+# Allow the agents AppRole to seed the ghp secrets engine's admin credentials.

+# token from admin_token at ghp/config creation time; that key is currently
+# unseeded, so the master apply aborts on the ghp data-source read. This grants
+# the agents AppRole scoped write here so an agent can seed the value. Deployer
+# read is already granted via policies/kv/service/vault/secret_backends_read.yaml,
+# so this only adds the write side for the agents identity.
