Constrained surfaces expose bounded meaning and action

Glanceable, live, and system-mediated surfaces prioritize identity, value, freshness, privacy, and direct handoff.

Guidance

Do

  • Declare freshness and lifecycle
  • Deep-link to the exact entity or task

Do not

  • Shrink an app screen into a widget or imply stale data is live

Verification contract

surface lifecycle, privacy, localization, and deep-link matrix
