# Marketing Report Definition Check

## Inputs
Approved source exports with extraction date, timezone, reporting window, currency, filters, metric definitions, attribution setting and comparison period. Use anonymized data where possible.

## Workflow
1. Inventory the exports and record their date ranges, timezone, filters and metric definitions. Mark any missing definition unknown. Do not assume clicks, sessions and users are interchangeable.
2. Calculate totals from source rows. Compare periods only when duration, filters and definitions match; do not sum overlapping summaries or divide by a missing denominator.
3. Separate observed outcomes from attributed outcomes. Record the source attribution model for key events and flag model changes before comparing conversions. Correlation is not proof that a campaign caused the result.
4. Return a reconciled metric table and an exception ledger. Explain which conclusions the data supports, which comparisons must wait and which source to request next. Do not change tracking or budgets.

## Output contract
metric | source/window | definition | actual | comparison | change | comparable? | evidence | exception

## Fictional acceptance test
Fictional weekly export A has 100 clicks and 5 key events; export B has 80 clicks and 4 key events. Both use the same seven-day window length and definition: each event rate is 5%, a zero percentage-point change. Clicks grew 25%. If B uses a different attribution model, report the click comparison but mark the key-event comparison not comparable.

## Review gates
Recompute numerators and denominators, distinguish percent change from percentage points, and check the attribution model on both periods. An incomplete dataset gets an exception, not a guessed metric.
