### Requirements Coverage

| Requirement | Status    | Blocking Issue |
| ----------- | --------- | -------------- |
| ART-03      | SATISFIED | None — wizard Step 06 creates artist/, bible.md, discography.md, tracks/ |
| ART-04      | SATISFIED | None — 5 pre-built genre templates exist with section ordering and metatag placement |

### Anti-Patterns Found

None. No TODO/FIXME/placeholder comments found in any template files. All templates contain substantive content with no empty implementations. Line counts consistently use ranges (e.g., 4-8, 8-16) throughout.

### Human Verification Required

None required. All success criteria are verifiable programmatically via file content inspection.

### Gaps Summary

No gaps. All phase artifacts are present, substantive, and correctly wired.

- The wizard's Step 06 fully implements ART-03: creates the artist folder, bible.md (from template), discography.md (from template), and tracks/ subdirectory.
- All 5 genre templates (pop, rap, ballad, rock, electronic) are substantive files with frontmatter, Section Flow, Variations, and Notes sections.
- The electronic template explicitly uses Build-Drop structure with no verse-chorus content.
- The README index is a complete, browsable table with links to all 5 templates and a reference to format.md.
- STRUCTURE.md accurately reflects the full hierarchy including all Phase 2 and Phase 3 artifacts.
