Inside .... water leaking in from the roof was splattering on the wall as it hit the floor. One of the images shows where I cut the rotted purlin out and scabbed a 2x4 back in. I will find out next time it rains if it's fixed or not for sure.

How's the flooring and siding there, squishy or just stained?
Everything else looks great....looks a lot like my shed floor.
