Proposition comprehension_eso_mor_eq : comprehension_eso_mor · δ = π fib. Proof. unfold comprehension_eso_mor. rewrite !assoc'. use z_iso_inv_on_right. refine (_ @ !(dependent_sum_map_eq _ _ _)). unfold comprehension_eso_mor_help. use (cancel_z_iso _ _ γΓ). rewrite !assoc'. pose (maponpaths (λ z, z · PullbackPr1 HΓ) (!(dfl_ext_identity_eq left_tm right_tm))) as p. cbn -[left_tm right_tm PullbackPr1] in p. rewrite !assoc' in p. rewrite left_tm_pr1, right_tm_pr1 in p. rewrite !assoc' in p. exact p.
