Additional Review Drills

Use these drills when the primary task is complete and the learner needs another pass over operational reasoning. They are intentionally evidence-oriented and can be answered in a local lab repository.

Drill 01: working tree

  • State which Git state or reference is affected by working tree.
  • Name one command that produces evidence and one field or line in the output that matters.
  • Explain what can be concluded from that evidence and what cannot be concluded from it.
  • Describe the safest recovery path for a shared training repository.

Drill 02: index

  • State which Git state or reference is affected by index.
