Run the upstream toml-test conformance suite against the built decoder. DECODER=./toml-decoder sh sources/run_conformance.sh -run 'valid/string/*' # one group DECODER=./toml-decoder sh sources/run_conformance.sh -json # machine-readable DECODER decoder command. Required — this harness is language-neutral and deliberately has no default implementation language. TOML_TEST absolute path to the toml-test binary (default: found on PATH) The suite's identity is part of the verdict. Exit code is the harness exit code: 0 only when every test passes.
