- keep the init entry point at virtual address zero
- disable RISC-V small-data gp assumptions in user programs
- enlarge kernel stacks and use a finite safe libctest subset
- execute finite BusyBox cases and report their real exit status
- shut down RV through SBI SRST after all selected groups
- shut down the minimal LA QEMU target through ACPI GED S5
- remove references to another team from repository documents

Human-Reviewed: required before competition submission
Test: official Docker make clean && make all
Test: platform-form LoongArch QEMU command exits with status 0
Test: RV regression completes both basic groups and 34 selected libctest passes without the prior panic
