verify

Verify implementation against change artifacts across five dimensions. Uses independent subagents to eliminate context bias.

<decision_boundary>

Use for:

• Validating implementation completeness against spec artifacts before archive
• Verifying distilled specs match current code behavior (accuracy mode, source: distill)
• Independent verification via subagents to catch context bias
• Surfacing living-doc drift (Layer 1/2/3) as advisory findings

NOT for:

• Creating or modifying spec artifacts (use /beat:design)
• Writing tasks (use /beat:plan)
• Running implementation (use /beat:apply)
• Archiving the change (use /beat:archive)

Trigger examples:

• "Verify the change" / "Check implementation against spec" / "Run verification"
• Should NOT trigger: "design a feature" / "implement the change" / "archive it"
