Blackdeck now has a 60-day global-risk baseline and live risk map, while ByteCosmos has a real-time crypto dashboard and a completed 200-day Upbit baseline.

A calendar UX pass, the reasoning behind Blackdeck snapshot gating, and the root cause of ByteCosmos page latency.

The data model and operational design behind the calendar, posts, reminders, privacy controls, and SEO.
