Contract: Add protocol-level risk limits for vault exposure

[Junirezz]

Summary

Limit how much exposure the vault can take under unsafe conditions.

Problem

The protocol needs explicit thresholds to reduce risk under volatility or strategy stress.

Acceptance Criteria

• Define hard caps for exposure or strategy concentration
• Validate that limits are enforced in contract logic
• Add tests for limit overrun and recovery
• Document thresholds and override conditions

I’d like to work on this issue because it addresses an important area of the project and presents a great opportunity to make a meaningful contribution. I’m particularly interested in delivering a solution that is reliable, maintainable, and aligned with the project’s existing architecture and development standards.

I have experience working across software development, including backend and frontend development, APIs, databases, testing, DevOps, and blockchain-based applications. I’m comfortable understanding existing codebases, identifying the root cause of issues, implementing clean and scalable solutions, and writing thorough tests to prevent regressions.

My approach would be to first understand the existing implementation and project conventions, then develop the solution in a focused and incremental way. I’ll ensure the changes are well-tested, documented where necessary, and do not introduce unnecessary complexity or break existing functionality. I’m also committed to clear communication, responding to review feedback, and delivering a polished contribution that provides real value to the project.
