Use case · phase 03

When the prototype disagrees, revise the argument—not just the CAD.

A failed test is useful only when it changes the right assumption. Howard helps connect the observation to the model, update downstream checks, and define what the next revision must prove.

01
Record the test configuration and pass/fail criterion.
02
Compare measured behavior with the prediction and assumptions.
03
Identify which assumption, boundary condition, or property is contradicted.
04
Update only the affected chain of calculations and decisions.
05
State remaining uncertainty and the next discriminating test.

Preserve why the design changed.

The next engineer should not need to reconstruct the failure from chat history and slide decks. Howard keeps the revision tied to the evidence, affected calculations, and unresolved risks.

Bring a test result that changed the design.
