Implement char-weighted median aggregation of per-span readability scores into a page-level score stored in extraction_quality.readability. Algorithm: - Collect (score, char_count) pairs from spans - Sort by score ascending - Walk sorted list accumulating character counts - Return score at half-total-char position Acceptance criteria: - Single span: returns its score - Multiple spans: char-weighted median (longer spans count more) - Empty page: returns 0.0 - All-perfect: returns 1.0 Closes: pdftract-oh30a Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
