Learnings

1. Implementation goes in Infrastructure, not Core: The plan specified implementation in Umbraco.Core, but ISqlContext dependency requires implementation in Umbraco.Infrastructure. Interface stays in Core, implementation goes to Infrastructure.

2. InternalsVisibleTo required: Added InternalsVisibleTo for Umbraco.Infrastructure in Umbraco.Core.csproj so Infrastructure can access internal types like PublishingPlan.

3. Baseline performance established: Legacy PublishBranch performance at 50 items = 62.7 items/sec. Target is 2x = 125+ items/sec.

4. Test mocking pattern: For VariesByCulture() extension method, mock the underlying Variations property on ISimpleContentType, not the extension method directly.

5. ContentType creation in tests: Don't use ContentTypeBuilder. Use direct instantiation: new ContentType(ShortStringHelper, -1) { Alias = "...", Name = "...", Variations = ContentVariation.Nothing }

Action Items & Next Steps

1. Resume from Task 6: Read the plan at docs/plans/2025-12-13-phase-1-implementation-fixes.md and continue with Task 6 (Create BatchValidationContext)

2. Follow TDD pattern: For each task, write failing test first, then implementation, then verify tests pass, then commit

3. Use code review after implementation tasks: After Tasks 6, 7, 8 (the main implementation tasks), dispatch a code-reviewer subagent

4. Run performance tests after all tasks: Compare against baseline (62.7 items/sec target: 125+ items/sec)

5. Remaining tasks (6-11):

   • Task 6: Create BatchValidationContext record
   • Task 7: Implement PublishingValidator with parallel processing
   • Task 8: Implement PublishingExecutor with repository batch operations
   • Task 9: Create integration tests comparing pipeline to legacy
   • Task 10: Update benchmark to use .NET 10.0
   • Task 11: Add ContentValidationResult with factory methods

Other Notes

Skill in use: superpowers:subagent-driven-development - Dispatches fresh subagent per task with code review between tasks.
