UR DBs are SQLite3 DB's, but with .urd suffix, instead of .db / .db3 suffix, and with their special UR signature, i.e. first 15 bytes of the DB being _Ultra Recall DB_ instead of _SQLite format 3_
That is correct.

Quote:
UR is able to open somefile.urd, even with the generic _SQLite format 3_ signature
Also correct. And UR can open UR format files (with either signature) if they have another extension (i.e., .db, .db3) or no extension.

Quote:
but then again, stores this file with its own signature.
Incorrect. UR accepts either signature, and it does not update the signature of an existing file. So after you change a file (once) to the standard SQLite format 3 signature, you can open/edit it in UR and other SQLite tools from there on out.
