 ### Architecture
 
-This module extends the product origin information system to use free-text fields instead of structured country/state fields.
+This module adds a simple free-text origin field to products.
 
 **Models:**
 
-1. **product.supplierinfo** - Base model with the `origin_text` field
-   - Field: `origin_text` (Char, translate=True)
+1. **product.template** - Base model with the `origin_text` field
+   - Field: `origin_text` (Char)
    - This is where the actual data is stored
-   - Each supplier can have a different origin text for the same product
+   - Editable directly on the product form
 
-2. **product.template** - Computed field
-   - Field: `origin_text` (Char, computed, store=False)
-   - Computes from main vendor's supplierinfo
-   - Depends on: `main_seller_id`, `variant_seller_ids.origin_text`
+2. **product.product** - Related field for variant access
+   - Field: `origin_text` (Char, related to `product_tmpl_id.origin_text`)
+   - `readonly=False` allows editing from variant views
+   - Changes propagate to the template
 
-3. **product.product** - Computed field (variant level)
-   - Field: `origin_text` (Char, computed, store=False)
-   - Computes from main vendor's supplierinfo
-   - Depends on: `product_tmpl_id.main_seller_id`, `seller_ids.origin_text`
+### Why This Architecture?
 
-### Why Computed Fields Instead of Related?
+The `origin_text` field is stored in `product.template` because:
 
-The `origin_text` field in `product.template` and `product.product` cannot be a simple `related` field because:
+- Origin typically applies to all variants of a product
+- Simplifies data management (one source of truth)
+- Avoids duplication across variants
+- Standard Odoo pattern for product-level attributes
 
-- `main_seller_id` is a `res.partner` record
-- `origin_text` is stored in `product.supplierinfo` records
-- We need to find the supplierinfo record where `partner_id == main_seller_id`
+The related field in `product.product` with `readonly=False` allows:
 
-This requires a computed field with custom logic to filter and find the correct supplierinfo record.
+- Seamless access from variant views
+- Editing from either template or variant forms
+- Automatic synchronization between template and variants
 
-### Translation Support
+### Previous Architecture (Deprecated)
 
-The `origin_text` field in `product.supplierinfo` uses `translate=True`, which means:
+The previous version stored `origin_text` in `product.supplierinfo` with computed
+fields in template/product. This was deprecated because:
 
-- Each language can have a different value
-- Translations are stored in Odoo's translation system
-- When switching languages, the field shows the translated value
-- If no translation exists, it falls back to the default language value
-
-### Store Strategy
-
-The computed fields in product template and product use `store=False` because:
-
-- The value should always reflect the current main vendor
-- If the main vendor changes or its origin text is updated, the product's origin should update automatically
-- No need to store redundant data
-- Reduces database size and update complexity
+- Supplierinfo records don't always exist when products are created
+- Added unnecessary complexity with computed fields
+- Required `product_main_seller` dependency
+- Origin semantically belongs to the product, not the supplier relationship
 
 ### Dependencies
 
-- **product** - Core product module
-- **product_main_seller** - Provides `main_seller_id` computed field for products
-
-### Relationship to product_origin
-
-This module is a replacement/alternative to the OCA `product_origin` module:
-
-- `product_origin` provides structured fields (country_id, state_id)
-- `product_origin_char` provides free-text field (origin_text)
-- Both cannot be installed simultaneously without potential conflicts
-- This module was created because suppliers use creative, non-standardized origin descriptions
+- **product** - Core product module (only dependency)
 
 ### Performance Considerations
 
-- Computed fields with `store=False` are calculated on-the-fly
-- Performance is acceptable because the computation is simple (filter + get first)
-- If performance becomes an issue, consider:
-  - Adding `store=True` with proper dependencies
-  - Adding database indexes on frequently searched fields
-  - Caching strategies
+- Simple stored field with no computation overhead
+- Related field access is efficient in Odoo ORM
+- No additional queries needed for variant access
 
 ### Testing Strategy
 
 Tests cover:
 
-1. **Basic field storage** - Create supplierinfo with origin_text
-2. **Computed field** - Verify product shows main vendor's origin
-3. **Main vendor change** - Verify origin updates when main vendor changes
-4. **Translation** - Verify field is translatable (multilingual support)
-5. **Empty cases** - Product without vendors, vendor without origin
-
-### Future Improvements
-
-Potential enhancements:
-
-- Add migration script from `product_origin` to convert country/state to text
-- Add bulk update wizard to set origin for multiple products
-- Add origin text to purchase order lines
-- Add search/group by origin in product lists
-- Add validation rules (max length, format checks)
+1. **Basic field storage** - Set origin on template
+2. **Related field access** - Verify variant sees template origin
+3. **Write from variant** - Verify changes propagate to template
+4. **Empty cases** - Products without origin
+5. **Multiple products** - Independent origins
+6. **Variants** - All variants share same origin
 
 ## Code Quality
 
 - Follows OCA guidelines
 - Black formatted (line length 88)
-- isort sorted imports
-- Passes flake8 and pylint checks
-- Full test coverage
-- Documented with docstrings
-- Translatable strings handled correctly (no `_()` in field definitions)
+- isort for imports
+- Minimal dependencies (only `product`)
+
+## Migration from v1.x
+
+If upgrading from the previous supplier-based architecture:
+
+1. Data in `product.supplierinfo.origin_text` will need manual migration
+2. Run migration script to copy main supplier origin to product template
+3. Remove dependency on `product_main_seller` if no longer needed
 
 ## Version History
 
-- **18.0.1.0.0** (2026-02-25) - Initial release
+- **18.0.2.0.0** (2026-03-06) - Simplified architecture
+  - Field directly on product.template
+  - Related field in product.product
+  - Removed dependency on product_main_seller
+
+- **18.0.1.0.0** (2026-02-25) - Initial release (deprecated)
   - Free-text origin field per supplier
   - Automatic display based on main vendor
-  - Multi-language support
-  - Full test coverage
-  - OCA documentation structure
