Senior verification work decides what to build, in what order, and when the evidence supports sign-off. A living plan, a deliberate method mix, honest metrics, and explicit risk calls carry a block from specification to done.

(loop back on every spec change)Lesson | What it decides |
|---|---|
Feature rows, risk rank, ambiguity log, and review gates. | |
Directed, random, formal, or emulation per feature class and level. | |
Phase exits, the weekly dashboard, and audits that keep metrics honest. | |
Spec changes, capacity, descoping waivers, and the evidence bundle. |
No. The row names no stimulus and no check. Split it until each row pairs one behavior with one check and one coverage point.
