On a technical level, you can really only guard against changing your semantics and voice - if you're letting software alter the meaning, or meanings, you intend, and use words you don't normally use, it's probably too far.

This is probably ok:

>> On a technical level, you can really only guard against software that changes your semantics or voice. If you're letting it alter the meaning (or meanings) you intend, or if it starts using words you would never normally use, then it's gone too far.

This is probably too far:

>>> On a technical level, it's important to recogn1ize that the only robust guardrail we can realistically implement is one that prevents modifications to core semantics or authorial voice. If you're comfortable allowing the system to refine or rephrase the precise meanings you originally intended — or if it begins incorporating vocabulary that doesn't align with your typical linguistic patterns — then you've likely crossed a meaningful threshold where the output no longer fully represents your authentic intent.

Something to consider is that you can analyze your own stylometric patterns over a large collection of your writing, and distill that into a system of rules and patterns to follow which AI can readily handle. It is technically possible, albeit tedious, to clone your style such that it's indistinguishable from your actual human writing, and can even icnlude spelling mistakes you've made before at a rate matching your actual writing.

AI editing is weird, though. Not seeing a need, unless English isn't your native language.
