Debug

Overview

Fuses systematic root-cause debugging with verification-before-completion.

Core principle: evidence before fixes; evidence before "fixed" claims.

Announce: "Using debug to …"

When to Use

• Any bug, flaky test, build/CI failure, unexpected behavior, performance mystery
• Especially under time pressure ("just one quick fix")
• Before claiming "done" / "passing" / "fixed"

When NOT to use: pure greenfield feature with no failure (use grill / write-plan / tdd).
