you shouldn't need to link WTF.  Link JavaScriptCore instead.

nope

the bitwise and assumes 64-bit size_t, and it's not necessary.

This truncates 256-65535.  not great.

It didn't, because we're only encoding 8-bit strings.

But I made that more explicit.

This looks like an unneeded Vector copy.  Can we just pass a Vector&& and avoid this wrapper too?

static_cast

unnecessary cast

nit: I think "[" can be '['

> +            resultMessages.append(WebKit::WebPushMessage { Vector<uint8_t> { reinterpret_cast<const uint8_t*>(data.data()), data.length() }, message.registrationURL });

nit: I wonder if you could use a Span instead of a Vector here because all you are doing is sending it.

line break is probably a typo

webpushtool didn't have any dependencies so it was building out of order with WebKit.framework itself.

That's why incremental builds worked, but not clean builds.
