Node passes write and end callbacks an error argument (null on success),
but the native callbacks receive none, so an inline callback that names
the parameter read undefined. It now refuses where it is written. The
stream-shims npm case compiles now that stream subclasses are values;
its remaining scenarios are deferred refusals, so it is recorded as one.

On 64-bit targets, an instance of a class in a program-rooted hierarchy
has no vtable word. The rc word holds the class id (the class's preorder
number + 1) in its high 32 bits and the reference count in its low 32
bits. Retain and release update the count as an i32 at offset 0;
instanceof and the other preorder tests read the id at offset 4; virtual
calls and the last release through a base-typed reference index the
hierarchy's constant vtable array by the id. The runtime reads every
object's count through SCR_RC_COUNT.
Runtime-rooted hierarchies (Error, EventEmitter, EventTarget, Event and
the streams), standalone classes and 32-bit targets keep the vtable word.
Both hierarchies construct the base and the subclass, so the base-typed
call sites are closed sets now: they still load the vtable slot, then
call each implementation directly behind a slot test.
Virtual slots whose implementations all borrow a parameter now store the
borrowing body (`@sc_bf_...`), or a virtual adapter, instead of the owned
entry (`@sc_f_...`). Three inheritance codegen tests still required the
owned entry. They now accept either entry for the same implementation,
so they keep checking which method fills each slot.

- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
- Remove C emission, debugging options, and automatic backend fallback.
- Complete LLVM lowering and native bootstrap coverage across supported targets.
- Link executables and libraries with precompiled C runtime packs, including iOS and Android.
- the uncollected-class capture box no longer carries the boxNewC marker comment: run()'s sweep sanitizes the slot before emission, so the pin asserts no R adapters, no uncollected marker, and a plain-kind box
