 Run the app commands from the Nextcloud stack root, not from the host PHP environment.
 
-Export the current Profile Fields catalog and stored values:
-
-```bash
-docker compose exec -u www-data -w /var/www/html nextcloud \
-	php occ profile_fields:data:export \
-	--output=/tmp/profile_fields-export.json

-Validate an import payload without writing anything:
-
-```bash
-docker compose exec -u www-data -w /var/www/html nextcloud \
-	php occ profile_fields:data:import \
-	--input=/tmp/profile_fields-export.json \
-	--dry-run

+| Command | Description |
+| --- | --- |
+| `occ profile_fields:data:export --output=/tmp/profile_fields-export.json` | Export the current Profile Fields catalog and stored values. |
+| `occ profile_fields:data:import --input=/tmp/profile_fields-export.json --dry-run` | Validate an import payload without writing anything. |
+| `occ profile_fields:data:import --input=/tmp/profile_fields-export.json` | Apply the non-destructive `upsert` import. |
+| `occ profile_fields:data:clear --definitions --force` | Clear app definitions explicitly before reimporting into the same environment. |
 
 Notes:
 
 - The import contract is versioned with `schema_version` and reconciles definitions by `field_key` and values by `field_key + user_uid`.
 - The first delivery is non-destructive: missing items in the payload do not delete existing definitions or values.
 - Validation is all-or-nothing. If the payload contains an incompatible definition or a missing destination user, no database write is performed.
-- For a restore in the same environment, clear app data explicitly before reimporting:
-
-```bash
-docker compose exec -u www-data -w /var/www/html nextcloud \
-	php occ profile_fields:data:clear \
-	--definitions \
-	--force
-```
+- For a restore in the same environment, clear app data explicitly before reimporting.
