+**Analysis of Potential Issues**
+
+1.  **Obsolete Functionality:**
+    *   **`config.js` Legacy Endpoints:** The endpoints `GET /config/`, `PUT /config/stock-thresholds/:id`, `PUT /config/lead-time-thresholds/:id`, `PUT /config/sales-velocity/:id`, `PUT /config/abc-classification/:id`, `PUT /config/safety-stock/:id`, and `PUT /config/turnover/:id` appear **highly likely to be obsolete**. They reference older, single-row config tables (`stock_thresholds`, etc.) while newer endpoints (`/config/global`, `/config/products`, `/config/vendors`) manage settings in more structured tables (`settings_global`, `settings_product`, `settings_vendor`). Unless specifically required for backward compatibility, these legacy endpoints should be removed to avoid confusion and potential data conflicts.
+    *   **`analytics.js` Forecast Endpoint (`GET /analytics/forecast`):** This endpoint uses **MySQL syntax** (`DATEDIFF`, `DATE_FORMAT`, `JSON_OBJECT`, `?` placeholders) but seems intended to run within the analytics module which otherwise uses PostgreSQL (`req.app.locals.pool`, `date_trunc`, `::text`, `$1` placeholders). This endpoint is likely **obsolete or misplaced** and will not function correctly against the PostgreSQL database.
+    *   **`csv.js` Redundant Actions:**
+        *   `POST /csv/update` seems redundant with `POST /csv/full-update`. The latter uses the `runScript` helper and dedicated state (`activeFullUpdate`), appearing more robust. `/csv/update` might be older or incomplete.
+        *   `POST /csv/reset` seems redundant with `POST /csv/full-reset`. Similar reasoning applies; `/csv/full-reset` appears preferred.
+    *   **`products.js` Import Endpoint (`POST /products/import`):** This is **dangerous duplication**. The `/csv` module handles imports (`/csv/import`, `/csv/import-from-prod`) with locking (`activeImport`) to prevent concurrent operations. This endpoint lacks such locking and could corrupt data if run simultaneously with other CSV/reset operations. It should likely be removed.
+    *   **`products.js` Metrics Endpoint (`GET /products/:id/metrics`):** This is redundant. The `/metrics/:pid` endpoint provides the same, possibly more comprehensive, data directly from the `product_metrics` table. Clients should use `/metrics/:pid` instead.
+
+2.  **Overlap or Inappropriate Duplication of Effort:**
+    *   **AI Prompt Getters:** `GET /ai-prompts/type/general` and `GET /ai-prompts/type/system` could potentially be handled by adding a query parameter filter to `GET /ai-prompts/` (e.g., `GET /ai-prompts?prompt_type=general`). However, dedicated endpoints for single, specific items can sometimes be simpler. This is more of a design choice than a major issue.
+    *   **Vendor Performance/Metrics:** There are multiple ways to get vendor performance data:
+        *   `GET /analytics/vendors` (uses `vendor_metrics`)
+        *   `GET /dashboard/vendor/performance` (uses `purchase_orders`)
+        *   `GET /purchase-orders/vendor-metrics` (uses `purchase_orders`)
+        *   `GET /vendors-aggregate/` (uses `vendor_metrics`, augmented with `purchase_orders`)
+        This suggests significant overlap. The `/vendors-aggregate` endpoint seems the most comprehensive, combining pre-aggregated data with some real-time info. The others, especially `/dashboard/vendor/performance` and `/purchase-orders/vendor-metrics` which calculate directly from `purchase_orders`, might be redundant or less performant.
+    *   **Product Listing:**
+        *   `GET /products/` lists products joining `products`, `product_metrics`, and `categories`.
+        *   `GET /metrics/` lists products primarily from `product_metrics`.
+        They offer similar filtering/sorting. If `product_metrics` contains all necessary display fields, `GET /products/` might be partly redundant for simple listing views, although it does provide aggregated category names. Evaluate if both full list endpoints are necessary.
+    *   **Image Uploads/Management:** Image handling is split:
+        *   `products-import.js`: Uploads temporary images for product import to `/uploads/products/`, schedules deletion.
+        *   `reusable-images.js`: Uploads persistent images to `/uploads/reusable/`, stores metadata in DB.
+        *   `products-import.js` has `/check-file` and `/list-uploads` that can see *both* directories, while `reusable-images.js` has a `/check-file` that only sees its own. This separation could be confusing. Clarify the purpose and lifecycle of images in each directory.
+    *   **Background Task Management (`csv.js`):** The use of `activeImport` for multiple unrelated tasks (import, reset, metrics calc) prevents concurrency, which might be too restrictive. The cancellation logic (`/cancel`) only targets `full-update`/`full-reset`, not tasks locked by `activeImport`. This needs unification.
+    *   **Analytics/Dashboard Base Table Queries:** Several endpoints in `analytics.js` (`/pricing`, `/categories`) and `dashboard.js` (`/best-sellers`, `/sales/metrics`, `/trending/products`, `/key-metrics`, `/inventory-health`, `/sales-overview`) query base tables (`orders`, `products`, `purchase_orders`) directly, while many others leverage pre-aggregated `_metrics` tables. This inconsistency can lead to performance differences and suggests potential for optimization by using aggregates where possible.
+
+3.  **Obvious Mistakes / Data Issues:**
+    *   **AI Prompt Fetching:** `GET /ai-prompts/company/:companyId`, `/type/general`, `/type/system` return `result.rows[0]`. This assumes uniqueness. If the underlying DB constraints (`unique_company_prompt`, etc.) fail or aren't present, this could silently hide data if multiple rows match. The use of unique constraint handling in POST/PUT suggests this is likely intended and safe *if* DB constraints are solid.
+    *   **Mixed Databases & SSH Tunnels:** The heavy reliance in `ai_validation.js` and `products-import.js` on connecting to a production MySQL DB via SSH tunnel while also using a local PostgreSQL DB adds significant architectural complexity.
+        *   **Inefficiency:** In `ai_validation.js` (`generateDebugResponse`), an SSH tunnel and MySQL connection (`promptTunnel`, `promptConnection`) are established but seem unused when fetching prompts (which correctly come from the PG pool `res.app.locals.pool`). This is wasted effort.
+        *   **Improvement:** The `getDbConnection` function in `products-import.js` implements caching/pooling for the SSH/MySQL connection – this is much better and should ideally be used consistently wherever the production DB is accessed (e.g., in `ai_validation.js`).
+    *   **`products.js` Brand Filtering:** `GET /products/brands` filters brands based on having associated purchase orders with a cost >= 500. This seems arbitrary for a general list of brands and might return incomplete results depending on the use case.
+    *   **Type Handling:** Ensure `parseValue` handles all required types and edge cases correctly, especially for filtering complex queries in `*-aggregate` and `metrics` routes. Explicit type casting in SQL (`::numeric`, `::text`, etc.) is generally good practice in PostgreSQL.
+    *   **Dummy Data:** Several `dashboard.js` endpoints return hardcoded dummy data on errors or when no data is found. While this prevents UI crashes, it can mask real issues. Ensure logging is robust when fallbacks are used.

+
+**Recommendations:**
+
+1.  **Address Obsolete Endpoints:** Prioritize removing or confirming the necessity of the endpoints marked as obsolete/redundant (legacy config, `/analytics/forecast`, `/csv/update`, `/csv/reset`, `/products/import`, `/products/:id/metrics`).
+2.  **Consolidate Overlapping Functionality:** Review the multiple vendor performance and product listing endpoints. Decide on the primary method (e.g., using aggregate tables via `/vendors-aggregate` and `/metrics`) and refactor or remove the others. Clarify the image upload strategies.
+3.  **Standardize Data Access:** Decide whether `dashboard` and `analytics` endpoints should primarily use aggregate tables (like `/metrics`, `/brands-aggregate`, etc.) or if direct access to base tables is sometimes necessary. Aim for consistency and document the reasoning. Optimize queries hitting base tables if they must remain.
+4.  **Improve Background Task Management:** Refactor `csv.js` to use a unified locking mechanism (maybe separate locks per task type?) and a consistent cancellation strategy for all spawned/managed processes. Clarify the purpose of `update` vs `full-update` and `reset` vs `full-reset`.
+5.  **Optimize DB Connections:** Ensure the `getDbConnection` pooling/caching helper from `products-import.js` is used *consistently* across all modules interacting with the production MySQL database (especially `ai_validation.js`). Remove unnecessary tunnel creations.
+6.  **Review Data Integrity:** Double-check the assumptions made (e.g., uniqueness of AI prompts) and ensure database constraints enforce them. Review the `GET /products/brands` filtering logic.
+
+## Changes Made
+
+1. **Removed Obsolete Legacy Endpoints in `config.js`**:
+   - Removed `GET /config/` endpoint
+   - Removed `PUT /config/stock-thresholds/:id` endpoint
+   - Removed `PUT /config/lead-time-thresholds/:id` endpoint
+   - Removed `PUT /config/sales-velocity/:id` endpoint
+   - Removed `PUT /config/abc-classification/:id` endpoint
+   - Removed `PUT /config/safety-stock/:id` endpoint
+   - Removed `PUT /config/turnover/:id` endpoint
+   
+   These endpoints were obsolete as they referenced older, single-row config tables that have been replaced by newer endpoints using the structured tables `settings_global`, `settings_product`, and `settings_vendor`.
+
+2. **Removed MySQL Syntax `/forecast` Endpoint in `analytics.js`**:
+   - Removed `GET /analytics/forecast` endpoint that was using MySQL-specific syntax incompatible with the PostgreSQL database used elsewhere in the application.
+
+3. **Renamed and Removed Redundant Endpoints**:
+   - Renamed `csv.js` to `data-management.js` while maintaining the same `/csv/*` endpoint paths for consistency
+   - Removed deprecated `/csv/update` endpoint (now fully replaced by `/csv/full-update`)
+   - Removed deprecated `/csv/reset` endpoint (now fully replaced by `/csv/full-reset`)
+   - Removed deprecated `/products/import` endpoint (now handled by `/csv/import`)
+   - Removed deprecated `/products/:id/metrics` endpoint (now handled by `/metrics/:pid`)
+
+4. **Fixed Data Integrity Issues**:
+   - Improved `GET /products/brands` endpoint by removing the arbitrary filtering logic that was only showing brands with purchase orders that had a total cost of at least $500
+   - The updated endpoint now returns all distinct brands from visible products, providing more complete data
+
+5. **Optimized Database Connections**:
+   - Created a new `dbConnection.js` utility file that encapsulates the optimized database connection management logic
+   - Improved the `ai-validation.js` file to use this shared connection management, eliminating unnecessary repeated tunnel creation
+   - Added proper connection pooling with timeout-based connection reuse, reducing the overhead of repeatedly creating SSH tunnels
+   - Added query result caching for frequently accessed data to improve performance
+
+These changes improve maintainability by removing duplicate code, enhance consistency by standardizing on the newer endpoint patterns, and optimize performance by reducing redundant database connections.
+
+## Additional Improvements
+
+1. **Further Database Connection Optimizations**:
+   - Extended the use of the optimized database connection utility to additional endpoints in `ai-validation.js`
+   - Updated the `/validate` endpoint and `/test-taxonomy` endpoint to use `getDbConnection`
+   - Ensured consistent connection management across all routes that access the production database
+
+2. **AI Prompts Data Integrity Verification**:
+   - Confirmed proper uniqueness constraints are in place in the database schema for AI prompts
+   - The schema includes:
+     - `unique_company_prompt` constraint ensuring only one prompt per company
+     - `idx_unique_general_prompt` index ensuring only one general prompt in the system
+     - `idx_unique_system_prompt` index ensuring only one system prompt in the system
+   - Endpoint handlers properly handle uniqueness constraint violations with appropriate 409 Conflict responses
+   - Validation ensures company-specific prompts have company IDs, while general/system prompts do not
+
+3. **AI Prompts Endpoint Consolidation**:
+   - Added a new consolidated `/by-type` endpoint that handles all types of prompts (general, system, company_specific)
+   - Marked the existing separate endpoints as deprecated with console warnings
+   - Maintained backward compatibility while providing a cleaner API moving forward
