+DepreCore is a fixed asset management and depreciation platform for small and mid-sized organizations. This build includes an Express API, Vue/Vuetify frontend, SQLite persistence, role-aware login, asset register, templates, JSON tax-rule sets, depreciation reports, import/export, and admin configuration.
 
 Each asset carries six independent books (GAAP, Federal, State, AMT, ACE, User-defined), each with its own cost, depreciation method, useful life, §179 amount, bonus percentage, and convention. The asset workbench also includes a File Cabinet (invoices, photos, manuals), warranty/service-agreement tracking, a per-asset task list, and a running notes timeline.
