if you just create

product.v1.3

through lookup (https://wiki.dendron.so/notes/0e57f8d1-e501-49db-974c-01eb64c20c22/), there will only be one file (

product.v1.3.md

). Internally Dendron will recognize

product

and

product.v1

as a hierarchy, but they will be virtual and not saved in the file system (As long as you don't create them yourself later. You can if you have to later down the line). If you intend to publish, the default behavior will be writing the stub notes to file, but that can also be disabled through config.
