defmodule Graft.Link.Off.Plan.Restoration do
  @moduledoc """
  One literal restoration recorded in a `Graft.Link.Off.Plan`.

  Restoration is always *literal* — `replacement` (the path-link tuple
  currently in the consumer's `mix.exs`) is replaced byte-for-byte by
  `preimage` (the original Hex/Git tuple). No AST, no inverse rewrite.
