Detailed Description

The sharding_indexed codec, modeled as a Store adapter rather than a codec: a shard is simply the outer chunk's stored object, and ShardStore maps inner-chunk keys onto byte ranges of it via the trailing (or leading) index. The array machinery above stays completely unaware, and nested sharding falls out as ShardStore-wrapping-ShardStore.
