¶ 1. MDB 刷卡支付流程梳理 / MDB Card Payment Process Overview
¶ 1.1 范围与角色 / Scope and Roles
- 范围 Scope：刷卡 Cashless（地址
10H）
Scope: Cashless payment (address10H). - 角色 Roles：App 为 VMC 下发命令；POLL(
12H) 由 MDB-RS232 透传器完成，App 只收推送帧。
Roles: The App acts as VMC to send commands; POLL (12H) is performed by the MDB-RS232 pass-through device, and the App only receives pushed frames.
¶ 1.2 VMC 下发指令：时机与意义 / VMC Commands: Timing and Meaning

发起扣款；设备态 → ENABLED；引擎 WaitingPayment；60s 超时Initiate deduction; device state → ENABLED; engine WaitingPayment; 60s timeout. |
| 用户取消 / 超时 / 会话取消等 User cancel / timeout / session cancel, etc. |
VEND CANCEL | 13 01 |
撤销进行中的 Vend（10 06 刷卡拒绝时不发）Cancel ongoing Vend (not sent when 10 06 card denied). |
出货成功 finishTransaction(true)Dispense success finishTransaction(true) |
VEND SUCCESS | 13 02 II II |
确认出货，正式结算扣款 Confirm dispensing and formally settle deduction. |

VEND FAILURE | 13 03 |
通知失败/冲正 Notify failure/reversal. |
| 取消、拒绝收尾、成功/失败结算后 After cancel, denial cleanup, success/failure settlement |
SESSION COMPLETE | 13 04 |
结束本会话（期望应答 10 07），随后再发 14 01 开下一轮End this session (expected response 10 07), then send 14 01 again to start next round. |
辅助逻辑：ensureReadyForVend() —— 非 READY 时先 sessionComplete()（脏会话），仍不行则全量 initialize()。
Auxiliary logic: ensureReadyForVend() — when not READY, first call sessionComplete() (dirty session); if still not working, perform full initialize().

引擎行为 Engine Behavior |
|---|---|---|---|

Session Cancel | 设备请求取消 Device requests cancel |
onCashlessDenied → VendCancel + SessionComplete |
10 05 [HH LL] |
Vend Approved | 刷卡批准 Card approved |

SessionComplete 跳过 VendCancel → FailedSessionComplete skips VendCancel → Failed. |

Offline | 链路/设备离线 Link/device offline |
设备 OFFLINE；支付中按失败收尾Device OFFLINE; if paying, finalize as failure. |
未接线的 POLL 码（03 BEGIN SESSION 等）见 [.cursor/rules/mdb-development.mdc](.cursor/rules/mdb-development.mdc)；本项目用 VMC 主动 14 01 + 13 00 替代标准 Begin Session 被动路径。
Unconnected POLL codes (03 BEGIN SESSION, etc.) are described in [.cursor/rules/mdb-development.mdc](.cursor/rules/mdb-development.mdc); this project uses VMC active 14 01 + 13 00 instead of the standard Begin Session passive path.
