1. Consumer deposits GRT into PaymentsEscrow (keyed by their own address as payer)
2. Consumer includes X-Consumer-Address header on every gateway request
3. Per request: gateway signs a TAP receipt (EIP-712 ECDSA, random nonce, CU-weighted value)
   — consumer address is encoded in receipt metadata so the correct escrow is charged
4. Receipt sent in TAP-Receipt header alongside JSON-RPC request to dispatch-service
5. dispatch-service extracts consumer address from metadata, checks their escrow balance,
   validates signature, persists receipt to PostgreSQL
6. dispatch-service TAP aggregator batches receipts per consumer → sends to /rav/aggregate
7. Gateway returns a signed RAV (Receipt Aggregate Voucher) with payer = consumer address
8. dispatch-service collector submits RAV on-chain every hour: RPCDataService.collect()
                               → GraphTallyCollector (verifies EIP-712, tracks cumulative value)
                               → PaymentsEscrow (draws GRT from consumer's escrow)
                               → GraphPayments (distributes: protocol tax → delegators → provider)
                               → 2% data-service cut retained by RPCDataService (1% burned, 1% as revenue)
                               → remainder lands at paymentsDestination
