Step 6 always persists .claude/apex/docs/verify-{task-slug}.md -- an in-context "it works" declaration doesn't survive a session boundary, and this artifact is what later gates (sniper, elicitation) actually check. It sits between eLicit and eXamine in APEX: a task is only complete when both verification and sniper pass.

Verification Before Completion

Overview

Sniper validates CODE QUALITY. Verification validates FUNCTIONAL RESOLUTION. Both are needed before closing any task.

Sniper catches linter errors, SOLID violations, and code style issues. Verification ensures the original request is actually fulfilled -- the right behavior, the right output, the right fix. A task can pass sniper with zero errors and still be functionally wrong.
