April 2026 performance summary for oxidecomputer/omicron: Focused on networking reliability, API clarity, and automation readiness. Delivered two major feature sets with concrete business value: (1) Enhanced networking: introduced a new service zone NAT entries type, integrated NAT entries into bootstore network configuration with real values derived from the RSS service plan or blueprint, and added an omdb command to display current network configuration for debugging and administration. (2) Bootstrap agent API refactor: removed legacy v1 and moved key types to a new lockstep crate (bootstrap-agent-lockstep-types) to improve API clarity and flexibility. Follow-up work populated the new NAT entries with real values during rack setup, tying configuration directly to RSS/Nexus workflows. Commit activity spans bootstore changes (#10218, #10219, #10225) and API cleanup (#10216). Closes: #9931, #10168. Impact and value: improves network provisioning reliability, reduces manual debugging, and enables automation-ready bootstrapping. The changes also simplify maintenance by consolidating lockstep API surface and decoupling legacy v1 code. Technologies and skills demonstrated: Rust crate management and refactor, bootstore integration, cross-crate type reorganization, and end-to-end tooling (omdb) with tests to cover new paths.
