 **Note**: Full end-to-end testing requires .NET 9 SDK in CI environment. Local environment has .NET 8 so cannot test compilation, but syntax and structure validation completed.
 
+**Status**: Done

 ## Phase 6: Owner Acceptance
 ### Demonstration
-- TBD
+All GitHub workflow fixes have been implemented and committed. The changes include:
+
+1. **Fixed all .NET version inconsistencies** across 7 workflow files
+2. **Corrected build artifact paths** from `net8.0` to `net9.0`
+3. **Fixed critical Aspire version mismatch** that would cause runtime failures
+4. **Updated all user documentation** for consistency
 
 ### Owner Feedback
-- TBD
+- Awaiting feedback from @devstress
 
 ### Final Approval
-- TBD
+- Pending owner review
 
 ## Lessons Learned & Future Reference (MANDATORY)
 ### What Worked Well
-- TBD after completion
+- **Systematic approach**: Analyzing all files first, then implementing changes methodically
+- **Validation strategy**: Using grep commands to verify no references remain and new references are in place
+- **Comprehensive scope**: Not just fixing workflows but also documentation for consistency
+- **Critical issue discovery**: Found and fixed Aspire version mismatch that wasn't in original scope
 
 ### What Could Be Improved  
-- TBD after completion
+- **Earlier documentation scan**: Could have identified documentation issues in initial analysis
+- **Version validation**: Could have cross-referenced project files earlier to catch version mismatches
 
 ### Key Insights for Similar Tasks
-- TBD after completion
+- **Framework upgrades require comprehensive updates**: Not just runtime versions but also build paths, package versions, and documentation
+- **CI/CD pipelines are sensitive to path changes**: Build artifact paths must exactly match the new framework target
+- **Version consistency is critical**: Hardcoded version paths in workflows must match actual package versions
+- **Documentation updates are part of the fix**: User-facing docs must be updated for credibility and accuracy
 
 ### Specific Problems to Avoid in Future
-- TBD after completion
+- **Don't assume workflows only need runtime version updates**: Build artifacts, upload paths, and package versions also need updates
+- **Don't skip documentation updates**: Inconsistent version references in docs confuse users
+- **Always cross-reference hardcoded versions**: Workflows with hardcoded package versions must match project files
+- **Validate changes comprehensively**: Use grep and other tools to ensure complete migration
 
 ### Reference for Future WIs
-- TBD after completion
+- **Framework upgrade pattern**: Update runtime → build paths → package versions → documentation → validate
+- **Validation commands**: Use `grep -r "old_version" .` and `grep -r "new_version" .` to verify migration
+- **Critical files to check**: Project files (.csproj), workflows (.yml), README files, and wiki docs
+- **Aspire integration**: Version paths in workflows must match actual installed package versions
