Misconception bank
Each row below is a plausible wrong answer, the thinking that produces it, and the remedy that corrects the misconception. These are the foundation of the multiple-choice framing and the targeted feedback a student receives after answering.
Lock / locked file
Misconception. No such concept in ls -l.
Remedy. Remind: Linux doesn't mark "locked" files via ls -l.
Log file
Misconception. Extension-based thinking; ls -l type char is kernel-level, not filename-based.
Remedy. Reteach: the char is about inode type, not filename meaning.
