ember-classic-decorator

A dev-time only decorator to aid migrating from Ember's classic class system to native classes in Ember Octane. The @classic decorator flags classes that still rely on classic APIs (reopen, reopenClass) and prevents timing bugs with init/constructor. Version 4.0.0 is the latest stable, requires ember-source >= 4.0.0. It is no longer needed and can be safely removed; it must be removed before switching to Vite. Ships TypeScript types. Low maintenance, intended for transitional use.
