Research direction
The issue provides a Lean code example covering quotation prechecking, an unknown identifier, and disabling quotPrecheck, but it names no repository file or test. First inspect the project’s existing example structure and place this behavior in the appropriate documentation section; done means the example clearly demonstrates both the default check and the option that disables it.
