03
A concrete starting point
Multiply two four-component Hamilton quaternions in scalar-first order with finite components bounded by ±10^6. Test identity and reversed basis products, rejecting Boolean components without silently normalizing inputs or claiming unit rotations.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.

v, i, j, k = b
return (w*v-x*i-y*j-z*k, w*i+x*v+y*k-z*j,
w*j-x*k+y*v+z*i, w*k+x*j-y*i+z*v)
The example is a starting point for a real project, not a claim that generated code is already tested. Adjust paths, dependencies and expected behavior to match your application.
