How edges in this graph are derivedWI-GRAPH v1.0.0
Species → agent edges come from the WI-SL resistance profile (0–100 ordinal scale derived from EN 350 durability class, extractive chemistry and movement). ≥70 is read as "resists well", 45–69 as "moderately resists", below 45 as "is vulnerable to".
Climate → agent edges fire when a climate's driver value (UV, humidity, salt or freeze-thaw load) is 60 or above, read directly from the climate dataset.
Treatment → agent / standard edges come from the paraphrased standards corpus used across the site (EN 927-1, EN 351-1, EN 350 clause 4, EN 13501-1).
Species → standard edges reuse the exact source list already published for each Global WoodIntel Score sub-score.
