As someone who's been in vaguely comparable situations a # of times, but much shorter & less extreme, I've learned this distinction:

Autonomy = bring supplies, and go without outside help for X (but limited) amount of time.

Self-sufficiency = provide for one's own needs, without outside help. Potentially indefinite.

Note that one can be self-sufficient for some (like water), while not for other things (like food or fuel).

Yes, this distinction is somewhat fuzzy. But it's pretty clear where this woman's adventure fits in.

That said: impressive feat!

This was the conclusion I reached after reading how it all developed back in the day. There was no independent monitoring/verification during the time this woman was supposedly in the cave, and it was confirmed afterwards by her own team that she went outside for for eight days "so technicians could repair a router". She also had a computer "without a clock", and was in great shape, did not even need sunglasses after all those days in a cave.

Here is a source in Spanish with some photos of her just after getting out of the cave: https://www.elmundo.es/deportes/mas-deporte/2023/04/15/64398...
