+  # highs-sys has been flaky (CMake Threads::Threads target unavailable in
+  # the WASI sysroot — see v0.10.0 release run 25966236046). Until that
+  # upstream issue is resolved (tracked separately), this job must NOT
+  # block `create-release` from publishing the binaries that DID build.
+  # Test evidence is a desirable add-on, not a required gate; cargo test
+  # already ran on the merge commit before the tag was pushed.
