window- Analysis window.Default: last 30 days.

Conclude
Item-level conclusions inherit the gap: bound them explicitly or fix first.
Evidence every conclusion must carry
- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.
Where the agent stops
- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.
How it goes wrong quietly
The cases where the analysis is wrong and still looks right. Read them before trusting a number.
- Returns and cancellations post late or never: GA4 revenue is gross-at-event, not finance's number.
