 * **When to use**
 *

 * known, such as after a routing decision or after decoding stored shard-id
 * parts.
 *
 * **Details**
 *
 * Repeated calls with the same `group` and `id` return the same cached
 * `ShardId` instance. The returned value stores those fields, compares by
 * `group` and `id`, formats as `group:id`, and uses that string form for
 * hashing and primary keys.
 *
 * **Gotchas**
 *
 * `make` does not compute a shard from an entity id or check whether the shard
 * belongs to the current sharding configuration. Pass the shard group and
 * numeric id produced by the routing or storage layer.
 *
 * @see {@link toString} for formatting an existing shard id as `group:id`
