT which is expanded into the expression used to
-//   initialize a OnceType. This is only useful when clients embed a OnceType
-//   into a structure of their own and want to initialize it statically.
-// * The user can provide a parameter which CallOnce() forwards to the
-//   user-provided function when it is called. Usage example:
-//     CallOnce(&my_once, &MyFunctionExpectingIntArgument, 10);
-// * This implementation guarantees that OnceType is a POD (i.e. no static
-//   initializer generated).
-//
-// This implements a way to perform lazy initialization.  It's more efficient
-// than using mutexes as no lock is needed if initialization has already
-// happened.
-//
-// Example usage:
-//   void Init();
-//   V8_DECLARE_ONCE(once_init);
-//
-//   // Calls Init() exactly once.
-//   void InitOnce() {
-//     CallOnce(&once_init, &Init);
-//   }
-//
-// Note that if CallOnce() is called before main() has begun, it must
-// only be called by the thread that will eventually call main() -- that is,
-// the thread that performs dynamic initialization.  In general this is a safe
-// assumption since people don't usually construct threads before main() starts,
-// but it is technically not guaranteed.  Unfortunately, Win32 provides no way
-// whatsoever to statically-initialize its synchronization primitives, so our
-// only choice is to assume that dynamic initialization is single-threaded.

-// These are the differences between the specification and the implementation:
-// - Constructors do not use 'constexpr' as it is a C++14 extension.

-// Note that T cannot have a constructor T(Optional<T>) etc. Optional<T> checks
-// T's constructor (specifically via IsConvertibleFromOptional), and in the
-// check whether T can be constructible from Optional<T>, which is recursive
-// so it does not work. As of Feb 2018, std::optional C++17 implementation in

-// The following helper template addresses a corner case in range checks for
-// conversion from a floating-point type to an integral type of smaller range
-// but larger precision (e.g. float -> unsigned). The problem is as follows:
-//   1. Integral maximum is always one less than a power of two, so it must be
-//      truncated to fit the mantissa of the floating point. The direction of
-//      rounding is implementation defined, but by default it's always IEEE
-//      floats, which round to nearest and thus result in a value of larger
-//      magnitude than the integral value.
-//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
-//                                   // is 4294967295u.
-//   2. If the floating point value is equal to the promoted integral maximum
-//      value, a range check will erroneously pass.
-//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
-//                                            // loss in rounding up to float.
-//   3. When the floating point value is then converted to an integral, the
-//      resulting value is out of range for the target integral type and
-//      thus is implementation defined.
-//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
-// To fix this bug we manually truncate the maximum value when the destination
-// type is an integral of larger precision than the source floating-point type,
-// such that the resulting maximum is represented exactly as a floating point.

-  Liveedit step-by-step:
-  1. calculate diff between old source and new source,

-  4. mark literals with changed code as changed, all others as unchanged,
-  5. check that for changed literals there are no:
-    - running generators in the heap,
-    - non droppable frames (e.g. running generator) above them on stack.
-  6. mark the bottom most frame with changed function as scheduled for restart
-     if any,
-  7. for unchanged functions:
-    - deoptimize,
-    - remove from cache,
-    - update source positions,
-    - move to new script,
-    - reset feedback information and preparsed scope information if any,
-    - replace any sfi in constant pool with changed one if any.
-  8. for changed functions:
-    - deoptimize
-    - remove from cache,
-    - reset feedback information,
-    - update all links from js functions to old shared with new one.
-  9. swap scripts.

+ * `sortedTimers_` must always be sorted by dueTime (stable for equal
+ * dueTimes) and in sync with `timerMap_` (except tombstones, which only live
+ * in `sortedTimers_`).
+ *
+ * Scheduling model: every scheduled timer posts one anonymous "due token"
+ * through the runtime EventLoop's ordered lane, at a due time >= the timer's.
+ * Timers therefore share one due-ordered domain with ordered macrotasks and
+ * stay in fire-date order with foreign runloop timers. The token does not
+ * name a timer: the EventLoop drain consumes the earliest due item across
+ * this list and its own ordered entries. Cancelling recalls the pending
+ * token when possible and otherwise leaves a tombstone so the matured token
+ * consumes a slot as a no-op instead of lending its position to a later item.

+/**
+ BasicLockable wrapper over os_unfair_lock — the fastest blocking lock on
+ Darwin. Drive it with std::lock_guard<UnfairMutex>.
+
+ Prefer this over SpinLock for any critical section that can block (syscalls,
+ objc runtime calls, allocation) or that can see bursty contention: waiters
+ sleep in the kernel and donate their priority to the holder, while SpinLock
+ busy-waits in userspace, invisible to the scheduler. Benchmarked on an
+ M-series host: under an 8-thread burst on a short section os_unfair_lock is
+ ~30x faster than SpinLock at ~33x less CPU, and against a holder that sleeps
+ mid-section waiters cost ~100x less CPU. SpinLock stays marginally faster
+ (~0.2 ns/op) only for uncontended nanosecond-scale sections — its documented
+ niche (selector caching).
+
+ NATIVESCRIPT_UNFAIR_LOCK_ADAPTIVE_SPIN opts lock() into
+ os_unfair_lock_lock_with_options() with kernel-informed adaptive spinning —
+ the approach Firefox adopted for its nanosecond-hot allocator locks:
+ https://hacks.mozilla.org/2022/10/improving-firefox-responsiveness-on-macos/
+
+ Experiments only, never ship it:
+ - PRIVATE API (os/lock_private.h); App Review flags the symbol.
+ - It only wins for nanosecond-scale sections at low contention with the
+   holder on-core (measured ~2x over plain os_unfair_lock at 2 threads).
+   Under bursty contention it degenerates to spinlock behavior (~30x slower,
+   ~30x more CPU at 8 threads), it is the worst option under QoS inversion,
+   and it changes nothing when the holder sleeps.

+# Runtime builtins
+
+The `.js` files in this directory are the runtime's internal JavaScript. At
+build time the "Generate RuntimeBuiltins" Xcode phase runs `tools/js2c.mjs`,
+which embeds them into `NativeScript/runtime/generated/RuntimeBuiltins.cpp`;
+at runtime `BuiltinLoader::RunBuiltin` compiles and executes them with an
+`internal/<name>.js` script origin and a process-wide bytecode cache.
+
+## Contract (Node's module wrapper + internalBinding idiom)
+
+Every file is compiled as a **function body** via `v8::ScriptCompiler::CompileFunction`
+with the fixed parameters `exports`, `require`, `module`, `binding` and
+`primordials`:
+
+```js
+const { someNative, anotherNative } = binding;
+const { ArrayPrototypeSlice, ObjectCreate } = primordials;
+const { inspect } = require("ns:util");
+
+module.exports = somethingTheCallSiteNeeds;
+```
+
+- `binding` is a plain object of natives built by the C++ call site; a file
+  that needs nothing from C++ simply doesn't mention it.
+- `require` resolves **builtin specifiers only** (`ns:util`, `node:util`, …),
+  never a path or a package; an unknown one throws
+  `No such built-in module: <specifier>`. It is how a `node:` shim consumes the
+  `ns:` module it adapts, and it materializes that module on first use.
+  Requiring a module that is still loading throws rather than recursing.
+- `primordials` is the frozen intrinsics snapshot built by `primordials.js`
+  (see below), the same object for every builtin in an isolate.
+- **`module.exports` is the export channel** — whatever it holds when the file
+  finishes is what `RunBuiltin` hands back to C++ (used for factory functions
+  and init results). Both CommonJS styles work: replace the whole export with
+  `module.exports = x`, or hang properties off `exports`. A file that only
+  installs globals exports nothing and the call site ignores the value.
+- **No top-level `return`.** It would work — these are function bodies — but
+  every tool that isn't reading this repo's ESLint config (editors' TS server,
+  prettier, review bots) rejects the file as invalid JavaScript.
+- Strict mode is per-file: start the file with `"use strict";` to opt in.
+- `inspect.js` is the console formatter (util.inspect-lite, exposed as the
+  internal `__inspect` global): budgeted output, no getter invocation,
+  tamper-immune via primordials. Console routes all object formatting
+  through it.
+- `ns-util.js` is the `ns:util` module app code requires and `node-util.js` the
+  `node:util` shim: one source file per specifier, the shim owning every bit of
+  Node compatibility. See `docs/ns-builtin-modules.md` for the cross-runtime
+  contract.
+- Destructure `binding` and `primordials` once, at the top of the file, so the
+  file's dependencies are visible and greppable.
+
+## Rules
+
+- Run at isolate init, before any user code: capture any global you rely on
+  (e.g. `globalThis.Event`) eagerly so later monkey-patching can't break you.
+  For intrinsics that is what `primordials` is; for everything else
+  (`URLSearchParams`, …) capture it into a file-level `const`.
+- No `import`/`export` — these are classic function bodies, not modules.
+- ESLint (`eslint.config.mjs` at the repo root, run by lint-staged) declares
+  `exports`, `require`, `module`, `binding`, `primordials` and the reachable
+  native globals; `no-undef` is the typo net. If a builtin starts using a new native
+  global, add it there. `no-restricted-properties` fails the lint on direct use
+  of the captured statics (`JSON.stringify`, `Object.defineProperty`, …).
+  Uncurried instance methods can't be matched that way, so `list.slice()`
+  instead of `ArrayPrototypeSlice(list)` is caught by review, not by the
+  linter.
+- File names are kebab-case; the name determines the `BuiltinId` enum value
+  (`promise-proxy.js` → `kPromiseProxy`) and the script origin. New files must
+  also be added to `tools/js2c-inputs.xcfilelist` — the build fails with an
+  explicit message if that list drifts out of sync (`js2c.mjs --filelist`).
+
+## primordials
+
+`primordials.js` runs first in every isolate — lazily, on the first
+`RunBuiltin` call, which happens during runtime init — and its frozen,
+null-prototype export is cached per isolate (`Caches::Primordials`) and
+handed to every other builtin, so a builtin that compiles later in the
+isolate's life still sees intrinsics as they were before user code ran.
+
+Naming follows Node: statics keep their path (`JSONStringify`,
+`ObjectDefineProperty`), instance methods are **uncurried** so the receiver
+becomes the first argument:
+
+```js
+ArrayPrototypeSlice(list, 1)     // not list.slice(1)
+FunctionPrototypeCall(cb, this, event)  // not cb.call(this, event)
+```
+
+Uncurrying is `Function.prototype.bind.bind(Function.prototype.call)`, which on
+the jitless configuration the runtime ships is both faster than a captured
+`fn.call(...)` and immune to a replaced `Function.prototype.call`.
+
+Add only what a builtin actually needs; this is not a mirror of Node's list.
+Plain constructor calls made once at init time (`new Map()` while
+bootstrapping) may stay direct — the rule targets code in closures that
+outlive init.

+@ref basic_json::is_string(), @ref basic_json::is_boolean(),

+@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
+@ref basic_json::is_structured() rely on it.
+
+@note There are three enumeration entries (number_integer, number_unsigned, and
+number_float), because the library distinguishes these three types for numbers:
+@ref basic_json::number_unsigned_t is used for unsigned integers,
+@ref basic_json::number_integer_t is used for signed integers, and
+@ref basic_json::number_float_t is used for floating-point numbers or to
+approximate integers which do not fit in the limits of their respective type.

+    This function scans a string according to Sect. 6 of RFC 8259.
+
+    The function is realized with a deterministic finite state machine derived
+    from the grammar described in RFC 8259. Starting in state "init", the
+    input is read and used to determined the next state. Only state "done"
+    accepts the number. State "error" is a trap state to model errors. In the
+    table below, "anything" means any character but the ones listed before.

+    state    | 0        | 1-9      | e E      | +       | -       | .        | anything

+
+    The state machine is realized with one label per state (prefixed with
+    "scan_number_") and `goto` statements between them. The state machine
+    contains cycles, but any cycle can be left when EOF is read. Therefore,
+    the function is guaranteed to terminate.
+
+    During scanning, the read bytes are stored in token_buffer. This string is
+    then converted to a signed integer, an unsigned integer, or a
+    floating-point number.
+
+    @return token_type::value_unsigned, token_type::value_integer, or
+            token_type::value_float if number could be successfully scanned,

+
+    @note The scanner is independent of the current locale. Internally, the
+          locale's decimal point is used instead of `.` to work with the

 # Updating/Building V8 engine source
 
-In order to build the V8 engine for iOS and produce the static libraries used in the NativeScript iOS runtime follow these steps:
-
-**Prerequisites:**
-
-```
-git clone https://github.com/NativeScript/ios.git
-cd ios
-```
-
-You will need Google [depot_tools](https://www.chromium.org/developers/how-tos/install-depot-tools)
-
-* If you have not cloned the repo yet, clone the following and export a path setting so they can be referenced properly:
-
-```
-git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
-
-// copy/paste this command in current terminal window:
-export PATH=`pwd`/depot_tools:"$PATH"
-```
-
-1. Fetch the latest v8 source (or specific version):
-
-> If you have an existing v8 source fetched, delete the folder, and fetch it fresh each time updates are needed.
-
-```
-// IMPORTANT: Make sure you are inside the clone of this repo...
-cd ios
-
-// Fetch v8 source:
-fetch v8
-```
-
-This will create a `v8` repo folder automatically checking out the `master` branch.
-
-Always check https://omahaproxy.appspot.com/ for the specific version you intend to build.
-
-2. Ensure you checkout the version you intend to build:
-
-```
-cd v8
-
-// for example:
-git checkout 9.2.230.18
-
-gclient sync
-```
-
-This will checkout a specific tag and fetch additional dependencies for building the intended version.
-
-3. Apply patches from v8 updates to the iOS runtime:
-
-```
-npm run apply-patches
-```
-
-NOTE: Oftentimes the patches may not apply immediately and can run into issues like this:
+The V8 libraries and the headers that must match them are not committed here.
+`./download_v8.sh` installs them from the release pinned in `V8_RELEASE`,
+verifying the archives against the checksums published with them. It is a no-op
+once they are in place, and `build_nativescript.sh` calls it for you.
 
 ```
-error: patch failed: BUILD.gn:538
-error: BUILD.gn: patch does not apply
-error: patch failed: src/inspector/inspector_protocol_config.json:21

+./download_v8.sh --release <tag>       # install a different one
+V8_SKIP_DOWNLOAD=1 ./build_all_ios.sh  # keep a local V8 build instead
 ```
 
-You can look at each patch failure, for example `BUILD.gn: patch does not apply`, you can apply the patch manually instead. This can be done by opening the `./v8.patch` file and applying each patch manually to the corresponding file.
+To change the V8 version, or to build it yourself, see
+[NativeScript/v8-buildscripts](https://github.com/NativeScript/v8-buildscripts).
+It builds every Android ABI and Apple variant in CI and publishes them as
+release assets — which it has to, because the full matrix cannot be produced on
+any single machine: the 32-bit Android ABIs need an ia32-capable host and the
+Apple variants need macOS.
 
-4. Build v8 source:
 
-```
-npm run build-v8-source
-```
-
-*Troubleshooting build errors*
-
-* Example failure 1:
+# Building a Distribution Package
 
-```
-@Mac ios % npm run build-v8-source
+1. (Optional) Bump the version in package.json
 
-> @nativescript/ios@8.1.0 build-v8-source
-> ./build_v8_source.sh
+2. Run: `npm run update-version` (*This will update the runtime headers with version info*)
 
-~/Documents/ios/v8 ~/Documents/ios
-Building for out.gn/x64-release (simulator)
-Done. Made 212 targets from 92 files in 4004ms
-ninja: Entering directory `out.gn/x64-release'
-ninja: error: unknown target 'v8_libsampler'
-```
+3. Build & pack: `npm run build-ios`
 
-In this case, the v8_libsampler module no longer needs to be built specifically as a target, therefore the MODULES inside the `build_v8_source.sh` can be modified to remove the target of `v8_libsampler` and the build can be invoked again.
+This will create `dist/nativescript-ios-{version}.tgz`.
 
-* Example failure 2:
+The runtime's NativeScript / TKLiveSync xcframeworks are consumed via SwiftPM, and the
+package can be built in two modes (`--spm-mode`, see `./build_npm_ios.sh --help`):
 
-```
-ERROR at //build/config/ios/ios_sdk.gni:181:33: Script returned non-zero exit code.
-    ios_code_signing_identity = exec_script("find_signing_identity.py",
-
-Automatic code signing identity selection was enabled but could not
-find exactly one codesigning identity matching "Apple Development".
-
-Check that the keychain is accessible and that there is exactly one
-valid codesigning identity matching the pattern. Here is the parsed
-output of `xcrun security find-identity -v -p codesigning`:
-
-  1) 1ABE0***********************************: "Apple Development: Your Name (U4********)"
-  2) CB529***********************************: "Apple Distribution: Your Org (29********)"
-  3) BACD5***********************************: "Apple Development: Your Name (VV********)"
-  4) 0D42D***********************************: "Apple Development: Your Team (D3********)"
-  5) 055BA***********************************: "Apple Development: Your Name (GF********)"
-  6) A5306***********************************: "Apple Development: Your Name (9V***********)"
-    6 valid identities found
-```
+- **`embedded` (default)** — a self-contained package: the freshly built xcframeworks are
+  embedded (as zips, since npm strips symlinks) at `framework/internal/local-spm` together
+  with a local SwiftPM manifest, and the app template consumes them by relative path.
+  The tgz works on any machine. This is what local builds and PR artifacts produce.
+- **`remote`** — the deploy shape published to npm by the release workflow
+  (`npm run build-ios -- --spm-mode=remote`): no binaries are embedded; the app template
+  pins https://github.com/NativeScript/ios-spm at exactly the package version. The release
+  workflow uploads the xcframework zips as GitHub Release assets and tags ios-spm to match,
+  so a remote-mode package only resolves for versions that shipped through
+  `.github/workflows/npm_release.yml` — don't use this mode for local builds.
 
-If this occurs you can manually modify `v8/build/config/ios/ios_sdk.gni`. A property named `ios_code_signing_identity`. You can set that explicitly to one of your code signing identities. You can use the command it suggests to list out your identities in full: `xcrun security find-identity -v -p codesigning` - Copy the id and paste it as the value of `ios_code_signing_identity`.
+# Local Development & Linking
 
-You will want to make `ios_code_signing_identity_description` an empty string so the final change should look something like this:
+To use a locally built runtime in an app, build the default (embedded) package and point
+the {N} CLI at it:
 
+```bash
+npm run build-ios
+ns platform add ios --framework-path=/path/to/ns-v8ios-runtime/dist/nativescript-ios-{version}.tgz
 ```
-# Explicitly select the identity to use for codesigning. If defined, must
-# be set to a non-empty string that will be passed to codesigning. Can be
-# left unspecified if ios_code_signing_identity_description is used instead.
-ios_code_signing_identity = "...your-id..."
-
-# Pattern used to select the identity to use for codesigning. If defined,
-# must be a substring of the description of exactly one of the identities by
-# `security find-identity -v -p codesigning`.
-ios_code_signing_identity_description = ""
-```
-
-5. If building of the v8 source succeeds, Verify the build output.
-
-The compiled fat static libraries will be placed inside the `v8/dist` folder.
-
-# Building a Distribution Package
-
-1. Bump the version in package.json
-
-2. Run: `npm run update-version` (*This will update the runtime headers with version info*)
 
-3. Build & pack: `npm run build`
+Because the embedded package is self-contained, the tgz can be copied to other machines,
+shared with teammates, or consumed by an app's CI. The same applies to the `npm-package`
+artifact produced by this repo's pull-request workflow — download it and use it with
+`--framework-path` directly.
 
-This will create: `dist/npm/nativescript-ios-{version}.tgz` NPM package ready for publishing.
+To rebuild just the package after runtime changes (without the full `build-ios` pipeline),
+re-run `./build_spm_artifacts.sh ios` followed by `./build_npm_ios.sh`.

+    //    from native — rethrow the NSException at that boundary after scope

+    //    surface a NativeScriptFatalJSException instead of a nil default.)
+    //
+    //    IMPORTANT LIMITATION (verified empirically): the native→JS block /
+    //    overridden-method boundary (ArgConverter::MethodCallback, e.g.
+    //    invokeBlockCatchingException) does NOT get a synchronous rethrow. It uses
+    //    tc.ReThrow(), so an unbranded plain Error is surfaced to V8 as a pending
+    //    exception and is caught in JS up-stack (or reported later at an uncaught
+    //    Invoke), never during the block's own frame. A native @try/@catch around
+    //    invokeBlockCatchingException therefore does NOT catch a plain Error under
+    //    "throw" — it still surfaces to JS. Use interop.escapeException(err) to
+    //    force a synchronous native @throw at that boundary regardless of policy.
+    //
+    // 2. LOOP-ORIGINATED (deferred clean-frame throw): an uncaught error in a
+    //    setTimeout callback has no originating boundary to claim it, so it is
+    //    thrown from a clean, scope-free frame on the runtime loop and terminates
+    //    the app (nothing catches it) with a NativeScriptFatalJSException crash
+    //    report:
+    //
+    //      setTimeout(() => { throw new Error("policy-throw-timer"); }, 0);
+    //
+    // Default-off behavior (report + continue) is covered by every other suite

-## TNS Shared Tests
-
-Currently targeting the Telerik NativeScript runtimes for:
- - iOS
- - android
- 
-The tests should cover sommon functionality such as the "require" implementations,
-basic inheritance scenarios, ECMA version etc.
-
-[The unit tests are written in Jasmine.](http://jasmine.github.io/2.0/introduction.html)
-
-To run the tests you should add this repo as submodule in the app/shared folder.
-There is a satelite repo that contains module which should be added as submodule in tns_modules/shared respectively.
-
-## Fixtures
-`TNSLog(text)` method is expected to be defined in the global object collecting messages.
-`TNSGetOutput()` method returns all messages collected in TNSLog.
-`TNSClearOutput()` clears the collected messages in TNSLog.
-`__approot` global variable should point the path to the root folder of the app, the one where 'app' and 'tns_modules' are located. The path should start with leading slash.
-

+# Error handling
+
+The runtime implements the WHATWG error model at the global level: uncaught JavaScript exceptions and unhandled promise rejections are dispatched as cancelable events on `globalThis`, native `NSException`s round-trip into JavaScript with the original object attached, and `interop.escapeException` forwards a JavaScript throw to a native caller as a real `@throw`. By default nothing crashes the app — reporting is opt-out per error (`preventDefault()`), and rethrowing unprevented errors natively is opt-in (`uncaughtErrorPolicy: "throw"`).
+
+## Quick reference
+
+| Situation | Default behavior |
+|---|---|
+| Uncaught JS exception | Cancelable `error` event on `globalThis` → if unprevented: `__onUncaughtError` hook, fatal log, error modal in debug. App keeps running. |
+| Unhandled promise rejection | Tracked per isolate, reported once per run-loop turn: cancelable `unhandledrejection` event → same fallback chain, prefixed `Unhandled promise rejection:`. |
+| `.catch()` added after the report | `rejectionhandled` event (non-cancelable), carrying the original reason. |
+| JS throw inside a native callback (overridden method, block, property accessor, adapter) | Reported through the same pipeline; the native caller receives a zero/`nil` default and continues. The process never aborts on a JS throw. |
+| `throw interop.escapeException(x)` inside a native callback | Converted to a real native `@throw` at the boundary — no JS-side reporting; the native caller's `@try/@catch` sees the exception. |
+| Native `@throw` during a JS→native call | Surfaced to JS as an `Error` carrying the original exception as `error.nativeException`. |
+
+## JavaScript API
+
+### Global error events
+
+```js
+globalThis.addEventListener("error", (e) => {
+  // e is an ErrorEvent: { message, error, filename, lineno, colno }
+  // (filename/lineno/colno are not populated yet)
+  console.log(e.message, e.error);
+  e.preventDefault(); // marks the error handled: no hook, no fatal log, no modal
+});
+
+globalThis.addEventListener("unhandledrejection", (e) => {
+  // e is a PromiseRejectionEvent: { promise, reason }
+  console.log(e.reason);
+  e.preventDefault();
+});
+
+globalThis.addEventListener("rejectionhandled", (e) => {
+  // fired (as a task, on the next run-loop turn) when a handler is attached
+  // to a promise whose rejection was already reported; carries the original
+  // reason. Not cancelable.
+});
+```
+
+Notes:
+
+- `error` and `unhandledrejection` are `cancelable`; `preventDefault()` suppresses every downstream consequence (legacy hooks, fatal log, error modal, the `uncaughtErrorPolicy: "throw"` rethrow).
+- Events fire even if app code overwrites `globalThis.dispatchEvent` — native dispatch goes through closures captured at startup.
+- A listener that throws does not stop the remaining listeners; the thrown value is routed to the fatal reporting tail directly (never recursively dispatched as another `error` event).
+- The events also fire on worker globals. A worker's unhandled rejection dispatches `unhandledrejection` on the worker's own global first; only when unprevented does it continue to the worker-global `onerror` and then to the main isolate's `worker.onerror`, mirroring uncaught worker errors.
+
+### `reportError`
+
+Routes a caught-but-fatal error through the exact same pipeline as an uncaught exception:
+
+```js
+reportError(new Error("something unrecoverable"));
+```
+
+### Event classes
+
+`Event`, `EventTarget`, `ErrorEvent` and `PromiseRejectionEvent` are installed as global constructors. `Event`/`EventTarget` are general-purpose (registration order, `once`/`capture` options, `stopImmediatePropagation`, `handleEvent` objects) and usable for your own eventing:
+
+```js
+const target = new EventTarget();
+target.addEventListener("tick", (e) => { ... }, { once: true });
+target.dispatchEvent(new Event("tick")); // returns !defaultPrevented
+```
+
+### What lands on the events
+
+The stacks live on the error/reason **value**, not on the event — and the thrown value can be anything, so shape-check before use. Object-valued errors/reasons additionally carry a combined `stackTrace` string property, populated **before** the event dispatches (`e.error.stackTrace` / `e.reason.stackTrace` — same contract on Android):
+
+| You wrote | `e.error` / `e.reason` is | JS stack | Native exception |
+|---|---|---|---|
+| `throw new Error("x")` | that `Error` | `e.error.stack` | — |
+| called a native method that threw, without try/catch | an `Error` with `name` = the `NSException` name, `message` = its reason | `e.error.stack` (the JS call site) | `e.error.nativeException` — the original `NSException` (`.name`, `.reason`, `.userInfo`, `.callStackSymbols` captured at the native throw) |
+| `throw NSException.exceptionWithNameReasonUserInfo(...)` | the wrapped `NSException` itself — not an `Error`, no `.stack` | — | `e.error` directly (`instanceof NSException`); `.callStackSymbols` is only populated if it was actually thrown natively, not when merely constructed |
+
+### Catching native exceptions
+
+```js
+try {
+  NSArray.alloc().init().objectAtIndex(3);
+} catch (e) {
+  e.nativeException instanceof NSException; // true
+  e.nativeException.name;                   // "NSRangeException"
+  e.nativeException.reason;                 // "... index 3 beyond bounds ..."
+  e.nativeException.callStackSymbols;       // native frames at the throw site
+}
+```
+
+Methods with `NSError**` out-parameters are unchanged: they throw a JS `Error` with `code`, `domain` and `nativeException` set to the `NSError`.
+
+### Forwarding a throw to native: `interop.escapeException`
+
+A plain JS throw inside a native callback is reported and the native caller continues with a default value. When the native caller *must* observe the failure — a parent `@try/@catch` is waiting, or you want a real native crash — brand the throw:
+
+```js
+const Delegate = NSObject.extend({
+  someNativeMethod() {
+    throw interop.escapeException(new Error("propagate me natively"));
+  },
+}, { protocols: [SomeProtocol] });
+```
+
+At the JS→native boundary the branded throw becomes a native `@throw` (executed only after every V8 scope has unwound). Semantics:
+
+- `escapeException(err)` returns a JS `Error` (message/stack copied), so it behaves like a normal throw in pure-JS paths; the brand is an isolate-private symbol that user code cannot forge. Passing an already-branded value is a no-op; calling with no argument throws `TypeError`.
+- If `err` is (or carries via `.nativeException`) a native `NSException`, the **original object** is rethrown — a parent `@catch (NSRangeException *)` matches, and identity is preserved:
+
+```js
+try {
+  riskyNativeCall();
+} catch (e) {
+  throw interop.escapeException(e); // rethrows the exact original NSException
+}
+```
+
+- Otherwise an `NSException` is synthesized: `name` from the error's name, `reason` from its message plus the JS stack, and the stacks in `userInfo` (see the native section).
+- An escaped exception that nothing catches natively terminates the app with a real native crash report.
+- **An explicit escape always wins.** A branded error that reaches the uncaught machinery *anywhere* — thrown uncaught in a timer/microtask, used as an unhandled rejection reason, or thrown from inside an `error`/`unhandledrejection` listener — converts straight to the native throw: no events are dispatched, no hooks run, and `preventDefault()` cannot veto it (matching Android, where the brand is checked before any dispatch).
+- `escapeException` is the per-call tool and works **regardless of `uncaughtErrorPolicy`** and **at every boundary** (including native→JS blocks and overridden methods): it bypasses JS-side reporting entirely and converts *that one throw* into a native `@throw`. `uncaughtErrorPolicy: "throw"` is the global policy — it applies only to *unprevented, unbranded* errors, only *after* they are reported, and only rethrows synchronously at boundaries that report within their own frame (property accessors / adapters); block and overridden-method boundaries fall back to the deferred clean-frame throw. When you need a native handler around a specific block/method call to catch a JS failure, use `escapeException`, not the policy.
+
+Limitations: two boundaries execute under the *caller's* live V8 scopes and therefore cannot convert a branded escape into a native throw — fast enumeration (`for...in` over a JS object from native) and `DictionaryAdapter.getProperties`. There, a branded escape surfaces as an ordinary JS exception.
+
+## Native API
+
+### Catching escaped exceptions
+
+```objc
+@try {
+  [jsImplementedObject someNativeMethod];
+} @catch (NSException *e) {
+  // For synthesized escapes: e.name/e.reason come from the JS error, and
+  // e.reason includes the JS stack. For rethrown originals: e is the very
+  // same object that was originally thrown natively.
+}
+```
+
+### JS stack traces on `NSException`
+
+Every `NSException` produced by the escape/crash machinery carries the JavaScript context:
+
+```objc
+#import <NativeScript/NSExceptionSupport.h>
+
+NSString *jsStack = exception.tns_javascriptStackTrace; // nil when no JS involvement
+```
+
+The accessor is uniform across all cases; underneath:
+
+| Exception | Where the JS stack lives |
+|---|---|
+| Synthesized escape | `userInfo[TNSJavaScriptStackTraceKey]` (`@"JavaScriptStack"`), plus `userInfo[TNSJavaScriptEscapeStackTraceKey]` (`@"JavaScriptEscapeStack"`) when the `escapeException` call site differs from the error's origin; also appended to `reason` |
+| Rethrown original `NSException` | attached as an associated object (identity and `userInfo` are untouched); the string combines the origin stack and the escape site |
+| `uncaughtErrorPolicy: "throw"` fatal (`NativeScriptFatalJSException`) | `userInfo[TNSJavaScriptStackTraceKey]`, also in `reason` |
+
+`tns_javascriptStackTrace` and the two `userInfo` keys are the stable contract for crash-SDK integrations.
+
+## Configuration
+
+`uncaughtErrorPolicy` in the app's `package.json` is the uncaught-error contract, unified across NativeScript runtimes (9.1+):
+
+```jsonc
+{ "uncaughtErrorPolicy": "report" } // default: report and keep running
+{ "uncaughtErrorPolicy": "throw" }  // unprevented errors are rethrown natively
+```
+
+- `"report"` — after the event dispatch and legacy hooks, log the fatal message and keep the app alive.
+- `"throw"` — additionally rethrow the error as a real `NSException` (`NativeScriptFatalJSException`, JS stack in `reason` and `userInfo`). When a JS→native boundary reports the error **synchronously within its own frame** (a property accessor or `DictionaryAdapter` read invoked from native), it is rethrown **synchronously at that boundary** — after every V8 scope unwinds — so a native `@try/@catch` around that call can catch it, matching Android. Otherwise — loop-originated errors (timers, microtasks, unhandled rejections) and native→JS **block / overridden-method** callbacks (whose throw is surfaced to V8 and reported up-stack, not in the callback's own frame) — it is thrown from a clean frame on the runtime loop on the next turn. Either way this is a **throw, not a crash guarantee**: the app terminates only if nothing catches it — which also means crash reporters capture it properly when it does. To force a synchronous native `@throw` at *any* boundary regardless of policy, use `interop.escapeException`.
+- Unknown values log a warning once and fall back to `"report"`.
+
+Deprecated: `discardUncaughtJsExceptions` is still honored in full for now — unprevented errors route to `__onDiscardedError` instead of `__onUncaughtError`, the fatal log is skipped, and any `"throw"` policy is suppressed — but it logs a deprecation warning. Migrate to an `error`/`unhandledrejection` listener calling `preventDefault()` (per-error, more precise) and `uncaughtErrorPolicy`.
+
+Terminal-path decision table for an uncaught error / unhandled rejection:
+
+| Condition | legacy hook called | fatal log / modal | native throw |
+|---|---|---|---|
+| `"report"` (default) | `__onUncaughtError` | yes | no |
+| `"throw"`, unprevented | `__onUncaughtError` | yes | yes |
+| listener called `preventDefault()` | no | no | no |
+| `discardUncaughtJsExceptions` (deprecated) | `__onDiscardedError` | no | no |
+
+## Crash reporter integration
+
+JS side — attach both the JS and native exception from one listener:
+
+```js
+function nativeExceptionOf(value) {
+  if (value instanceof NSException) return value;
+  return (value && value.nativeException instanceof NSException) ? value.nativeException : null;
+}
+
+globalThis.addEventListener("error", (e) => {
+  const err = e.error;
+  const native = nativeExceptionOf(err);
+  crashReporter.capture(err instanceof Error ? err : new Error(e.message), {
+    nativeName: native?.name,
+    nativeReason: native?.reason,
+    nativeStack: native?.callStackSymbols, // NSArray of symbolicated frames
+  });
+  // e.preventDefault(); // only if the reporter fully owns error handling
+});
+```
+
+Native side — for the `NSUncaughtExceptionHandler`/signal layer, read `exception.tns_javascriptStackTrace` (or the `userInfo` keys) to attach the JS stack to crashes that never pass through the JS event layer (escaped exceptions, `uncaughtErrorPolicy: "throw"`).
+
+## Legacy hooks (deprecated)
+
+`global.__onUncaughtError` and `global.__onDiscardedError` keep working exactly as before and are what `@nativescript/core` currently installs (surfaced as `Application.uncaughtErrorEvent` / `discardedErrorEvent`). They are invoked only when no event listener called `preventDefault()`. New code should prefer `globalThis.addEventListener("error" | "unhandledrejection", ...)`.
+
+## Behavior details
+
+- Every error is reported exactly once: either the V8 message listener (synchronous throws), the rejection drain (once per run-loop turn, `kCFRunLoopBeforeWaiting`), or the boundary handler — never two of them for the same error.
+- A rejection that gets a handler before the end-of-turn drain is never reported (and produces no `rejectionhandled` either).
+- Rejection events carry the underlying V8 promise. `Promise.reject(...)` returns a `PromiseProxy`-wrapped object, so compare promises between events (`unhandledrejection` ↔ `rejectionhandled`), not against your proxy handle.
+- ObjC exceptions never unwind through live V8 frames: boundaries catch on the JS side and rethrow after scope teardown, and crash-mode throws are deferred to a clean run-loop frame. Preserve this invariant when touching the boundary code.

+# V8 10.3 → 14.9 migration notes
+
+Pinned version: **14.9.207.39** (`branch-heads/14.9`). The libraries are built by
+[NativeScript/v8-buildscripts](https://github.com/NativeScript/v8-buildscripts)
+and installed by `download_v8.sh`; the resurrecting-finalizer patch is described in
+[v8-resurrecting-finalizers.md](v8-resurrecting-finalizers.md).
+
+## Build configuration changes
+
+- `enable_ios_bitcode` and `use_xcode_clang` no longer exist upstream — removed.
+- `ios_deployment_target` must be a **string** (`"13.0"`, was a bare `13`).
+- `v8_enable_temporal_support=false` is now required. Temporal is implemented in Rust, and
+  enabling it emits Rust objects that reference a Rust sysroot (`__rust_alloc` and friends)
+  which we do not link. V8 10.3 had no Temporal, so disabling keeps parity.
+- arm64 **simulator** objects come out as `minos 14.0` regardless of the requested 13.0 —
+  that is an Apple floor for arm64 simulator slices, not a project setting.
+- `cppgc_enable_caged_heap=false` is required on iOS. See below.
+
+### The cppgc caged heap does not fit in an iOS address space
+
+Shipped in `v8-14.9.207.39-1` and `-2`, fixed in `-3`. **The symptom was a launch crash on
+some devices and not others** — an iPad Air died, an iPad Pro was fine — so it is worth
+recording how it happens.
+
+`cppgc_enable_caged_heap` defaults to **true on arm64** ("Enable heap reservation of size
+4GB") and, contrary to how the flags read, does *not* track
+`v8_enable_pointer_compression` — which we had already disabled. Enabling it forces cppgc's
+own pointer compression on, and that reservation path asks for **twice** the cage to satisfy
+alignment. `V8::Initialize()` calls `cppgc::InitializeProcess` unconditionally
+(`src/api/api.cc`), so every app reserved **8 GiB of 4 GiB-aligned address space** at startup
+whether or not it used cppgc — and nothing in the runtime used cppgc at all.
+
+iOS budgets *virtual address space* per process by device RAM. This is not about free memory:
+the reservation is `PROT_NONE`, costs no physical pages, and the iPad had plenty of RAM. It
+needs a contiguous, 4 GiB-aligned hole, and on a smaller device the process map has none once
+the binary, frameworks, dyld shared cache and malloc zones are placed. `CagedHeap` tries four
+hint addresses, then calls Oilpan's fatal OOM handler — an `EXC_BREAKPOINT` before a line of
+JS runs.
+
+Turning the cage off costs cppgc pointer compression (`Member<T>` becomes 8 bytes instead of
+4), the cppgc young generation, and a write-barrier fast path. It costs nothing in API:
+`CppHeap` and unified heap tracing are untouched, so the planned cppgc migration is
+unaffected. The alternative — the
+`com.apple.developer.kernel.extended-virtual-addressing` entitlement — was rejected because it
+makes every existing app edit its entitlements to survive a runtime upgrade, and any app that
+misses it crashes on launch on smaller hardware. It remains an option for apps that
+deliberately want large heaps.
+
+**Neither CI nor the simulator can catch this class of bug.** The simulator inherits macOS's
+address space and passes regardless; `-2` passed the full suite. Anything touching large
+virtual reservations has to be tried on constrained hardware.
+
+### New link-time dependencies
+
+14.9 pulls in third-party code that 10.3 did not. `libv8_third_party.a` is archived from
+everything under `out.gn/*/obj/third_party` **except** zlib and inspector_protocol (already
+vendored as `libzip.a` / `libcrdtp*.a`), and linked via `-lv8_third_party`. It covers abseil,
+simdutf and highway. Without it the link fails on `absl::hash_internal::*` and `simdutf::*`.
+
+`ninja` now emits **thin** archives (references, not objects), so the vendored `.a` files must
+be rebuilt from the `.o` files — a plain `cp` of `libinspector.a` silently produces a broken
+library.
+
+### Build from a clean `out.gn`
+
+The packaging step globs `obj/<target>/*.o`, and ninja never deletes outputs that a config
+change orphaned. Reusing an `out.gn` directory across V8 versions therefore archives stale
+objects: a first attempt here silently vendored 42 objects dated **2022** (from the previous
+10.3 build in the same directory) into `libv8_libbase.a`, `libv8_bigint.a` and `libcppgc_base.a`.
+It surfaced as `ld: duplicate symbol 'v8::base::OS::SignalCodeMovingGC()'`, because the archive
+held both the current `platform-darwin.o` and a stale `platform-macos.o`.
+
+Delete the output directory before building a new version. The same hazard applies to the Rust
+objects left behind by flipping `v8_enable_temporal_support` off, which is why the third_party
+glob excludes `*/rust/*`.
+
+## API changes applied to the runtime
+
+| Change | Sites | Migration |
+|---|---|---|
+| `Context::GetIsolate()` removed | 113 | `v8::Isolate::GetCurrent()` |
+| `External::New` / `External::Value()` take a type tag | 84 | `v8::kExternalPointerTypeTagDefault` |
+| `Get/SetAlignedPointerInInternalField` take a tag | 13 | `v8::kEmbedderDataTypeTagDefault` |
+| Interceptor callbacks return `v8::Intercepted` | 13 fns | see below |
+| `PropertyCallbackInfo::This()` removed | 43 | `Holder()` |
+| `ObjectTemplate/Object::SetAccessor` | 15 | `SetNativeDataProperty` |
+| Accessor callbacks take `Local<Name>` | 44 | was `Local<String>` |
+| `String::Value` deprecated | 2 | `String::ValueView` |
+| `GetInternalField` returns `Local<Data>` | 6 | `.As<v8::Value>()` |
+| `ScriptOrigin` no longer takes an `Isolate*` | 7 | drop the first argument |
+| `GetCreationContext[Checked]()` need an isolate | 9 | pass `v8::Isolate::GetCurrent()` |
+| `AccessControl` removed | 2 | drop the argument |
+| `ArrayBuffer::Detach()` needs a key | 1 | `Detach(Local<Value>())` — null key is allowed |
+| `V8Inspector::connect` needs a trust level | 3 | `kFullyTrusted` |
+| dynamic-import callback reshaped | 1 | `ScriptOrModule referrer` → `host_defined_options` + `resource_name` |
+| `V8ConsoleMessage::createForConsoleAPI` takes a span | 2 | `{args.data(), args.size()}` |
+
+### Interceptors: the one non-mechanical change
+
+Interceptor callbacks used to signal "I handled this" implicitly, by whether they set a return
+value. They now return `v8::Intercepted` explicitly. The conversion rule applied throughout was:
+
+- a path that called `GetReturnValue().Set*()` (or threw) → `return Intercepted::kYes`
+- a path that returned without setting one, **including falling off the end** →
+  `return Intercepted::kNo`
+
+That reproduces the old semantics exactly, and the fall-off-the-end case is load-bearing rather
+than an edge case: the swizzling definer depends on V8 still running the real `defineProperty`
+to install the JS accessor, and the setter interceptors depend on V8 still performing the
+ordinary store. Every getter here ends by setting a value (`kYes`); every setter and the definer
+fall through (`kNo`).
+
+Getting it backwards is silent in both directions: `kNo` where the old code intercepted lets V8
+continue the lookup up the prototype chain, and `kYes` where it did not suppresses the default
+operation entirely.
+
+Note the setter typedefs are inconsistent upstream — for **named** properties the current form is
+`NamedPropertySetterCallbackV2` (`PropertyCallbackInfo<Boolean>`), but for **indexed** properties
+it is the non-V2 `IndexedPropertySetterCallback` that takes `<Boolean>`, while the V2 spelling is
+the deprecated one taking `<void>`. Both current forms use `<Boolean>`.
+
+### V8 flags: set them before `V8::Initialize()`, and drop `--jitless`
+
+Two separate aborts, both inside `SetFlagsFromString` in `Runtime::CreateIsolate()`, before a
+line of JS ran:
+
+1. **Flags are frozen after initialization.** `V8::Initialize()` calls `FlagList::FreezeFlags()`
+   (`freeze_flags_after_init` defaults on), and changing a flag afterwards is fatal. The runtime
+   set its flags *after* `V8::Initialize()`; that call now happens first.
+2. **`--jitless` is read-only in lite-mode builds.** 14.9 declares it as
+   `DEFINE_BOOL_READONLY(jitless, true)` under `V8_JITLESS`, and setting a read-only flag is
+   also fatal. It is now omitted — lite mode already implies it, so behaviour is unchanged.
+
+Worth remembering that both failures look identical from the stack (`SetFlagsFromString` →
+`V8_Fatal` → `Abort`); the distinguishing detail is only in V8's message.
+
+### An empty `Local<Context>` is now a null dereference
+
+V8 commit `026ce4d1` (*"[api] Disallow empty context in CallDepthScope"*, Dec 2023 — after 10.3,
+before 14.9) removed the `if (!context.IsEmpty())` guard. `CallDepthScope` now runs
+`*Utils::OpenDirectHandle(*context)` unconditionally, so passing an empty context segfaults at
+address 0 instead of quietly skipping the context switch.
+
+This turns "call a context-needing V8 API without an entered context" from silently working into
+a crash. The exposure is anything reaching `isolate->GetCurrentContext()` — `tns::ToString`,
+`ToNSString`, `ToUtf16String` and raw `String::Utf8Value` all do, via V8's own
+`Utf8Value`/`ToString` internals. APIs taking an explicit `Local<Context>` are unaffected.
+
+It is invisible on strings: `Value::ToString` returns early when the value already is one, so a
+site only crashes once it converts a non-string. `JsV8InspectorClient::dispatchMessage` had
+`Locker` + `Isolate::Scope` + `HandleScope` but no `Context::Scope`, and survived until a JS
+domain handler returned `true` and the ack path converted the *numeric* request id.
+
+Entering the context at the thread entry point is the fix; the scope has to cover every
+conversion, not just the ones that call into JS.
+
+### `Local` is now trivially destructible
+
+Unused `Local<T>` locals now trip `-Wunused-variable`, which with `-Werror` is fatal. Five dead
+declarations were removed; they were genuinely unused, not merely unread.
+
+## The shipped headers now require C++20
+
+`v8config.h` went from `#if __cplusplus < 201703L` (C++17 is enough) to `#if __cplusplus <= 201703L`
+(C++17 is rejected). Any plugin whose sources include `v8.h` must therefore compile at c++20 or
+later, and several pin exactly `CLANG_CXX_LANGUAGE_STANDARD = c++17` in their
+`platforms/ios/build.xcconfig` — which sat precisely on the old floor.
+
+The app can't override this from `App_Resources/iOS/build.xcconfig`. The CLI merges every plugin's
+xcconfig *and* the app's into `plugins-{debug,release}.xcconfig`, and the merge is **first writer
+wins** — `XcconfigService.mergeFiles` deletes a key from the incoming file when the destination
+already has it. `mergeProjectXcconfigFiles` merges the plugins first and the app's file *last*, so
+for any key a plugin already set, the app's value is discarded outright; among plugins the winner
+is whichever comes first in dependency-resolution order. That merged file is then the **last**
+`#include` in `build-{debug,release}.xcconfig`, so it also beats the project-level setting in the
+pbxproj.
+
+Plugins are expected to declare c++20 themselves. Worth knowing that a single stale transitive
+plugin is enough to hold an entire app below the floor, and that the resulting error points at our
+headers rather than at the plugin that pinned the standard. An app that needs to force the floor
+regardless can assign `CLANG_CXX_LANGUAGE_STANDARD` *after* the `plugins-*.xcconfig` include in
+`build-{debug,release}.xcconfig`, which is the only layer that beats the merge.
+
+Both project templates now default to `gnu++20`; they were on `gnu++0x`, which is C++11 in the
+pre-ratification spelling and two floors below what `v8config.h` accepts. That fixes the baseline
+for an app carrying its own C++ or ObjC++ sources, but by the ordering above it is a project-level
+setting, so a plugin pinning a lower standard still wins over it.
+
+## The templates' C standard
+
+`GCC_C_LANGUAGE_STANDARD` is the only language setting the metadata generator reads:
+`build-step-metadata-generator.py` passes it straight through as clang's `-std=` when parsing the
+SDK, and never looks at `CLANG_CXX_LANGUAGE_STANDARD`. The templates were on `gnu99`, which
+predates C11; they are now on `gnu17`, Xcode's current default.
+
+This changes no metadata. Regenerating against the iOS 26.2 SDK under both standards produces
+byte-identical output — the binary, the umbrella header, and all 193 YAML modules. The only
+observable difference is one fewer spurious diagnostic, *"redefinition of typedef 'MPSImageBatch'
+is a C11 feature"*, which C11 and later allow.
+
+## Vendored inspector sources
+
+`NativeScript/inspector/src` is a copy of V8's inspector/base/debug headers, previously pinned to
+10.3. Because `libinspector.a` is now built from 14.9, keeping 10.3 headers would be an ABI
+mismatch, so the tree was re-vendored: 107 files from `v8/src`, 9 generated protocol headers from
+`out.gn/*/gen/src/inspector/protocol`, plus 7 newly-required headers.
+
+14.9's `src/common/globals.h` reaches abseil via `base/numbers/double.h` → `diy-fp.h` →
+`absl/numeric/int128.h`, so 11 abseil headers are vendored under `NativeScript/inspector/absl`
+(that directory is already on the header search path, so no project change was needed).
+
+Ten 10.3-era files no longer exist upstream and were left in place; nothing includes them now:
+`base/{cpu,functional,optional,safe_conversions*,v8-fallthrough}.h`,
+`common/allow-deprecated.h`, `debug/debug-type-profile.h`, `inspector/v8-webdriver-serializer.h`.
+
+## Test status
+
+`./run_tests.sh` on an iOS 18.5 simulator: **904 specs, 892 passing, 1 failing, 11 skipped.**
+All worker and teardown specs pass.
+
+The one failure, `TNS require :: should throw error if cant find node module`, is **not a
+migration regression**. `IsLikelyOptionalModule()` treats any bare specifier without a path
+separator as optional, so `require('nonExistingFileName.js')` yields a lazily-throwing
+placeholder rather than throwing, and the test never touches the result. That logic is
+version-independent and predates this work (it arrived with ESM support in `e72977ab`), so it is
+left alone here rather than changed as a side effect of the V8 upgrade.
+
+### Accessors that are inherited need a real accessor pair
+
+Three separate failures had one root cause: **property callbacks can no longer see the
+receiver**, and `SetNativeDataProperty` is not a drop-in replacement for `SetAccessor` on an
+object that is inherited from.
+
+- `ClassBuilder`'s `super` (on the implementation object, which instances inherit) and
+  `Reference.value` (on a `PrototypeTemplate`) both need the receiver, and `Holder()` gives the
+  prototype instead. Both are now function-backed accessors, whose `FunctionCallbackInfo::This()`
+  still returns the receiver.
+- Static properties on constructor functions behaved worse: `SetNativeDataProperty` installs
+  something data-like, so `Derived.baseProperty = x` shadowed the base's property with an own
+  data property and never reached the native setter. Now installed with `SetAccessorProperty`.
+
+The rule of thumb: if an accessor lives on anything that is inherited from — a prototype
+template, a base constructor, an implementation object — use `SetAccessorProperty` with
+function-backed getter/setter. `SetNativeDataProperty` is only safe on instance templates,
+where `Holder() == This()` and nothing inherits it.
+
+## Outstanding
+
+Nothing blocking. One follow-up:
+
+- `DisposerPHV.{h,mm}` is now dead code -- `Isolate::VisitHandlesWithClassIds` no longer exists,
+  so the visitor can never be driven. Its logic moved to `ObjectManager::DisposeAllRegistered()`.
+
+### Behavioural parity traps in the accessor rewrite
+
+Two places where the new APIs quietly change semantics unless the old values are carried over
+deliberately. Neither is covered by a test, so both would have shipped silently:
+
+- **Accessor attributes.** `Object::SetAccessor` defaulted to `PropertyAttribute::None`;
+  `SetAccessorProperty` takes the attributes explicitly. Passing `DontEnum` for `super` (an easy
+  assumption, since it looks internal) removes it from `Object.keys()` and `for...in` on the
+  implementation object. The defaults are preserved instead.
+- **`ArrayBuffer::Detach`.** The deprecated `Detach()` returned void and could not report
+  failure. The replacement returns `Maybe<bool>` and is `V8_WARN_UNUSED_RESULT`, so it invites a
+  `.Check()` — which **aborts the process** when the buffer has an `[[ArrayBufferDetachKey]]`
+  that does not match. This is on the worker `postMessage` transfer path, so the result is
+  discarded rather than checked.
+
+### An intermittent worker/notification deadlock
+
+Two runs during this work hung for ~10 minutes instead of finishing. Sampling the stuck process
+showed a lock-order inversion that does not involve any of the above:
+
+- the main thread, inside a posted notification (`___CFXRegistrationPost` →
+  `ArgConverter::MethodCallback`), blocked acquiring a worker isolate's `v8::Locker`;
+- worker threads, running JS that dispatched an ObjC method, blocked in
+  `initializeNonMetaClass` on the ObjC runtime's class-initialization lock.
+
+It has not reproduced in the three runs since, so it is timing-dependent. It is recorded here
+because the symptom (suite hangs with no crash report, last log line a spec well before the
+worker tests) is otherwise very hard to place.
+
+### Teardown disposal
+
+`Isolate::VisitHandlesWithClassIds` was removed upstream, so wrappers can no longer be found by
+walking V8's handles. `Caches` now keeps a `weak_ptr` registry of every handle
+`ObjectManager::Register()` hands out -- weak, so tracking never keeps a wrapper alive, and
+compacted whenever it would grow so collected entries do not accumulate.
+`ObjectManager::DisposeAllRegistered()` walks that registry at teardown, then disposes the
+`Caches` collections that used to carry the `DataWrapper` class id (`CtorFuncs`,
+`ProtocolCtorFuncs`, `CFunctions`, `PrimitiveInteropTypes` and the three interop ctor handles).
+`~Caches()` cleared those maps but never disposed their wrappers, so they leaked too.
+
+It has to enter the isolate itself: `~Runtime` holds a `Locker` but never enters, and creating
+handles without that segfaults in `HandleScope::CreateHandle`. The same applies to
+`Worker::SetWorkerId`, which runs after `Runtime::Init()` has unwound its own `Isolate::Scope`.

+# Restoring resurrecting finalizers on V8 14.9
+
+Status: **exercised by the runtime suite** (904 tests, 0 failures); the flag-driven stress
+scenarios below are still unrun
+Patch: [`v8_resurrecting_finalizers.patch`](v8_resurrecting_finalizers.patch) — 6 files, +184/-3,
+against V8 **14.9.207.39** (`branch-heads/14.9`). The patch and the pinned
+version live in [NativeScript/v8-buildscripts](https://github.com/NativeScript/v8-buildscripts).
+Built clean for `arm64-iphonesimulator` (lite mode, no sandbox, no pointer compression).
+
+Also applies unmodified to 14.4, 14.5 and 14.6; on 14.8+ the `heap-symbols.h` hunk needs
+re-alignment (whitespace only).
+
+## Why
+
+`ObjectManager::FinalizerCallback` ([ObjectManager.mm:34](NativeScript/runtime/ObjectManager.mm#L34))
+reads the dying object's internal fields and may **refuse** disposal by re-arming its
+handle (`ClearWeak()` + `SetWeak()`). That requires `v8::WeakCallbackType::kFinalizer`,
+which upstream removed one day after our pinned 10.3.22:
+
+| Change | Commit | Landed in |
+|---|---|---|
+| `kFinalizer` API removed | `2ae2aa92` | ~10.3.24 |
+| GC machinery removed | `cb92ed09` | ~10.3.27 |
+| Node state machine simplified | `015632a0` | ~10.3.46 |
+
+On stock 14.x the pattern is not merely unsupported but fatal: the handle slot is zapped
+to `0xCA11` before the callback runs, and `CHECK_WITH_MSG(Node::FREE == node->state(), ...)`
+crashes if a callback re-arms instead of resetting. Re-arming a `kParameter` handle is not
+a workaround — that callback only fires once V8 has already committed to the object's death.
+
+This patch exists to buy time: it keeps the current ownership semantics working on a modern
+V8 while the reachability-based redesign in
+[RESURRECTION_TO_REACHABILITY.md](RESURRECTION_TO_REACHABILITY.md) is proven out. It is
+deliberately **narrower** than what upstream removed.
+
+## Scope: major GC only
+
+Upstream supported finalizers in both young and full GC. This patch does not.
+
+- **Young GC (scavenger + minor mark-sweep): finalizer handles are strong roots.** They are
+  visited by `IterateYoungStrongAndDependentRoots()` and skipped by `ProcessWeakYoungObjects()`.
+  A young collection never finalizes; it just promotes. Collection is deferred to the next
+  full GC.
+- **Full GC: the keep-alive pass runs**, objects are queued, and callbacks fire after the pause.
+
+This is what deletes the hardest part of a faithful revert. Upstream's young-generation
+hooks lived in `MinorMarkCompactCollector`, which no longer exists (replaced by
+`minor-mark-sweep.cc`), so a faithful port would have had to re-derive them. Both young
+collectors call the same two `GlobalHandles` entry points, so treating finalizers as strong
+is one change covering both, and `scavenger.cc` / `minor-mark-sweep.cc` are untouched.
+
+## How it works
+
+**1. Keep-alive** (`mark-compact.cc`, end of `MarkLiveObjects()`). After the final marking
+closure, `IdentifyDeadFinalizerHandles()` queues every finalizer handle whose object is
+unmarked, `IterateFinalizerHandlesAsRoots()` visits them, and the marking closure
+(`MarkTransitiveClosureFixpoint()`, falling back to `MarkTransitiveClosureLinear()`)
+re-drains the worklists.
+
+**2. Pending bit** (`global-handles.cc`). A queued node carries a `pending_finalizer` flag
+(bit 5 of `flags_`, previously unused) and is added to `pending_finalizers_`. While set, the
+node is visited by `IterateStrongRoots()`, and re-identification is suppressed. The bit —
+not the queue — is the source of truth: entries are re-checked before invocation, because GC
+epilogue callbacks run before the drain and may reset a queued handle out from under it.
+
+**3. Post-pause invocation** (`GlobalHandles::PostGarbageCollectionProcessing`). Callbacks
+run from the GC epilogue via `InvokeExternalCallbacks` — *not* from the first-pass phantom
+path, which runs in-pause and forbids allocation. The drain is wrapped in
+`AllowJavascriptExecution`; see below for why that is required rather than incidental.
+
+**4. Lifting `DisallowJavascriptExecution`.** `Heap::CollectGarbage` holds one across the
+*entire* collection, epilogue included — `heap.cc`, "JS execution is not allowed in any of
+the callbacks" — and `InvokeExternalCallbacks()` re-enables allocation
+(`AllowGarbageCollection`) but deliberately not JS, asserting on entry that JS is disallowed.
+Entering JS from a callback therefore hits
+
+```cpp
+// src/execution/execution.cc, Invoke()
+if (!AllowJavascriptExecution::IsAllowed(isolate)) {
+  GRACEFUL_FATAL("Invoke in DisallowJavascriptExecutionScope");
+}
+```
+
+and aborts the process. **This is a behavioural change from 10.3**, where
+`InvokeSecondPassPhantomCallbacks()` ran under an explicit `AllowJavascriptExecution`.
+
+The runtime depends on the 10.3 behaviour and cannot avoid it:
+`ObjectManager::FinalizerCallback` → `DisposeValue` → `[target release]` runs `-dealloc`, and
+any JS-backed override that teardown reaches — a JS `UIView` subclass being removed from its
+superview, a delegate, a block — re-enters JS through `ArgConverter::MethodCallback`. So the
+patch lifts the scope around the finalizer drain **only**: `InvokeSecondPassPhantomCallbacks()`
+below it still asserts JS is disallowed, so the scope is closed before it runs.
+
+Both scopes are live in release builds. Only the `…DebugOnly` aliases generated in
+`assert-scope.h` compile away, and neither `Heap::CollectGarbage` nor this patch uses those.
+
+The Android runtime shares this patch but does not depend on the lift: its finalizer makes a
+single runtime-internal JNI call (`makeInstanceWeakAndCheckIfAlive`) and Java has no
+synchronous destructor that could re-enter JS.
+
+The public enum gains a third value; `api.cc` needs no change (it passes the type through,
+and the only switch is in `Node::MakeWeak`).
+
+## Invariants
+
+These are the things that make it correct. Breaking any of them is a use-after-free, not a leak.
+
+1. **The keep-alive must run at the end of `MarkLiveObjects()`, inside the cppgc atomic pause.**
+   Not in `ClearNonLiveReferences()`. At the chosen point the cppgc marker is still live
+   (`CppHeap::FinishMarkingAndProcessWeakness()` has not run), so the re-drained closure
+   still pushes to cppgc via `VisitCppHeapPointer` → `AdvanceMarking`. A resurrected wrapper whose
+   JS properties reach cppgc-managed objects therefore marks correctly. Moving this block after
+   `CollectGarbage:534` silently drops those pushes and sweeps live cppgc objects.
+
+2. **The keep-alive must precede all weakness processing.** Everything that consumes liveness —
+   phantom handles, ephemerons, `WeakRef`/`FinalizationRegistry`, map-transition pruning, code
+   flushing — lives in `ClearNonLiveReferences()`, which runs after. Every such pass must observe
+   the resurrected closure as live.
+
+3. **The pending bit must never survive into a reallocated node.** Cleared in `ClearImplFields()`
+   (release path), `ClearWeakness()` and both `MakeWeak()` overloads (re-arm path). A freed node
+   carries a zapped location; visiting it as a root would crash.
+
+4. **A finalizer callback must reset or re-arm its handle.** Enforced by `CHECK_WITH_MSG` after
+   invocation. Doing neither leaves the handle rooted forever.
+
+Two supporting facts, verified in 14.9 and worth re-checking on any upgrade: marking iterates
+global handles via `IterateStrongRoots` (`SkipRoot::kWeak`), so pending nodes are protected
+during a nested GC; root *updating* uses `IterateAllRoots`, a single pass over `NORMAL||WEAK`,
+so a pending node's slot is updated exactly once after evacuation.
+
+## Deliberate deviations from upstream's original
+
+- **No `PENDING` state, no `NEAR_DEATH` for finalizers.** 14.9's `NodeState` is 2 bits with all
+  four values used; a separate flag bit avoids widening it, and keeps finalizer nodes out of the
+  `NEAR_DEATH` accounting in `UpdateListOfYoungNodesImpl()`.
+- **Pending nodes are strong roots, not weak retainers.** Upstream left a `NEAR_DEATH` finalizer
+  node weak while its callback ran, which leaves the object unprotected against a GC nested
+  inside the callback. Rooting it is stricter.
+- **`ResetWeakNodeIfDead()` reports finalizer handles alive rather than `UNREACHABLE()`.**
+  Client isolates of a shared space get their own `IterateWeakRootsForPhantomHandles()` pass
+  (`mark-compact.cc:3166`) that the keep-alive does not cover. Reporting alive defers collection
+  by a cycle in that exotic case instead of crashing.
+- **`Node::PostGarbageCollectionProcessing` keeps upstream's name deliberately.**
+  `tools/cfi/ignores.txt` blocklists `*GlobalHandles*PostGarbageCollectionProcessing*` because
+  `weak_callback_` is invoked on the wrong type. Renaming it breaks CFI builds.
+
+## Known hazard: a finalized object can outlive its native half
+
+`IdentifyDeadFinalizerHandles()` snapshots the dead set *before* `IterateFinalizerHandlesAsRoots()`
+and the re-drain, so the queue is built against pre-resurrection marking. If two wrappers are
+both JS-unreachable and one references the other, **both** are queued:
+
+- `n1` holds `n2`; neither is reachable from a JS root, so both are queued.
+- The keep-alive marks `n1`'s whole closure — `n2` included — live, so nothing is swept.
+- `n2`'s callback runs first and disposes: `[N2 release]`, wrapper deleted.
+- `n1`'s callback finds `IsGcProtected()` and re-arms.
+
+`n1` comes back holding a JS object whose native half is gone. `DisposeValue` does neuter the
+husk (`delete wrapper` then `tns::DeleteValue`, which sets internal field 0 to `Undefined`), so
+it is not a dangling `BaseDataWrapper*` — but consumers that read the field without checking,
+`Pointer.cpp` among them, will read `Undefined` as an `External` and dereference it.
+
+**This is not fixable by deferring the release or by re-checking liveness after the drain.**
+Every queued node is rooted by `IterateFinalizerHandlesAsRoots()` and treated as a strong
+retainer for the rest of the cycle, so immediately after the GC *every* disposed object still
+looks alive; the check cannot separate "alive because a referrer revived" from "alive because
+it was rooted for its own finalization". Waiting a cycle does not converge either: `n1` re-arms
+weak, so the next `IdentifyDeadFinalizerHandles()` finds both unmarked again and re-queues the
+same pair.
+
+Nor is it fixable by making `GcProtect()` a strong root instead of a disposal veto. Disposal
+here is driven by whether *native* still needs the object, not by JS reachability, and that is
+precisely what lets a JS↔ObjC cycle collect at all: an unprotected object is released even
+though surviving JS still references it. Turning protection into an opaque strong root would
+convert every such cycle into a permanent leak.
+
+The real fix is to stop expressing liveness with roots and express it by *tracing* — `CppHeap`,
+`v8::Object::Wrap`/`Unwrap`, `TracedReference` and cppgc `Trace()`, which mark *through* the
+embedder graph and so collect cross-heap cycles without resurrection. That is
+[RESURRECTION_TO_REACHABILITY.md](RESURRECTION_TO_REACHABILITY.md). Note that the intermediate
+option is gone: `EmbedderRootsHandler::IsRoot()`, which used to let an embedder declare a
+`TracedReference` a root per-GC, no longer exists in 14.9 — only `ResetRoot`/`TryResetRoot`
+remain.
+
+Until then, the husk has defined behaviour: `tns::GetValueOrReport()` (Helpers) applies
+the `releasedObjectPolicy` runtime config (ns:runtime, docs/ns-builtin-modules.md) on a
+missing wrapper — default `"report"` no-ops the operation and fires the
+`releasednativeaccess` global event with the touch site's stack; `"throw"` raises a
+catchable JS `ReferenceError` — and every internal-field read that could otherwise see a
+neutered field goes through it — `Pointer.cpp`'s methods, `ExtVector.cpp` toString,
+`Interop::SetStructPropertyValue` (both struct cases), `MetadataBuilder::GetStructData` and
+both struct property interceptors, the two `InteropTypes.mm` argument readers, and the
+`Reference.cpp` accessors (`SetValueCallback`, `GetWrappedPointer`, `GetDataPair` → indexed
+get/set, toString). Regression spec: *"throws instead of crashing when touching a released
+object through a resurrected parent"* in `GCFinalizerTests.js`.
+
+Two facts worth knowing when reasoning about which objects can husk:
+
+- `Pointer`/`interop.alloc` objects never husk at runtime — `Caches::PointerInstances`
+  holds them behind strong persistents, so their finalizers cannot fire. Struct instances
+  and `Reference`s are held only by their own weak finalizer handle and do husk.
+- Only the TypeScript `__extends` path installs the retain/release swizzles that drive
+  `GcProtect()`; a class from plain `.extend()` is never protected, so its instances are
+  disposed rather than resurrected when natively retained.
+
+## Verified so far
+
+- **Runs.** The TestRunner suite is green against the patched V8 — 904 tests, 0 failures,
+  0 errors, 11 skipped — including the GC tests named at the end of the next section.
+- **Compiles.** Full V8 build for `arm64-iphonesimulator` at 14.9.207.39, exit 0, no warnings
+  in the patched files.
+- Applies cleanly to pristine 14.9.207.39.
+- Public API surface compiles: a standalone TU using `SetWeak(..., kFinalizer)`, `Get()` inside
+  the callback, and both the re-arm and reset paths passes `clang++ -fsyntax-only -std=c++20`.
+- Adds no clang-format violations (mark-compact.cc's 30 are pre-existing).
+- No exhaustive switch over `WeakCallbackType` exists outside `Node::MakeWeak`, so adding the
+  enum value breaks no other translation unit.
+
+## Still unverified
+
+The runtime suite passes against the patched V8, which drives the resurrection path in anger —
+see *"Worker instance should not be garbage collected if the worker thread is alive"* below.
+Everything in this section is narrower: it needs a V8 run under specific flags, and the suite's
+default configuration reaches none of it.
+
+1. **Re-running the marking closure after `EnterProcessGlobalAtomicPause()`.** The
+   closure is asserted empty at that point and this patch pushes new roots and re-drives it. The
+   `CHECK(IsCppHeapMarkingFinished(...))` after the second drain is the tripwire. Run under
+   `--stress-incremental-marking` and `--stress-concurrent-marking`. **Highest-value test.**
+2. **Resurrect-then-rearm, end to end.** A finalizer that re-arms N times then resets, across
+   repeated `--expose-gc` major GCs, under `--verify-heap`. Confirms the callback site, the
+   un-zapped slot through `MakeWeak`'s `CHECK_NE(object_, kGlobalHandleZapValue)`, and the
+   `CHECK_WITH_MSG` contract.
+3. **Resurrected object reaching a cppgc object.** Give a resurrected wrapper a JS property
+   chain to a cppgc-managed wrapper and confirm it is not swept. This is invariant 1's test; it
+   is the failure mode with no loud assertion.
+4. **Young-generation path.** A finalizer handle on a young object: confirm scavenge promotes it
+   rather than finalizing, and that `IncrementNodesDiedInNewSpace` accounting stays sane.
+5. **Nested GC inside a finalizer callback.** Allocate heavily in the callback; confirm no
+   double-invocation and no collection of the object under inspection.
+
+The runtime's existing GC tests are the acceptance gate for the patch as the runtime uses it,
+and they pass — in particular *"Worker instance should not be garbage collected if the worker
+thread is alive"*, which exercises the `WorkerWrapper` resurrection site directly.
+
+## Upgrade cost
+
+Every V8 bump requires re-checking the four invariants above, since three of them are about
+*where* the block sits relative to phases that upstream reorders freely. This is intermediate
+scaffolding with a real carrying cost — it is cheaper than a faithful revert, not free.

+# `ns:` builtin modules
+
+Cross-runtime contract for exposing runtime-provided modules to application
+code. This document is the specification both the iOS and Android runtimes
+implement; a capability must behave identically on both platforms before it
+ships in a stable release.
+
+## The scheme
+
+Builtin modules live under the URL-style `ns:` scheme, mirroring Node's
+`node:` prefix:
+
+```js
+// CommonJS
+const util = require("ns:util");
+
+// ES modules
+import util, { inspect } from "ns:util";
+const util2 = await import("ns:util");
+```
+
+Rules:
+
+- `ns:` specifiers are resolved by the runtime **before any filesystem or
+  npm resolution**. They can never be shadowed by a file, a path mapping, or
+  a package — and conversely, a file named `ns:util` is not reachable.
+- Resolution of an unknown builtin fails synchronously with an `Error` whose
+  message is exactly `No such built-in module: ns:<name>` (matching Node's
+  wording for familiarity).
+- A builtin module is a **singleton per JS realm** (main context and each
+  worker get their own instance). `require("ns:util")` twice returns the same
+  object; the CJS exports object and the ESM namespace expose the same
+  underlying values (ESM additionally provides the exports object as
+  `default`).
+- There is no bare-specifier fallback: `require("util")` is **not** an alias
+  for `require("ns:util")`. The unprefixed name continues to resolve to npm
+  packages as it always has.
+- Builtin exports are frozen. Apps patch behavior by wrapping, not by
+  mutating the runtime's module.
+
+## Modules
+
+### `ns:util` (v1)
+
+| export | description |
+|---|---|
+| `inspect(value[, options])` | Formats any value for human consumption: depth-limited, output-capped, cycle-safe, never invokes getters (except a guarded `error.stack` read and custom `toString` overrides, which are honored). `options.depth` (number) overrides the default depth of 2. Other option keys are reserved. |
+| `format(fmt, ...args)` | Node-style printf formatting: `%s`, `%d`, `%i`, `%f`, `%j`, `%o`, `%O`, `%%`. Extra arguments are appended space-separated, objects rendered via `inspect`. When `fmt` is not a string or contains no substitutions, all arguments are formatted and joined with spaces. `console.*` routes its arguments through this, so `console.log("%d apples", 3)` works. |
+
+**Stability caveat (verbatim from Node's contract):** the output of `inspect`
+(and therefore `format`'s object rendering) may change between runtime
+versions for readability; it is intended for humans and must not be parsed
+programmatically.
+
+### `ns:runtime` (v1)
+
+Runtime-level configuration. Keys, value domains, and scope are defined and
+validated natively; the module surface is a thin frozen wrapper.
+
+| export | description |
+|---|---|
+| `setConfig(key, value)` | Sets a runtime config key. Throws `TypeError` on an unknown key, an invalid value, or (for process-wide keys) when called from a worker isolate. |
+| `getConfig(key)` | Returns the current value of a config key. Throws `TypeError` on an unknown key. Readable from any isolate. |
+
+Config keys:
+
+| key | values | scope | default |
+|---|---|---|---|
+| `releasedObjectPolicy` | `"report"` \| `"throw"` | process-wide (main-isolate writes only; read live by every isolate) | `"report"` |
+
+`releasedObjectPolicy` controls what happens when JS touches a wrapper whose
+native counterpart has already been released (a state a resurrected object can
+expose — see the iOS runtime's `docs/knowledge/v8-resurrecting-finalizers.md`):
+
+- `"report"` (default): the operation no-ops — reads produce `undefined`,
+  writes are skipped, `toString` yields a `<Pointer: released>`-style
+  placeholder — and a cancelable `releasednativeaccess` event fires on
+  `globalThis` (`event.error` carries a `ReferenceError` whose stack names the
+  touch site; `event.operation` names the API surface, e.g.
+  `"struct field assignment"`). Reports are deduplicated per released object.
+  In debug builds the event's default action is a `console.warn`; a listener
+  that handles the report suppresses it with `preventDefault()`.
+- `"throw"`: the touch throws a catchable `ReferenceError` synchronously, and
+  no event fires.
+
+## `node:` compatibility shims
+
+The same registry serves the `node:` scheme with **compatibility shims** so
+npm packages that require Node builtins by their prefixed names can run
+unmodified where a shim exists:
+
+- A shim implements a documented **subset** of the corresponding Node module's
+  API, backed by `ns:` modules. Unimplemented members are simply absent
+  (so `typeof util.promisify === "function"` feature-checks behave
+  correctly); they are never present-but-throwing.
+- **One source file per specifier.** A shim is its own module that consumes
+  the `ns:` module it adapts through the internal require, and it owns *all*
+  the adaptation — argument shapes, option names, aliases, anything that has
+  to track Node. A standard `ns:` module never contains compatibility code
+  and never knows a shim exists.
+- Shims are **lazy**: a shim's source is only evaluated when its specifier is
+  first resolved, so an app that never touches the `node:` scheme never pays
+  for one.
+- `node:` modules with no shim fail with the same error shape:
+  `No such built-in module: node:<name>`.
+- **Bare specifiers are untouched**: `require("util")` resolves through npm
+  as it always has (many apps bundle the `util` polyfill package). Only the
+  explicit `node:` prefix reaches the shim registry, so existing apps cannot
+  break. Bundler-level aliases (webpack/rollup) continue to work and take
+  precedence at build time.
+- A shim is always a **distinct module object** from any `ns:` module, even
+  when every member is re-exported unchanged. `ns:` modules may grow runtime-specific
+  members freely; a `node:` shim only ever gains members that track Node's
+  actual API. This mirrors how Bun (`bun:*`), Deno (`Deno.*`/JSR) and
+  Cloudflare (`cloudflare:*`) all keep their own surface strictly apart from
+  their `node:` compat layer.
+- Shims ship on both runtimes under the same parity rule as `ns:` modules.
+
+### v1 shims
+
+| module | exports | notes |
+|---|---|---|
+| `node:util` | `inspect`, `format` | Re-exports `ns:util`'s members unchanged (`nodeUtil.inspect === nsUtil.inspect`) from a **distinct, separately frozen module object**. Documented as partial. |
+
+Candidates for future shims, in rough order of ecosystem demand:
+`node:events` (EventEmitter), `node:path` (pure JS), `node:buffer`,
+`node:process` (subset). Each requires a spec update here first.
+
+## The internal require
+
+Builtin modules reach each other — and only each other — through an internal
+`require` the runtime provides to every builtin source:
+
+- It resolves **builtin specifiers only**. A path, a package name or any other
+  specifier is not reachable from a builtin; an unregistered builtin name
+  throws the same `No such built-in module: <specifier>` an app sees.
+- It materializes the target module on first use and returns the realm's
+  singleton afterwards, which is what makes shims lazy.
+- Requiring a module that is still being built throws rather than recursing,
+  so a dependency cycle between builtins is a loud error and not a hang.
+
+This is the mechanism shims are built on, so it is normative: both runtimes
+provide it.
+
+## Adding a builtin module
+
+- The name is a short, lowercase identifier (`ns:util`, `ns:timers`, ...).
+- One module, one source file, one registry entry — including shims.
+- New modules and new exports require this document to be updated first and
+  an implementation on both runtimes before a stable release; a module may
+  ship on one platform behind a documented "experimental, iOS-only" (or
+  Android-only) note in between.
+- Internal runtime machinery must never be reachable through the scheme:
+  the registry distinguishes public modules from internal builtins, and only
+  public ones resolve (Node's `canBeRequiredByUsers` split).
+
+## Source-text modules: deliberately not supported
+
+Builtins are classic function bodies, not ES modules, on both runtimes. If
+cross-builtin code sharing is ever needed, the first answer is bundling at
+generation time (author as ESM, emit function bodies); runtime source-text
+builtin modules (Node's `kSourceTextModule`) are justified only by a concrete
+need for live module semantics (TLA, live bindings, cyclic imports), which no
+current or planned builtin has. Revisit here before building either.
+
+## iOS implementation notes (non-normative)
+
+Builtin modules are function-body builtins (`NativeScript/runtime/js/`,
+see the README there) compiled via the RuntimeBuiltins table. The `ns:`
+resolver intercepts specifiers in the CommonJS require path and in the ES
+module resolve/dynamic-import callbacks; ESM consumption is served by a
+synthetic module whose exports are populated from the same per-realm exports
+object. The internal require is a fixed parameter of the builtin function
+wrapper (`exports`, `require`, `module`, `binding`, `primordials`).
+
+iOS also keeps a pre-registry `node:url` polyfill (`fileURLToPath`,
+`pathToFileURL`) that predates this document. It is compiled from module
+source inside the ES module resolver and is therefore reachable through
+`import` only, not through `require()`.

+# Performance API
+
+The runtime implements the WHATWG/WinterTC-standard Performance surface: [High
+Resolution Time](https://w3c.github.io/hr-time/), [User Timing Level
+3](https://w3c.github.io/user-timing/) and the [Performance
+Timeline](https://w3c.github.io/performance-timeline/) with
+`PerformanceObserver`.
+
+## Surface
+
+Globals (own, writable, enumerable, configurable properties of `globalThis`,
+in main and worker isolates alike): `performance`, `Performance`,
+`PerformanceEntry`, `PerformanceMark`, `PerformanceMeasure`,
+`PerformanceObserver`, `PerformanceObserverEntryList`.
+
+- `performance.now()` — double milliseconds since the isolate's time origin,
+  monotonic (V8 platform clock, `mach_absolute_time`-based: it does not tick
+  while the device is asleep), full double precision with no coarsening.
+- `performance.timeOrigin` — readonly accessor; wall-clock milliseconds since
+  the Unix epoch, sampled once when the isolate's runtime is created. Each
+  worker gets its own time origin at worker-thread start, so
+  `timeOrigin + now()` approximates `Date.now()` per isolate while the device
+  stays awake; it drifts behind after device sleep (the monotonic clock does
+  not tick then) and diverges under wall-clock adjustments.
+- `performance.toJSON()`, `Symbol.toStringTag`, and `Performance extends
+  EventTarget` per spec; `performance`, `PerformanceEntry`,
+  `PerformanceMeasure` and `PerformanceObserverEntryList` are not
+  user-constructible (`new` throws `TypeError`); `new PerformanceMark(name,
+  options)` is constructible per spec but does not buffer the entry.
+- User timing: `mark(name, {startTime, detail})`, `measure(name,
+  startOrOptions, endMark)` with the full Level 3 options algebra (`{start,
+  end, duration, detail}`, mark names or timestamps, over-/under-constraint
+  errors), `clearMarks(name?)`, `clearMeasures(name?)`.
+- Timeline: `getEntries()`, `getEntriesByType(type)`, `getEntriesByName(name,
+  type?)` return copies sorted chronologically by `startTime` (stable for
+  ties).
+- Observers: `new PerformanceObserver(cb)`, `observe({entryTypes})` or
+  `observe({type, buffered})`, `disconnect()`, `takeRecords()`, static frozen
+  `PerformanceObserver.supportedEntryTypes === ["mark", "measure"]`.
+
+## Architecture
+
+All spec logic lives in the `internal/performance.js` builtin
+(`NativeScript/runtime/js/performance.js`), which is deliberately portable:
+the native side hands it only `{ now(), timeOrigin }`, so the same file is
+meant to be reused unchanged by the Android runtime against an equivalent
+binding bag.
+
+The native clock is owned by `Runtime` (`Runtime::PerformanceNowMillis()`,
+`Runtime::TimeOriginMillis()`, captured in `Runtime::CreateIsolate`) and
+exposed to native callers through `tns::Performance::NowMillis(isolate)`
+(`NativeScript/runtime/Performance.h`). Any future native producer of
+JS-visible timestamps — `requestAnimationFrame` in particular — must read the
+clock through that hook rather than sampling its own, so every timestamp
+shares `performance.timeOrigin` as its base.
+
+## Deviations from the specs
+
+- **Buffers are unbounded.** Per spec for user timing. `detail` is
+  structured-cloned at entry creation (per spec — an uncloneable `detail`
+  throws the `DataCloneError`-named error), so entries hold snapshots, but a
+  long-lived app marking in a loop should still clear entries periodically.
+- **Observer callbacks run from a microtask**, not a queued task: delivery is
+  asynchronous relative to `mark()`/`measure()` but precedes timer callbacks
+  scheduled in the same turn. Callback exceptions are routed to
+  `reportError`, so one throwing observer does not starve the others.
+- **No `DOMException`.** Errors the specs express as `DOMException` — the
+  `SyntaxError` for a missing mark name, the `InvalidModificationError` for
+  switching an observer between the `entryTypes` and `type` forms — are
+  `Error` instances with `name` patched. `err.name` checks work;
+  `instanceof DOMException` does not.
+- Browser-only surface is absent: no resource/navigation timing, no
+  `eventCounts`, and no `PerformanceTiming`-attribute resolution in
+  `measure()`.

+# structuredClone
+
+The runtime exposes the WHATWG [`structuredClone(value, options)`](https://html.spec.whatwg.org/multipage/structured-data.html#dom-structuredclone) global. It performs a deep, structure-preserving copy of `value` using V8's structured clone serializer — the same one worker `postMessage` uses — optionally taking ownership of `ArrayBuffer`s named in `options.transfer`.
+
+```js
+const clone = structuredClone({ when: new Date(), tags: new Set(["a"]) });
+
+const buffer = new ArrayBuffer(1024);
+const moved = structuredClone(buffer, { transfer: [buffer] });
+buffer.byteLength; // 0 — the memory now belongs to `moved`
+```
+
+## Surface
+
+`structuredClone(value)` returns a clone of `value`. `structuredClone(value, { transfer })` additionally transfers every `ArrayBuffer` in `transfer`.
+
+- `value` is required; calling with no arguments throws a `TypeError`.
+- `options` may be `undefined` or `null` (both mean "no transfer"); anything else must be an object, or a `TypeError` is thrown.
+- `options.transfer` is a WebIDL sequence: any object with a callable `Symbol.iterator` works (an array, a `Set`, a generator). A non-iterable value — including a string primitive — throws a `TypeError`.
+
+Cloneable: every primitive value except symbols — numbers (including `-0`, `NaN` and the infinities), strings, booleans, `BigInt`, `null` and `undefined`; plain objects and arrays; `Date`, `RegExp`, `Map`, `Set`, `Error`; `Boolean`/`String`/`Number` wrapper objects; `ArrayBuffer`, every typed array and `DataView`.
+
+The clone preserves the shape of the graph, not just the values: an object referenced twice in the input is a single object referenced twice in the output, and cycles round-trip. Prototypes do not survive — a class instance clones to a plain object with the same own properties. Getters are invoked during cloning and their result is stored as a plain data property. Property insertion order is preserved.
+
+`SharedArrayBuffer` is **shared, not copied**: the clone is a second `SharedArrayBuffer` over the same memory, so writes through either are visible through the other.
+
+Not cloneable — each throws (see the deviations below): functions, symbols, `WeakMap`/`WeakSet`/`WeakRef`, `Promise`, and every native/interop object (ObjC wrappers, pointers, function references), which have no serialized form.
+
+## Transfer semantics
+
+Listed buffers are validated before anything is serialized: each entry must be an `ArrayBuffer`, must not already be detached, must be detachable, and must appear at most once. A violation throws before the source buffers are touched, so a rejected call never leaves a half-transferred graph behind.
+
+On success the memory changes hands rather than being copied: the source buffer is detached (`byteLength` becomes 0, and every typed array over it becomes zero-length) and the clone receives the original backing store. A transferred buffer need not appear inside `value` at all; a buffer reached through a typed array in `value` is transferred as a unit, so the cloned view sees the original bytes.
+
+## Worker `postMessage`
+
+`structuredClone` and worker `postMessage` run on the same serialization core, so everything above — which types clone, graph identity, cycles, `SharedArrayBuffer` sharing — holds for messages too. `postMessage` takes the same transfer list as a second argument:
+
+```js
+worker.postMessage({ pixels: buffer }, [buffer]);  // buffer is detached here,
+                                                   // its memory now in the worker
+```
+
+Two differences are intentional:
+
+- **The transfer list must be an array.** Omitting it, or passing `undefined` or `null`, means "transfer nothing"; every other non-array value is a `TypeError`. The WebIDL iterable-to-sequence conversion that lets `structuredClone` take a `Set` or any iterable lives in the JavaScript wrapper around `structuredClone`; `postMessage` is native all the way down and has no such wrapper.
+- **Host objects degrade instead of throwing.** Posting a native/interop object delivers an empty object to the receiver rather than raising a `DataCloneError`. This is long-standing shipped behavior that predates the V8 port, and app code relies on it; `structuredClone`, being new, follows the spec and rejects. The asymmetry is encoded in exactly one place — the `HostObjectPolicy` enum in `NativeScript/runtime/StructuredSerialization.h` — and unifying the two on rejection is a breaking change that needs the Android runtime to move at the same time.
+
+## Deviations from the specification
+
+- **`DataCloneError` is an `Error`, not a `DOMException`.** This runtime has no `DOMException`, so failures throw an `Error` whose `name` is set to `"DataCloneError"` — the same shape used for native exceptions (see [Error handling](error-handling.md)). Detect failures with `e.name === "DataCloneError"`; `instanceof DOMException` cannot work.
+- **Only `ArrayBuffer` is transferable.** The spec's other transferable types — `MessagePort`, `ImageBitmap`, `ReadableStream` and friends — do not exist here. A non-`ArrayBuffer` in the transfer list is a `DataCloneError`.
+- **Host objects are not cloneable by `structuredClone`.** The spec leaves platform objects to each host; here every native/interop wrapper is rejected with a `DataCloneError`, because a JavaScript copy detached from its native counterpart would be a wrapper around nothing. Worker `postMessage` deliberately differs — see above.
+
+`SharedArrayBuffer` follows the spec: it is shared rather than copied, and it is not transferable (listing one throws a `DataCloneError`).
