Serve lean: txid.body identity, SH join fks, mempool UTXO overlay - #168
Merged
Conversation
Merkle proofs, Esplora /txids, and Electrum id_from_pos only need create identity. TxTable::get decoded every output. Consecutive header_txs use body_txid_range. Co-authored-by: Cursor <cursoragent@cursor.com>
Esplora /txs and WS block-transactions already have create/spender fks from the SH join. Re-probing tx.head per page item was the leftover megakey gap after /utxo. Co-authored-by: Cursor <cursoragent@cursor.com>
scripthash_history_filtered already documented this. Spend height is at least create height, so future creates cannot contribute to the window. Co-authored-by: Cursor <cursoragent@cursor.com>
Esplora tx JSON and RPC gettxout only need the parent output. TxTable::get_full zipped inwit on every prevout. Stored txid comes from txid.body. Co-authored-by: Cursor <cursoragent@cursor.com>
The prevout commit staged an empty workspace lock via git add -A. Co-authored-by: Cursor <cursoragent@cursor.com>
/txs, /tx/*, merkle, outspends, and block tx lists share spawn_join with /utxo. Tip, hash, and fee-estimates stay on the worker. Co-authored-by: Cursor <cursoragent@cursor.com>
v0/v2 share the archived prev_txid cache. getblockstats parent prevouts use create_fk outs, not per-input tx.head. Co-authored-by: Cursor <cursoragent@cursor.com>
Status, merkle, and outspend existence use tx_fk_by_txid. Spend txid is txid.body; vin is the annotated index. Merkleblock is header + txid.body leaves, not reconstruct_archived_block. Co-authored-by: Cursor <cursoragent@cursor.com>
SH listunspent already has the create fk. Coinbase is whether that fk is first in the block's header_txs range — no packed inwit zip. Co-authored-by: Cursor <cursoragent@cursor.com>
Shared helper funds from mempool SH index and drops mempool-spent confirmed coins. Esplora mempool_stats uses the same loops. JSON for NULL-fk rows is unconfirmed with no block_*. Co-authored-by: Cursor <cursoragent@cursor.com>
Header push already ran on TipNotify. Clients that only subscribe to hashes missed confirmed history until a mempool announce. Window the new height, then send full status. Co-authored-by: Cursor <cursoragent@cursor.com>
COMPAT/OPERATOR match txid.body listings, SH join fks on /txs, and Electrum subscribe restatus on confirming tip. Co-authored-by: Cursor <cursoragent@cursor.com>
