Mar 1, 2025March 2025 monthly summary for input-output-hk/partner-chains. Delivered a set of enhancements to release, test, and local environments, along with a critical bug fix that improves reliability of address association tests and substrate queries. The work strengthened business value by making releases more deterministic, expanding end-to-end test coverage, and streamlining developer workflows across local and staging deployments. Key outcomes: - More deterministic release cycles with reduced churn and clearer versioning flow. - Expanded, more robust end-to-end test infrastructure and per-worker logging to improve test reliability and debuggability. - Enhanced local development onboarding and workflow with fewer prompts and safer defaults. - Staging configuration alignment to reflect deployed state, reducing staging discrepancies. - Fixed a stake key hex-prefix bug to ensure correct address association even with leading zeros, preventing substrate query errors.

Feb 1, 2025February 2025 (Month: 2025-02) delivered key enhancements for Partner Chains development and testing. Major features include a wizard-based 3-node local deployment for Partner Chains with governance authority entrypoints, node roles, token config, and updated docker-compose/main scripts for local testing; plus an end-to-end address association feature linking partner-chain addresses to Cardano stake keys with signing, submission, and verification, accompanied by API docs. In parallel, end-to-end testing and CI/CD bottlenecks were addressed: stabilized test infra, improved Python/test environments and logging, and hardened staging for 1.5.0. Overall impact includes reduced local onboarding friction, faster feature validation, more reliable release pipelines, and better observability. Technologies demonstrated include Docker/docker-compose, scripting, sign/verify workflows, Python-based test automation, CI/CD tooling, and API documentation.

Nov 1, 2024November 2024 monthly summary for input-output-hk/partner-chains: This month delivered reliability-focused CI improvements and a critical bug fix. The CI workflow was updated to require all dependent jobs to pass before PR merges, enforcing checks in pre-merge and post-merge steps to block merges when critical checks fail, thereby increasing CI reliability and reducing flaky releases. In parallel, addressed an edge-case bug in committee participation probability where an empty registration list could be returned for SPOs with all invalid registrations. The calculation remains correct for T > 0; touched substrate_api.py and test_committee.py. Overall, these changes improved release stability, reduced post-merge hotfixes, and improved testing reproducibility. Technologies/skills demonstrated: Python, GitHub Actions, CI/CD, edge-case handling, and probability-based calculations. Business value: faster, safer code reviews and more predictable deployments.
