If d̂' = (f' : d → d') is last then this lets you factor f̂ : R̂(d̂) → c uniquely via some w : d̂ → d̂'. In terms of d/D this looks like f̂ R̂(w) f̂' (R̂(d̂) → c) = (R̂(d̂) → R̂(d̂') → c) and if we expand it in terms of D f̂ = f : R(d) → c w : d → d' R̂(w) = R(w) f̂' = f' : R(d') → c it looks like f R(w) f' (R(d) → c) = (R(d) → R(d') → c).
