Phase 04 Plan 01: BaseProcessor and ParseProcessor Summary

Unified BaseProcessor abstract class and ParseProcessor implementation establishing the foundation for pipeline architecture

Performance

• Duration: 5 min
• Started: 2026-03-13T15:09:46Z
• Completed: 2026-03-13T15:14:40Z
• Tasks: 3
• Files modified: 6

Accomplishments

• BaseProcessor abstract class defining unified interface for all processors
• ParseProcessor correctly wrapping LinkParser for Bilibili/Zhihu URL parsing
• ParseInput/ParseOutput schemas with proper validation
• All processors exportable from kb_pipeline.processors module

Task Commits

Each task was committed atomically:

1. Task 1: Define BaseProcessor abstract class - 3ad2576 (test/feat)
2. Task 2: Add ParseInput and ParseOutput schemas - efddef9 (feat)
3. Task 3: Implement ParseProcessor with __init__.py export - 06d36fc (feat)

Plan metadata: pending (docs: complete plan)

Note: TDD tasks may have multiple commits (test -> feat -> refactor)

Files Created/Modified

• kb_pipeline/processors/base.py - Abstract base class with STEP_NAME and process() method
• kb_pipeline/processors/parse.py - ParseProcessor wrapping LinkParser
• kb_pipeline/processors/__init__.py - Module exports (BaseProcessor, ParseProcessor, ASRProcessor)
• kb_pipeline/schemas.py - Added ParseInput and ParseOutput schemas
• tests/test_processors/test_base.py - Tests for BaseProcessor abstract behavior
• tests/test_processors/test_parse.py - Tests for ParseProcessor URL parsing

Decisions Made

• BaseProcessor uses ABC with @abstractmethod to enforce process() implementation
• STEP_NAME as class attribute (matches existing ASRProcessor pattern)
• ParseInput content_id/platform default to empty (populated after parsing)
• No retry logic in BaseProcessor (belongs in concrete implementations)
• State recording optional (only when state_manager provided)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Test mock path needed adjustment: mock kb_pipeline.processors.base.get_settings instead of kb_pipeline.processors.parse.get_settings because BaseProcessor.init calls get_settings()

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Processor interface established, ready for additional processor implementations
• ParseProcessor provides URL parsing for downstream download/ASR steps
• State management integration tested and working
