* Stabilize Windows frontend development startup Next.js Turbopack can infer a user-level workspace root and hit an internal Rust task panic on Windows. Keep the frontend root explicit and select Webpack on Windows while preserving Turbopack elsewhere. Constraint: The existing non-Windows development workflow should keep Turbopack. Rejected: Disable Turbopack on every platform | unnecessary performance regression. Confidence: high Scope-risk: narrow Reversibility: clean Directive: Revisit the Windows Webpack fallback after the upstream Turbopack panic is resolved. Tested: Prettier, ESLint, TypeScript, 139 frontend test files with 1060 tests, and Windows pnpm dev smoke test on port 3010. Not-tested: Production build and browser E2E suite. Related: #4957 * Make the frontend bundler fallback diagnosable Keep the Windows Webpack fallback while allowing local diagnosis to select either supported Next.js bundler. Resolve the Turbopack root through the Node 20-compatible URL API so the explicit workspace boundary remains effective across the declared Next.js engine range. Constraint: Windows defaults to Webpack because of the observed Turbopack panic, while non-Windows defaults to Turbopack. Rejected: Accept arbitrary bundler values | Next.js only supports the two explicit flags and invalid values should fail early. Confidence: high Scope-risk: narrow Reversibility: clean Directive: Revisit the default Windows fallback when the upstream TaskGuard issue is resolved; the override is intentionally retained for diagnosis. Tested: Frontend format, ESLint, TypeScript, 139-file/1062-test Rstest suite, target launcher tests, and next.config.js absolute-root load check. Not-tested: Production build and browser E2E suite.
