 ## Phase 1 — Consolidate Electron API Contract (Highest ROI)
 
-Status: ⚠️ Partially complete

 ### Problem
 `electronAPI` shape is duplicated across multiple files and can drift:

 ### Progress Check
 - Completed: shared contract module exists and is imported by preload and renderer ambient types.
-- Remaining: reduce overlapping data-shape duplication between shared API data interfaces and `src/renderer/store/appStore.ts` interfaces.
+- Completed: overlapping data-shape duplication was removed by sourcing store data interfaces from shared contract types.
 
 ### Acceptance Criteria
 - Single source of truth for `electronAPI` contract shape.
