Normalize picture-text and numeric cleanup, recover mojibake pages, keep chart labels in chunks, and enable keyword+vector hybrid expand for agent search without eval-shaped age-band post-processing.
Avoids an unnecessary rename that noisied the PR diff.
Restore the original OCR figure comment in the chunker to avoid noisy comment-only diff.
… docs. No measured accuracy gain from these settings in Toppan runs; keep extract/chunk product fixes only.

Summary
category: valuetranscription, not trend-only summaries.hybrid_searchnow honorshybrid_expand/hybrid_methodfrom graph config, and keeps keyword seeds if vector seeding fails.Why this helps
Better extract → more exact facts in chunks. Hybrid expand (keywords + vector) → agent is more likely to retrieve those chunks for table/chart questions. Together this raises grounded answer quality without question-specific hacks.
