## Frequently asked questions

### Should secrets be converted?

Use placeholders or references during review; inject real values only from the approved secret manager.

### Which file wins conflicts?

The tool cannot infer deployment precedence, so document the source of truth and layer order first.

### Why validate after conversion?

Conversion can change scalar types, quoting, duplicate-key behavior, or nesting.
