Accepts only the listed options. The output path must have an existing parent directory and must not already exist; it is reserved before the check begins. ## Arguments \--source URL and --target URL required; --scope exact|domain|subdomain|path; --json; --out FILE. ## Exit status 0 when a result artifact is produced, including absent and unknown observations; 2 for invalid arguments or a command failure. Inspect observation.state. Read [configuration and file ownership](/reference/local/configuration) before automating this command. Read [local file contracts](/reference/local/artifacts) for artifact fields. Browse the [local command index](/reference/local/index) for related commands. Reference follows the current development CLI and HTTP contracts. Hosted availability depends on the selected environment. See [capability status](/capability-status).
