Four papercuts met while using the CLI: the test menu returned a verdict nobody could find at the end of the output, the file browser never closed once a file was picked, a wrong KeePass password killed the whole CLI, and a configuration key had drifted from the code that reads it. --- FR --- Quatre irritants rencontrés à l'usage : le menu Test rendait un verdict introuvable en fin de sortie, le navigateur de fichiers ne se fermait jamais une fois le fichier choisi, un mauvais mot de passe KeePass tuait tout le CLI, et une clé de configuration avait dérivé du code qui la lit.
