- User, Project, TimeEntry JPA entities with SLF4J logging in services - Native SQL aggregate queries: per-day (weekly) and per-project (monthly) both using COALESCE(project_rate, user_rate) for cost calculation - ReportService parses ISO week/month strings, fills zero-day gaps, computes timeBudgetPct / costBudgetPct / breached per project - ProjectService piggybacks on aggregateAllByProject for budget status on GET /api/projects (no N+1) - GlobalExceptionHandler maps validation errors → 400 ProblemDetail, EntityNotFoundException → 404, IllegalArgumentException → 400 - Lombok on pom.xml (optional, used for @Getter/@Setter/@NoArgsConstructor) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
