EduManager - Regras Globais e Escopo

🚀 Escopo do Projeto

EduManager é um Sistema de Gestão Escolar completo, focado em alta performance, usabilidade premium e automação de processos administrativos e acadêmicos.

🛠️ Stack Tecnológica

• Frontend/Backend: Remix (React)
• Banco de Dados: PostgreSQL (100% Local/Self-Hosted)
• Storage Architecture: 100% Self-Hosted (MinIO) - Decoupled from Supabase Cloud.
• Image Serving: All images are served via a backend proxy route (/storage/:bucket/:key) to ensure cross-origin compatibility and security.
• Synchronization: High-performance local API for bank reconciliation (Asaas).
• Orquestração e CI/CD: Portainer (Docker) com GitHub Actions via Self-Hosted Runner (Oracle ARM64 nativo) e Watchtower.
• Production Entry Point: All production deployments MUST use server.selfhosted.js renamed/copied as server.js in the Docker containers to ensure full local feature availability.

⚠️ Regras de Negócio Críticas (MANDATÓRIO)

[!IMPORTANT] Migração de Dados (Legado 'schoodat'): Ao realizar a migração completa dos dados do sistema legado 'schoodat' para o nosso banco de dados local Postgres, é terminantemente proibido alterar, resetar ou re-hashear as senhas existentes. As credenciais devem ser mantidas exatamente como estão para garantir que o acesso dos usuários não seja interrompido.

📜 Padrões de Desenvolvimento

1. Design System: Estética Premium, Dark Mode por padrão (ou glassmorphism), micro-animações e ausência de placeholders.
2. Segurança: Todas as rotas sensíveis devem validar o token JWT local (via secrets do ambiente). Proibido usar Supabase SDK para lógica de autenticação ou sincronização no frontend.
3. Resiliência: Tratamento rigoroso de erros em chamadas de API de terceiros (Asaas, Evolution API).
4. Upload de Arquivos: Proibido o uso de Base64 para envio de novos arquivos ao servidor. Use obrigatoriamente FormData e envie o objeto File/Blob para as rotas de API que integram com o MinIO.
5. Build & Deploy Stability: O pipeline de deploy deve obrigatoriamente utilizar runs-on: self-hosted e compilar apenas a plataforma linux/arm64 (sem emulação QEMU). A atualização da stack em produção deve ser automatizada via container transiente do Watchtower.
6. Express Compatibility: Avoid using raw /* wildcards in Express 5 routes; use Regex paths (/^\/route\/(.+)$/) for compatibility with path-to-regexp v8.
7. Frontend Independence: NEVER import files from services/ or server.js directly into React components to prevent Node.js/SDK leakage (causes White Screen). Physical isolation is enforced: backend-only services (like MinIO/S3 storage) MUST stay outside the src/ directory in Vite/React projects. Use helpers.ts for UI logic and standard fetch for API calls.
8. Login Persistence: Administrative sessions are persisted via localStorage ('edumanager_session'). The main entry point MUST validate the session on mount to ensure UX continuity.
9. Real-time & Sync: In self-hosted environments, use Intelligent Polling (30s) to synchronize notifications and critical data between Portal and Manager, as standard Supabase Realtime is disabled.
10. Justification Logic: Attendance justifications MUST include fromStudentId in notification metadata and support both arquivo and arquivo_base64 keys for attachment compatibility. Notifications SHOULD include the motive text in the message field (JSON format: {text, motivo}) to allow previews in the manager bell.
11. Modal Standards: System modals should utilize bg-transparent (no background darkening or blur) with shadow-2xl for depth, ensuring a clean and float-like aesthetic.
12. Messages Automation: Preventive reminders and overdue settings MUST be managed within their respective template modals (contextual logic), with independent manual triggers for each phase (Overdue vs. Upcoming).
13. Grading & Evaluation Standards: Assessments are categorized as exam (violet/violet labels) or activity (sky/blue labels). The report card (Boletim) MUST support multiple evaluations per period, showing the individual breakdown (name and value). The module MUST be named "Atividades e Provas" for clarity.
14. Asaas Safety: All financial generation forms MUST implement a loading state (isCreating) to disable submit buttons and prevent duplicate charges.
15. Retake Policy: Students ARE allowed to retake activities and exams. The system MUST delete the previous submission and overwrite the grade in school_data.json to ensure only the latest attempt is valid.
16. Financial Categories: The system supports categories: monthly (Mensalidade), registration (Matrícula), handout (Apostila), and others (Outros). Automated forms must map references (Cursos -> monthly, Registration -> registration, Handout -> handout).
17. Modal Floating Principle: All system modals must avoid backdrop-blur and background overlays. Use bg-transparent for the fixed container and bg-white (solid) for the modal box, ensuring contrast via large soft shadows (shadow-2xl or equivalent).
18. Automated Messaging (Cron Jobs): The system uses node-cron for independent message scheduling (Preventive vs. Overdue). Overdue logic MUST implement safety checks using overdue_warnings_count and last_overdue_warning_at to avoid spamming the student. Immediate webhook triggers for PAYMENT_OVERDUE are disabled in favor of scheduled routines.
19. Numerical Data Integrity: When retrieving data from PostgreSQL NUMERIC or DECIMAL columns, values MUST be explicitly cast to Number() in the backend before being sent to the frontend to prevent crashes when using .toFixed() in React.
