Foundational Claim-Evidence Matrix — Verification Report (Batch 1)
Book-anchor note: The Victor C. Li 2019 book is the Atlas's primary anchor. This foundational-paper matrix is the supporting / verification layer that verifies and deepens the book-anchored Atlas claims.
Scope
First verification pass over 07_visualization/foundational_papers_claim_evidence_matrix.csv targeting rows tagged needs_page_verification (3) and needs_figure_table_verification (5), plus a DOI / bibliographic ledger for six key papers.
Initial status counts (70 rows)
- verified_from_source_note: 62
- needs_figure_table_verification: 5
- needs_page_verification: 3
Final status counts (70 rows, no rows added or removed)
- verified_from_source_note: 62
- verified_from_full_text: 7
- needs_page_verification: 1
Rows promoted to verified_from_full_text
| Row | paper_id | Claim (short) | Full-text evidence location |
|---|---|---|---|
| 5 | li_leung_1992 | Uniaxial tension is the reference loading condition for PSH | Introduction and Bridging-Stress section, extracted_text lines 15-18, 34; framed explicitly as uniaxial tension. |
| 10 | lin_li_1997 | Composite fracture energy predictable from single-fiber pullout | Section 5.2 'Composite fracture energy', p.175, Eqs. (22)-(23); extracted_text lines 683-698. |
| 30 | kanda_li_2006 | Practical PSH criteria sigma_peak/(sigma_fc)_i > 1.3 and J'b/Jtip > 2.7 | Extracted_text line 2491 (conclusions) with derivation via Fig. 16 (lines 2263-2272) and Fig. 17 (lines 2278-2296). |
| 35 | li_wang_2006 | 7 vol% 4 mm plastic beads suppress scatter | Fig. 12 caption verbatim in extracted_text lines 355-357; body lines 319-321. |
| 39 | li_wang_2006 | Fig. 1 vs Fig. 12 demonstrate scatter and its suppression | Extracted_text lines 319-321, 355-357 confirm both figures. |
| 48 | zhou_etal_2012 | alpha ~+8% at w/p=0.30 and ~+24% at w/p=0.35 with adjusted mixing | Extracted_text lines 165-166 (w/p assignments) and 370-371 (verbatim 8% / 24% statement). |
| 53 | li_li_2012 | Marsh cone 24-33 s window yields alpha≈0.8 and strain≈3% | Extracted_text lines 914-915 (optimal range statement), Table 3 lines 708-736 (numeric values), and Fig. 12 references lines 887, 957-963. |
Rows still unresolved
| Row | paper_id | Status | Reason |
|---|---|---|---|
| 2 | li_leung_1992 | needs_page_verification | Closed-form delta_cu = tau L_f^2 / (E_f d_f): the extracted OCR for Li & Leung 1992 is heavily garbled around the delta* / d_f / E_f expressions (see extracted_text lines 34-45), so the exact algebraic form cannot be independently confirmed from full text without re-OCR or manual PDF read. The claim is left at needs_page_verification; the source note still supports it, but per constraints we do not promote without direct full-text confirmation. |
Recommended next step: re-extract the Li & Leung 1992 PDF with an OCR pass optimized for equations (e.g., mathpix or a table-aware pdftotext -layout run limited to pp. 2247-2249), then re-check row 2.
DOI / bibliographic ledger summary
See 03_papers/foundational_bibliographic_verification_ledger.md. All six target papers currently sit at needs_external_check except li_wang_wu_2001, whose source-note YAML already carries DOI 10.14359/10724; per constraints (no fabrication, no unverified insertion) no new DOI was written into any card in this pass.

Recommended next task
Batch 2: re-OCR / manual PDF read of Li & Leung 1992 pp. 2247-2249 to close the remaining row (delta_cu formula), and an external DOI lookup pass (Crossref) for the five needs_external_check papers.
