+"""``/api/config/payers`` and ``/api/config/payers/{payer_id}/configs`` — payer-config read views.
+
+Both endpoints are read-only configuration surfaces used by the UI's
+"Edit payers" page:
+
+- ``GET /api/config/payers?is_active=...`` lists all configured
+  payers (PayerConfig records) — the set of payers the operator has
+  registered, regardless of whether they have inbound config blocks.
+- ``GET /api/config/payers/{payer_id}/configs`` returns the full
+  list of ``(transaction_type, config_json)`` blocks for a given
+  payer. Each block has a ``source``: ``"yaml"`` for the on-disk
+  ``config/payers.yaml`` default, ``"db"`` for any runtime override
+  recorded via ``/api/admin/reload-config``.
+
+These are configuration surfaces, not claim-processing surfaces.
+They live here (under ``/api/config/``) rather than under
+``/api/payers/`` because the latter is the drill-down rollup
+(see ``api_routers/payers.py``).
+
+SP36 Task 7: this block moved here from ``api.py:3167`` (after
+the SP21 provider-detail helper, before the Auth routers divider).
