## 1. Product Identity

**Gatkul EduOS** (short: **EduOS**) is an institutional operating system for Indian schools. It is designed to connect school administration, teachers, students, parents, transport staff, attendance, documents, learning workflows, communication, governed AI assistance, fees, and analytics in one secure school platform.

**Primary theme:** Connect · Grow · Evolve

| Beat | Meaning |
|------|---------|
| **Connect** | One institutional graph where leadership, faculty, guardians, and learners share governed truth — rumor drift fades when announcements, grades, and operational signals use one channel |
| **Grow** | Digital technology becomes discipline — structured projects, media literacy, assistive tools with guardrails, feedback loops that build learning awareness |
| **Evolve** | Schools look beyond term marks — alumni pathways, service learning, civics literacy, agile thinkers who adapt without losing values |

**Company:** Gatkul Automotives Private Limited  
**Product family:** Gatkul Apps  
**SaaS platform name:** Gatkul adhyOS (institutional subscription billing)  
**Marketing domain:** [gatkul.app](https://gatkul.app)  
**Contact:** hello@gatkul.app

### What EduOS Is

- A **complete school operating system** — administration, academics, communication, documents, attendance, fees, transport, parent engagement, and AI-assisted workflows in one fabric
- **India-ready** — Maharashtra State Board alignment, regional languages (English `en`, Hindi `hi`, Marathi `mr`), board-aware syllabus and AI retrieval taxonomy
- **Institution-trustworthy** — per-school tenant isolation, audit trails, role-based access, recovery-oriented operations, human-in-the-loop AI governance
- **Multi-surface** — web ERP for operators, Capacitor mobile shells for daily engagement, Garuda AI for role-specific assistance
- **Deployable** — SaaS (adhyOS) or on-premise Docker stack for schools that require full data ownership

### What EduOS Is Not

- **Not** "just an ERP" — it includes real-time communication, engagement loops, transport, and governed AI
- **Not** a generic messaging or social app — channels are school-scoped, moderated, and role-bound
- **Not** a homework-cheating or answer-completion service — Garuda uses Socratic guidance for students
- **Not** a notification-spam engine — every push must earn its place (see §8)
- **Not** the marketing website — `website/` is product storytelling; `apps/web` + `apps/api` are the live school runtime

### Surface Responsibilities

| Path | Role | Serves |
|------|------|--------|
| `apps/web` | School ERP frontend | Administrators, teachers, parents, students, tech-admin — dashboards, forms, chat, mobile WebView shells |
| `apps/api` | School platform backend | REST API, WebSocket messaging, notifications, AI, billing, control-plane, multi-tenant data |
| `website` | Marketing & registration | Product narrative, EduOS hero/vision, help center, school registration checkout — **no school tenant data** |

**Do not conflate** `website/` EduOS narrative components (`EduOSHero`, `InstitutionGraph`, narrative rail) with live RAG APIs in `apps/api/src/ai-assistant/`.

## 3. Technical Architecture

### Stack

| Layer | Technology |
|-------|------------|
| Frontend | Next.js 15, React 18/19, Tailwind CSS, Zustand, Socket.IO client, TypeScript |
| Mobile | Capacitor (Android + iOS) — student, teacher, admin flavor builds |
| Backend | NestJS, TypeORM, Passport.js + JWT, Bull queues, TypeScript |
| Database | PostgreSQL 16 (system of record) |
| Cache / realtime | Redis 7 (sessions, Socket.IO adapter, job queues) |
| Push | Firebase Admin (FCM — Android + iOS), Web Push (VAPID) |
| Email | Transactional outbox → SMTP / SES |
| Files | Local encrypted storage, SHA256 integrity, MIME validation |
| Auth | Argon2id hashing, JWT access (15m) + refresh (7d) with rotation |

### Request Flow

```
Browser / Mobile WebView (apps/web)
    ↓ HTTPS REST + WSS
Nginx (reverse proxy, TLS, rate limiting)
    ↓
NestJS API + Socket.IO Gateway (apps/api)
    ↓
PostgreSQL 16 + Redis 7 + File Storage
```

### Notification Pipeline

```
Domain event
  → notification_outbox (PostgreSQL)
  → NOTIFICATIONS dispatcher queue (Bull)
  → channel routing:
      PUSH → push-android (FCM) + push-web (VAPID)  [parallel fan-out]
      EMAIL → email queue
      SMS → future channel
  → exponential backoff on failure
  → FCM batch sends (500 messages/batch)
```

Outbox statuses: `PENDING` · `SENT` · `FAILED` · `SKIPPED`

### Locales

UI and API user preferences support `en`, `hi`, `mr`. Marketing narrative also provides Hindi overlays for EduOS story surfaces.

## 5. User Roles and Permissions

Canonical enum: `apps/api/src/common/enums/user-role.enum.ts`

| Role | Code | Typical user | Permission scope |
|------|------|--------------|------------------|
| Platform tech admin | `TECH_ADMIN` | Gatkul operator | Multi-school control plane, recovery, snapshots, provisioning |
| School administrator | `ADMIN` | Principal, office head | Full school config: users, academics, fees, notices, audit |
| Teacher | `TEACHER` | Faculty | Assigned classes: attendance, homework, exams, lesson plans, parent messaging |
| Parent | `PARENT` | Guardian | Linked children only: attendance, homework, fees, messaging, updates |
| Student | `STUDENT` | Student with login | Own dashboard, homework, study tools, Garuda (Socratic, syllabus-bound) |
| Young student | `STUDENT_READONLY` | Primary student | Read-only experience, tighter AI guardrails |
| Bus driver | `DRIVER` | Transport staff | Transport routes and boarding only — no academic or fee access |
| Investor | `INVESTOR` | External stakeholder | Read-only investor portal |

### Authentication Model

- Login format: `username@schoolcode` (e.g. `admin@demoschool`)
- Each school is a **tenant** with isolated PostgreSQL data scoped by `schoolId`
- JWT guards (`JwtAuthGuard`) + role guards (`RolesGuard`) on protected endpoints
- Per-device session tracking with revocation support

### Authorization Principles for Agents

- Never describe cross-tenant data access as normal behavior
- Parents see only their linked children
- Teachers see only assigned classes/subjects
- Drivers see only transport scope
- Students cannot access admin or other students' records
- Garuda context is filtered by `ContextAccessPolicyService` per role

## 7. Connect · Grow · Evolve Narrative

Source: `website/src/content/eduosConnectGrowVision.ts`, `website/src/content/adhyos.ts`

**Vision headline:** Digital infrastructure for aware, advanced, agile citizens

**Narrative closing:** Onboarding is a pact with the future — principals gain posture, teachers gain time, parents gain clarity, students gain continuity.

**Marketing trust strip:** Tenant isolation · Audit-friendly workflows · Recovery-ready backups

**Hero positioning:** EduOS is the operating system for modern educational institutions — institution-scale, Mission Control visibility, governed AI, India-ready boards and regional languages.

---

## 8. Notification Philosophy and Safety Policy

EduOS notifications must **not** behave like generic app spam.

### Five Checks (all must pass)

1. **Relevance** — meaningful for this user's role?
2. **Specificity** — concrete enough to act on without opening the app?
3. **Timing** — right context and moment (respecting quiet hours)?
4. **Actionability** — helps school, student, teacher, or parent take a meaningful next step?
5. **Restraint** — can it be suppressed, batched, delayed, or summarized instead?

### Goal

Build positive educational habits:
- Attendance discipline
- Homework completion
- Exam preparation
- Parent awareness
- Teacher follow-through
- School participation
- Safety responsiveness (especially transport)

### Preferred Language

Clear, respectful, school-friendly. Avoid manipulative urgency unless genuinely urgent: transport safety, emergency notices, hard deadlines, attendance risk.

### Avoid

- Clickbait and fear-based manipulation
- Excessive or duplicate notifications
- Repeated reminders without new context
- Notifications after quiet hours
- Student performance exposed in push text
- Sensitive personal details on lock-screen notifications
- Generic "open the app" prompts with no substance

### Approved Examples

**Parent — Attendance**
Your child was marked present today at 9:12 AM. View today's school update.

**Parent — Homework**
Aarav has maths homework due tomorrow. 12 students have already submitted from Class 5A.

**Teacher — Workflow**
Class 7B attendance is still pending. It usually takes under 2 minutes to complete.

**Parent — Fee reminder**
Term fee payment is due on 15 July. Open EduOS to view the amount and payment options.

**Student — Exam preparation**
Science exam is in 3 days. Revision notes for Chapter 4 are ready.

**Teacher — Positive reinforcement**
Great progress: Class 6A reached 94% homework completion this week.

**Parent — School memory**
3 years ago today: your school celebrated Science Day. View the memory album.

**Transport — Safety**
Bus Route 4 is running 12 minutes late. Estimated arrival at Green Park stop: 3:42 PM.

### Technical Safety Controls

- `notification_outbox` per-recipient rows with `schoolId` scoping
- FCM `channelId` for Android notification channels (e.g. `jijau_messages`, `jijau_announcements`)
- Multi-device fan-out with `all` / `primary` / `creator` scope options
- Failed delivery retry with exponential backoff (`processAfter`)
- Email as alternate channel for non-urgent institutional comms

## 10. Indian School Context

### Education Board
- Primary alignment: **Maharashtra State Board**
- RAG taxonomy normalizes board labels for retrieval (`MAHARASHTRA_BOARD` in `rag-taxonomy`)
- Syllabus subjects include: English, Mathematics, Science, History, Geography, Marathi, Hindi, Civics, Economics, Physics, Chemistry, Biology

### Languages
- Platform UI: English, Hindi (`hi`), Marathi (`mr`)
- Marketing narrative: Hindi overlays available (`website/src/i18n/narrativeLocales/hi.all.ts`)
- Agents generating copy should prefer respectful, school-appropriate Indian English; offer Hindi/Marathi when audience is regional

### Fee Cycles
- Term-based fee structures (quarterly/annual patterns common)
- Fee reminders should include due date and payment path — never shame or threaten
- Payment via school EduOS portal or school office
- Receipts issued under Gatkul adhyOS SaaS subscription model for platform billing

### Transport Safety
- `DRIVER` role is transport-scoped only
- Parent alerts for delays, boarding events, route changes
- Transport notifications are **high-priority legitimate urgency** — exempt from "avoid urgency" guidance when safety-relevant
- Never expose unrelated student details in transport push text

### Rural and Semi-Urban Readiness
- Low-friction flows, minimal training requirement
- Modest hardware deployment (Docker on 4GB RAM Ubuntu server documented)
- Offline-tolerant planner sync patterns on client
- Push notifications as primary parent engagement channel where SMS cost is a concern

---

## 11. Real-Time Messaging

- Socket.IO gateway with Redis adapter for horizontal scaling
- Conversation types: direct (parent↔teacher, teacher↔admin), group (class, subject), school-wide announcements
- Features: threading, reactions, read receipts, file attachments, soft delete with moderation
