Metadata

Date: 2026-07-31
Scope: arr_web/static/index.html, arr_web/static/styles.css, tests/test_arr_web.py
Change type: UI layout and explanatory affordance only
Business-data mutation: none

The fixed generation scope is rendered beside 公司渠道明细 as 固定生成：LianTai、QBD、DY-AI-Easy-KB、FengRun、HanaTour in a muted, small helper style.
The duplicate 固定生成公司 block under 生成报表 is removed; only the 报表月份 input remains in that generator control row.
报表月份 is intentionally retained. The client uses it to calculate each C/O period and release state, query company history for the selected month, and submit report_month with a generation request.
刷新任务 is intentionally retained. It rechecks health and reloads the current Excel source, review draft and company-generation history, then shows a toast; it does not start a report. Its title documents this read-only scope.
The month input has a non-intrusive title explaining that it selects the C/O report month and filters the generation records below.
The Excel upload rail is min(100%, 760px) on desktop with the 104px 提取并核对 action column; at the mobile breakpoint it becomes full-width and one column.

JavaScript syntax and HTML parser checks passed.
Focused suite: 28 tests, OK (tests.test_arr_web, tests.test_arr_web_company_reports).
Full discovery: 348 tests, OK (skipped=10).
Isolated authenticated fake-server browser QA did not upload, extract, delete, activate or generate anything.
At 1280x720: source rail 760px, dropzone 644px, upload action 104px, document scroll width 1280px.
At 390x844: source rail/dropzone 324px, single-column action, document scroll width 390px; fixed-company helper wraps safely under the title.
Browser console warnings/errors: none.
