Contributor guide
Research direction
Start by running `bazel test -c opt //xls/fuzzer:run_crasher_test_2026-06-22_ea6c.x` and inspect `sample.ir` at the `JoinVals::computeAssignment` crash. Confirm the reproducer and trace the SIGSEGV to its compiler entry point; done means the crasher test completes without the segmentation fault.
