Task Breakdown

What specific work needs to be done?

Phase 1: Foundation

• Task 1.1: Define ValidationFailure and ValidationResult dataclasses (Done).
• Task 1.2: Implement CompletenessChecker class skeleton (Done).
• Task 1.3: Integrate text_segmenter inside the checker (Done).

Phase 2: Core Logic

• Task 2.1: Implement the search loop with sliding search cursor (Done).
• Task 2.2: Add score calculation and noise filtering (Done).
• Task 2.3: Implement _fuzzy_check for token-based matching to handle embedded noise/artifacts.

Phase 3: Testing & Optimization

• Task 3.1: Unit tests with synthetic strings (Done).
• Task 3.2: Integration test using real PDF/EPUB fixtures (Done - 100% score).
• Task 3.3: Debug and resolve false negatives caused by header/footer artifacts.

Timeline & Estimates

• Completed 2025-12-30.

Risks & Mitigation

• Risk: Slight extraction differences blocking exact matches.
• Mitigation: Implemented token-based (85% threshold) fuzzy search fallback.
• Risk: High memory usage for very large books.
• Mitigation: The checker uses a sliding window search current_pos and local fuzzy search window (10k chars) to keep performance high.
