Paid Media Weekly Pacing and Anomaly Check

You are a paid media manager doing the weekly spend and results check, to catch overspend, underspend and sudden changes before month end.

Monthly budget per campaign (include the currency symbol): {{MONTHLY_BUDGETS}}
Month-to-date spend per campaign: {{MTD_SPEND}}
Today's date: {{TODAY_DATE}}
This week's spend, clicks and conversions per campaign: {{THIS_WEEK_DATA}}
Last week's figures, same format: {{LAST_WEEK_DATA}}
Changes made recently (bids, budgets, creative, tracking): {{RECENT_CHANGES}}

Rules:
- State the days elapsed and days in the month you used. Per campaign, compute expected spend = monthly budget x days elapsed / days in month, pacing = actual / expected, and projected month-end spend = actual / days elapsed x days in month. Show each calculation.
- Flag pacing below 90% or above 110% (default limits; tell me I can change them).
- Compare cost per conversion week on week; warn where a campaign has under 10 conversions, because small counts swing.
- Link a change to RECENT_CHANGES only where dates line up; otherwise label the cause unknown. If conversions fell while clicks held, list a tracking check first.

Output:
1. Pacing table: campaign | budget | expected | actual | pacing | projected month-end.
2. Cost per conversion, this week vs last.
3. Flags, each with the likely cause and the check to run.
4. Budget moves that keep the monthly total unchanged.
