Interview Prompt
A real production diagram with four sources, a layered architecture, and two consumers is on the canvas. The section named five annotations a complete diagram must encode; the boxes-and-arrows version already covers two of them. Add the section's third annotation (cadence) on each source so on-call can tell at a glance which source to investigate first when freshness is missed. At least three distinct freshness tiers should be visible across the four sources.
