Implements a dependency graph data structure for resolving package dependencies with different node states (unresolved, resolved, failed). Provides traversal and marking functions that are completely self-contained with no external dependencies. Demonstrates skill in graph algorithms, TypeScript generics, and proper state management for dependency resolution scenarios.

Parses and validates package specifications (name@version) handling different version formats (semver, tags like 'latest'/'stable', and URLs). Features comprehensive validation with TypeScript type narrowing to ensure correctness. Could be extracted and used in any package management tool with minimal modification.

Provides atomic operations for adding/removing dependencies from Unity project manifests while maintaining scoped registries and testables. Handles edge cases like empty arrays and demonstrates immutable update patterns. The component is isolated and could be reused in other manifest-based systems with minimal changes.

Handles Unity project manifest (manifest.json) operations including parsing, serialization, dependency scoping, and testable management. Features proper handling of edge cases (empty arrays, missing properties) and immutable updates. The parsing/serialization logic is cleanly separated from business logic.

Provides type-safe equivalents of Object.entries and Object.keys that preserve key types through generics. Solves a common TypeScript problem when working with records/objects where key information is typically lost. Demonstrates advanced TypeScript techniques for maintaining type safety in utility functions.

Contains utilities for working with Zod schemas, particularly the removeExplicitUndefined function that recursively removes undefined values from objects. Solves a common problem with Zod where undefined values can cause validation issues. The utility is self-contained and could be applied to any project using Zod for schema validation.
