+### CL-095: 22500 `components/elements/index.js` hook-order hotfix (`MultiLinefield`)
+
+date: 2026-04-07
+author: Cline
+scope: `components/elements/index.js`
+type: change
+rationale: Fix runtime React warning caused by conditional hook execution path in `MultiLinefield` after dead-code cleanup.
+impact: No functional behavior change intended; resolves Rules of Hooks ordering warning by making label translation hook usage unconditional per render.
+status: completed
+
+Summary:
+
+- Root cause: `FieldsTranslations(props.label)` (which internally uses `useRouter`) was invoked within conditional render branches in `MultiLinefield`, causing hook order mismatch when branch conditions changed.
+- Fix: precomputed `translatedLabel` once in `MultiLinefield` render body and reused in both branches.
+- Kept EN/CY text resolution logic and rendered output unchanged.
+
+Validation:
+
+- `npx eslint components/elements/index.js` -> pass
+
+Follow-ups:
+
+- Continue bounded Phase 2 slices; when touching field components, prefer top-level computed hook-backed values reused across conditional branches.
