The A2O core was a follow-on to A2I, written in Verilog, and supported a lower thread count than A2I, but higher performance per thread, using out-of-order execution (register renaming, reservation stations, completion buffer) and a store queue. It is now being updated for compliancy and integration into open projects.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 18 stars here means stars gained during the window, not the repo's star count.
