# Drawing Brief

Status: L2 V5 build-packet candidate.

The existing drawings in `drawings/` are reference-only planning evidence.
Future shop drawings must cite measured or reviewed CAD/DXF/design-table
authority.

## Required Future Drawings

| Drawing ID | Scope | Required Authority | Notes |
| --- | --- | --- | --- |
| DWG-001 | Doundounba shell body | CAD/design table from measured diameter basis and wall thickness | Include stave count, OD/ID/head-seat definition, and tolerance. |
| DWG-002 | Sangban shell body | CAD/design table from measured diameter basis and wall thickness | Same datum scheme as doundounba. |
| DWG-003 | Kenkeni shell body | CAD/design table from measured diameter basis and wall thickness | Same datum scheme as doundounba. |
| DWG-004 | Generic stave profile | CAD/DXF/design table | Include bevel, length, width, thickness, sanding allowance, and grain direction. |
| DWG-005 | Head ring and bearing edge | Measured head-seat/ring offset data | Include ring stock, wrap thickness, clearances, and edge radius. |
| DWG-006 | Rope path and optional bell mount | Fit mockup and reviewed placement notes | Show lacing path, diamonds, strap/bell clearances, and snag points. |
| DWG-007 | Constant-angle stave jig | Reviewed CAD/DXF | Release only after chosen stave count and stock dimensions are final. |

## Drawing Rules

- Do not dimension from photos or scans without recording the measurement
  method and uncertainty.
- Use CAD/DXF/design-table or measured-template rows as fabrication authority.
- Mark any SVG/PDF/PNG preview as `derived_preview` unless it has a controlling
  authority row.
- Include units, revision date, datum assumptions, and unresolved gates on every
  future shop drawing.
