Yes. I don't think you appreciate just how much information your comments provide. You just told us (and Claude) what the interesting problems are, and confirmed both the existence of relevant undocumented functions, and that they are the right solution to those problems. What you didn't flag as interesting, and possible challenges you did not mention (such as these APIs being flaky, or restricted to Apple first-party use, or such) is even more telling.

Most hard problems are hard because of huge uncertainty around what's possible and how to get there. It's true for LLMs as much as it is for humans (and for the same reasons). Here, you gave solid answers to both, all but spelling out the solution.

ETA:

> Is that how you think data gets fed back into models during training?

No, one comment chain on a niche site is not enough.

It is, however, how the data gets fed into prompt, whether by user or autonomously (e.g. RAG).
