2025-09 monthly summary for propeller-heads/tycho-protocol-sdk. Delivered Protocol Testing SDK Enhancements enabling dynamic adapter loading and RPC-based transaction simulation against historical blockchain states. Notable commits include 93b969e41f20016c2fffc0d3e5e61f6bc6095ea6 (Pass adapter path to decoder) and eaca47479b906116c7f999f7da53fe247b9c9356 (Simulate txs against RPC). The work added runtime adapter resolution via DecoderContext, test runner improvements (VM and execution trace support), state overrides, gas calculations, and integration with signature databases for trace analysis. Major bugs fixed: None reported this month; minor stability improvements addressed as part of这些 enhancements. Business value: improved test fidelity, reproducibility, and observability, accelerating validation of protocol changes and reducing deployment risk. Technologies/skills demonstrated: dynamic adapter loading, RPC-based testing, VM/execution tracing, state overrides, gas modeling, and trace analysis.

August 2025: Stabilized the Tycho Protocol SDK testing environment by fixing the Docker-based CI/testing stack. Implemented corrections to docker-compose.yaml environment variables and enhanced the Dockerfile to include essential build tools and PostgreSQL extensions (pg_cron, pg_partman) so tests run consistently across environments.

May 2025 for propeller-heads/tycho-simulation focused on stabilizing protocol handling in the VM layer. Delivered a targeted bug fix to Maverick v2 protocol identification, reinforcing reliable VM handshake and protocol detection in simulation scenarios. The change reduces misdetection risk and supports smoother Maverick v2 deployments.
