Video transcript
The narration of the video, cue by cue.
- Start from the exact checkpoint.
- Name the branch, index and working version.
- Prepare only the isolated course copy.
- Save the complete review document.
- Record the fictional teammate identity explicitly.
- File history follows the selected path.
- Inspect metadata without checking out the commit.
- Read the added line's actual attribution.
- Check Leo's footer separately.
- View options can change attribution questions.
- Return without changing the branch.
- Blame answers what?
- Attribution is a history query, not a social judgment.
- Which distinctions matter?
- Metadata and the queried version determine the displayed evidence.
- Select old file revision: HEAD?
- Inspection selects a view, not checkout.
- Change query to ignore whitespace: bytes?
- The option changes attribution calculation, not stored content.
- Different blame result: first check?
- Different query inputs can legitimately yield different attribution.
- What proves the outcome?
- Check line evidence and independent repository state.
- Verify the actual result, not just a message.
- Predict the changed input before acting.
- Preserve useful work before recovery.
- Prove the checkpoint before continuing.
- Keep the verified result for the next step.
