ORM: - ExtendModel(name) retrieves existing model for extension (mirrors Python _inherit without _name). Panics on missing model. - RegisterInverse(fieldName, fn) convenience for computed write-back - Inverse field handling in Write(): caches new value, calls inverse method so computed fields can be written back Sale module: - Extends res.partner with sale_order_ids (O2M) and sale_order_count (computed) via ExtendModel — demonstrates real _inherit pattern Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
