 # Changelog
 
+## 2026-05-09 - 13.27.0 - feat(api-token-manager)
+seed and rotate the environment-managed admin API token during initialization
+
+- Add initialization support for DCROUTER_ADMIN_API_TOKEN with validation, persistence, and admin policy assignment
+- Ensure the environment-managed token is updated when the configured raw token changes
+- Refactor token hashing into a shared helper and add coverage for seeding, validation, redaction, and rotation behavior
+
 ## 2026-05-09 - 13.26.0 - feat(gateway-clients)
 add policy-based gateway client tokens and gateway client route and DNS management endpoints
