An interactive concept flow for hash tables: from keys to buckets, from its assumptions through the main operation and boundary checks.
trace / request.md
readyA hash table transforms a key into a hash value and uses part of that value to select a bucket or slot. The table then checks key equality because hashes can collide: equal hashes do not prove equal keys. Correctness therefore depends on both a stable hash/equality contract and collision handling.
Use the stages in order to explain hash tables: from keys to buckets. Each stage makes one assumption visible: what the operation promises, what representation it uses, how state changes, which boundary can invalidate a shortcut, and what evidence confirms the result.
For a worked explanation, continue to the topic article and execution trace.
