Verify implementation against change artifacts across five dimensions. Uses independent subagents to eliminate context bias. Writes findings to so can act on them without a human relaying them. <decision boundary Use for: - Validating implementation completeness against spec artifacts before archive - Verifying distilled specs match current code behavior (accuracy mode, ) - Independent verification via subagents to catch context bias - Re-verifying after fixes (incremental: only what changed since the last run) - Surfacing living-doc drift (Layer 1/2/3) as advisory findings NOT for: - Creatin…
