+## ADDED Requirements
+
+### Requirement: IoT Card Batch Allocation Range Allocation Hint
+
+The IoT card batch allocation dialog SHALL provide a derived allocation-count hint for ICCID range selection.
+
+The hint MUST appear immediately below the `iccid_start` and `iccid_end` inputs when `selection_type="range"`.
+
+The count MUST be computed with exact integer arithmetic as `iccid_end - iccid_start + 1` so that long ICCID values do not lose precision.
+
+When displayed, the count MUST use decimal thousands separators, for example `1,000`.
+
+#### Scenario: Show allocation count for a valid ICCID range in batch allocation
+
+- **GIVEN** 用户打开“批量分配”对话框
+- **AND** 用户选择 `selection_type="range"`
+- **WHEN** 用户输入有效的 `iccid_start` 和 `iccid_end`，且计算结果为正整数
+- **THEN** 对话框 MUST 显示 `共分配xxx张卡`
+- **AND** `xxx` MUST 等于 `iccid_end - iccid_start + 1`
+- **AND** 当数量大于等于 `1000` 时，`xxx` MUST 使用千分号格式展示
+- **AND** 当任一端点变化时，提示 MUST 立即更新
+
+#### Scenario: Hide allocation count for incomplete or invalid ICCID ranges in batch allocation
+
+- **GIVEN** 用户选择 `selection_type="range"`
+- **WHEN** 任一起止 ICCID 为空、无法按整数计算，或计算结果小于 `1`
+- **THEN** 对话框 MUST NOT 显示误导性的数量提示
+
+### Requirement: IoT Card Batch Recall Range Allocation Hint
+
+The IoT card batch recall dialog SHALL provide a derived allocation-count hint for ICCID range selection.
+
+The hint MUST appear immediately below the `iccid_start` and `iccid_end` inputs when `selection_type="range"`.
+
+The count MUST be computed with exact integer arithmetic as `iccid_end - iccid_start + 1` so that long ICCID values do not lose precision.
+
+When displayed, the count MUST use decimal thousands separators, for example `1,000`.

+#### Scenario: Show allocation count for a valid ICCID range in batch recall

+- **THEN** 对话框 MUST 显示 `共分配xxx张卡`
