 ## Project Overview
 
 Filamenteka is a 3D printing filament inventory management system for tracking Bambu Lab filaments. It consists of:
-- **Frontend**: Next.js app with React, TypeScript, and Tailwind CSS (static export)
+- **Frontend**: Next.js app with React, TypeScript, and Tailwind CSS (static export to `/out`)
-- **Backend**: Node.js API server with PostgreSQL database
+- **Backend**: Node.js Express API server (`/api/server.js`) with PostgreSQL database
-- **Infrastructure**: AWS (Amplify for frontend, EC2 for API, RDS for database)
+- **Infrastructure**: AWS (CloudFront + S3 for frontend, EC2 for API, RDS for database)
+- **Repository**: `git.demirix.dev/dax/Filamenteka`
 
 ## Critical Rules
 
-- NEVER mention ANY author in commits. No author tags or attribution
+- NEVER mention ANY author in commits. No author tags or attribution of any kind
-- NEVER mention AI/assistant names anywhere
-- Keep commit messages clean and professional with NO attribution
 - Build for AMD64 Linux when deploying (development is on ARM macOS)
-- Always run security checks before commits
+- Always run security checks before commits (Husky pre-commit hook does this automatically)

+cd api && npm run dev    # Start API with nodemon (port 4000)
-npm run test:build       # Test if build succeeds
-./scripts/pre-commit.sh  # Runs security, build, and test checks (use before commits)
 
-# Database Migrations
+# Quality Gates
-npm run migrate          # Run pending migrations
+npm run security:check   # Credential leak detection
-npm run migrate:clear    # Clear migration history
+npm run test:build       # Verify build succeeds without deploying

+
+# Database
+npm run migrate          # Run pending migrations locally
+scripts/update-db-via-aws.sh  # Run migrations on production RDS via EC2
+
+# Deployment (auto via CI/CD on push to main, or manual)

+scripts/deploy-frontend.sh    # Manual frontend deploy to S3/CloudFront
 ```
 
 ## Architecture
 
-### Frontend Structure (Next.js App Router)
+### Frontend (Next.js App Router)
-- `/app` - Next.js 13+ app directory structure
+- `/app/page.tsx` — Public filament inventory table (home page)
-  - `/page.tsx` - Public filament inventory table
+- `/app/upadaj/` — Admin panel: login, `/dashboard` (filament CRUD), `/colors` (color management), `/requests` (customer color requests)
-  - `/upadaj` - Admin panel (password protected)
+- `/src/services/api.ts` — Axios instance with auth interceptors (auto token injection, 401/403 redirect)
-    - `/page.tsx` - Admin login
+- `/src/data/bambuLabColors.ts` — Primary color-to-hex mapping with gradient support (used by `ColorCell` component)
-    - `/dashboard/page.tsx` - Filament CRUD operations
+- `/src/data/bambuLabColorsComplete.ts` — Extended color database grouped by finish type (used by filters)
-    - `/colors/page.tsx` - Color management
-    - `/requests/page.tsx` - Customer color requests
-- `/src` - Source files
-  - `/components` - React components
-  - `/services/api.ts` - Axios instance with auth interceptors
-  - `/data` - Color definitions (bambuLabColors.ts, bambuLabColorsComplete.ts)
-  - `/types` - TypeScript type definitions
 
-### API Structure
+### API (`/api/server.js`)
-- `/api` - Node.js Express server (runs on EC2, port 80)
+Single-file Express server running on EC2 (port 80). All routes inline.
-  - `/server.js` - Main Express server with all routes inline
+- Endpoints: `/api/login`, `/api/filaments`, `/api/colors`, `/api/sale/bulk`, `/api/color-requests`
-  - Database: PostgreSQL on AWS RDS
+- Auth: JWT tokens with 24h expiry, single admin user (password from `ADMIN_PASSWORD` env var)
-  - Endpoints: `/api/login`, `/api/filaments`, `/api/colors`, `/api/sale/bulk`, `/api/color-requests`
 
-### Key Components
+### Database (PostgreSQL on RDS)
-- `FilamentTableV2` - Main inventory display with sorting/filtering
+Key schemas and constraints:
-- `SaleManager` - Bulk sale management interface
-- `ColorCell` - Smart color rendering with gradient support
-- `EnhancedFilters` - Advanced filtering system
-- `ColorRequestForm` - Customer color request form
-- `ColorRequestModal` - Modal for color requests
 
-### Data Models
+```
-
+filaments: id, tip (material), finish, boja (color), refill, spulna, kolicina, cena, sale_*
-#### Filament Schema (PostgreSQL)
+colors: id, name, hex, cena_refill (default 3499), cena_spulna (default 3999)
-```sql
+color_requests: id, color_name, message, contact_name, contact_phone, status
-filaments: {
-  id: UUID,
-  tip: VARCHAR(50),        # Material type (PLA, PETG, ABS)
-  finish: VARCHAR(50),     # Finish type (Basic, Matte, Silk)
-  boja: VARCHAR(100),      # Color name
-  refill: INTEGER,         # Refill spool count
-  spulna: INTEGER,         # Regular spool count
-  kolicina: INTEGER,       # Total quantity (refill + spulna)
-  cena: VARCHAR(50),       # Price
-  sale_active: BOOLEAN,    # Sale status
-  sale_percentage: INTEGER,# Sale discount
-  sale_end_date: TIMESTAMP # Sale expiry
-}
 ```
 
-#### Color Schema
+**Critical constraints:**
-```sql
+- `filaments.boja` → FK to `colors.name` (ON UPDATE CASCADE) — colors must exist before filaments reference them
-colors: {
+- `kolicina = refill + spulna` — enforced by check constraint
-  id: UUID,
+- Migrations in `/database/migrations/` with sequential numbering (currently up to `020_`)
-  name: VARCHAR(100),      # Color name (must match filament.boja)
-  hex: VARCHAR(7),         # Hex color code
-  cena_refill: INTEGER,    # Refill price (default: 3499)
-  cena_spulna: INTEGER     # Regular price (default: 3999)
-}
-```
 
-#### Color Requests Schema
+## Key Patterns
-```sql
-color_requests: {
-  id: UUID,
-  color_name: VARCHAR(255), # Requested color name
-  message: TEXT,            # Customer message

-## Deployment
+### Color Management (two-layer system)
+1. **Database `colors` table**: Defines valid color names + pricing. Must be populated first due to FK constraint.
+2. **Frontend `bambuLabColors.ts`**: Maps color names → hex codes for UI display. Supports solid (`hex: '#FF0000'`) and gradient (`hex: ['#HEX1', '#HEX2'], isGradient: true`).
+3. Color names must match exactly between `colors.name`, `filaments.boja`, and `bambuLabColors.ts` keys.
+4. The `ColorCell` component renders table row backgrounds from these mappings.
 
-### Frontend (AWS Amplify)
+### Adding New Colors
-- Automatic deployment on push to main branch
+1. Add to database `colors` table (via admin panel at `/upadaj/colors` or migration)
-- Build output: Static files in `/out` directory
+2. Add hex mapping to `src/data/bambuLabColors.ts`
-- Config: `amplify.yml`, `next.config.js` (output: 'export')
+3. Optionally add to `src/data/bambuLabColorsComplete.ts` finish groups
-- Security check runs during build (amplify.yml preBuild phase)
-
-### API Server (EC2)
-- Manual deployment via `scripts/deploy-api.sh` or `scripts/deploy-api-update.sh`
-- Server: `3.71.161.51`
-- Domain: `api.filamenteka.rs`
-- Service: `node-api` (systemd)
-- IMPORTANT: When deploying API, remember to build for AMD64 Linux (not ARM macOS)
-
-### Database (RDS PostgreSQL)
-- Host: `filamenteka.ci7fsdlbzmag.eu-central-1.rds.amazonaws.com`
-- User: `filamenteka_admin`
-- Database: `filamenteka`
-- Migrations in `/database/migrations/`
-- Schema in `/database/schema.sql`
-- Use `scripts/update-db-via-aws.sh` for running migrations on production
-
-## Important Patterns
 
 ### API Communication
-- All API calls use axios interceptors for auth (`src/services/api.ts`)
+- Service modules in `src/services/api.ts`: `authService`, `colorService`, `filamentService`, `colorRequestService`
-- Auth token stored in localStorage
+- Auth token stored in localStorage with 24h expiry
-- Automatic redirect on 401/403 in admin routes
+- Cache busting on filament fetches via timestamp query param
 
-### Color Management
+## CI/CD (Gitea Actions)
-- Colors defined in `src/data/bambuLabColors.ts` and `bambuLabColorsComplete.ts`
-- Automatic row coloring based on filament color
-- Special handling for gradient filaments
 
-### State Management
+`.gitea/workflows/deploy.yml` triggers on push to `main`. Auto-detects changes via `git diff HEAD~1`:
-- React hooks for local state
+- **Frontend changes** (anything outside `api/`): security check → tests → build → S3 deploy (3-tier cache: HTML no-cache, `_next/` immutable, rest 24h) → CloudFront invalidation
-- No global state management library
+- **API changes** (`api/` files): SSM command to EC2 to pull `server.js` from Gitea and restart `node-api` service
-- Data fetching in components with useEffect
+- Both run if both changed in a single push
 
-### Testing

-## Security Considerations
+## Pre-commit Hooks (Husky)
 
-- Admin routes protected by JWT authentication (24h expiry)
+`scripts/pre-commit.sh` runs automatically and blocks commits that fail:
-- Password hashing with bcrypt (for future multi-user support)
+1. Author mention check (blocks attribution)
-- SQL injection prevention via parameterized queries
+2. Security check (credential leaks)
-- Credential leak detection in pre-commit hooks (`scripts/security/security-check.js`)
+3. Build test (ensures compilation)
-- CORS configured to allow all origins (update for production hardening)
+4. Unit tests (`jest --passWithNoTests`)
-- Auth token interceptors handle 401/403 automatically
-- Pre-commit hook runs security checks, build tests, and unit tests
-
-## Database Operations
-
-When modifying the database:
-1. Create migration file in `/database/migrations/` with sequential numbering
-2. Test locally first
-3. Run migration on production:
-   - Use `scripts/update-db-via-aws.sh` for remote execution
-   - Or use `npm run migrate` for local/scripted execution
-4. Update corresponding TypeScript types in `/src/types/`
-
-Important database constraints:
-- `filaments.boja` has foreign key to `colors.name` (ON UPDATE CASCADE)
-- `filaments.kolicina` has check constraint: `kolicina = refill + spulna`
-- Always update `colors` table first before adding filaments with new colors
-
-## Terraform Infrastructure
-
-Infrastructure as Code in `/terraform/`:
-- VPC and networking setup
-- EC2 instance for API
-- RDS PostgreSQL database
-- Application Load Balancer
-- ECR for Docker images
-- Cloudflare DNS integration
