Fault Hypothesis Builder
Describe a fault in six structured fields; a fixed rule set ranks hypotheses to test - with the evidence to collect, what would support each, and what would weaken it. Advisory structure, never a diagnosis.

Layer clues you have observed (all that apply)
Optional detail for the export (does not affect the ranking)
These lines are copied verbatim into the worksheet's Situation section so a ticket or TAC case starts complete.
Runs entirely in your browser. The free-text notes flow only into the exported worksheet - they never influence the ranking, and nothing is uploaded.
Pick what you are seeing above and the hypotheses to test appear here - ranked, with evidence, live as you refine.
