CLI

@vidro/cli exposes a vidro binary. These commands are recognized:

Command	Intended role	Current behavior
`init`	Detect a repository and scaffold `.vidro/`	Not implemented. Exits 1.
`generate`	Compile Vidro source into environment outputs	Not implemented. Exits 1.
`validate`	Validate source, references, and resolved configuration	Not implemented. Exits 1.
`check`	Detect drift between source and managed outputs	Not implemented. Exits 1.
`show`	Show resolved configuration with external values masked	Not implemented. Exits 1.

Unknown commands also exit 1, after printing the command list. --help prints the same list and exits 0.

vidro show is specified to mask external values. That masking is not implemented. There is no published npm package, so npx vidro is not an install path yet.
