Testing is a broader term covering multiple things, up to and including the decision of when you have enough confidence in the system to declare it stable. The test pass rate was an early bar for merging into dev, not release.

The translation did not change the architecture: it was a 1:1 translation with even the same internal data structures. Rust written in a zig-like way, with the original Zig still available as reference. AI can make an absolute mess when making architectural decisions, but translation like this plays to the strength of current AI, especially when moving to a stricter language.

The code being in the dev branch means that they now are open to community feedback and testing, and no date is set on it being declared stable. We'll see how the team handles it.
