The proposed Ext-algebra presentation for logarithmic model modules

Fix $s$ with $1\,{\leqslant}\, s\,{\leqslant}\, p-1$. Let $\mathrm{Ext}^\bullet_s$ be the associative Yoneda algebra formed from the extension spaces between the specified irreducible modules, and let $x^{\pm}_{r,i}$, with $i\in\{0,1\}$ and $r\,{\geqslant}\, 1$, be the chosen generators. Ext-algebra presentation conjecture. The algebra $\mathrm{Ext}^\bullet_s$ is generated by $x^{\pm}_{r,i}$ with defining relations

$$x^+_{r,i}x^+_{r',j}=x^-_{r,i}x^-_{r',j}=x^-_{1,1}x^+_{1,0}=0,$$ $$x^+_{r,0}x^-_{r,1}+x^+_{r+1,1}x^-_{r,0}=0,\qquad x^-_{r,0}x^+_{r+1,1}+x^-_{r+1,1}x^+_{r+1,0}=0.$$

Here $i,j\in\{0,1\}$ and $r,r'\,{\geqslant}\, 1$. This is presented as a proposed algebraic structure for the extension algebra, and the supplied text gives no evidence of resolution.
