Month 2025-10 summary for babylon (repo: babylonlabs-io/babylon). Focused on stabilizing co-staking and finality provider flows. Delivered deterministic co-staking by sorting distribution information to remove non-determinism; extended the jailing test scenario to cover co-staking; and implemented sorting of newly active/inactive finality providers by BTC public key to improve reliability and predictability of co-staking and finality provider management. Impact: Reduced non-deterministic behavior, increased test coverage, and improved production stability for staking and provider management. This work directly enhances user trust in validator selection, staking rewards distribution, and system reliability under churn. Technologies/skills demonstrated: deterministic algorithms (sorting), test automation and scenario expansion, cryptographic key ordering for stable provider selection, and robust commit traceability (commit b7266ea971430471b9d2d2c4bb9f9892b4af3eec).
