Interesting - Channel A only has 2 days of data (9/22 and 9/23), while B and C have the full week (9/22-9/26). Let me check if there's more data or if this is intentional incomplete data.
Channel A: 9/22: 60, 9/23: 58 - missing 9/24, 9/25, 9/26
Channel B: 80, 75, 90, 88, 95
Channel C: 120, 132, 128, 140, 135
For the weekly report for management, I should note the missing data for Channel A.
Let me calculate totals:
Channel A: 60+58 = 118 (only 2 days)
Channel B: 80+75+90+88+95 = 428
Channel C: 120+132+128+140+135 = 655
Weekly grand total (available data): 118+428+655 = 1201
For Channel A, if we only have 2 days, we shouldn't invent the missing days. The report should show what's available and note the gaps.
Looking at the data more carefully - the user said "三个渠道的日销量" and "本周(9/22-9/26)周报". Today is 9/25 according to the system, so 9/26 might be future... wait the user said 9/22-9/26 and the data has 9/26. Today is 2026-09-25. So 9/26 is tomorrow but data exists for B and C. Fine.
I'll create weekly.md with:
1. Each channel daily table
2. Weekly totals
3. Brief commentary for management
For Channel A missing data - I should mark as missing/N/A and note it in commentary.
Let me also double-check if channel_A is really incomplete - maybe I should look at file size again. channel_A.csv is 85 bytes, only 2 data rows. Yes incomplete.
I'll write a clean management-friendly weekly report in Chinese since the user wrote in Chinese.
数据已读完:A 渠道只有 2 天,B/C 有完整 5 天。正在汇总并写 `weekly.md`。
