storing actual_region, delivery_area, and screenshot_path is genius because suddenly you've got the breadcrumbs to actually figure out what went sideways when things break. There's definitely a blind spot though around session state management - cookie mess across regions and redirect loops can quietly push your data into the wrong market without you even noticing, and that deserves way more attention in the validation playbook. But swapping request success rate for valid sample rate completely reframes how you think about monitoring, shifting it from questioning is our infrastructure working to 'are we actually getting usable business data? which honestly changes everything. If you're just getting regional monitoring off the ground, this gives you a legit starting point to build from but if you're already running at scale, you're probably gonna need to bolt on extra stuff around retry logic and keeping costs reasonable
