Till — Ishum + Parker + master file + Luke

Best-practice combo. Human coffee quotes EUR. Settlement that exists is native KAS. The meter for machine calls is STP-KAS/kaspa-x402. Do not weld the names.

Public one-liner: self-hosted Kaspa till; quotes EUR/USD; settles native KAS; not x402.

Original running till: http://127.0.0.1:8090/pos · source STP-KAS/ishum

Parker: skip centralised stablecoins for dapps. Master file: dollars 0–0. Luke: bind kaspa-x402 for a call. Sutton: related sub-series of this invoice, not a global mutex.

Original POS

Desk-local only. The iframe talks to 127.0.0.1:8090 on the machine that runs Ishum. On the public site it will be blank. Three rails can appear on checkout. kUSD/USDT default on if none selected. Blue-score delta. Paste-txid can claim any inbound payment.

Best practice	Original :8090	New tab
Not x402 / no `PAYMENT-*`	…	pass
Quote fiat, settle native KAS	…	pass
kUSD / USDT default off (Parker + master file dollars 0–0)	fail — Init turns all three rails on	pass — rails not on the keypad
No claim-any-payment (payload mandatory)	fail — paste-txid can claim any inbound	pass — URI `message=invoice-id` required
Selected-chain conf, 10 BPS, not ~10s leftover	fail — blue-score delta; README ~10s	pass — 10 selected-chain; 10 BPS ≈ 1s of blocks, not finality
Never holds keys	pass	pass
Luke envelope for machine calls, not this till	mixed — till sits next to 402 naming	pass — explicit split
