03
A concrete starting point
Project 1–256 finite numbers bounded by ±10^6 onto the nonnegative unit simplex. Test ties and vertex solutions, reject Booleans and compare the floating result with a numerical tolerance without interpreting the weights as calibrated probabilities.
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.

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.
