1. Definition and Overview

The .inx file contains a tightly packed, fixed-width contiguous sequence of 64-bit unsigned integers (pack("Q*", @ids) / pack("a8*", @ids)). It allows $O(1)$ count lookups via file length arithmetic (-s $file / 8) and instantaneous paginated slice reading via binary file seek offsets.
