AIcoding 第 5 步 todo 开发（开发计划 v2.0）前半段： - T-1 3 张新表 DDL（core_convert_request 6 态 ENUM / core_trade_calendar / core_share_rule）+ 种子 + sqlite 单一事实源同步 + 列清单断言 - T-2/T-2b calc 扩展（product_round/redeem_amount/partial_qty）+ 真实净值实算回填 - T-3 convert_request_repository（6 态 + 条件 UPDATE 守卫）+ core_ro 三读方法 + share_lot_repository.available_qty_with_inflight（R-3 在途占用推导） - T-4 convert_repository.sync_mirror 成为 risk_convert_detail 唯一进度镜像写入口 （旧三方法标 Deprecated，T-7 后删） - T-5 locks.py 锁键构造器 convert_req_lock_key / convert_confirm_lock_key - T-6 convert_service.accept_convert 受理事务（八步：锁→幂等→校验→受理日顺延 →在途占用校验→落单→镜像+审计→202；不扣份额/不折算/不写流水） + tests/test_convert_accept.py（16 用例） + scripts/dev/verify_convert_accept.py（真库 36/36 一致） + trading_calendar.py 纯函数包（R-5）+ 21 用例 T-6 真库实测暴露并修复：confirm_eta 在日历数据边界抛 ValueError，会让已落库 的受理单在调用方眼里变 500；改为展示性字段容错 + 单测守护。 基线：798 passed / 10 skipped，零回归。
