Relay bootstrap treated endpoint availability as activation, bypassing the platform configuration's explicit opt-out. An injected relay URL could provision credentials from a native-only profile and suppress its native connectors even when relay was disabled. Reuse the gateway's platform merge and boolean normalization for the explicit-disable decision. Guard registration overrides, discovery, media, and all dial/retry entrypoints; preserve URL-only legacy activation and explicit operator enrollment. Skip relay-exclusive native suppression for an opted-out relay. Add real-config startup and standalone regression coverage, including inherited credentials, managed config, config precedence, native delivery, and fresh-token retry. Document restart semantics without claiming live socket teardown.
