Sakuma's conjecture for 2-generated axial algebras of Monster type

Let $A$ be a $2$-generated axial algebra of Monster type over a field of characteristic $0$. Sakuma's conjecture. The algebra $A$ is one of the nine Norton–Sakuma algebras. A classification of the $2$-generated algebras is known when a Frobenius form is assumed, and a proof without that assumption was announced by Franchi, Mainardis and Shpectorov in 2018.
