   - Revisar tokens declarados pero no usados para separar: reserva doctrinal
     intencional vs residuo de CSS legacy.
 
+Actualizacion Eidos auditoria Kimi 2026-05-16:
+
+- Hallazgos corregidos:
+  - `tabs-indicator.svelte` pasa de `onMount` a `$effect` con cleanup ligado
+    al `ref`. Nota: `onMount` no es incompatible con Svelte 5, pero `$effect`
+    encaja mejor aqui porque el observer depende del elemento enlazado.
+  - Icono `folder-root.svelte` exportado como `FolderRoot` y catalogado como
+    `folder-root` / `FolderRoot`; se elimina el falso `FolderProvider`.
+  - Comentario de `toggle.svelte` corregido: Eidos expone `<Toggle>`, no
+    `<Toggle.Provider>`.
+  - Helpers repetidos de `eidos/lib` centralizados en `utils.ts`:
+    `clonePlain`, `isPlainRecord`, `hasOwn`, `toKebab`.
+  - `isPlainRecord` queda unificado como objeto literal o null-prototype; no
+    acepta arrays ni instancias de clase.
+- Hallazgos evaluados pero no aplicados:
+  - `dialog.svelte` y `drawer.svelte` no necesitan `data-size` en el root:
+    sus props visuales viven en `Content`; `variant`/`direction` son headless
+    y ya los proyecta Soma/Morfo.
+  - `icon.svelte` mantiene `class` como prop DOM idiomatica; cambiar a
+    `className` seria menos natural en Svelte y no resuelve un bug real.
+  - `StyleBlockManager`, builder de recipes y action separada para Tabs
+    quedan como refactors posibles, no P0/P1.
+- Validacion:
+  - `npm run check` -> 0 errores, 0 warnings.
+  - `npx vitest run src/uix/eidos` -> 4 archivos, 56 tests OK.
+  - `npm run test` -> 233 archivos, 2270 tests OK.
