@jakebailey Here are the results of running the user tests with tsc comparing main and refs/pull/62730/merge:

There were infrastructure failures potentially unrelated to your change:

1 instance of "Git clone failed"

Otherwise...

Everything looks good!

@Renegade334 Do these differences seem correct to you? I think these are a result of the change you just made.

Renegade334 · 2025-11-11T20:11:40Z

The top800 ones? Those do look correct – these are essentially the exact same ArrayBufferView<ArrayBufferLike>-to-ArrayBufferView<ArrayBuffer> assignability errors that were unearthed in 5.9 in the rest of the library, but an erroneous override on WebSocket#send() shielded the effects from this specific method.
