 ## What This Enables
 
-After this sprint:
 - projman orchestrator's `Domain/Data` gate checks resolve to `/data-gate`
 - No more "gate unavailable" warnings for data domain issues
 - Data changes get automated validation during sprint execution
 - Standalone `/data-review` available for manual audits
 
-## Validation Checklist
+## Lessons Learned
 
-- [ ] `./scripts/validate-marketplace.sh` passes
-- [ ] `./scripts/verify-hooks.sh` passes
-- [ ] `/validate-contracts` shows no conflicts
-- [ ] `/data-review ~/personal-portfolio/dbt/` produces valid report
-- [ ] `/data-gate` returns PASS on healthy dbt project

+
+**Key Insights:**
+1. Detailed implementation spec documents accelerate planning
+2. Pattern replication from existing implementations (viz-platform) ensures consistency
+3. Additive architecture design enables clean integrations
