Incidentally there have been discussions here recently about using "weak" or unfed starter from the fridge, and I just baked some bread like that yesterday.
Ran out of bread, and my plan for a specific bake yesterday was not meant to be (starter was not quite there yet). Didn't even have much of my normal refrigerated rye starter that I would use in a bread without issues. But I had relatively recent discard from the last week or two, a mix of whole rye 100% hydration and white 50% hydration stiff starter. I took all discard I had and some of the relatively fresh starter, mixed with some bread and whole wheat flour, salt, and water. I was roughly weighing ingredients, but I didn't know the exact hydration of the discard, and there was quite a lot of it, so I had to adjust the hydration by adding extra flour after the dough turned out to be way more liquidy than I expected from my rough calculation.
Here is the approximate formula, take the numbers with a grain of salt: https://fgbc.dk/1ab1
At first it appeared that everything was going well, I did some stretch&folds and slap&folds, it seemed to develop some strength. Then I left it to ferment for a few hours with occasional stretch&folds. However in the end the dough was weak and sticky, as if overfermented - although there were barely any signs of fermentation visible. I think the discard brought too much acidity and the gluten never formed properly, or got degraded very quickly. So I just dumped the dough into two small tins (could have put in one, but I was worried it might decide to grow), sprinkled sesame seeds on top and left in the fridge overnight. Didn't notice much growth by morning, but when baked the bread had a nice oven spring, and generally looked good!

It is on the sour side of my typical bread, the crumb is a little moist, but soft. On the picture it looks a little better than it is for most of the loaf, for some reason it's more open close to the end, and a little more closed and dense inside - but it's still actually good throughout. The crumb tears just a little when cutting, like into shreds... A bit like rye bread with not perfect crumb does. But it's a very minor issue, which doesn't really affect the eating experience.
Overall, it's a surprisingly good bread!
Just wanted to share this as an example of baking with unfed starter, it can cause challenges, but bread can also turn out well!

Ilya those look quite good. I guess you ran into acid related challenges which don’t really surprise me depending on how long that starter discard was in the fridge for. When I was checking pH more regularly than I do now, I’d find that my red fife starter after a week would have a pH in the 3.6 range and rye lower around 3.5 or so. So that unfed starter might be at the lowest level around 3.4 and with a really high TTA.
In the end it baked up two nice loaves which is quite impressive.

Thanks Benny - indeed, I think the acid load was too high from the beginning, and after a short fermentation the gluten started degrading. The rye discard had a layer of hooch on top (which I tried to remove), so it sure must have been very sour. Fermentation-wise I am sure the dough would benefit from more time, but gluten would be completely destroyed.
Thought this story wouldn't have a happy ending, but it did! Surprising that you got the oven spring that you did. So, maybe as Benny said the acidity/proteases broke the dough open, but the fermentation still had some way to go? A puzzle, but what a great outcome.
I agree the dough was likely a bit underfermented in the sense of gas production, but I think longer time, especially a longer warm bulk, would completely destroy the gluten. So probably I caught it in the middle ground with sufficient trapped CO2/grown microbial population, and still with a bit of strength.
