Renovate PR Review Results

⚖️ Safety Assessment: ✅ Safe

🔍 Release Content Analysis

• Bug fixes only: TypeScript 5.9.3 is a patch release containing only bug fixes, no new features or breaking changes
• Key fixes: Fixed project reference handling, declaration file generation issues, and parenthesizer rules
• Regression fixes: Addressed private fields appearing incorrectly in type literals and ignored declaration files
• No security fixes: No security-related vulnerabilities were addressed in this patch

🎯 Impact Scope Investigation

• TypeScript usage: Used only as a dev dependency for compilation, not runtime dependency
• Build process: Project uses Bun's built-in bundler (tasks/build.ts) rather than TypeScript compiler directly
• Type definitions: Simple custom type declarations in src/types/index.d.ts for external modules
• No runtime impact: Since TypeScript only affects development/build time, no runtime behavior changes
• Compatible configuration: Existing tsconfig.json is compatible with TypeScript 5.9.x features
• No DOM/Buffer usage: Codebase doesn't use ArrayBuffer or TypedArray types that could be affected by DOM library changes

💡 Recommended Actions

• Safe to merge: This is a routine patch update with minimal risk
• No code changes required: The bug fixes in 5.9.3 improve stability without requiring code modifications
• Consider running build: Although not required for review, a successful build would confirm compatibility
• Monitor future updates: Watch for TypeScript 6.0 transition mentioned in release notes
