Foundational Paper Graph Edge Promotion Plan
Purpose: enumerate candidate edges in 07_visualization/full_graph_candidate_edges.csv (and adjacent implied edges) that can now be promoted from candidate to confirmed on the basis of the five newly created foundational paper cards, and specify the evidence paper card for each.
Policy for this pass:
- Only edges whose source and target rows already exist in full_graph_candidate_edges.csv and where the change is a simple status flip are marked "safe to flip now".
- Edges implying new source/target nodes (for example an interface_properties concept node that does not yet exist) are recorded as "defer" — they must wait for a subsequent automated pass that also creates the missing nodes.
A. Edges safe to promote from candidate to confirmed now
Each row below refers to an existing row in full_graph_candidate_edges.csv.
| # | Source | Target | Relation | Evidence paper card | Rationale |
|---|---|---|---|---|---|
| 1 | micromechanics_based_design | fiber_bridging_law | uses | 03_papers/lin_li_1997_crack_bridging_slip_hardening.md; 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md; 03_papers/li_wu_wang_etal_2002_interface_tailoring_pva_ecc.md |
Design uses sigma(delta) explicitly. |
| 2 | strain_hardening_criteria | fiber_bridging_law | requires | 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md; 03_papers/lin_li_1997_crack_bridging_slip_hardening.md |
J_b' (energy criterion) and sigma_0 (strength criterion) are derived from sigma(delta). |
| 3 | fiber_bridging_law | distributed_microcracking | controls | 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md; 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md |
Shape of sigma(delta) controls saturated multiple cracking; sub-100 um and ~60 um crack widths reported. |
| 4 | strain_hardening_criteria | distributed_microcracking | enables | 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md |
Saturated multiple cracking (spacing 1-2 mm) directly observed when both PSH criteria are met. |
| 5 | strain_hardening_criteria | direct_tensile_test | measured_by | 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md; 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md |
Tensile strain > 4 percent, sigma_cu ~4.5 MPa measured on dogbone tension. |
| 6 | direct_tensile_test | strain_hardening_criteria | measures | 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md |
Same evidence, reverse direction of measurement relation. |
| 7 | direct_tensile_test | crack_width_distribution | observes | 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md; 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md |
Individual crack width below 100 um; ~60 um in Yang 2008. |
| 8 | distributed_microcracking | crack_width_distribution | characterized_by | 03_papers/li_wang_wu_2001_pva_ecc_tensile_strain_hardening.md |
Saturated multiple cracking characterized by crack width distribution < 100 um. |
| 9 | crack_width_distribution | transport_properties | reduces | 03_papers/yang_etal_2008_fiber_bridging_constitutive_law.md |
Yang 2008 explicitly links tight crack width to lower permeability and corrosion resistance (source note Section 4). |
Recommendation: apply these 9 status flips in a subsequent focused pass that edits only the status column of existing rows in full_graph_candidate_edges.csv, appending the evidence paper card filename to the notes column. This pass does not restructure the CSV.
B. Edges to add later (defer; require new nodes or new rows)
These are supported by the new paper cards but the target/source node or the CSV row does not yet exist. They should be added by a subsequent pass that also creates the necessary 02_concepts/* nodes.
| # | Source | Target | Relation | Evidence paper card | Blocker |

| B1 | interface_properties | fiber_bridging_law | inputs_to | 03_papers/redon_etal_2001_pva_interface_properties.md; 03_papers/lin_li_1997_crack_bridging_slip_hardening.md |

Row may not exist in CSV; check and add. |
C. Recommendation on full_graph_candidate_edges.csv
Do not modify full_graph_candidate_edges.csv in this pass. Reasons:
- Some target rows for group A above may need
notescolumn expansion, which is not a purestatusflip and risks breaking column alignment if done ad hoc. - Group B introduces new nodes and new rows, which is a restructuring change and should be batched with the creation of the missing concept nodes.
Leave both A and B for a subsequent automated pass whose only job is to (i) flip status from candidate to confirmed for the 9 rows in group A while appending the evidence paper card filename to notes, and (ii) after creating the missing concept nodes, append the group B edges as new rows with status = confirmed and the appropriate evidence paper card in notes.
