The repo was committed from WSL with core.filemode=false, so the exec bit was never recorded. After actions/checkout the entry script comes down as 100644 and tests/test_cli.sh fails with Permission denied. Set mode 100755 on every script that is invoked directly (entry, installer, test suite, mock binaries). Sourced helpers under lib/ keep 100644 per convention.
