From 9c1ca2d076c4c729800f1da794f38d26edf2d186 Mon Sep 17 00:00:00 2001 From: Leo Dion Date: Fri, 23 Jan 2026 16:08:39 -0500 Subject: [PATCH 1/3] Add comprehensive data validation to Foundation types Implements validation for DataSourceMetadata, RestoreImageRecord, and ReviewEngagementThreshold to prevent runtime errors from invalid data. CloudKit record names are validated for ASCII compliance and length constraints, restore image hashes are validated for proper format, and environment configuration uses a type-safe wrapper with appropriate defaults.
