Five legs in tests/lo-password.test.ts, driven through the repo's first UNO helper because --convert-to cannot pass a password; self-skips without soffice or python3-uno and runs with npm run test:lo. The probed format details live in docs/architecture/encryption.md.

"""Open (and optionally re-save) a document through LibreOffice with a password.
|
|
|
|
`soffice --convert-to` cannot pass one, so this drives LibreOffice over UNO instead.
|
|
Prints the document's text on success and exits nonzero when the file will not open.
