May 2025 performance summary for planetarium/NineChronicles.Headless: - Key features delivered: - GraphQL Block Starting Nonces Query: adds a new GraphQL query to retrieve starting nonces per signer for a given block, with a new data type and support for block lookup by hash or index. Commits: 4373876466cd6ad46ffba13aac3f5ada754ff337; 541c2d7a6c13c918016f9eb18cd5547a6044d4bd (fix); d12e01080f7d36dcff18a6c0149a9dfe0d4e1d34 (test). - Chain Block Commit Handling: improves chain integrity by correctly handling block commits during chain operations, introduces GetChainBlockCommit, and updates tests to reflect block commit behavior after truncation. Commits: 52394f191eecaa127458c5e3f5f5d541feba9fbd; 6c0382b14b12c76794efb21992ba04ae5baf31bc; dadaceece873bca63b755f12bee3b13b8851a975; d81233bb2c6354802ba6fcae6dd1d69c382aaa94. - Major bugs fixed: - Off-by-one error in nonce query resolved (nonce query now returns correct starting nonces). Commit: 541c2d7a6c13c918016f9eb18cd5547a6044d4bd. - Truncation and block commit handling corrected to use LastCommit as BlockCommit, with tests updated accordingly. Commits: 52394f191eecaa127458c5e3f5f5d541feba9fbd; 6c0382b14b12c76794efb21992ba04ae5baf31bc; dadaceece873bca63b755f12bee3b13b8851a975; d81233bb2c6354802ba6fcae6dd1d69c382aaa94. - Overall impact and accomplishments: - Strengthened chain integrity and reliability of block operations, reducing risk of incorrect signer nonces and data inconsistencies after truncation or reorgs. - Expanded GraphQL API surface with a robust, multi-identifier block lookup, enabling faster diagnostics and richer tooling. - Expanded test coverage to reflect new behaviors, improving long-term maintainability and confidence in future changes. - Technologies/skills demonstrated: - GraphQL API design and type evolution - Data modeling for signer nonces - Robust testing and test-driven adjustments for truncation/commit flows - Code hygiene and commit discipline across features and fixes

Concise monthly summary for April 2025 focusing on the planetarium/lib9c pledge workflow improvements and associated test coverage.

February 2025 monthly summary focusing on delivering core features, stabilizing currency exchange flows, enabling network governance migrations, and preparing for the next release across lib9c and NineChronicles.Headless. Emphasis on business value through reliability, scalability, and operational readiness.

January 2025 monthly work summary for planetarium projects. Delivered a staking model overhaul in lib9c, comprehensive code maintenance, swap system enhancements, and expanded data exposure via RPC/GraphQL. Focused on business value: enabling validator participation, cleaner undelegation flows, improved data visibility, and stabilized builds/tests to accelerate development across two repositories (planetarium/lib9c and planetarium/NineChronicles.Headless).

December 2024 monthly summary focused on stabilizing and extending the RewardBase framework, delivering core API foundations, improving reward/unbonding flows, and expanding cross-repo tooling. The work emphasizes business value through reliability, security, and developer productivity, with strong testing and documentation to support maintainability and future evolution.

November 2024 monthly summary: Strengthened migration reliability, expanded GraphQL reach, stabilized staking/state semantics, and maintained release readiness across three repos. Key outcomes include deterministic GQL migration handling, richer validator and delegation workflows, expanded admin/refund capabilities, and proactive dependency updates. Business impact centers on safer migrations, more configurable rewards, improved front-end interactions, and smoother releases.

Month 2024-10 — Planetarium/lib9c: Delivered a consolidated Guild Migration Feature to streamline cross-guild and delegations migrations, with unbonding flow adjustments, accompanying tests and benchmarks. Implemented migration-specific tests, updated benchmarks, and prepared the unbonding process for migration. To keep rollout momentum, temporarily skipped failing tests during migration while the suite was stabilized and refactored for migration scenarios.
