+
+This UAT release operationalizes LeanSpec's five first principles:

+2. **Signal-to-Noise** - Every word informs decisions
+3. **Intent Over Implementation** - Capture why, not just how
+4. **Bridge the Gap** - Both human and AI understand
+5. **Progressive Disclosure** - Add complexity only when needed
+
+**Notable Completed Specs in this Release:**
+- 063: Migration from existing tools
+- 062: Documentation information architecture v2
+- 061: AI-assisted spec writing
