The feature_marketing.* and funnel.* events are written to logs/analytics.log, with daily files at logs/analytics-YYYY-MM-DD.log. app.log keeps errors, refusals and changes. Refused and failed requests to /feature-marketing-event stay in app.log. Both logs carry the same request uid. Crawler traffic is not filtered; docs/LOGGING.md lists which funnel steps it reaches.
Visitor-counting events moved to their own log
Feature page and signup funnel events are written to analytics.log instead of app.log.
