A structured thinking tool for technical fault diagnosis. Drives a Socratic dialogue grounded in two core axioms, then produces a formal incident document.

These two questions constrain the hypothesis space. Return to them whenever the analysis stalls or hypothesis count grows unwieldy.

Axiom 1 — Comparative isolation

"This but not that — why?" What exhibits the symptom? What doesn't? The difference between them is where the cause lives. Force specificity: same network but different host? Same host but different service? Same service but different input?
