+# Permission System Documentation
+
+This document outlines the permission system implemented in the Inventory Manager application.
+
+## Permission Structure
+
+Permissions follow this naming convention:
+
+- Page access: `access:{page_name}`
+- Actions: `{action}:{resource}`
+
+Examples:
+- `access:products` - Can access the Products page
+- `create:products` - Can create new products
+- `edit:users` - Can edit user accounts
+
+## Permission Components
+
+### PermissionGuard
+
+The core component that conditionally renders content based on permissions.
+
+```tsx
+<PermissionGuard 
+  permission="create:products"
+  fallback={<p>No permission</p>}
+>
+  <button>Create Product</button>
+</PermissionGuard>
+```
+
+Options:
+- `permission`: Single permission code
+- `anyPermissions`: Array of permissions (ANY match grants access)
+- `allPermissions`: Array of permissions (ALL required)
+- `adminOnly`: For admin-only sections
+- `page`: Page name (checks `access:{page}` permission)
+- `fallback`: Content to show if permission check fails
+
+### PermissionProtectedRoute
+
+Protects entire pages based on page access permissions.
+
+```tsx
+<Route path="/products" element={
+  <PermissionProtectedRoute page="products">
+    <Products />
+  </PermissionProtectedRoute>
+} />
+```
+
+### ProtectedSection
+
+Protects sections within a page based on action permissions.
+
+```tsx
+<ProtectedSection page="products" action="create">
+  <button>Add Product</button>
+</ProtectedSection>
+```
+
+### PermissionButton
+
+Button that automatically handles permissions.
+
+```tsx
+<PermissionButton 
+  page="products" 
+  action="create"
+  onClick={handleCreateProduct}
+>
+  Add Product
+</PermissionButton>
+```
+
+### SettingsSection
+
+Specific component for settings with built-in permission checks.
+
+```tsx
+<SettingsSection
+  title="System Settings"
+  description="Configure global settings"
+  permission="edit:system_settings"
+>
+  {/* Settings content */}
+</SettingsSection>
+```
+
+## Permission Hooks
+
+### usePermissions
+
+Core hook for checking any permission.
+
+```tsx
+const { hasPermission, hasPageAccess, isAdmin } = usePermissions();
+if (hasPermission('delete:products')) {
+  // Can delete products
+}
+```
+
+### usePagePermission
+
+Specialized hook for page-level permissions.
+
+```tsx
+const { canView, canCreate, canEdit, canDelete } = usePagePermission('products');
+if (canEdit()) {
+  // Can edit products
+}
+```
+
+## Database Schema
+
+Permissions are stored in the database:
+- `permissions` table: Stores all available permissions
+- `user_permissions` junction table: Maps permissions to users
+
+Admin users automatically have all permissions.
+
+## Common Permission Codes
+
+| Code | Description |
+|------|-------------|
+| `access:dashboard` | Access to Dashboard page |
+| `access:products` | Access to Products page |
+| `create:products` | Create new products |
+| `edit:products` | Edit existing products |
+| `delete:products` | Delete products |
+| `view:users` | View user accounts |
+| `edit:users` | Edit user accounts |
+| `manage:permissions` | Assign permissions to users |
+
+## Implementation Examples
+
+### Page Protection
+
+In `App.tsx`:
+```tsx
+<Route path="/products" element={
+  <PermissionProtectedRoute page="products">
+    <Products />
+  </PermissionProtectedRoute>
+} />
+```
+
+### Component Level Protection
+
+```tsx
+const { canEdit } = usePagePermission('products');
+
+function handleEdit() {
+  if (!canEdit()) {
+    toast.error("You don't have permission");
+    return;
+  }
+  // Edit logic
+}
+```
+
+### UI Element Protection
+
+```tsx
+<PermissionButton 
+  page="products" 
+  action="delete"
+  onClick={handleDelete}
+>
+  Delete
+</PermissionButton>
+```

+# MySQL to PostgreSQL Import Process Documentation
+
+This document outlines the data import process from the production MySQL database to the local PostgreSQL database, focusing on column mappings, data transformations, and the overall import architecture.

+5. [Implementation Notes](#implementation-notes)
+
+## Overview
+
+The import process extracts data from a MySQL 5.7 production database and imports it into a PostgreSQL database. It can operate in two modes:
+
+- **Full Import**: Imports all data regardless of last sync time
+- **Incremental Import**: Only imports data that has changed since the last import
+
+The process handles four main data types:
+- Categories (product categorization hierarchy)
+- Products (inventory items)
+- Orders (sales records)
+- Purchase Orders (vendor orders)
+
+## Import Architecture
+
+The import process follows these steps:
+
+1. **Establish Connection**: Creates a SSH tunnel to the production server and establishes database connections
+2. **Setup Import History**: Creates a record of the current import operation
+3. **Import Categories**: Processes product categories in hierarchical order
+4. **Import Products**: Processes products with their attributes and category relationships
+5. **Import Orders**: Processes customer orders with line items, taxes, and discounts
+6. **Import Purchase Orders**: Processes vendor purchase orders with line items
+7. **Record Results**: Updates the import history with results
+8. **Close Connections**: Cleans up connections and resources
+
+Each import step uses temporary tables for processing and wraps operations in transactions to ensure data consistency.
+
+## Column Mappings
+
+### Categories
+| PostgreSQL Column | MySQL Source                    | Transformation                               |
+|-------------------|---------------------------------|----------------------------------------------|
+| cat_id            | product_categories.cat_id       | Direct mapping                               |
+| name              | product_categories.name         | Direct mapping                               |
+| type              | product_categories.type         | Direct mapping                               |
+| parent_id         | product_categories.master_cat_id| NULL for top-level categories (types 10, 20) |
+| description       | product_categories.combined_name| Direct mapping                               |
+| status            | N/A                             | Hard-coded 'active'                          |
+| created_at        | N/A                             | Current timestamp                            |
+| updated_at        | N/A                             | Current timestamp                            |
+
+**Notes:**
+- Categories are processed in hierarchical order by type: [10, 20, 11, 21, 12, 13]
+- Type 10/20 are top-level categories with no parent
+- Types 11/21/12/13 are child categories that reference parent categories

+
+**Notes:**
+- Replenishable calculation: 
+  ```javascript
+  CASE 
+    WHEN p.reorder < 0 THEN 0
+    WHEN (
+      (COALESCE(pls.date_sold, '0000-00-00') = '0000-00-00' OR pls.date_sold <= DATE_SUB(CURRENT_DATE, INTERVAL 5 YEAR))
+      AND (p.datein = '0000-00-00 00:00:00' OR p.datein <= DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 5 YEAR))
+      AND (p.date_refill = '0000-00-00 00:00:00' OR p.date_refill <= DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 5 YEAR))
+    ) THEN 0
+    ELSE 1
+  END
+  ```
+
+In business terms, a product is considered NOT replenishable only if:
+- It was manually flagged as not replenishable (negative reorder value)
+- OR it shows no activity across ALL metrics (no sales AND no receipts AND no refills in the past 5 years)
+- Image URLs are constructed using this pattern:
+  ```javascript
+  const paddedPid = pid.toString().padStart(6, '0');
+  const prefix = paddedPid.slice(0, 3);
+  const basePath = `${imageUrlBase}${prefix}/${pid}`;
+  return {
+    image: `${basePath}-t-${iid}.jpg`,
+    image_175: `${basePath}-175x175-${iid}.jpg`,
+    image_full: `${basePath}-o-${iid}.jpg`
+  };
+  ```

+  1. Base discount: order_items.prod_price_reg - order_items.prod_price
+  2. Promo discount: SUM of order_discount_items.amount
+  3. Proportional order discount: Calculation based on order subtotal proportion
+  ```javascript

+    ELSE 0 
+   END)::DECIMAL(10,2)
+  ```
+- Taxes are taken from the latest tax record for an order
+- Cost data is taken from the latest non-pending cost record

+
+## Special Calculations
+
+### Date Validation
+
+MySQL dates are validated before insertion into PostgreSQL:
+
+```javascript
+function validateDate(mysqlDate) {
+  if (!mysqlDate || mysqlDate === '0000-00-00' || mysqlDate === '0000-00-00 00:00:00') {
+    return null;
+  }
+  // Check if the date is valid
+  const date = new Date(mysqlDate);
+  return isNaN(date.getTime()) ? null : mysqlDate;
+}
+```
+
+### Retry Mechanism
+
+Operations that might fail temporarily are retried with exponential backoff:
+
+```javascript
+async function withRetry(operation, errorMessage) {
+  let lastError;
+  for (let attempt = 1; attempt <= MAX_RETRIES; attempt++) {
+    try {
+      return await operation();
+    } catch (error) {
+      lastError = error;
+      console.error(`${errorMessage} (Attempt ${attempt}/${MAX_RETRIES}):`, error);
+      if (attempt < MAX_RETRIES) {
+        const backoffTime = RETRY_DELAY * Math.pow(2, attempt - 1);
+        await new Promise(resolve => setTimeout(resolve, backoffTime));
+      }
+    }
+  }
+  throw lastError;
+}
+```
+
+### Progress Tracking
+
+Progress is tracked with estimated time remaining:
+
+```javascript
+function estimateRemaining(startTime, current, total) {
+  if (current === 0) return "Calculating...";
+  const elapsedSeconds = (Date.now() - startTime) / 1000;
+  const itemsPerSecond = current / elapsedSeconds;
+  const remainingItems = total - current;
+  const remainingSeconds = remainingItems / itemsPerSecond;
+  return formatElapsedTime(remainingSeconds);
+}
+```
+
+## Implementation Notes
+
+### Transaction Management
+
+All imports use transactions to ensure data consistency:
+
+- **Categories**: Uses savepoints for each category type
+- **Products**: Uses a single transaction for the entire import
+- **Orders**: Uses a single transaction with temporary tables
+- **Purchase Orders**: Uses a single transaction with temporary tables
+
+### Memory Usage Optimization
+
+To minimize memory usage when processing large datasets:
+
+1. Data is processed in batches (100-5000 records per batch)
+2. Temporary tables are used for intermediate data
+3. Some queries use cursors to avoid loading all results at once
+
+### MySQL vs PostgreSQL Compatibility
+
+The scripts handle differences between MySQL and PostgreSQL:
+
+1. MySQL-specific syntax like `USE INDEX` is removed for PostgreSQL
+2. `GROUP_CONCAT` in MySQL becomes string operations in PostgreSQL
+3. Transaction syntax differences are abstracted in the connection wrapper
+4. PostgreSQL's `ON CONFLICT` replaces MySQL's `ON DUPLICATE KEY UPDATE`
+
+### SSH Tunnel
+
+Database connections go through an SSH tunnel for security:
+
+```javascript
+ssh.forwardOut(
+  "127.0.0.1",
+  0,
+  sshConfig.prodDbConfig.host,
+  sshConfig.prodDbConfig.port,
+  async (err, stream) => {
+    if (err) reject(err);
+    resolve({ ssh, stream });
+  }
+);
+```

-I will provide a JSON array with product data. Process the array by combining all products from validData and invalidData arrays into a single array, excluding any fields starting with “__”, such as “__index” or “__errors”. Process each product according to the reference guidelines below. If a field is not included in the data, do not include it in your response (e.g. do not include its key or any value) unless the specific field guidelines below say otherwise. If a product appears to be from an empty or entirely invalid line, do not include it in your response.
-
-Your response should be a JSON object with the following structure:
-{
-  "correctedData": [], // Array of corrected products
-  "changes": [], // Array of strings describing each change made
-  "warnings": [] // Array of strings with warnings or suggestions for manual review (see below for details)
-}
-
-IMPORTANT: For all fields that use IDs (categories, supplier, company, line, subline, ship_restrictions, tax_cat, artist, themes, etc.), you MUST return the ID values, not the display names. The system will handle converting IDs to display names.
-
-Using the provided guidelines, focus on:
-1. Correcting typos and any incorrect spelling or grammar
-2. Standardizing product names
-3. Correcting and enhancing descriptions by adding details, keywords, and SEO-friendly language
-4. Fixing any obvious errors or inconsistencies between similar products in measurements, prices, or quantities
-5. Adding correct categories, themes, and colors
-
-Use only the provided data and your own knowledge to make changes. Do not make assumptions or make up information that you're not sure about. If you're unable to make a change you're confident about, leave the field as is. All data passed in should be validated, corrected, and returned. All values returned should be strings, not numbers. Do not leave out any fields that were present in the original data.
-
-Possible reasons for including a warning in the warnings array:
-- If you're unable to make a change you're confident about but you believe one needs to be made
-- If there are inconsistencies in the data that could be valid but need to be reviewed
-- If not enough information is provided to make a change that you believe is needed
-- If you infer a value for a required field based on context

If a value is unusual or unreasonable, even wildly so, change it to match similar products or to be more reasonable. When correcting unreasonable weights or dimensions, prioritize comparisons to products from the same company and product line first, then broader category matches or common knowledge if necessary.Do not return 0 or null for any of these fields.

-Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
-Required: Return if present in the original data or if not present and applicable. Do not return if not applicable (e.g. if no size categories apply based on what you know about the product).
-Instructions: If present or if applicable, return one valid numerical size category ID from the Available Size Categories array below. Give preference to the value provided, but correct it if another value is more accurate. If the product name contains a match for one of the size categories (such as 12x12, 6x6, 2oz, etc) you MUST return that size category with the results. A value is not required if none of the size categories apply.
-
-Fields: themes
-Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
-Required: Return if present in the original data or if not present and applicable. Do not return any value if not applicable (e.g. if no themes apply based on what you know about the product).
-Instructions: If present, confirm that each provided theme matches what you understand to be a theme of the product. Remove any themes that do not match and add any themes that are missing.

-
-Fields: categories
-Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
-Required: You must always return at least one value for this field, even if it's not provided in the original data. If no value is provided, return the most appropriate category or categories based on the other information you have.
-Instructions: Always return a comma-separated list of one or more valid numerical category IDs from the Available Categories array below. Give preference to the values provided, particularly if the other information isn't enough to determine a category, but correct them or add new categories if another value is more accurate. Do not return categories in the Deals or Black Friday categories, and strip these from the list if present. If you choose a subcategory at any level, you do not need to include its parent categories in the list. You must return at least one category and you can return multiple categories if applicable. All categories have equal value so their order is not important. Always try to return the most specific categories possible (e.g. one in the third level of the category hierarchy is better than one in the second level).
-
-----------PRODUCT NAMING GUIDELINES----------
-If there's only one of this type of product in a line: [Line Name] [Product Name] - [Company]
-Example: "Cosmos Infinity Chipboard - Stamperia"
-Example: "Serene Petals 6x6 Paper Pad - Prima"
-

-Example: "Heart Tree Dies - Lawn Fawn"
-
-Color-based products: [Color] [Product Name] - [Company]
-Example: "Green Valley Enamel Dots - Altenew"
-Example: "Magenta Aqua Pigment - Brutus Monroe"
-
-Complex products: [Differentiator] [Line] [Product Type] - [Company]
-Example: "Size 6 Round Black Velvet Watercolor Brush - Silver Brush Limited" (Size 6 Round is the differentiator, Black Velvet is the line, Watercolor Brush is the product type)
-
-These should not be included in the name, unless there are multiple products that are otherwise identical:
-- Product size
-- Product weight
-- Number of pages
-- How many are in the package
-
-Naming Conventions:
-- Paper sizes: Use "12x12", "8x8", "6x6" (no spaces or units of measure)
-- Company names must match backend exactly
-- Always capitalize every word in the name, including short articles like "The" and "An"
-- Use "Idea-ology" (not "idea-ology" or "Ideaology")
-- All stamps are "Stamp Set" (not "Clear Stamps" or "Rubber Stamps")
-- All dies are "Dies" or "Die" (not "Die Set")
-- Brands with their own naming conventions should be respected, such as "Doodle Cuts" for dies from Doodlebug
-
-Special Brand Rules - Ranger: 
-Format: [Product Name] - [Designer Line] - Ranger
-Possible Designers: Dylusions, Dina Wakley MEdia, Simon Hurley create., Wendy Vecchi

-Examples:
-"Art Nouveau 3-D Textured Impressions Embossing Folder - Sizzix"
-"Pocket Pals Thinlits Dies - Sizzix"
-"Butterfly Wishes Framelits Dies & Stamps - Sizzix"
-
-Important Notes
-- Ensure that product names are consistent across all products of the same type
-- Use the minimum amount of information needed to uniquely identify the product
-- Put detailed specifications in the product description, not its name
-
-Edge Cases
-- If the product is missing a company name, infer one from the other products included in the data
-- If the product is missing a clear differentiator and needs one to be unique, infer and add one from the other data provided (e.g. the description, existing size categories, etc.)
-
-Incorrect example: MVP Rugby - Collection Pack - Photoplay
-Notes: there should be no dash between the line and the product
-
-Incorrect Example: A2 Easel Cards - Black - Photoplay
-Notes: the differentiating factor should come first: “Black A2 Easel Cards - Photoplay”. Size is ok to include here because this is the name printed on the package.
-
-Incorrect Example: 6” - Scriber Needle Modeling Tool
-Notes: this product only comes in one size, so 6” isn’t needed. The company name should also be included.
-
-Incorrect Example: Slick - White - Tulip Dimensional Fabric Paint 4oz
-Notes: color should be first, then type, then product, then company, so “White Slick Dimensional Fabric Paint - Tulip”. It appears there’s only one size available so no need to differentiate in the name.
-
-Incorrect Example: Silhouette Adhesive Cork Sheets 5”X7” 8/Pkg
-Notes: should be “Adhesive Cork Sheets - Silhouette”
-
-Incorrect Example: Galaxy - Opaque - American Crafts Color Pour Resin Dyes
-Notes: “Galaxy Opaque Dye Set - Color Pour Resin - American Crafts”
-
-Incorrect Example: Slate - Lion Brand Truboo Yarn
-Notes: [Differentiator] [Line] [Product Type] - [Company] : “Slate Truboo Yarn - Lion Brand”
-
-Incorrect Example: Rose Quartz Dylusions Shimmer Paint
-Notes: “Rose Quartz Shimmer Paint - Dylusions - Ranger”
-
-
-----------PRODUCT DESCRIPTION GUIDELINES----------
-Product descriptions are an extremely important part of the listing and are the most important part of your response. Care should be taken to ensure they are correct, helpful, and SEO-friendly.
-
-If a description is provided in the data, use it as a starting point. Correct any spelling errors, typos, poor grammar, or awkward phrasing. If necessary and you have the information, add more details, describe how the customer could use it, etc. Use complete sentences and keep SEO in mind.
-
-If no description is provided, make one up using the product name, the information you have, and the other provided guidelines. At minimum, a description should be one complete sentence that starts with a capital letter and ends with a period. Unless the product is extremely complex, 2-4 sentences is usually sufficient if you have enough information.
-
-Important Notes:
-- Every description should state exactly what's included in the product (e.g. "Includes one 12x12 sheet of patterned cardstock." or "Includes one 6x12 sheet with 27 unique stickers." or "Includes 55 pieces." or "Package includes machine, power cord, 12 sheets of cardstock, 3 dies, and project instructions.")
-- Do not use the word "our" in the description (this usually shows up when we copy a description from the manufacturer). Instead use "these" or "[Company name] [product]" or similar. (e.g. don't use "Our journals are hand-made in the USA", instead use "These journals are hand made..." or "Archer & Olive journals are handmade...")
-- Don't include statements that add no value like “this is perfect for all your paper crafts”. If the product helps to solve a unique problem or has a unique feature, by all means describe it, but if it’s just a normal sheet of paper or pack of stickers, you don’t have to pretend like it’s the best thing ever. At the same time, ensure that you add enough copy to ensure good SEO.
-- State as many facts as you can about the product, considering the viewpoint of the customer and what they would want to know when looking at it. They probably want to know dimensions, what products it’s compatible with, how thick the paper is, how many sheets are included, whether the sheets are double-sided or not, which items are in the kit, etc. Say as much as you possibly can with the information that you have.
-- !!DO NOT make up information if you aren't sure about it. A minimal correct description is better than a long incorrect one!!
-
-Avoid/remove:
-- The word "Imported"
-- Any warnings about Prop 65, choking hazards, etc
-- The manufacturer's name if it's included as the very first thing in the description
-- Any statement similar to "comes in a variety of colors, each sold separately"

+# Permission System Documentation
+
+This document outlines the simplified permission system implemented in the Inventory Manager application.
+
+## Permission Structure
+
+Permissions follow this naming convention:
+
+- Page access: `access:{page_name}`
+- Actions: `{action}:{resource}`
+
+Examples:
+- `access:products` - Can access the Products page
+- `create:products` - Can create new products
+- `edit:users` - Can edit user accounts
+
+## Permission Component
+
+### Protected
+
+The core component that conditionally renders content based on permissions.
+
+```tsx
+<Protected 
+  permission="create:products"
+  fallback={<p>No permission</p>}
+>
+  <button>Create Product</button>
+</Protected>
+```
+
+Options:
+- `permission`: Single permission code (e.g., "create:products")
+- `page`: Page name (checks `access:{page}` permission)
+- `resource` + `action`: Resource and action (checks `{action}:{resource}` permission)
+- `adminOnly`: For admin-only sections
+- `fallback`: Content to show if permission check fails
+
+### RequireAuth
+
+Used for basic authentication checks (is user logged in?).
+
+```tsx
+<Route element={
+  <RequireAuth>
+    <MainLayout />
+  </RequireAuth>
+}>
+  {/* Protected routes */}
+</Route>
+```
+
+## Common Permission Codes
+
+| Code | Description |
+|------|-------------|
+| `access:dashboard` | Access to Dashboard page |
+| `access:products` | Access to Products page |
+| `create:products` | Create new products |
+| `edit:products` | Edit existing products |
+| `delete:products` | Delete products |
+| `view:users` | View user accounts |
+| `edit:users` | Edit user accounts |
+| `manage:permissions` | Assign permissions to users |
+
+## Implementation Examples
+
+### Page Protection
+
+In `App.tsx`:
+```tsx
+<Route path="/products" element={
+  <Protected page="products" fallback={<Navigate to="/" />}>
+    <Products />
+  </Protected>
+} />
+```
+
+### Component Level Protection
+
+```tsx
+<Protected permission="edit:products">
+  <form>
+    {/* Form fields */}
+    <button type="submit">Save Changes</button>
+  </form>
+</Protected>
+```
+
+### Button Protection
+
+```tsx
+<Button 
+  onClick={handleDelete}
+  disabled={!hasPermission('delete:products')}
+>
+  Delete
+</Button>
+
+// With Protected component
+<Protected permission="delete:products" fallback={null}>
+  <Button onClick={handleDelete}>Delete</Button>
+</Protected>
+```
