      # v0.9.0 (Nov 2025) was an intentional, permanent fork of this
      # provider to a fully-regenerated schema mapping 1:1 to libvirt's own
      # XML — the maintainer kept 0.8.x alive in parallel specifically for
      # existing configs like this one, rather than it being a transitional
      # version to move past. `~> 0.8` (>= 0.8.0, < 0.9.0) stays on that
      # legacy line on purpose; every resource block in main.tf uses that

      # see docs/04-tofu.md's "Where this track actually stands").
