+# [V] Validate — Quality Audit
+
+**Goal:** Systematically audit page specifications for completeness, consistency, and quality.
+
+**When to use:** After completing page specifications, or at any point to check quality.
+
+---
+
+## INITIALIZATION
+
+Read design log at `{output_folder}/_progress/00-design-log.md` before starting.
+
+### Configuration Loading
+
+1. Load project config
+2. Locate page specifications at `{output_folder}/C-UX-Scenarios/`
+3. Begin: Load and execute `./steps-v/step-01-page-metadata.md`
+
+**Reference data:**
+- `./data/quality-guide.md`
+- `./data/validation-standards.md`
+- `./templates/diagnostic-report-template.md`
+
+---
+
+## Validation Sequence
+
+Execute each step in order. Each step produces a section of the validation report.
+
+| Step | Name | Validates |
+|------|------|-----------|
+| 01 | Page Metadata | Title, URL, purpose defined |
+| 02 | Navigation | Entry/exit points, breadcrumbs, nav items |
+| 03 | Page Overview | Overall structure and flow |
+| 04 | Page Sections | Each section complete and ordered |
+| 05 | Section Order | Logical progression |
+| 06 | Object Registry | All components registered |
+| 07 | Design System Separation | Components vs. page-specific |
+| 08 | SEO Compliance | Headings, meta, keyword alignment |
+| 09 | Design System Consistency | Cross-page component usage |
+| 10 | Final Validation | Overall quality assessment |
+
+---
+
+## Final Output
+
+Save validation report to `{output_folder}/_progress/validation-report.md`
+
+---
+
+## AFTER COMPLETION
+
+1. Append a progress entry to `{output_folder}/_progress/00-design-log.md` under `## Progress`:
+   `### [date] — Validation: [N] pages audited, [results summary]`
+2. If issues found, suggest fixing them. If all pass, suggest next logical step from the adaptive dashboard
