- Systematic review across 6 lenses
- Severity classification (sound/ambiguous/incorrect)
- Impact categorization (low/structural/systemic)

Run explicitly when you want a thorough review before final QA.
Use when: Reviewing content for semantic SEO quality
Analyzes page content for SPO (Subject-Predicate-Object) triple quality:
- Flags vague predicates ("helps", "improves", "enables")
- Identifies unfalsifiable claims ("trusted by...", "leading provider")
- Catches missing objects and disconnected entities
- Produces summary table + section-by-section breakdown
Analysis only - waits for explicit approval before suggesting rewrites.
