+# Hermes pins every one of its ~120 dependencies with == and declares
+# Requires-Python >=3.11,<3.14, so it can neither be built against Arch's
+# Python nor share the python-* packages, and Arch's next Python bump would
+# break any venv this package built. So the package ships a wrapper rather than
+# the application: mise gives Hermes a private, supported environment on first
+# run and keeps it current, the arrangement omarchy-mise-install already makes
+# for the other coding agents. pkgver therefore tracks the wrapper, not Hermes.
