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.

Hello Maintainer. I'm interested in this issue because it involves investigating a correctness bug, identifying the root cause of the notification count mismatch, and ensuring consistent state across the application. I have experience debugging backend logic, fixing synchronization issues, and adding comprehensive test coverage to validate edge cases and prevent regressions.
