The CLI currently creates or truncates the -o destination before parsing. If -no-unset or -no-empty rejects the template, the previous output is destroyed despite no replacement being written. Parse and validate first; open the destination only after success.\n\nValidation: synthetic local CLI checks confirmed unset and empty-variable failures preserve a sentinel output, while a successful synthetic substitution writes the expected result. git diff --check passed; the repository's documented go test passed; go test -vet=off ./... passed. The additional go test ./... run reports existing non-constant format-string vet diagnostics in unchanged main.go lines.
