Merge remote-tracking branch 'origin/dev' into feature/inam-platform-core-setup

- saas_provisioning_inbox with row-lock idempotency (exactly-once)
- SAAS_PIM_MODULE_SECRET exclusively — no generic-secret fallback
- Owner gate requires is_owner===true AND role_code===TENANT_OWNER (both)
- event_id required on /api/internal/events; missing or bad version → 422
- Unsupported event types → 422, never marked PROCESSED
- SSO role loading scoped through Role.tenant_id (cross-tenant safe)
- Migration: single named unique index on event_id (no duplicate inline)
- Soft deprovision preserves all PIM business data
- 23 live receiver tests + 11 unit tests, 0 failures
- Migration up/down verified clean
- PENDING: real SaaS outbox delivery + one-time SSO (ecosystem test)

+# 🏢 Core Multi-Tenant Architecture & Data Isolation Manual
+
+## 1. Executive Summary
+The PIM platform is designed as an Enterprise Multi-Tenant Software-as-a-Service (SaaS) application. It enforces strict logical isolation across tenants while sharing a unified application and database instance, maximizing resource efficiency, maintainability, and scalability.
+
+---
+
+## 2. Multi-Tenant Topology & Request Context Lifecycle

+```
+
+---
+
+## 3. Core Multi-Tenant Tenets & Invariants
+
+1. **Context Guarantee**: Every authenticated request populates `req.context`:
+   ```javascript
+   req.context = {
+     tenantId: 19,
+     userId: "3c847d01-e23a-4a22-9218-192a514d2847",
+     roleIds: ["role-tenant-admin-uuid"],
+     userType: "tenant", // 'platform' or 'tenant'
+     isImpersonating: false
+   };
+   ```
+2. **Repository Layer Scoping**: All Sequelize queries MUST include `where: { tenant_id: req.context.tenantId }` (unless executed by a platform administrator in global management view).
+3. **Tenant Provisioning Lifecycle**:
+   - Provisioning a new tenant creates:
+     - The `tenants` record.
+     - Default system roles (`TENANT_ADMIN`, `CATALOG_MANAGER`, `VIEWER`).
+     - Default permission bindings for all available `permission_nodes`.
+     - An initial root administrative user.
+     - Default taxonomy seeds (base units of measure, default attribute groups).

+# 🔐 Authentication & User Identity Management
+
+## 1. Overview
+The Authentication Subsystem provides JWT-based session management, password hashing via bcrypt (10 rounds), token refresh rotations, and multi-tier user classification (`platform` vs `tenant`).
+
+---
+
+## 2. User Types & Security Realms
+
+| User Type | Scope | Access Capabilities | Impersonation Allowed |
+| :--- | :--- | :--- | :--- |
+| **`platform`** | Global SaaS Operator | Full cross-tenant access, tenant provisioning, system nodes management, global billing and quotas | **YES** (via `x-impersonated-tenant-id`) |
+| **`tenant`** | Specific Workspace | Restricted strictly to records where `tenant_id === user.tenant_id`. Governed by assigned RBAC roles | **NO** |
+
+---
+
+## 3. JWT Payload Structure & Token Lifecycle
+
+### Token Structure
+```json
+{
+  "user_id": "3c847d01-e23a-4a22-9218-192a514d2847",
+  "email": "admin@maskantech.com",
+  "first_name": "Inam",
+  "last_name": "Admin",
+  "tenant_id": 19,
+  "user_type": "tenant",
+  "role_ids": ["fd9c2e97-9576-437d-aae9-939327efaf7e"],
+  "iat": 1787123456,
+  "exp": 1787209856
+}
+```
+
+### Security Workflows
+1. **Login (`POST /api/v1/auth/login`)**:
+   - Validates email and bcrypt password hash.
+   - Verifies `status === 'active'`.
+   - Eager-loads assigned `roles` and extracts `role_ids`.
+   - Returns Access Token (JWT) and User Profile payload.
+2. **Password Updates**:
+   - Requires previous password verification.
+   - Enforces minimum 8-character complexity with letter, number, and special character requirements.
+3. **Session Revocation**:
+   - Changing a user's status to `inactive` or deleting a user immediately halts subsequent requests as token validation checks against active DB records on critical operations.

+# 🛡️ RBAC Permissions Matrix & Security Engine
+
+## 1. Overview
+The Role-Based Access Control (RBAC) engine enforces fine-grained authorization across all platform resources. It decouples functional permission definitions (**Permission Nodes**) from business identities (**Roles**), allowing dynamic, tenant-level customization of user access privileges.
+
+---
+
+## 2. Permission Action Matrix (7-Point Granularity)
+
+Every permission node in the system supports 7 distinct operational flags:
+
+```mermaid
+graph LR
+    Node[Permission Node e.g. 'products'] --> View[can_view: Read & List]
+    Node --> Create[can_create: POST New]
+    Node --> Edit[can_edit: PUT/PATCH]
+    Node --> Delete[can_delete: Soft Delete]
+    Node --> Alter[can_alter: Schema/Publish]
+    Node --> Import[can_import: Batch Import]
+    Node --> Export[can_export: CSV/JSON Export]
+```
+

+| :--- | :--- | :--- | :--- |
+| **Products** | `products` | Product Catalog Management | Core SKU and product entity lifecycle management |
+| **Variants** | `variants` | Product Variants Management | Variant matrix generation and child SKU overrides |
+| **Families** | `families` | Product Families (Catalogs) | Catalog blueprints, variant axes, and asset rules |
+| **Categories** | `categories` | Categories Taxonomy | Hierarchical taxonomy tree and category assignments |
+| **Attributes** | `attributes` | Attribute Management | Attribute definitions, sets, and attribute groups |
+| **Brands** | `brands` | Brand Management | Brand registry and allowed brand constraints |
+| **Units** | `units` | Units of Measure (UOM) | Unit registry and conversion factors |
+| **Media (DAM)** | `assets` | Digital Asset Management | Media library uploads, asset types, and asset families |
+| **Channels** | `channels` | Channel Syndication | Channel endpoints, transformations, and feeds |
+| **Users & Roles** | `users` | User & RBAC Management | User provisioning, custom roles, and permission assignments |
+| **Audit Logs** | `audit_logs` | Security & Compliance Logs | Read-only audit trail inspection |
+| **Settings** | `settings` | Tenant Settings | Theme, white-labeling, and integration configurations |

+- `PUT` / `PATCH` $\rightarrow$ `can_edit`
+- `DELETE` $\rightarrow$ `can_delete`

+# 📜 Audit Logging, Security Interceptors & Compliance
+
+## 1. Overview
+The Audit Logging system provides an immutable, append-only historical record of all state-mutating actions across the PIM platform. It guarantees enterprise compliance (SOC 2, ISO 27001, GDPR) by recording *who* performed *what* action on *which* entity, along with chronological before-and-after JSON snapshots, IP addresses, and user-agent metadata.

+

+
+## 4. Compliance & Security Guarantees
+1. **Append-Only Immutability**: `audit_logs` has NO `update` or `delete` API endpoints. Once an audit record is written, it cannot be modified or truncated through standard application routes.
+2. **Tenant Scoping**: Audit log queries are strictly isolated to `tenant_id = req.context.tenantId`.
+3. **Session Context Association**: Every audit record links the originating authenticated JWT user ID and client network location.

+## 1. What is a Tenant? (The Apartment Analogy)
+
+Imagine this software is a **giant cloud apartment building**:
+
+```
+                       ┌─────────────────────────────────────────┐
+                       │          OUR PIM CLOUD SERVER           │

+│   (Nike Workspace)    │       │   (Apple Workspace)   │       │   (Sony Workspace)    │
+│                       │       │                       │       │                       │

+└───────────────────────┘       └───────────────────────┘       └───────────────────────┘
+```
+
+- **Tenant Isolation**: Every database table has a `tenant_id` column. When Nike logs in, their queries automatically execute with `WHERE tenant_id = 19`. It is physically impossible for Nike to see Apple's products or staff.
+
+---
+
+## 2. End-to-End Tenant Creation Lifecycle
+
+When a new client signs up (or a Platform SuperAdmin clicks **"Create New Tenant"**), the backend executes an automated **6-step provisioning pipeline** inside a single safe transaction:
+
+```mermaid
+sequenceDiagram
+    autonumber
+    actor Admin as Platform SuperAdmin
+    participant API as POST /api/v1/platform/tenants
+    participant DB as PostgreSQL Database
+    participant Seed as Auto-Provisioning Engine
+    participant Email as Notification Engine
+
+    Admin->>API: Submit Tenant Form (Name: "Acme Corp", Admin Email: "boss@acme.com")
+    
+    rect rgb(240, 248, 255)

+    end
+
+    API->>Email: Send Welcome Email & Password Setup Link to boss@acme.com
+    API-->>Admin: HTTP 201 Created (Tenant 25 Ready & Fully Operational)
+```
+
+---
+
+## 3. The RBAC Security Architecture
+
+RBAC (Role-Based Access Control) decouples **People** from **Permissions** using a 3-layer hierarchy:
+
+```
+┌───────────────────────────┐
+│         1. USERS          │   physical people who log in (Alice, Bob, Charlie)
+└─────────────┬─────────────┘
+              │  assigned to (via user_roles)
+              ▼
+┌───────────────────────────┐
+│         2. ROLES          │  job badges (Tenant Admin, Photographer, Pricing Specialist)
+└─────────────┬─────────────┘
+              │  contains (via role_permissions)
+              ▼
+┌───────────────────────────┐
+│   3. PERMISSION NODES     │  system modules (Products, Media DAM, Channels, Users)
+└───────────────────────────┘
+```
+
+---
+
+## 4. The 7 Permission Keys for Every Module
+
+For **every single module** in the system, there are **7 granular action switches**:
+
+```mermaid
+graph TD
+    Module["🚪 System Module (e.g. Products)"] --> K1["👀 can_view: Search, browse, and view details"]
+    Module --> K2["➕ can_create: Click 'New Product' and save drafts"]
+    Module --> K3["✏️ can_edit: Modify descriptions, prices, specs"]
+    Module --> K4["🗑️ can_delete: Soft-delete or archive records"]
+    Module --> K5["🚀 can_alter: Publish products or alter schema"]
+    Module --> K6["📥 can_import: Bulk import CSV / Excel files"]
+    Module --> K7["📤 can_export: Download data to Excel / JSON"]
+```
+
+### Complete System Modules Registry:
+| Module Code | Module Name | What It Controls |
+| :--- | :--- | :--- |
+| `products` | Product Catalog | Master product SKUs, prices, stock, and descriptions |
+| `variants` | Product Variants | Matrix generator, color/size axes, and child SKU overrides |
+| `families` | Product Families | Family blueprints, required attribute sets, and asset rules |
+| `categories` | Categories | Hierarchical taxonomy tree and category assignments |
+| `attributes` | Attributes & Sets | Dynamic specs, dropdown options, and attribute sets |
+| `brands` | Brands | Manufacturer brands and allowed brand rules |
+| `units` | Units of Measure | Measurement units (kg, pcs, cm) and conversion factors |
+| `assets` | Digital Assets (DAM) | Image uploads, document attachments, and asset types |
+| `channels` | Channels | Shopify, Amazon, and Custom CSV export integrations |
+| `users` | Users & Roles | Inviting staff, creating roles, and assigning permissions |
+| `audit_logs` | Audit Logs | Inspecting who changed what, timestamps, and IP history |
+| `settings` | System Settings | Theme customization, organization branding, and billing |
+
+---
+
+## 5. Real-World Role Configurations
+
+Here is how different job titles are configured using the 7-action matrix:
+
+### Role 1: "Junior Catalog Editor" (Intern)
+- `products`: `can_view` ✅, `can_create` ✅, `can_edit` ✅, `can_delete` ❌, `can_alter` ❌, `can_export` ❌
+- `assets`: `can_view` ✅, `can_create` ✅
+- `users` & `settings`: All ❌ (Cannot view or change team members)
+
+### Role 2: "Photographer / Media Specialist"
+- `assets`: `can_view` ✅, `can_create` ✅, `can_edit` ✅, `can_delete` ✅
+- `products`: `can_view` ✅ (To attach images), `can_edit` ❌ (Cannot change prices or stock)
+
+### Role 3: "Catalog Supervisor / Brand Manager"
+- `products`: All 7 keys ✅ (Including `can_alter` to publish products to live sales channels)
+- `families` & `categories`: All 7 keys ✅
+
+---
+
+## 6. How the Security Guard (Middleware) Works at Runtime
+
+Whenever a user takes any action in the application, the security guard inspects the request in **under 2 milliseconds**:
+
+```
+[ User clicks "Delete Product" in Browser ]
+                     │
+                     ▼
+[ API Request: DELETE /api/v1/products/80c68220... ]
+                     │
+                     ▼
+┌─────────────────────────────────────────────────────────────┐
+│ 👮 SECURITY GUARD (permission.middleware.js)                │
+│                                                             │
+│ 1. Verify JWT Token ──► User ID 42 (Alice)                  │
+│ 2. Check User Type ──► Tenant User (tenant_id = 19)         │
+│ 3. Check Admin Role ──► Is Alice TENANT_ADMIN? (No)         │
+│ 4. Check Alice's Role ──► "Junior Catalog Editor"           │
+│ 5. Check 'products' node ──► Is `can_delete` TRUE?          │
+│                                                             │
+│       ❌ Result: `can_delete` is FALSE!                     │
+└──────────────────────────────┬──────────────────────────────┘
+                               │
+                               ▼
+        ┌──────────────────────────────────────────┐
+        │ ⛔ HTTP 403 Forbidden Response:          │
+        │ "Insufficient permissions for action:    │
+        │ delete on module: products"              │
+        └──────────────────────────────────────────┘
+```
+
+The database query **never runs**, the product is **never touched**, and an attempt log is written to `audit_logs`.
+
+---
+
+## 7. Platform SuperAdmin Impersonation (Support Mode)
+
+If a customer (e.g. Tenant 19) opens a support ticket saying *"My attribute dropdown is stuck"*:
+
+1. A **Platform SuperAdmin** does NOT need the customer's password.
+2. The SuperAdmin opens the Platform Admin dashboard and clicks **"Troubleshoot Tenant 19"**.
+3. The frontend sends the header:
+   `x-impersonated-tenant-id: 19`
+4. The backend context middleware detects this and temporarily scopes the session to Tenant 19 in **Audit-Tracked Support Mode**.
+5. All actions taken while impersonating are stamped with `isImpersonating: true` in the audit logs.
+
+---
+
+## 8. Database Visual Schema & Relationship Map
+
+```mermaid
+erDiagram
+    TENANTS ||--o{ USERS : "contains"
+    TENANTS ||--o{ ROLES : "owns custom"

+## 3. High-Level Core Subsystems & Dependency Hierarchy
+
+To construct a valid Product, the system depends on an immutable, layered dependency hierarchy:
+
+```
+[Layer 0: Multi-Tenant Foundation]
+   ├── Tenant Isolation (tenant_id scoping)
+   └── RBAC & Audit Trails (User Sessions, Permissions)
+        │
+[Layer 1: Fundamental Catalog Primitives]
+   ├── Units of Measure (kg, pcs, cm, l, etc.)
+   ├── Brands (Manufacturers, Trademarks, Logos)
+   └── Categories (Nested Hierarchy, Slugs, Breadcrumbs)
+        │
+[Layer 2: Attribute & Classification Engine]
+   ├── Attributes (Types, Validations, Regex, Options)
+   ├── Attribute Groups (UI Organizers & Logical Groupings)
+   └── Attribute Sets (Templates combining multiple Groups)
+        │
+[Layer 3: Media & Digital Asset Management (DAM)]
+   ├── Asset Types (Hero, Gallery, Manuals, Spec Sheets)
+   ├── Asset Families (Required Media Rules & Validations)
+   └── Central File Registry (S3 / Local Storage, URLs, MIME)
+        │
+[Layer 4: Blueprint Orchestration (Product Family / Catalog)]
+   ├── Family Blueprint Definition (Inherits Category + Set)
+   ├── Variant Axis Rules (Size, Color, Storage, RAM)
+   ├── Media Requirements (Minimum Asset Dimensions & Formats)
+   └── Channel Syndication Subscriptions (Shopify, Amazon, CSV)
+        │
+[Layer 5: Product Core Entity & Lifecycle Engine]
+   ├── Draft Creation (POST /api/v1/products)
+   ├── Dynamic Attribute Persistence (EAV / JSONB Hybrid)
+   ├── Variant Matrix Generator (Cartesian Product of Axes)
+   ├── Asset Role Assignment (Hero Image, Gallery, Video)
+   ├── Channel Scoping & Overrides
+   └── Completeness Engine (Automated 0-100% Scoring)
+```
+
+---
+
+## 4. Architectural Rules & Invariants
+1. **Tenant Isolation**: Every database query in multi-tenant mode MUST enforce `tenant_id` scoping to prevent data leakage between organizations.
+2. **Soft Deletes (`paranoid: true`)**: Deleting any primitive (Category, Attribute, Product, Unit, Brand) sets `deleted_at = NOW()`. Hard deletion is strictly disallowed to preserve audit integrity.
+3. **SKU Invariant**: 
+   - A Product in `draft` status may have `sku = null`.
+   - A Product transitioning to `pending` or `active` MUST have a globally unique SKU (either manually supplied or auto-generated by the Sequence Engine).
+4. **Code Normalization**: `code` across all entities (Categories, Attributes, Units, Families, Products) must be lowercase, alphanumeric, and underscore-delimited (e.g., `tech_electronics_01`).
+5. **Data Completeness Independence**: A product's completeness score is computed per channel and locale, evaluating mandatory general fields, required attributes, DAM media assets, and syndication channels.

+# 🔗 Dependent Entities & Cascading Architecture
+
+## 1. Overview
+A Product in modern PIM is not an isolated table row; it is an aggregated composite entity. This document details each sub-primitive, its database schema, cascade behaviors, and lifecycle rules.
+
+---
+
+## 2. Taxonomy & Hierarchy (Categories)
+
+### Data Architecture
+Categories are modeled as an Adjacency List hierarchy using self-referencing `parent_id`.
+
+```mermaid
+graph TD
+    Root[Root: Electronics] --> Audio[Category: Audio & Sound]
+    Audio --> Headphones[Subcategory: Wireless Headphones]
+    Audio --> Speakers[Subcategory: Bluetooth Speakers]
+    Root --> Computers[Category: Computers & Laptops]
+```
+
+### Inheritance & Rules
+- **Category Inheritance**: When selecting a `Product Family`, the product automatically inherits the family's default category if none is set.
+- **Slug Normalization**: Slugs are generated recursively (`electronics/audio-sound/wireless-headphones`).
+- **Cascade Rule**: Deleting a category does NOT delete products; it sets product `category_id = NULL` to prevent orphaned cascades.
+
+---
+
+## 3. Brand & Manufacturer Registry
+
+### Data Architecture
+Brands store trademark data, manufacturer info, and logo DAM assets.
+
+### Blueprint Filtering
+- Product Families define `allowedBrands` in their blueprint.
+- When creating a product from a family, the UI automatically filters the Brand dropdown to only include allowed brands.
+- If allowed brands is empty, all active workspace brands are selectable.
+
+---
+
+## 4. Units of Measure (UOM) Engine
+
+### Data Architecture & Conversions
+- `unit_type`: Categorizes units (`Weight`, `Length`, `Volume`, `Count`, `Other`).
+- `conversion_factor`: Standard multiplier against a base unit (e.g. `g` has factor `0.001` relative to base unit `kg`).
+- **Conflict Handling**: The inline unit creation endpoint enforces unique code constraints. On `HTTP 409 Conflict`, the frontend auto-selects the existing unit matching the code/name to prevent workflow interruption.
+
+---
+
+## 5. Attributes, Sets & Groups (The EAV Model)
+
+### Hierarchy Model
+```mermaid
+graph TD
+    Set[Attribute Set: Electronics Set] --> G1[Group: Technical Specifications]
+    Set --> G2[Group: Physical Dimensions]
+    Set --> G3[Group: Marketing & Media]
+    
+    G1 --> A1[Attribute: Connectivity]
+    G1 --> A2[Attribute: Battery Life]
+    G2 --> A3[Attribute: Weight Grams]
+    G2 --> A4[Attribute: Color Spec]
+    G3 --> A5[Attribute: SEO Title]
+```
+
+### Supported Attribute Types & Validations
+1. `text`: String values with `min_length` and `max_length`.
+2. `textarea`: Multi-line text for descriptions and spec tables.
+3. `number` / `decimal`: Integer or floating-point numbers with `min_value` and `max_value` limits (e.g., non-negative `min: 0` for physical weights).
+4. `date`: ISO date format (`YYYY-MM-DD`).
+5. `boolean`: Binary `true` / `false` flags.
+6. `select`: Single-choice enumeration reading from `attribute_options` or `options` array.
+7. `multiselect`: Comma-delimited or JSON array of allowed choices.
+
+---
+
+## 6. Digital Asset Management (DAM) & Media Junction
+
+### Role Matrix
+| Role Code | Display Label | Purpose | Completeness Evaluation |
+| :--- | :--- | :--- | :--- |
+| `hero_image` | **HERO IMAGE** | Primary high-res catalog cover image | Evaluated for completeness (is_primary) |
+| `gallery_image`| **GALLERY** | Additional multi-angle product views | Optional supporting media |
+| `thumbnail` | **THUMBNAIL** | Low-res compressed preview icon | Optional UI thumbnail |
+| `video` | **VIDEO** | Product showcase video (MP4/WebM) | Optional media |
+| `document` | **DOCUMENT** | PDF user manuals, safety sheets | Optional compliance assets |
+
+---
+
+## 7. Completeness Calculation Mathematical Engine
+
+The PIM Data Completeness score is calculated as a real-time ratio (0% to 100%):
+
+$$\text{Completeness } \% = \text{round}\left( \frac{\text{Fulfilled Fields}}{\text{Total Expected Fields}} \times 100 \right)$$
+
+### Weighted Breakdown:
+1. **General Prerequisites (4 fields)**:
+   - `name` (Product Name present)
+   - `category_id` (Category assigned)
+   - `brand_id` (Brand assigned)
+   - `unit_id` (Unit of Measure assigned)
+2. **Evaluated Attributes**:
+   - Evaluates all configured attributes in the active Attribute Set.
+   - Each configured attribute value contributes proportionally to the attribute score.
+3. **Required Media Assets**:
+   - Evaluates mandatory asset families (e.g. at least 1 primary Hero Image).
+4. **Subscribed Syndication Channels**:
+   - Evaluates whether mandatory syndication channels are linked.

+# 🔍 System Gaps, Risk Audit & Optimization Blueprint
+
+## 1. Executive Summary
+This document captures architectural vulnerabilities, potential race conditions, database indexing requirements, and optimization blueprints identified during the comprehensive Product Creation deep-dive.
+
+---
+
+## 2. Identified Vulnerabilities & Audit Findings
+
+| Category | Finding & Risk | Impact | Resolution & Architecture Recommendation |
+| :--- | :--- | :--- | :--- |
+| **Concurrency** | Non-atomic SKU generation on concurrent product creations | Duplicate SKU generation if two products are created in the exact same millisecond | Use PostgreSQL sequence or database-level lock on `sku_counters` table rather than `COUNT(*)` lookups. |
+| **Data Integrity** | Soft-deleted attribute options lingering in product values | A product displays a deleted option code with no human-readable label | In `product_attribute_values`, store both `option_id` (FK) and string fallback, or enforce cascade warning on attribute option deletion. |
+| **Performance** | Missing composite index on `product_attribute_values` | Sluggish search queries when filtering products by multiple attribute values | Add compound index: `CREATE INDEX idx_pav_attr_val ON product_attribute_values(attribute_id, value);` |
+| **Tenant Scope** | In-memory filtering instead of database query scoping | Unnecessary memory overhead fetching cross-tenant records | Always apply `where: { tenant_id }` in repository layer before executing Sequelize `findAll()`. |
+
+---
+
+## 3. High-Priority Database Indexing Strategy
+
+To guarantee sub-50ms response times for a catalog containing 500,000+ products:
+
+```sql
+-- 1. Product Registry Primary Lookups
+CREATE INDEX IF NOT EXISTS idx_products_tenant_status ON products(tenant_id, status) WHERE deleted_at IS NULL;
+CREATE INDEX IF NOT EXISTS idx_products_code_tenant ON products(code, tenant_id);
+CREATE INDEX IF NOT EXISTS idx_products_sku_tenant ON products(sku, tenant_id);
+CREATE INDEX IF NOT EXISTS idx_products_family ON products(family_id);
+CREATE INDEX IF NOT EXISTS idx_products_category ON products(category_id);
+CREATE INDEX IF NOT EXISTS idx_products_brand ON products(brand_id);
+
+-- 2. Dynamic Attribute EAV Indexing
+CREATE INDEX IF NOT EXISTS idx_pav_product_attr ON product_attribute_values(product_id, attribute_id);
+CREATE INDEX IF NOT EXISTS idx_pav_attr_value ON product_attribute_values(attribute_id, value);
+
+-- 3. Completeness Indexing
+CREATE INDEX IF NOT EXISTS idx_completeness_product_channel ON product_completeness(product_id, channel, locale);
+
+-- 4. Media Asset Junction Indexing
+CREATE INDEX IF NOT EXISTS idx_product_assets_product_primary ON product_assets(product_id, is_primary);
+```
+
+---
+
+## 4. Architectural Next Steps & Roadmap
+1. **Bulk Product Import & Syndication Queue**: Implement Redis / BullMQ worker pipeline for processing 10,000+ CSV / XML product imports asynchronously with streaming batch inserts.

+# 📋 Product Listing & Query Engine Architecture
+
+## 1. Overview
+The Product Listing system (`GET /api/v1/products`) powers the core catalog data grid. It supports multi-facet filtering (by category, brand, family, completeness, channel, status, tag, and custom attributes), full-text search across product name and SKU, server-side pagination, eager-loading of primary hero assets, and real-time completeness score aggregation.
+
+---
+
+## 2. API Endpoint Specification
+
+- **Endpoint**: `GET /api/v1/products`
+- **Query Parameters**:
+  - `page` (integer, default: 1)
+  - `limit` (integer, default: 20, max: 100)
+  - `search` (string, fuzzy search on `name`, `code`, `sku`)
+  - `status` (string or array: `draft`, `pending`, `active`, `archived`)
+  - `type` (string: `simple`, `variant`, `bundle`)
+  - `family_id` (UUID)
+  - `category_id` (UUID, matches category and its descendant subtrees)
+  - `brand_id` (UUID)
+  - `completeness_min` / `completeness_max` (integers 0-100)
+  - `channel` (string, e.g. `shopify`, `amazon`)
+  - `sortBy` (`name`, `sku`, `created_at`, `updated_at`, `completeness`, `price`)
+  - `sortOrder` (`ASC` or `DESC`)
+
+---
+
+## 3. Query Optimization & Eager-Loading Structure
+
+To avoid the $N+1$ query problem, the product listing query uses targeted eager-loading with selected columns:
+
+```javascript
+const queryOptions = {
+  where: baseWhereClause,
+  attributes: [
+    'id', 'code', 'sku', 'name', 'price', 'stock', 'status', 'type',
+    'family_id', 'category_id', 'brand_id', 'unit_id', 'created_at', 'updated_at'
+  ],
+  include: [
+    {
+      model: models.Catalog,
+      as: 'family',
+      attributes: ['id', 'code', 'name']
+    },
+    {
+      model: models.Category,
+      as: 'category',
+      attributes: ['id', 'code', 'name', 'slug']
+    },
+    {
+      model: models.Brand,
+      as: 'brand',
+      attributes: ['id', 'code', 'name', 'logo_url']
+    },
+    {
+      model: models.Unit,
+      as: 'unit',
+      attributes: ['id', 'code', 'name', 'symbol']
+    },
+    {
+      model: models.ProductAsset,
+      as: 'productAssets',
+      where: { is_primary: true },
+      required: false,
+      include: [
+        {
+          model: models.Asset,
+          as: 'asset',
+          attributes: ['id', 'url', 'thumbnail_url', 'name', 'mime_type']
+        }
+      ]
+    },
+    {
+      model: models.ProductCompleteness,
+      as: 'completenessEntries',
+      where: { channel: 'default' },
+      required: false,
+      attributes: ['percentage', 'is_complete', 'missing_attributes', 'missing_assets']
+    }
+  ],
+  order: [[sortField, sortOrder]],
+  limit,
+  offset: (page - 1) * limit
+};
+```
+
+---
+
+## 4. Frontend Data Grid Hydration & Performance
+- **Primary Hero Image**: Displayed as a responsive 40x40 thumbnail from `productAssets[0].asset.thumbnail_url || productAssets[0].asset.url`.
+- **Completeness Indicator**: Circular or pill progress badge colored dynamically:
+  - `0 - 49%`: Red (Incomplete)
+  - `50 - 84%`: Amber (Partially Configured)
+  - `85 - 99%`: Blue (Ready for Review)
+  - `100%`: Emerald Green (Fully Complete & Ready for Publish)
+- **Fast Filter Sync**: Search query debounced at 300ms, updating URL search params to preserve filter state on browser reload.
