+"""Shared-field-ownership declarations for account.move.
+
+Per the roadmap (Section 3.3), these fields exist in Odoo Enterprise's
+account_accountant module. By declaring them here with identical schemas
+and identical relation tables, fusion_accounting_core becomes a co-owner.
+When Enterprise uninstalls, Odoo's module registry sees fusion still owns
+the fields and preserves the columns / relation tables, so the data
+(deferred revenue links, signing user, etc.) survives uninstall.
+
+The fields here have NO compute methods, NO defaults beyond what Enterprise
+provides, NO views. They're pure schema-preservation declarations. Any
+business logic that operates on these fields lives in Enterprise (when
+present) or in a future fusion sub-module that opts to own that behavior.
