YarnSpinner-Unity keys translated lines by line tag and stores a Lock (first 8 characters of the SHA-256 of the base text); when the inspector update runs, changed base lines get '(NEEDS UPDATE)' prefixed to the translation, new lines arrive empty and removed lines are dropped. Editing base text without the update leaves stale translations unflagged.
