+# Ballistic Builder ( The Armory?) Backend  
+### Internal Engine for the Shadow System Armory?
+
+The Ballistic Backend is the operational backbone behind the Shadown System Armory and its admin tools. It ingests merchant feeds, normalizes product data, manages categories, synchronizes prices, and powers the compatibility, pricing, and product logic behind the consumer-facing Builder.
+
+It’s built for reliability, longevity, and clean extensibility — the kind of foundation you want when scaling from a small beta to a fully public platform.
+
+---
+
+## What This Backend Does
+
+### **Merchant Feed Ingestion**
+- Pulls AvantLink feeds (CSV or TSV)
+- Automatically detects delimiters
+- Normalizes raw merchant fields
+- Creates or updates product records
+- Upserts price and stock offers
+- Tracks first-seen / last-seen timestamps
+- Safely handles malformed or incomplete rows  
+- Ensures repeat imports never duplicate offers
+
+### **Category Mapping Engine**
+- Identifies every unique raw category coming from each merchant feed  
+- Exposes *unmapped* categories in the admin UI  
+- Allows you to assign:  
+  - Part Role  
+  - Product Configuration (Stripped, Complete, Kit, etc.)
+- Applies mappings automatically on future imports  
+- Respects manual overrides such as `platform_locked`
+
+### **Builder Support**
+The frontend Builder depends on this backend for:
+
+- Loading parts grouped by role  
+- Offering compatible options  
+- Calculating build cost  
+- Comparing offers across merchants  
+- Providing product metadata, imagery, and offer data  
+
+**Future expansions include:** price history, compatibility engine, build exports, public build pages, multi-merchant aggregation, and automated anomaly detection.
+
+---
+
+## Tech Stack
+
+- **Spring Boot 3.x**  
+- **Java 17**  
+- **PostgreSQL**  
+- **Hibernate (JPA)**  
+- **HikariCP**  
+- **Apache Commons CSV**  
+- **Maven**  
+- **REST API**
+
+---
+
+## Local Development
+
+### Requirements
+- Java 17 or newer  
+- PostgreSQL running locally  
+- Port 8080 open (default backend port)
+
+### Run Development Server
+
+```bash

+# Ballistic Import Pipeline  
+A high-level overview of how merchant data flows through the Spring ETL system.
+
+---
+
+## Purpose
+
+This document explains how the Ballistic backend:
+
+1. Fetches merchant product feeds (CSV/TSV)
+2. Normalizes raw data into structured entities  
+3. Updates products and offers in an idempotent way  
+4. Supports two sync modes:
+   - Full Import
+   - Offer-Only Sync

+
+# 2. Full Import Explained
+
+Triggered by:
+
+```
+POST /admin/imports/{merchantId}
+```
+
+### Step 1 — Load merchant  
+Using `merchantRepository.findById()`.
+
+### Step 2 — Parse feed rows  
+`readFeedRowsForMerchant()`:
+- Auto-detects delimiter (`\t`, `,`, `;`)
+- Validates required headers
+- Parses each row into `MerchantFeedRow`
+
+### Step 3 — Process each row
+
+For each parsed row:
+
+#### a. resolveBrand()
+- Finds or creates brand
+- Defaults to “Aero Precision” if missing
+
+#### b. upsertProduct()
+Dedupes by:
+
+1. Brand + MPN  
+2. Brand + UPC (currently SKU placeholder)  
+
+If no match → create new product.
+
+Then applies:
+- Name + slug
+- Descriptions
+- Images
+- MPN/identifiers
+- Platform inference
+- Category mapping
+- Part role inference
+
+#### c. upsertOfferFromRow()
+Creates or updates a ProductOffer:
+- Prices
+- Stock
+- Buy URL
+- lastSeenAt
+- firstSeenAt when newly created
+
+Idempotent — does not duplicate offers.
+
+---
+
+# 3. Offer-Only Sync
+
+Triggered by:
+
+```
+POST /admin/imports/{merchantId}/offers-only
+```
+
+Does NOT:
+- Create products  
+- Update product fields  
+
+It only updates:
+- price
+- originalPrice
+- inStock
+- buyUrl
+- lastSeenAt
+
+If the offer does not exist, it is skipped.
+
+---
+
+# 4. Auto-Detecting CSV/TSV Parser
+
+The parser:
+
+- Attempts multiple delimiters
+- Validates headers
+- Handles malformed or short rows
+- Never throws on missing columns
+- Returns clean MerchantFeedRow objects
+
+Designed for messy merchant feeds.
+
+---
+
+# 5. Entities Updated During Import
+
+### Product
+- name  
+- slug  
+- short/long description  
+- main image  
+- mpn  
+- upc (future)  
+- platform  
+- rawCategoryKey  
+- partRole  
+
+### ProductOffer
+- merchant
+- product
+- avantlinkProductId (SKU placeholder)
+- price
+- originalPrice
+- inStock
+- buyUrl
+- lastSeenAt
+- firstSeenAt
+
+### Merchant
+- lastFullImportAt
+- lastOfferSyncAt
+
+---
+
+# 6. Extension Points
+
+You can extend the import pipeline in these areas:
+
+- Add per-merchant column mapping  
+- Add true UPC parsing  
+- Support multi-platform parts  
+- Improve partRole inference  
+- Implement global deduplication across merchants  
+
+---
+
+# 7. Quick Reference: Main Methods
+
+| Method | Purpose |
+|--------|---------|
+| importMerchantFeed | Full product + offer import |
+| readFeedRowsForMerchant | Detect delimiter + parse feed |
+| resolveBrand | Normalize brand names |
+| upsertProduct | Idempotent product write |
+| updateProductFromRow | Apply product fields |
+| upsertOfferFromRow | Idempotent offer write |
+| syncOffersOnly | Offer-only sync |
+| upsertOfferOnlyFromRow | Update existing offers |
+| detectCsvFormat | Auto-detect delimiter |
+| fetchFeedRows | Simpler parser for offers |
+
+---
+
+# 8. Summary
+
+The Ballistic importer is:
+
+- Robust against bad data  
+- Idempotent and safe  
+- Flexible for multiple merchants  
+- Extensible for long-term scaling  
+
+This pipeline powers the product catalog and offer data for the Ballistic ecosystem.
