 - [Phase 02-layout-and-brand-identity]: Gradient background uses palette.saving/bill/investment light shades at 135deg for subtle tinted-paper feel on auth screens
 - [Phase 02-layout-and-brand-identity]: Alert destructive replaces plain error <p> — semantic role=alert improves a11y and enables test assertions
 - [Phase 02-layout-and-brand-identity]: Gradient wordmark uses inline oklch style, active state overrides sidebar-primary, SidebarTrigger in SidebarInset header
+- [Phase 03-interaction-quality-and-completeness]: onSaveSuccess/onSaveError are optional callbacks — callers opt in to row-flash behavior in downstream plans
+- [Phase 03-interaction-quality-and-completeness]: Budget Edit spinner deferred — no BudgetEdit form component exists in codebase yet
+- [Phase 03-interaction-quality-and-completeness]: Mock useBudgets hook in DashboardPage tests to control loading state directly
+- [Phase 03-interaction-quality-and-completeness]: BillsTracker renders a full Card component — tests render it standalone, not inside a <tr>
