Worklog for task "Configure Analytics and Launch Quality Control"

Progress as of 09/30/2026

The preparatory phase of analytics and quality control has begun.

The old website baseline preserves browser scenarios, HTTP checks, robots/sitemap, four Lighthouse reports, a container resource snapshot, and material checksums. Current issues that are important to track as regressions have been documented.

Two old Google Analytics connections were found on legacy—a potential source of duplicate events. Part of the interface also depends on the presence of Yandex.Metrica.

The new implementation is already covered by technical checks: npm run types, npm run lint, npm run build, MySQL integration reading, 17 SSR/accessibility/routing tests, and browser navigation via legacy URIs without hydration errors.

Remaining tasks: inventory and migrate actual analytics goals/events, eliminate counter duplication, define lead generation events, check UTM/referrer, test form and lead delivery, and, after launch, monitor actual conversions, 404/5xx errors, and search engine accessibility.
