Fix Development Behavior

The Fix Development Behavior Tree is shown below.

(A) Fix development is relegated to the Vendor role, so Non-Vendors just return Success since they have nothing further to do.

(B) For Vendors, if a fix is ready (i.e., the case is in $q^{c s} \in V F \cdot \cdot \cdot \cdot$ ), the tree returns Success.

(C) Otherwise, engaged Vendors ( $q^{r m} \in A$ ) can

create fixes
set $q^{c s} \in V f d \cdot \cdot \cdot \overset{F}{\to} V F d \cdot \cdot \cdot$
emit $C F$ upon completion
