Gateway retains authenticated HTTP adaptation and supplies the configured registry. Focused domain, registry-backed gateway and tagged integration validation passed. |

The accepted-but-unapplied filter field is explicitly retained as an unchanged compatibility gap. Focused domain, registry-backed gateway and tagged integration validation passed. |
