Mode 02 · Diagnose
Start from what failed.
Not from a knot name.
01
Symptom
What actually happened on the water.
02
Where it failed
Location outranks the knot you intended to tie.
03
Connection & materials
Refines the cause. Never a library filter.
Connection under stress
Main line
Field notes (optional)
Scenario starters
One tap loads a realistic failure and runs the diagnosis.
How this reads evidence
- →Break location separates line damage from knot geometry from hardware damage.
- →Material system separates user error from a family that was never rated for that line.
- →Connection type weights the causes; it does not filter a catalog.
- →Anything the model cannot verify is reported as unverified, not as a pass.
