From 025ab3487dd0eae165ba5c7c6b389bdb132c999f Mon Sep 17 00:00:00 2001 From: thePR0M3TH3AN <53631862+PR0M3TH3AN@users.noreply.github.com> Date: Sat, 4 Jul 2026 23:35:51 -0400 Subject: [PATCH] zaps: count bitvid tallies in the zap-totals store (#47) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second slice of docs/zap-tally-plan.md §4. runBatch now queries kinds [9735, ZAP_TALLY_KIND] in one call and folds both sources: - 9735 receipts: unchanged sum, but now also records each receipt's payment_hash (from its bolt11) for cross-source dedup. - bitvid tallies: verifyBitvidZapTally (preimage + description-hash bound), amount from the bolt11, pointers from the embedded zap request; counted once per payment_hash so a payment that yields BOTH a 9735 and a tally is never double-counted. Entries gain a paymentHashes set. Counting is gated by isTallyEnabled (singleton reads FEATURE_ZAP_TALLY live). The existing "relay wins" prune clears the optimistic/ledger overlay once a real tally or receipt lands, so the sender's own published tally reconciles the instant bump with no extra plumbing. Tests: cross-source/same-payment dedup, invalid-tally rejection, flag gating (tests/zap-totals.test.mjs). Lint + build green.
