Just pointing out a curiosity that doesn’t seem to be documented anywhere. In the Lhasa (zhol) Kangyur, vol. 29, is the Prajñāpāramitā in 8,000 Lines (brgyad stong pa), which ends on folio 522.b (p.1044), with a long colophon similar to those in other Kangyurs on folios 522.b to 523.b (1044-1046). The sūtra is then followed in this volume by more than a hundred pages of assorted texts some of which seem to be by Tsongkhapa but are not listed in either BDRC's outline or rKTs’s handlist.
