(* shared module type for git operations.
   all operations conform to the same signature so dispatch
   in main.ml is uniform. [remotes] declares how many remote
   display lines the operation needs per repo slot.
   exec returns 0 (no display, runs serially with direct stdout). *)

module type Op = sig
  (* number of remote display lines needed per repo slot.
     0 = no display (exec), 1 = origin only (pull/init),
     n = all remotes (fetch/push). the caller passes in the total
     platform count; operations that need fewer just return
     what they need. *)
