Status: IN
SSTable point lookups return correct results through two-phase search (binary search on sparse index to identify block, then linear scan within block), with clean None returns for keys not present in the table.
Two base beliefs about SSTable read-path correctness form a positive claim gated on the caller's responsibility to maintain sorted key order — violation silently corrupts binary search results with no error, since add() performs no sort validation
