The rug was purchased by me within the last month. There is no visable blooming. There are no stains that I can find. There is no moth damage, or any damage that I can find.
I am new to learning about rugs, so I do not know what you are asking about with exposed warps. However, the back is clean, with no damage.
I should add that I do not know the history or who owned the rug before I did. However old it actually is, it is clear that it could not have been in a high-traffic area.
And, yes, all the corners are in tact (sorry, it is very big, and some of it is covered by furniture in my family room, so it was hard to get a good pic of the entire rug.) The fringe on both ends is also in good condition.
I will comment that the rug seems a little thin? I could be wrong. The only other rugs I have owned were machine made, and thicker. This could be a normal thickness for a handwoven rug, and I would not know.
