see what happens to cause it to recover.

this should set you up as a starter: https://www.liquity.org/blog/on-price-stability-of-liquity

I was under the impression that the oracle signal was on chain, from liquidity pools against other stables

that would mean that if even one of those stables dies, LUSD would destabilize too (and there would be no possibility of intervention, since that protocol is completely ossified). that's worse overall.

Maker was not immutable yet

I was talking about Chronicle, the oracle protocol that spun off from Maker.

basically that is never going to happen.

look at Maker's history, what's been promised, and what's been delivered. don't take it for granted that puredai will ever happen.
