Mercury rules no nakshatra inside Libra, so it can only act here as a sub-lord (or as the sign-level dispositor).
The narrowest Mercury sub-lord slice in Libra is 1.89° wide, about 8 minutes of Ascendant motion; the widest is 1.89° (≈8 min). The Ascendant moves roughly 1° per 4 minutes on average, so a few minutes of birth-time error can change the sub-lord.
