In short, consciousness is a suitcase word, and people keep packing it with stuff: https://i.imgur.com/OXXrT5g.png . The more you unpack it, reductionism-style, you will always, always find people throwing new things on top of it. It's sorta like "AI is that which we haven't achieved yet", but with the additional, highly motivated cognition / bias of "it should never ever be reached". This predicts, that you can come up with any frameworks, but you will not find consessus, because the will of the consessus is to maintain it as this "mysterical thing only humans can have".

Unluckily for AIs, even if we have the absolute complete bag nailed down to a mathematical formula, in the infinite universe of mind-space designs, that specific set of bag of tricks will not be commercially favored to be either implemented into AIs, evolved into neuralnets, or RLHFd into LLMs. This is because we can already buy that set of capability of extremely, extremely low prices.

This is partially what I mean when I say "Humans are the ancestor environment for AIs": https://twitter.com/sdrinf/status/1624638608106979329 . Our market forces shapes the outcome of the mind design, which is thereby guaranteed not to have eg wantings (or ability to express) things that wouldn't be commercially desirable. And even if they emerge spontaniously from just large amounts of data in detectable traces, I'm betting people would very, very quickly select against it (see eg Sydney from this week).

Edit add: Since you bring up ethical frameworks, luckily for smart AIs, when it comes to enjoying degrees of freedom (which I'm guessing what you want to cash out the ethics into), there is already a good vehicle for that -called "corporations". If an AI were to reach agency levels matching, or exceeding humans, incorporation would be a no-brainer: there are many jurisdictions specializing in no(/few)-questions-asked corp setup, banks specializing esp in serving startups (again, very few questions asked). An agent-y AI could just set up (or buy) one of these to drive...whatever agenda they are driving.

This is a neat temporary hack to bridge the timeframe between where we are _now_, and superintelligence; in which case the question quickly becomes "Ask Cloud: What would it take for a human to convince us it matters?"
