+### CL-00Y: 22500 `components/elements/index.js` Phase 2 leaf renderer extraction (Rich multiline)
+
+date: 2026-04-07  
+author: Cline  
+scope: `components/elements/index.js`, `components/elements/fields/renderRichMultiline.js`  
+type: change  
+rationale: Continue the approved phased decomposition by extracting one low-risk leaf renderer (`RenderRichMultiline`) from the elements monolith while keeping existing field wiring and behavior intact.  
+impact: Refactor-only move of rich multiline renderer implementation; no route/API/auth/security changes and no intended EN/CY behavior change.  
+status: completed
+
+Summary:
+
+- Added `components/elements/fields/renderRichMultiline.js` containing the extracted `RenderRichMultiline` renderer.
+- Updated `components/elements/index.js` to import the extracted renderer and removed the inline duplicate implementation.
+- Kept `RichMultiLinefield` usage and props unchanged (same Redux Field component wiring and validation flow).
+
+Validation:
+
+- `npx eslint components/elements/index.js components/elements/fields/renderRichMultiline.js` -> pass
+
+Follow-ups:
+
+- Continue Phase 2 in bounded slices by extracting additional low-risk leaf renderers (e.g., `RenderMultiline` / `RenderTextfield`) with no behavior change.
