Function array_vshard_for_tile

nodedb-cluster/src/distributed_array/routing.rs:33–37

Determine the primary owning vShard for a single tile identified by its raw Hilbert-prefix value. `hilbert_prefix` — the tile's u64 Hilbert key. `prefix_bits` — number of high-order bits used for routing (1–16). Returns the vShard ID in `[0, VSHARD_COUNT)`.
