From d1158feef4a4ac91e78bb56e35f6bf4a329d6795 Mon Sep 17 00:00:00 2001 From: Deborah Mangan Date: Mon, 3 Nov 2025 10:37:41 +1000 Subject: [PATCH] refactor: Replace try! with safe ModelContainer initialization fallbacks - Remove try! force operation that could crash on in-memory container failure - Implement cascading fallback strategy with 3 initialization attempts: 1. Persistent storage (normal operation) 2. In-memory storage with user warning 3. Ultra-minimal default container - Add containerInitializationFailed flag to track critical failures - Extract container creation into static helper methods for better error handling - Show user-friendly error dialog and graceful termination on total failure - Only use preconditionFailure as absolute last resort after all attempts fail Addresses AI code reviewer feedback about unsafe force operations.
