Source-of-truth note​

This unit is anchored to Grokking Algorithms and the source chapter "Chapter 5: Hash Tables". Use external resources only to clarify, extend, or modernize details without replacing the chapter's conceptual spine.

External enrichment​

No chapter-specific enrichment resources are curated yet. Add them in the unit manifest when a source clearly improves learning.
