Foundational Paper Integration Report

Book-anchor note: The Victor C. Li 2019 book (Springer, DOI 10.1007/978-3-662-58438-5) is the Atlas's primary anchor. The 13 foundational papers below are the supporting / verification layer beneath that book anchor, not the Atlas foundation itself. This report tracks how those supporting papers are integrated.

Snapshot after promoting the five remaining foundational-paper source notes into paper cards. All 13 preserved foundational papers now have paper cards in 03_papers/.

2. Paper cards in `03_papers/` (13 of 13)

All 13 foundational papers now have a paper card:

li_leung_1992_steady_state_multiple_cracking.md
lin_li_1997_crack_bridging_slip_hardening.md (new this pass)
redon_etal_2001_pva_interface_properties.md (new this pass)
li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md (new this pass)
li_wu_wang_etal_2002_interface_tailoring_pva_ecc.md (new this pass)
wang_li_2004_tailoring_preexisting_flaws.md
kanda_li_2006_practical_design_criteria_psh.md
li_wang_2006_microstructure_variability.md
yang_etal_2008_fiber_bridging_constitutive_law.md (new this pass)

Full listing with source paths and Atlas node links is maintained in 03_papers/foundational_paper_cards_index.md.

3. Remaining evidence gaps

Exact page numbers, figure numbers, and table numbers in each new paper card remain "as read from source note / PDF extraction" and are marked needs verification inside each card; they must be verified against the original PDF before being quoted into higher-order Atlas nodes.
DOI checks are still open for Lin 1997, Redon 2001, Li 2002, Kanda 2006, and Yang 2008. Li, Wang & Wu 2001 lists DOI 10.14359/10724 from the source note and still needs independent verification.
The claim-evidence matrix at 07_visualization/chapter2_chapter4_claim_evidence_matrix.csv has not yet been expanded with rows tying the five newly promoted paper cards to their concept nodes (fiber_bridging_law, strain_hardening_criteria, micromechanics_based_design, distributed_microcracking, crack_width_distribution).
Concept-level 02_concepts/interface_properties.md and 02_concepts/surface_treatment.md nodes do not exist yet; several of the new paper cards imply candidate edges that would land on these nodes.
Graph edge promotions implied by the new cards are enumerated in 07_visualization/foundational_paper_graph_edge_promotion_plan.md. full_graph_candidate_edges.csv has not been restructured in this pass.

4. Recommended next Claude task

Priority order:

Verify DOIs, page numbers, figure numbers, and quoted numerical claims (sigma_cu 4.5 MPa, strain > 4 percent, G_d 4.5 -> 2.1 J/m^2, crack width around 60 um, 100 um saturated cracking, spacing 1-2 mm) against the original PDFs and mark the corresponding lines in each paper card as verified.
Add claim-evidence matrix rows for the five newly promoted foundational papers.
Apply the edge status changes listed in 07_visualization/foundational_paper_graph_edge_promotion_plan.md to full_graph_candidate_edges.csv (either through a targeted CSV edit that only flips status for existing rows, or by adding new rows for edges not yet present).
Create concept nodes 02_concepts/interface_properties.md and 02_concepts/surface_treatment.md and re-run cross-link updates.

5. Claim-evidence matrix pass (this update)

Created 07_visualization/foundational_papers_claim_evidence_matrix.csv (UTF-8-sig).
Total data rows: 70 (plus header) — exceeds the 60-row minimum.
All 13 foundational papers appear in the matrix (row counts range 4 to 7 per paper).
All required Atlas nodes appear in the matrix: strain_hardening_criteria (12), fiber_bridging_law (9), flaw_design (8), micromechanics_based_design (6), direct_tensile_test (6), interface_properties (6), fiber_dispersion (5), processing_rheology (5), distributed_microcracking (4), crack_width_distribution (2). Additional nodes carried in the matrix: surface_treatment (3), pseudo_strain_hardening_index (1), two_way_debonding (1), matrix_micro_spalling (1), cook_gordon_effect (1).
Status distribution: 62 rows verified_from_source_note, 5 rows needs_figure_table_verification, 3 rows needs_page_verification, 0 rows verified_from_full_text (pending full-text spot checks), 0 rows needs_doi_or_bibliographic_verification (still tracked in Section 3 above).
Companion reports produced in this pass:
07_visualization/concept_evidence_coverage_report.md — row counts by Atlas node, strongest / weakest nodes, seed-vs-paper coverage, recommendations.
03_papers/foundational_paper_evidence_ledger.md — per-paper summary of main claim contribution, Atlas nodes supported, evidence-row count, unresolved verification needs.

6. Next verification tasks (added by this pass)

Priority order (finer-grained than Section 4):

Resolve the 3 needs_page_verification rows and the 5 needs_figure_table_verification rows by grepping the corresponding .txt files under 00_sources/foundational_papers/extracted_text/ for the specific numeric constants (e.g. 4.5 MPa, 4.679 MPa, 24-33 s, R^2 = 0.98) and figure tokens (Fig. 12, Table 3, Eq. (2)), then promote confirmed rows from verified_from_source_note to verified_from_full_text.
Resolve the still-open DOIs for Lin 1997, Redon 2001, Li 2002, Kanda 2006, Yang 2008, and independently verify DOI 10.14359/10724 for Li Wang Wu 2001. Any DOI that cannot be recovered from Crossref / journal metadata should be tagged needs_doi_or_bibliographic_verification on the corresponding rows in the matrix.
Cross-corroborate the four single-paper concepts (two_way_debonding, matrix_micro_spalling, cook_gordon_effect, pseudo_strain_hardening_index) by identifying at least one supplementary paper each, and add rows in a follow-up pass (matrix expansion, not concept-node edits).
Add crack-width rows to crack_width_distribution from foundational papers already in scope (Li & Wang 2006, Li & Li 2012) where crack pattern is documented but not yet extracted.
Only after (1)-(4), promote strongly-corroborated rows into the concept nodes' "Foundational evidence" sections. Concept nodes were not edited in this pass.
