kChunkSize is an int32_t and the chunk index is a uint32_t, so `aIndex * kChunkSize` is evaluated in 32 bits and wraps once the index reaches 16384, i.e. for entries larger than 4GB. Both results feed int64_t offsets. CacheFile::BytesFromChunk already casts before multiplying; do the same at the two remaining sites.
