Hi, I'd love to work on this.

My background includes merged GrantFox PRs across Core-Foundry, Flux-DeFi, StellarLend, and aid-linkk. I'm comfortable across Rust/Soroban, TypeScript, and backend stacks.

Process:

1. Clone and review the relevant code paths
2. Implement clean, minimal changes
3. Test thoroughly and open a PR

I'm ready to begin now.

I'd like to take ownership of this issue. I've reviewed the requirements and have a clear approach for implementing a robust, scalable, and maintainable solution that satisfies all acceptance criteria.
