Overview

The upstream sqids gem derives its max encodable number from 0.size (the machine word size). On 32-bit platforms (e.g. arm32) that yields 2**30 - 1 = 1073741823, which is too small for the 32-bit integer chunks used to encode UUIDs and breaks encoding on machines like the Raspberry Pi 2. max_value only acts as an upper-bound guard in Sqids#encode; it does not affect the encoding/decoding algorithm, so pinning it to a fixed constant is safe and produces identical IDs on every platform.
