Sourdough bread of partial failure

Two major things went wrong with this loaf of bread:

1) I didn't knead it enough before the initial rise
2) I left it in the oven so it would be warm for the second rise. I left the house. Someone turned the oven on without realizing the bread was in the oven.

That second reason is probably the most significant in why I came out with a flat loaf that did not rise at all during baking. I also forgot to slash the top of the loaf before putting it in to bake, but it didn't really matter, as there was no expansion of the dough during baking, anyway.

Its started out well, though.

My starter seems to have recovered from its week without refrigeration without any harm.

It's not a super-dense loaf, so at least it's edible and tasty, but hopefully future attempts will prove to be more successful.
