 - [Pre-phase]: German-only UI for MVP; localization infrastructure (ARB + AppLocalizations) required from Phase 1 even with one locale
 - [Pre-phase]: riverpod_lint must be active before any feature code — catches ref.watch outside build() at analysis time
 - [Pre-phase]: drift_dev make-migrations workflow must be established in Phase 1 — recovery cost is data loss
+- [01-01]: Pinned drift/drift_dev to 2.31.0 for analyzer ^9.0.0 compatibility with riverpod_generator 4.0.3
+- [01-01]: Generated Riverpod 3 provider named themeProvider (not themeNotifierProvider) per new naming convention
