Lessons Learned
summary
Windows file semantics and tooling force concrete changes: process creation is about 25,000 μs vs 2,500 μs on Unix, so the build removes bash from critical functions and rewrites the test wrapper as a native executable to avoid dozens of short-lived processes. External dependency handling proves brittle, so the project deprecates the built-in workspace rules and opens the include scanner and build event protocol while migrating rules to Starlark migration to reduce API surface and provide multi-release migration windows for incompatible changes.
