PragatiVeer v2 — Pagewise UI & API Specification Map

Document Type: Comprehensive Pagewise Architecture, Button-to-API Interaction, and UI Specification Map
Target Audience: Frontend Engineers, Full-Stack Developers, Product Managers, QA & DevOps
Last Verified: September 2026
Frontend Engine: Next.js 16 (App Router, React 19, TypeScript, TailwindCSS, Zustand)
Backend Engine: FastAPI (Python 3.11) + PostgreSQL 15 (PgBouncer) + Redis 7 + MinIO S3

1. Architectural & Network Request Flow

1.1 Client-to-Backend Network Pipeline

PragatiVeer v2 operates two primary communication paths between the Next.js frontend and the FastAPI backend:

graph LR
    Browser["Client Browser"] -->|1. Page Navigation| NextServer["Next.js 16 App Router (:3000)"]
    NextServer -->|2. Route Guard proxy.ts| Edge["Edge Cookie Evaluation"]
    Browser -->|3. /api/* Internal Calls| Rewrites["next.config.ts Rewrites"]
    Rewrites -->|http://backend:8000/api/*| FastAPI["FastAPI Backend (:8000)"]
    Browser -->|4. Direct NEXT_PUBLIC_API_URL| FastAPI
    FastAPI -->|Queries| PgBouncer["PgBouncer :5432"]
    PgBouncer --> DB[("PostgreSQL 15")]
    FastAPI -->|Cache & Tasks| Redis[("Redis 7")]
    FastAPI -->|S3 Uploads| MinIO[("MinIO S3 :9000")]

Proxy Middleware (src/proxy.ts): Evaluates auth_token cookie on all /dashboard/* and /admin/* routes.
- Non-authenticated visitors heading to /dashboard are redirected to /login.
- Non-admin visitors (token !== 'admin') heading to /admin are redirected to /login.
Reverse Proxy Rewrites (next.config.ts): Inside Docker, /api/:path* is automatically rewritten to http://backend:8000/api/:path*.
Direct Client Fetching: Certain client stores (e.g. cbtStore.ts and src/app/cbt/[examId]/page.tsx) use NEXT_PUBLIC_API_URL (default http://localhost:8000) for high-throughput examination requests.
Session Token Enforcement: localStorage.getItem("active_session_token") provides single-device session validation against /api/users/{id}/session.

5. Codebase Cleanup Audit & Phase 2 Roadmap

5.1 Cleaned & Removed Legacy Files

In accordance with production standards, all dead/legacy files, log dumps, and temporary development artifacts have been hard-deleted:

backend/fix.py, backend/fix_from_source.py, backend/fix_ions.py: One-time scripts for manual question text extraction and repair.
backend/seed_dpps.py, backend/seed_dpps_mock.py, backend/seed_dpps_real.py, backend/seed_from_dpps.py: Legacy seed scripts superseded by seed.py.
backend/pragativeer-prd.pdf, backend/test.pdf, backend/test2.pdf: Temporary test binaries.
backend/pragativeer.db: Abandoned SQLite file (PragatiVeer exclusively uses PostgreSQL).
backend/pdfs_to_parse/: 15.3 MB of raw PDFs removed (already extracted into admin_uploads/).
backend/pdf_parser.py: Unused stub file removed to prevent dead code clutter.
backend.log, backend_logs.txt, full_logs.txt: Obsolete runtime logs.
alter.sql, userlist.txt, CLAUDE.md: Temporary scratch and SQL debug files.
create_policies.py, fix_icons.py, generate_jee_json.py: One-time generation/migration scripts.

5.2 Preserved Academic & Testing JSON Assets

As required for manual verification, test runs, and format specifications, the following question datasets remain actively preserved in the codebase:

jee_advanced_full_90q.json: Comprehensive 90-question JEE Advanced sample dataset for exam testing.
neet_180_questions.json: Comprehensive 180-question NEET UG sample dataset for exam testing.
admin_json_samples.md: Official JSON schema specifications and samples for Admin question uploader.
neet_sample_questions.md: NEET sample question reference and validation format.
admin_uploads/: 4 Daily Practice Sheets (Biology, Chemistry, Mathematics, Physics Chapter 4 JSONs) seeded directly into the CBT engine.

5.3 Decoupled Dependencies (`requirements.txt`)

The following heavy external packages were removed from backend/requirements.txt:

openai==1.14.0: Decoupled to eliminate reliance on external LLM keys during initial rollout.
PyMuPDF==1.23.26: Decoupled to prevent native C-library compile overhead in production.

5.4 Production-Safe AI Modules

backend/llm.py: Cleanly stubbed with an async generator returning a friendly coming-soon notice.
backend/worker.py: Retains exclusively the active 5:00 AM IST Celery Beat daily study plan scheduler.
POST /api/admin/tests/upload: Saves PDF to MinIO and guides administrators to use /api/admin/tests/create_manual until Phase 2 is provisioned.
