…defined:] Elixir 1.20 deprecates the project-level `xref: [exclude: ...]` option in favor of `elixirc_options: [no_warn_undefined: ...]`, which has been the canonical compiler option since Elixir 1.7. mint requires `~> 1.12`, so the new option is valid across the entire supported range — no version gating needed. Behavior is identical: the same modules/MFAs are excluded from undefined-function warnings. Verified `mix compile --warnings-as-errors` stays clean with castore (optional) absent.
