+## [1.0.76] - 2026-06-23
+
+### 新功能
+- 商品详情页：双击商品图片即可全屏查看，支持双指缩放、左右翻页
+- 入库单详情新增「确认进价」：先以 0 价（待定）入库的调货单据，价格确定后可补填真实进价，系统自动回填库存成本、已出库成本与对供应商的应付，售价/应收不受影响；库存与入库明细中未定价的商品显示「待定价」
+
+## [1.0.75] - 2026-06-22
+
+### 新功能
+- 出库单列表新增「商品编码」搜索框：输入完整商品编码回车，即可精确查出包含该商品的所有出库单（与原「单号/往来单位」搜索互不影响）
+
+### 变更
+- 移除「系统设置 → 数据管理」里的数据导入入口：数据导入不再对用户开放
+
+## [1.0.74] - 2026-06-22
+
+### 改进
+- 入库单 / 出库单详情页的商品明细表新增「生产日期」「批次号」两列，便于核对货品批次信息

+## [1.0.77] - 2026-06-22
+
+### 新功能
+- 出库单列表支持按「商品编码」精确反查：可查出包含某个商品编码的所有出库单。同时为出库明细新增 (门店, 商品编码) 复合索引，在数万条明细下仍保持毫秒级查询，不影响写入。
+
+## [1.0.76] - 2026-06-22
+
+### 修复
+- 修复「编辑入库单草稿后合计金额变成 0」的问题：此前每次编辑草稿会把单据合计金额错误清零（明细的单价/金额正常，仅单据头合计未重算），现已按明细正确重算。

+  <div class="sub">调货「先卖后定价」场景 · 分支 feature/jiu_20260623 · 2026-06-23</div>
+
+  <div class="lead">
+    从朋友处调货，价格未定时以 <b>进价 0（暂估）</b> 入库并照常审核、出库售卖；价格确定后，对该入库单执行
+    <b>「确认进价」</b>——系统<b>前向补偿</b>真实成本（不反审核、不撤销任何已发生的动作）：回填库存成本、已出库成本快照，
+    并按差额补一条应付流水。售价 / 应收完全不受影响。
+  </div>
+
+  <h2>1. 背景与取舍</h2>
+  <div class="card">
+    <p>老系统做法是「入库价填 0 → 出库 → <b>反审核</b>入库单改价 → 重审」。新系统已审核单据只读、无反审核、流水不可变、库存成本一旦落地无修改接口——强行复刻反审核在「货已出库」时几乎无法回滚干净，且违反现有不可变设计。</p>
+    <p>故改用会计上的「暂估入库 → 实际成本确认」模型：<b>不反审核</b>，以一次前向调整补齐成本与应付。关键前提是新系统的<b>序列号数据模型</b>让这件事变得精确——</p>
+    <ul>
+      <li><b>product ↔ 入库明细 1:1</b>：每行入库新建一个独立 product（序列号），出库明细也带 <code>product_id</code>。因此「某次调货的成本」就是「某个 product 的成本」，可凭 <code>product_id</code> 精确回填到它的所有已出库行，<b>无需额外的批次消耗映射表</b>。</li>
+      <li><b>库存成本天然可空</b>：<code>inventories.unit_price</code> 为 <code>*float64</code>，0 价入库即存 <code>NULL</code>，<b>天然表示「待定价」</b>。</li>
+    </ul>
+    <p>用户确认的口径：①不填预估、直接填 0；②确认后补成本 + 补应付流水；③调货<b>不</b>单独建单据类型，复用普通入库单；④利润统计遇到无进价的行须跳过并单独说明。</p>
+    <p><b>简化决策</b>：不新增 schema 字段（遵循「禁止为每个业务字段改表结构」）。约定 <b>成本待定 = 成本为 0 / <code>unit_price</code> 为 NULL</b>。调货白酒成本不会真为 0，歧义可忽略。</p>
+  </div>
+
+  <h2>2. 核心动作：确认进价</h2>
+  <div class="card">
+    <p>接口：<code>POST /api/v1/stock-in/orders/:id/confirm-cost</code>，body <code>{"items":[{"item_id":N,"unit_price":50.0}]}</code>。
+    仅 <b>approved</b> 单可确认（draft 直接编辑即可）；权限 <b>管理员/超管</b>；后端实现 <code>StockService.ConfirmStockInCost</code>。</p>
+    <p>一个事务内，对每个有变化的明细（旧价→新价，差额 <code>diff = (new-old)×qty</code>）前向写补偿：</p>
+    <div class="flow">
+1. <span class="c">入库明细</span>   StockInItem.unit_price / total_price 改为真实值
+2. <span class="c">剩余库存</span>   Inventory.unit_price  NULL → 真实值  (按 stock_in_item_id；已全出则无行)
+3. <span class="c">已出库行</span>   StockOutItem.unit_price / total_price 回填  (按 product_id；不动 sale_price)
+4. <span class="c">入库单总额</span>  StockInOrder.total_amount += Σ diff
+5. <span class="c">应付差额</span>   新增 FinanceRecord{type:payable, amount:Σdiff, ref_type:stock_in_cost_adjust}
+6. <span class="c">参考进价</span>   Product.purchase_price 同步（按 product_id）
+    </div>
+    <p><b>幂等 / 可重复</b>：以「旧价→新价」差额计算，多次修正各补一条差额流水（如 0→50 补 +500，再 50→60 补 +100）。</p>
+    <p><b>应付余额语义</b>：<code>balance</code> 是该往来单位「应收 + 应付」混合的滚动总账（沿用既有 <code>partnerLastBalance</code>），确认流水在此基础上累加差额。</p>
