Week 1 Cold Revisit

No cold revisit this week. Week 1 is the first week, so there is nothing prior to revisit.

Use Friday to:

• Finish and polish your Pattern Card at .tutor/pattern-cards/arrays-and-hashing.md, including the war-story field.
• Confirm every practice problem’s commit message contains a complete five-question debrief.
• Re-read your Two Sum reflection and make sure you can explain the one-pass map from memory.

The cold-revisit machinery begins in Week 2, which pulls Two Sum and Valid Anagram back for a blind re-solve.
