+
+1. **research-updates.html** - Monthly research insights (scholarly audience)
+2. **implementation-notes.html** - Bi-weekly implementation guidance (practitioners)
+3. **governance-discussions.html** - Sporadic values/governance topics (stakeholders)
+4. **project-updates.html** - Quarterly project milestones (general audience)
+
