Walk from a recognisable symptom in your data, a report that doesn't match, a join that fails, a dashboard nobody trusts, down through the data layer, the process layer, and the organisational layer that produced it.

HOW THIS WORKS
The same causal graph that powers this diagnostic is published as a flat reference at the four-layer catalogue. The catalogue lists all 34 entries with their causal edges; this tool walks the graph step by step. Each entry on this page is anchorable in the catalogue: for example, same concept, different string resolves to /open-source/the-problem#l1-same-concept-different-string.
Two directions of trace are available. Starting from a symptom (the default) walks upward from a visible business impact toward the organisational root cause that produced it. Starting from a root cause walks downward from a structural condition toward the impacts it produces. Both directions traverse the same edges; the difference is which end you start at.
