# Handoff: Phase 1 Publishing Pipeline - Subagent-Driven Development

## Task(s)

Implementing Phase 1 of the publishing pipeline refactoring using the **subagent-driven-development** skill. This creates four internal pipeline components (Strategy, Validator, Executor, Notifier) for branch publishing using repository-based architecture.

**Plan document**: `docs/plans/2025-12-14-phase-1-publishing-pipeline-combined-implementation.md`

### Status Summary

| Task | Description | Status |
|------|-------------|--------|
| Task 1-7 | Supporting types & first interfaces | **COMPLETED** (before session) |
| Task 8 | IPublishingExecutor interface | **COMPLETED** |
| Task 9 | IPublishingNotifier interface | **COMPLETED** |
| Task 10-11 | PublishingStrategy & PublishingValidator implementations | **COMPLETED** (before session) |
| Task 12 | PublishingExecutor with IDocumentRepository | **COMPLETED** |
| Task 13 | PublishingNotifier implementation | **COMPLETED** |
| Task 14 | Register pipeline components in DI | **COMPLETED** |
| Task 15 | Add PerformPublishBranchPipelineAsync method | **COMPLETED** |
| Task 16 | Create integration tests | **COMPLETED** |
| Task 17 | Create benchmark infrastructure | **COMPLETED** |
| Task 18 | Run full test suite | **PENDING** |

**Current Phase**: Task 18 (final verification) - need to run full test suite

## Critical References

1. **Implementation Plan**: `docs/plans/2025-12-14-phase-1-publishing-pipeline-combined-implementation.md`
2. **Core CLAUDE.md**: `src/Umbraco.Core/CLAUDE.md` - defines scoping patterns, notification patterns
3. **superpowers:subagent-driven-development skill** - workflow being followed

## Recent changes

All changes committed to `refactor/ContentService` branch:

- `src/Umbraco.Core/Services/Publishing/IPublishingExecutor.cs` - Added interface (Task 8)
- `src/Umbraco.Core/Services/Publishing/IPublishingNotifier.cs` - Added interface (Task 9)
- `src/Umbraco.Infrastructure/Services/Publishing/PublishingExecutor.cs` - Implementation with IDocumentRepository (Task 12)
- `src/Umbraco.Core/Services/Publishing/PublishingNotifier.cs` - Implementation (Task 13)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingExecutorTests.cs` - 4 unit tests
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingNotifierTests.cs` - 3 unit tests
- `src/Umbraco.Infrastructure/DependencyInjection/UmbracoBuilder.Services.cs:92-96` - DI registration
- `src/Umbraco.Core/Services/ContentPublishingService.cs` - Added pipeline fields, constructor params, and PerformPublishBranchPipelineAsync method
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/Publishing/PublishingPipelineIntegrationTests.cs` - 3 integration tests
- `tests/Umbraco.Tests.Benchmarks/ContentPublishingPipelineBenchmarks.cs` - Benchmark infrastructure

## Learnings

1. **ContentValidationResult naming collision**: There are two types with this name in the codebase:
   - `Umbraco.Cms.Core.Models.ContentEditing.ContentValidationResult` (existing)
   - `Umbraco.Cms.Core.Services.Publishing.ContentValidationResult` (new pipeline type)
   - Fixed by using fully qualified names in `ContentPublishingService.cs:199,251,278`

2. **PublishCulture extension method signature**: The real method requires `PropertyEditorCollection` as a parameter, which wasn't in the plan. Had to add this dependency to `PublishingExecutor`.

3. **RuntimeMoniker for .NET 10**: Use `RuntimeMoniker.Net10_0` (not `Net100` as plan stated)

4. **InternalsVisibleTo already configured**: `Umbraco.Core.csproj` already exposes internals to `Umbraco.Infrastructure` at line 54.

5. **Constants.Security.SuperUserId = -1**: Defined in `Constants-Security.cs:11`

## Artifacts

### Implementation Files
- `src/Umbraco.Core/Services/Publishing/IPublishingExecutor.cs`
- `src/Umbraco.Core/Services/Publishing/IPublishingNotifier.cs`
- `src/Umbraco.Infrastructure/Services/Publishing/PublishingExecutor.cs`
- `src/Umbraco.Core/Services/Publishing/PublishingNotifier.cs`
- `src/Umbraco.Infrastructure/DependencyInjection/UmbracoBuilder.Services.cs:92-96`
- `src/Umbraco.Core/Services/ContentPublishingService.cs:32-35,49-52,69-72,383-493`

### Test Files
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingExecutorTests.cs`
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingNotifierTests.cs`
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/Publishing/PublishingPipelineIntegrationTests.cs`
- `tests/Umbraco.Tests.Benchmarks/ContentPublishingPipelineBenchmarks.cs`

### Planning Documents
- `docs/plans/2025-12-14-phase-1-publishing-pipeline-combined-implementation.md`

## Action Items & Next Steps

1. **Run Task 18 - Full Test Suite**:
   ```bash
   dotnet build
   dotnet test tests/Umbraco.Tests.UnitTests --filter "FullyQualifiedName~Publishing"
   dotnet test tests/Umbraco.Tests.UnitTests
   ```

2. **Code Review for Task 17**: Already passed, but was interrupted before marking complete

3. **Update plan document**: Mark remaining tasks as completed once verified

4. **Use finishing-a-development-branch skill**: After Task 18 passes, follow the skill to complete the branch (merge, PR, or cleanup options)

5. **Performance baseline**: After full verification, run the benchmark to establish baseline:
   ```bash
   dotnet run -c Release --project tests/Umbraco.Tests.Benchmarks -- --filter "*PublishingPipeline*"
   ```

## Other Notes

### Performance Gates (from plan)
- Throughput (50+ items): >= 2x improvement over legacy
- Memory allocations: <= legacy
- Correctness: 100% parity with existing tests

### Key Architecture Decisions
- Pipeline components are `internal` (not public API yet)
- Uses `IDocumentRepository` instead of `IContentService` (avoids circular dependencies)
- `PerformPublishBranchPipelineAsync` runs in PARALLEL with legacy path (not replacing it)
- All components registered as **Scoped** services (appropriate for transaction-based operations)
