+# Release metadata, not foundry config: `rainix-autopublish` reads `version` as
+# the next, unpublished Soldeer release and rewrites it when it publishes, and
+# neither forge nor soldeer reads anything here. `[external.*]` is the section
+# foundry reserves for another tool's config and ignores; a section it does not
+# reserve is read as a profile, which it warns about on every invocation and
+# `forge config --fix` rewrites into `[profile.*]`.
