+# Phase 04 Plan 04: Pipeline Schemas and Class Summary
+
+**Pipeline schemas (PipelineInput/Output/Config) and Pipeline class foundation for processor orchestration**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-13T15:35:50Z
+- **Completed:** 2026-03-13T15:38:24Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- PipelineInput/Output/Config schemas defined in schemas.py
+- Pipeline class with processor initialization and validation
+- URL parsing creates correct content directory
+- All 19 tests passing
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Define Pipeline Schemas** - `5d4cb93` (test) + `789d1f4` (feat)
+2. **Task 2: Create Pipeline class** - `0dfb51e` (feat)
+
+**Plan metadata:** (pending final commit)
+
+_Note: TDD tasks may have multiple commits (test -> feat -> refactor)_
+
+## Files Created/Modified
+- `kb_pipeline/schemas.py` - Added PipelineInput, PipelineOutput, PipelineConfig schemas
+- `kb_pipeline/pipeline.py` - Pipeline class with processor initialization
+- `tests/test_pipeline/test_pipeline.py` - Schema and Pipeline class tests (19 tests)
+
+## Decisions Made
+- Sequential execution pattern for simplicity and debuggability
+- Processor STEP_NAME must match config.steps for validation
+- Content directory naming convention: `{platform}_{content_id}`
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Pipeline foundation ready for run() method implementation
+- Can integrate with existing processors (parse, download, asr, analyze)
+
+## Self-Check: PASSED
+- All files verified to exist
+- All commits verified in git history
