"""Fleet-wide config migration (#91277 Phase 2 — #20438/#54926/#79048 class).
`hermes update` migrated only the active profile's config.yaml; sibling
profiles silently drifted config versions until their gateway hit a config
the new code couldn't read. `_migrate_sibling_profile_configs()` runs the
same non-interactive safe migration for every sibling home, scoped via the
context-local HERMES_HOME override.
These tests use REAL config files on disk and the REAL migration pipeline —
only the profile-root location is pointed at tmp_path.
