The index maps `block_next_txnum || txid[:8]` (12 bytes) -> `32 byte tweak`. After compaction, `sptweak` column family takes ~8.3GB @ Apr 2026. It allows efficiently: - reading per-block tweaks (blockhash → `block_next_txnum`). - looking up per-transaction tweak (given its blockhash). Also added a test vector for [signet block 200000](https://mempool.space/signet/block/0000007d60f5ffc47975418ac8331c0ea52cf551730ef7ead7ff9082a536f13c).
