May 2026: Security-focused documentation update in cosmos/solidity-ibc-eureka. Added an IBC Attestation Replay Risk Warning to the design docs to mitigate replay risks stemming from attestor address reuse. This improves security posture, clarifies the attestation flow for implementers, and reduces deployment risk. No major bugs fixed this month.

February 2025 monthly summary for unionlabs/union: Implemented a targeted safety validation in misbehaviour processing by requiring distinct finalized headers in updates, preventing acceptance of reports that do not reflect a genuine divergence. This fix, tied to commit 00e222d89701f6a15eedabb738491dfe071fb44b, strengthens consensus safety and data integrity for cross-validator misbehaviour reporting. Overall impact: improved correctness, reduced risk of false positives in misbehaviour detection, and a clearer validation contract for future updates. This work demonstrates defensive validation logic, precise change traceability, and disciplined change management that aligns with repository standards.
