Will create a new bug to address this since this is not fixing memory safety.

Mason: I'd like to rely on you to make the call. I worry the performance implication of the change in the hot code path. Should we request measurements?

Yeah, I'm definitely concerned about the same thing. This adds a ton of `CHECK` calls that likely slow down the parser significantly.
I'll try to kick some off.

Hi Aditi,
Looking at the code, it doesn't compile for multiple reasons, including `-WUnsafe-buffer-usage`. In the future, could you please:
- Compile the code locally.
- Press the Commit-queue: +1 button and wait for the commit queue results before requesting a code review.
About this patch, I don't think it would be trivial to use AI to fix the UNSAFE_TODO here. Mostly likely, they will be replaced by `UNSAFE_BUFFERS` and a comment explaining why this is safe.
BTW, this isn't the original [AI patch](https://chromium-review.googlesource.com/c/chromium/src/+/7090591) that was proposed for the rotation.
