All lint issues are fixed except a handful that are deferred pending future changes. --- > [!NOTE] > **Medium Risk** > Moderate risk due to new controller dependencies and changes to initialization wiring/typing that could affect runtime messaging and controller lifecycle. Test behavior now depends on external `INFURA_PROJECT_KEY` and mocked timers, which may introduce CI/environment sensitivity. > > **Overview** > **Stabilizes wallet builds/tests by wiring in missing controllers and config.** The wallet package now depends on additional controllers (accounts/approval/connectivity/network/remote feature flags/transaction) and updates TS project references accordingly. > > **Improves runtime/test ergonomics.** Jest loads a local `.env` (with `.env.example` added and `.env` gitignored), `Wallet` exposes stronger typed `messenger`/`state` and adds `destroy()` to clean up controller instances; tests are updated to require `INFURA_PROJECT_KEY`, use fake timers, and properly teardown the wallet. > > **Tightens initialization typing and controller wiring.** Adds `initialization/defaults.ts` for inferred `DefaultInstances`/`DefaultActions`/`DefaultEvents`, introduces `bindMessengerAction` to preserve action typings, and updates controller initializers (notably `TransactionController` and `RemoteFeatureFlagController`) to pass required options and bind messenger actions safely. > > Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit a6529337b2daf27d06b4a9e4645ab88939576880.
