If it is, be clear in summary. - [x] Read through code myself one more time. - [x] Make sure any and all `TODO` comments left behind are meant to be left in. - [x] Has reasonable passing test coverage? - [ ] Updated changelog if applicable. - [ ] Updated documentation if applicable. --- ✨ Let Copilot coding agent [set things up for you](https://github.com/streamr-dev/network/issues/new?title=✨+Set+up+Copilot+instructions&body=Configure%20instructions%20for%20this%20repository%20as%20documented%20in%20%5BBest%20practices%20for%20Copilot%20coding%20agent%20in%20your%20repository%5D%28https://gh.io/copilot-coding-agent-tips%29%2E%0A%0A%3COnboard%20this%20repo%3E&assignees=copilot) — coding agent works faster and does higher quality work when set up for your repo. --- > [!NOTE] > Expands test coverage for `executeSafePromise` to validate error-handling in different runtimes. > > - Adds Node/Electron tests in `packages/utils/test/executeSafePromise.test.ts` to assert `process.exit(1)` is invoked on rejection and that exit is triggered after fatal errors > - Adds browser-environment tests by removing `process.exit` to assert a thrown error with message `executeSafePromise: Assertion failure!` and proper `cause` chaining > - Retains success-path test to confirm resolved value handling > > Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit ff0e81fde1b0d5b1e90aa45701d81f9cf6394875.
