Approach
Structure before surface.
Each selection maps to a bounded failure class, three evidence checks and one next step. It does not diagnose an unseen system or invent certainty.
Functional demo · Demonstration
A working decision tool that turns an operational symptom into a clear, reviewable next-action path.
Challenge
Goal
Demonstrate a small, useful decision interface that translates an operational symptom into a disciplined investigation path.
Scope
Approach
Each selection maps to a bounded failure class, three evidence checks and one next step. It does not diagnose an unseen system or invent certainty.
Design
A two-panel technical worksheet makes the current selection and result relationship immediately visible while retaining a compact mobile flow.
Engineering
A deterministic client-side state machine with no network dependency, no stored personal data and predictable keyboard behavior.
Key decisions
No AI call for deterministic mapping
No false diagnosis from a single symptom
One visible result at a time
Every path ends in evidence gathering
Functional demonstration
Choose a symptom
Likely investigation path
Run a bounded form and delivery-path diagnosis before changing the design.
