• Do Tier 1–2 sources confirm that Ibn al-Banna's Talkhīṣ contains lattice multiplication, and that the 12th-c. Lilavati-commentary 'Kapat-sandhi' is the same method?

• The most detailed modern study of Ibn al-Banna's Talkhīṣ commentarial tradition never mentions lattice, gelosia, or shabakh multiplication

• The earliest published manuscript evidence for gelosia-grid multiplication in the Ibn al-Banna tradition belongs to Ibn Ghāzī's 15th/16th-century commentary, not Ibn al-Banna's own 13th-century Talkhīṣ
