# Channel BI Copy and Data Coverage

## Metadata

- Date: 2026-07-31
- Status: Implemented
- Scope: Desktop Channel BI and H5 BI presentation plus additive analytics range fields
- Confidence: Fact
- Source: channel analytics contracts/provider, desktop and H5 static assets, focused tests
- Last verified: 2026-07-31

## User-Facing Outcome

- The BI-only CHANNEL PERFORMANCE eyebrow is removed from desktop and H5.
- The BI heading no longer shows the updated-through database snapshot copy.
- Visible BI TOTAL PRICE labels are removed; the revenue helper now reads 销售金额合计.
- 各公司本月销售情况 now has a small 数据范围：开始日期 – 结束日期 line immediately below its title on both surfaces.

## Data Contract

- The analytics endpoint continues to read current Finance facts in one repeatable-read, read-only snapshot.
- The response now adds min_arrival_date; the existing max_arrival_date remains the end of the coverage range.
- Both dates come from current daily-version business dates, which are validated to equal the included ARRIVAL dates. The
  browser formats those API values by the active locale and never infers a full calendar month from the browser clock.

## Verification

- Desktop and H5 JavaScript syntax checks passed.
- Focused analytics/Web/UI tests passed, including the desktop/H5 copy contracts and min/max date API assertions.
- No Finance facts, monthly publication artifacts or report-generation behavior changed.

## Design Boundary

This is a preserve-mode refinement using the existing neutral/blue visual system. The range is intentionally a quiet
metadata line under the chart title so it clarifies the partial-month snapshot without competing with the sales ranking.
