An out-of-tree ProviderProfile with auth_type oauth_device_code/oauth_external loaded and inferred
but was invisible to hermes auth: _register_plugin_provider skipped every auth_type except
external_process and api_key, so resolve_provider() said "Unknown provider", `hermes auth add`
had nothing to dispatch to, the pool could not refresh its rows (REFRESHABLE_OAUTH_PROVIDERS is a
name set) and PooledCredential.from_dict dropped every extra key outside _EXTRA_KEYS on reload.
- hermes_cli/auth_plugin_providers.py (new sibling; auth.py is at the size cap): the registry
mirror now registers every profile under the auth_type it declares, re-syncs after discovery /
on a miss (salvaged from #101768), and owns the seam lookups: auth_handler dispatch, the
fail-loud error for a non-api-key profile that ships no handler, and refresh eligibility
derived from the profile's refresh_credential hook (never a name set).
- providers/base.py: ProviderProfile.auth_handler(action, args) (salvaged from #111610, sync only)
and refresh_credential(entry) -> rotated fields. A separate hook rather than
auth_handler("refresh", ...) because the pool holds a credential row, not an argparse namespace,
and needs tokens back rather than a bool.
- hermes_cli/auth_commands.py: add/status/logout/refresh (incl. interactive add) consult the
plugin handler before the built-in path; `auth refresh` admits plugin rows via the predicate.
- agent/credential_pool.py: _refresh_entry_impl calls the profile hook; from_dict keeps every
non-field key in extra so plugin metadata survives load -> save -> load (to_dict already wrote
it all; sanitize_borrowed_credential_payload semantics unchanged).
- hermes_cli/auth.py: config import moved below PROVIDER_REGISTRY (salvaged from #94231) so a
plugin imported during discovery never sees a partial auth module.
Built-in providers are untouched: only custom/openrouter were unregistered profiles before and
both stay in the skip list; anthropic/nous/openai-codex auth add/status/refresh output is
byte-identical in the before/after probe.
