* or 5, if this list also has "personhood" in it
No, not really. It has pretty standard definitions in philosophy and science, or it wouldn't have been able to be tested for over several decades. I suggest spending some time reading the wiki, it gives a pretty detailed overview.
The only point you have is about consciousness, and we don't need to understand the entire thing to understand parts of it or observe it, just like gravity.
• The ability to recognise one's own body as distinct from that of others, as demonstrated by plants.
• The ability to pass the mirror test, which some AI pass, but whose relevance is widely debated in animal psychology both on the grounds of sensory chauvinism and because it may cause both false positives and false negatives owing to us not being able to converse with the animals we're testing.
• Introspection, except that now we've got LLMs responding much the same way Turing hoped they would when outlining his eponymous test and suggesting that a "viva voce" interrogation would have us know if the machine was innovative or "learnt it parrot fashion"*.
As humans are also demonstrably great at confabulating reasons for their acts (see: split brain surgery, specifically experimental research on patients' cognitive functioning after surgery), it is unclear whether humans score any differently than LLMs in this test irregardless of if LLMs do or don't count as people in any other sense.
• Qualia: nobody knows.
• Mindfulness, meditation and spirituality: arguably only those who explicitly practice the appropriate mental techniques, e.g. Buddhist monks and similar.
• Public/social awareness of self-standing in community: everyone who is "cringe" fails.
* fun fact: AI critics have been stochastically parroting the stochastic parrot criticism since at least 1949
Like I said, it's actually very well defined because it's been being studied for decades at this point. Just because it can sometimes be an overloaded term in colloquial usage doesn't negate that.
I again suggest you give the wiki page a read. It's quite in-depth and detailed with plenty of good references.
That makes it not well defined.
I did in fact read the Wikipedia page, and also have an A-level in philosophy, which means I've written more about this in three homework esseys than the total length of the English Wikipedia article: https://en.wikipedia.org/wiki/Self-awareness
It's absolutely well defined it's just a complex topic. Most of the examples you gave in your last reply are never defined as self-awareness in an academic paper, e.g. qualia is always separate and the mirror test has always just been an indicator not the thing itself.
