Check the ARM/Thumb success marker with the runner-provided grep -F. The real Ghidra probe succeeded, but the previous rg dependency made the lane exit 127. Validated with the actual workflow shell, producer-failure and missing/incorrect marker controls, 17 focused tests, and hosted Ghidra 12.1.4 / JDK 21 compilation and ARM/Thumb context checks.
