+# Google claim and identity mapping
+
+The broker uses the upstream OIDC `sub` as the stable federated identity key.
+Email is a mutable profile attribute and is never the external identity key.
+
+The default mapping policy is:
+
+| Upstream claim | Keycloak target |
+|---|---|
+| `sub` | stable username `${ALIAS}.${CLAIM.sub}` and federated identity ID |
+| `email` | email |
+| `given_name` | first name |
+| `family_name` | last name |
+| `picture` | custom `picture` attribute |
+| `hd` | custom `hd` attribute |
+
+The Identity Provider uses `syncMode=IMPORT`: profile values are imported on
+first login and later local edits are not overwritten on every login. `FORCE`
+is an explicit alternative when upstream freshness is more important.
+
+`./scripts/verify-google-claim-mapping.sh` signs in through the controllable
+OIDC realm and verifies the resulting Keycloak user, custom attributes, stable
+subject-derived username, and federated identity record.
