⚠️ Potential issue | 🟠 Major

Avoid silently removing unique CI coverage; gate these tests with an explicit temporary switch.

Line 55 and Line 56 currently remove the only L1 coverage for GRPO+Megatron+LoRA (including async), which means these paths won’t run in the main CI flow (.github/workflows/cicd-main.yml:310-327, plus main/scheduled L1 behavior in lines 100-120 of that workflow). Please keep these invocations in place behind an explicit skip flag and log the tracking PR/issue so re-enable criteria stays visible.

-# run_test      uv run --no-sync bash ./tests/functional/grpo_megatron_lora_async.sh
