@Emmyt24 has applied to work on this issue as part of the Stellar Wave Program's 1st wave.

I’d like to take on this task. I’ll complete the missing Definition::Constant, Definition::ExternalFunction, and Definition::Module branches in core/type checker/src/symbol_table.rs, ensuring symbols are correctly registered with proper scope, visibility, and diagnostics. I’ll align the implementation with the existing parser_context changes and add validation to prevent duplicate or invalid symbol definitions.

Hello maintainers 👋

I’ve reviewed this issue and the relevant parts of the codebase. I’m a junior full-stack developer with hands-on experience contributing to real-world open source projects across both Web2 and Web3 contexts. My work includes JavaScript/TypeScript-based stacks, React on the frontend, Node.js on the backend, as well as contributing to blockchain-related repositories, including smart contract logic and protocol-level features.

I’m comfortable reading and understanding existing codebases, reasoning about on-chain and off-chain interactions, and delivering clean, focused implementations aligned with the project’s conventions. I’m used to working through GitHub workflows, iterating based on feedback, and prioritizing maintainability and clarity.

This issue aligns well with my experience, and I believe I can provide a solid and reliable solution. If it’s still available, I’d be happy to take it.
