Full Graph — Foundational Pass

Book-anchor note: "Foundational" in this filename refers to the foundational-paper support layer, not to the Atlas's primary foundation. The Atlas's primary anchor is the Victor C. Li 2019 book; the edges here connect Atlas concept nodes to their supporting foundational-paper cards.

Purpose: human-readable companion to 07_visualization/full_graph_foundational.json. Consolidates high-level ECC concept graph with the five new concept nodes and the foundational edges promoted from candidate to confirmed on the basis of the foundational paper cards.

Do not overwrite concept_graph_expanded.json. This is an additive artifact.

Confirmed foundational edges (promoted or newly added, confirmed)

Group A — status flipped from candidate to confirmed in full_graph_candidate_edges.csv:

1. micromechanics_based_design → fiber_bridging_law (uses) — lin_li_1997; yang_2008; li_2002
2. strain_hardening_criteria → fiber_bridging_law (requires) — yang_2008; lin_li_1997
3. fiber_bridging_law → distributed_microcracking (controls) — yang_2008; li_wang_wu_2001
4. strain_hardening_criteria → distributed_microcracking (enables) — li_wang_wu_2001
5. strain_hardening_criteria → direct_tensile_test (measured_by) — li_wang_wu_2001; yang_2008

8. distributed_microcracking → crack_width_distribution (characterized_by) — li_wang_wu_2001
9. crack_width_distribution → transport_properties (reduces) — yang_2008

Group B — appended to full_graph_candidate_edges.csv with status confirmed:

• interface_properties → strain_hardening_criteria (affects) — redon_2001; li_2002
• surface_treatment → interface_properties (modifies) — redon_2001; li_wang_wu_2001; li_2002
• matrix_micro_spalling → fiber_bridging_law (affects) — yang_2008
• cook_gordon_effect → fiber_bridging_law (affects) — yang_2008
• two_way_debonding → fiber_bridging_law (affects) — yang_2008
• scale_linkage → micromechanics_based_design (supports) — yang_2008; li_wang_2006

Candidate edges not yet verified (unchanged)

• micromechanics_based_design → strain_hardening_criteria (enables)
• micromechanics_based_design → flaw_design (uses)
• micromechanics_based_design → fiber_dispersion (depends_on)
• strain_hardening_criteria → flaw_design (uses; strength criterion)
• fiber_bridging_law → fiber_dispersion (depends_on)
• distributed_microcracking → tension_stiffening (supports)
• tension_stiffening → resilience (supports)
• long_term_strain_capacity → durability (supports)

Additional Tier 2–4 candidate edges are retained in full_graph_candidate_edges.csv without change.

Notes on evidence

• All evidence references are paper card filenames under 03_papers/. Numerical values inside the paper cards that are still needs verification are not treated as verified here; only the qualitative relations are confirmed.
• DOI, page numbers, figure numbers, and specific numerical thresholds remain marked needs verification in the underlying paper cards.
