esplora: UTXO status from SH join (no per-coin tx.head) - #165
Merged
Conversation
The SH join already has txid, vout, value, and height. Per-coin tx.head plus TxTable::get was a second Class A pass on megakey live sets. Unique-height headers fill block_hash/block_time. SH joins run on spawn_blocking like /block. Co-authored-by: Cursor <cursoragent@cursor.com>
History still needs spender txids. Balance and listunspent only need spentness, so megakey joins skip spender txid.body. sh_join logs need=. Co-authored-by: Cursor <cursoragent@cursor.com>
tx_count is unique touching txs. Fks already identify those rows, so /address skips create and spender txid.body on the shared join. Co-authored-by: Cursor <cursoragent@cursor.com>
Operator debug sh_join now includes need=. Identity sidefile IO is optional per surface (history vs listunspent vs balance/stats). Co-authored-by: Cursor <cursoragent@cursor.com>
