- API: GET /paper/reconcile/identity?date&refresh——缺省读 supervisor 15:10/23:27
已存 identity_reconcile 行,无存行现算并落库(与 build/save 同套幂等);
路由置于 /paper/{aid} 前,与既有 reconcile 端点同组
- 前端: Reconcile.vue 顶部新增恒等式卡片(账户级红绿/未归因±/占比vs容忍0.5%/
可展开逐票缺口+实例市值拆分),页面与菜单更名为「对账中心」;
api/paper.ts 补 IdentityReport 类型族
- 测试: 绿线(50/10050=0.497%pass)+存行复用+refresh强制重算(200=1.96%红)+
snapshot_missing 如实标注,12/12 绿

别家卖到目标值/按账户卖出)——正是「账户可卖视图放行18归属4400股」的变体洞。
改动(_instance_order_wrappers):
- otv value>0 无价(市价拿不到且账本无此票无成本可回退)→ 拒单fail-closed,
不再透传bt_otv引擎target语义(宁可少买不可互卖,策略session定夺=拒单语义)
- 负order_value无价 → 拒单,不再透传bt_ov按全账户卖出
- 事故主洞(同窗双卖吃到60s归因间隙)已由191270c即时归因关闭:新增钉死测试
「双卖窗口阻断」——第一笔4400即时归因(on_order_done钩子)→第二笔闸门读

(=台账equity,实时价缺价回退成本)/jq原生total_value直接读;缺属性回退
现金+Σ持仓市值(同语义)
- momentum_timing_ex/small_cap_ex/value_selection_ex 三处轮动定寸
per_value=cash/N→total/N,守卫cash<=0→total<=0
- momentum 尾部卖出+买入抽独立方法 _rotate_positions(纯移动零逻辑变化,
便于回归直接钉死)
- 原JQ语义per_value=stock_value/len本就是总资产口径,cash口径是移植失真;
all_weather/channel_test的cash读取(递增建仓/现金铺余位语义)按移交指示不动
- 清三文件因此孤儿化的_available_cash import
测试:tests/portfolio/test_sizing_total_value.py 5条——helper 2(直读/回退)
+每策略1条「卖出未入账时定寸不缩水」(fake现金旧值+持仓仍显示旧仓→per_value

- runner_live:engine装配后注入on_order_done=_sync_instance_trades闭包;

fix(shadow): 影子市价单成交基准改实时行情——旧按委托保护价记账恒差1.5%,08-24双轨4/6红根因 [vps]
...
根因(代码级实锤): broker._ref_price 优先用下单传入price,而市价单的price是保护性委托上限(策略侧行情×1.015,BrokerBase契明文'可用作保护价/参考价'非期望成交价)→影子每笔买入虚高~1.5%,卖侧对称低~1.5%。08-24证据三连:momentum/small_cap首次真实成交日25票价差紧聚-150bps(-112~-189);卖侧510500同样-1.54%(排除'晚一根bar随行情'解释);级联=虚价吃掉影子现金6k+→002038买第6只差1678元资金不足拒单(shadow_60日志)。排除用户初判的滑点/费率参数不一致(影子账户slippage=0.0费率正常)。回测/实走无此问题(matcher.py按bar开收价,另一套)。
修: _ref_price(security,price,market)——市价单成交基准=price_getter实时行情,行情不可得退回委托价(告警,可用性优先);限价单沿用传入价(触价语义,旧行为);buy/sell补市价转限价封顶(行情超保护上限按上限成交不追高,卖侧对称)。
+5测试(市价买卖按行情/超上限封顶/无行情退委托价/限价语义不变),trader 254绿+api 171绿。

你印象中改过的是6ecdaab#95标的池pool→all(三表单+后端四处),max_pool当时没动。本次三处对齐: PortfolioBacktest表单默认30→0+过时提示(「MVP验证用,默认30」)清理+routes_portfolio Field default=30→0(防API直调口径分裂,#95同款对齐法)。语义同全链:0=不限,策略层>0才截断。build绿+tests/api 165绿。
