Greptile Summary

This PR claims to downgrade Next.js to fix Bun bundling compatibility issues, but actually upgrades Next.js from version ^15.3.2 to ^15.4.1. The changes add package overrides in both the root package.json and apps/sim/package.json to enforce specific versions of Next.js and @next/env across the entire dependency tree.

The key changes include:

• Moving Next.js version from ^15.3.2 to ^15.4.1 in both package files
• Adding overrides sections to force consistent versions across all workspace packages
• Moving @next/env from devDependencies to the overrides section in the root package.json

The overrides mechanism ensures all transitive dependencies use the specified versions, which can help resolve version conflicts. However, this contradicts the stated goal since upgrading to a newer Next.js version is unlikely to resolve compatibility issues with Bun that were present in the previous version.

PR Description Notes:

• The PR title says "downgrade nextjs" but the change is actually an upgrade
• The description claims incompatibility with "nextjs 15" but upgrades within the Next.js 15 series
• Testing section just repeats "downgrade nextjs" without specific test details

Confidence score: 1/5

• This PR has a fundamental contradiction between intent and implementation that could cause production issues
• Score reflects the mismatch between claimed downgrade and actual upgrade, which may not resolve the stated Bun compatibility issues
• Both package.json files require immediate attention to verify the correct Next.js version needed for Bun compatibility

logic: Version changed from ^15.3.2 to ^15.4.1 - this is an upgrade, not a downgrade as claimed in PR title/description

[greptile-apps]

logic: This upgrades Next.js from 15.3.2 to 15.4.1, contradicting the PR title claiming a 'downgrade'. If Bun has compatibility issues with Next.js 15, upgrading to a newer 15.x version may not resolve the problem.
