Check YAML syntax first
The tool parses YAML locally and reports syntax errors. Use public or redacted snippets; do not send tokens or subscriptions through correction channels.
Separate syntax, references and runtime
Valid syntax may still have group or provider-reference issues. DNS, TUN, scripts, privileges and live connections are outside a complete-validation claim.
Review before running
Before copying results, check sources, the target client and supported scope. Static results do not establish core loading or connectivity.
Scope and sources
This is general guidance based on upstream documentation, without invented device tests or shared-client UI steps. Consult the original documentation for specific versions.
