// Retry wrapper around `prisma generate`. Our two prisma clients pin the same

|
|
// `turbo run generate` runs them concurrently both race to write the shared
|
|
// query-engine binary, and on Windows the loser fails with `EPERM ... rename`.
|
|
// Retrying lets it succeed once the engine file is present and unlocked. On
|
|
// non-Windows the first attempt succeeds, so this is a zero-cost no-op.
