If the Fukaya category is defined over $\mathbb{Z}$, we can require all holonomy factors to be integer valued. The positivity condition requires all the contributions to $\partial\mathcal{C}=L-L^{\prime}$ to have the same orientation sign. This has the amusing consequence that all holonomy factors associated with $(n-1)$-dimensional moduli spaces contributing to $\mathcal{C}$, must in fact all be $+1$. Intuitively, this means there is a unique such holomorphic curve through any generic point of $L$, and the boundary evaluation of universal family to $L$ is transverse.
