写 6 个核心概念到 prop-acc/concepts/prepaid/: - prepaid-account-vs-transaction:账户+流水双对象,与 deposit 同构但多两条独有约束(一户一账、零余额不自动关账) - account-state-machine:Active / Frozen / Closed,canOperate 统一守护,与 deposit 差异(零余额行为、无 ForceClose) - one-account-per-resident:unique(community_id, profile_id) + 跨社区防御(prepaid 独有) - transaction-types:4 种流水(deposit / consume / refund / adjustment),consume 是最高频 - consume-via-bill-collection-type:Consume 走 CollectionType=Bill 而非 Prepaid 的独特设计,资金来源标 meta.fund_source - auto-deduction-design:月初批量自动抵扣 scheduled job 的设计意图(代码待补,issue.md Q4 已记录) 新建子模块知识地图: - prop-acc/maps/prepaid-knowledge-map.md:6 概念入口 + 16 场景预占清单 + 跨域引用 + 代码索引 更新导航: - prop-acc/maps/knowledge-map.md:域总图 prepaid 行链 prepaid 知识地图,状态 🟡 - prop-acc/index.md:同步 下一轮:16 个场景文档(prepaid/scenarios/),按本知识地图骨架填充。 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
