Since May 9, any package failing a reproducibility check is blocked from entering the testing branch, and packages already in testing that break reproducibility are also blocked. Reproducible builds ensure that compiling the same source code always produces the exact same binary, closing a security gap where malicious code could be injected at the build stage without touching the source. Currently 98.29% of architecture-independent packages in Forky pass the check, with 414 still flagged. This gives users a stronger guarantee that installed packages match published source code, and allows independent rebuilders to verify results. ## Full article daily.dev links to this article rather than hosting it.
