PRACTICE LAB / 6.0.0

# When no design fits

Understand why rejecting an impossible request is a useful engineering result.

## Follow the work.

No proprietary uploads required. Public synthetic examples; a verified organization account is required to save runs.

01

### Load the default scenario.

02

### Require three independent failure domains although the input has only two.

03

### Run the workflow. It must stop at resource selection.

04

### Inspect the blocked verdict and confirm no model plan was fabricated.

EXPECTED OUTCOME

### The result is blocked and no downstream model plan is claimed.
