LLLin000 5af3a1f8ca feat: asset-internal figure number recovery for rotated vector figures ... adds a metadata-only recovery pass that scans matched figure assets for internal PDF line labels ("Figure N.", "Fig. N:") when the figure lacks a figure_number. new components: - extract_pdf_lines_normalized() in ocr_pdf_spans.py — reads PDF rawdict lines page-by-page, normalizes coordinates to OCR space - _recover_missing_figure_numbers_from_assets() — inventory pass between synthetic fallback and dedup - _needs_asset_internal_figure_number_recovery() — gate supporting both synthetic_figure and figure_unknown entries - _looks_like_internal_figure_label() — regex-based label detection - _asset_edge_band_score() — geometric rejection for center-positioned lines or lines covering >15% asset area - page_pdf_lines_by_page parameter added to build_figure_inventory() verification: U746UJ7G figure_unknown_000 -> figure_002 with recovered label "Plot of Criteria Time". 428 regression tests pass (6 new).		2026-07-02 03:00:33 +08:00
