GLM-4.7-Flash PIE C++ GRPO LoRA

LoRA rank-16 GRPO adapter for `zai-org/GLM-4.7-Flash`, trained with executable C++ correctness and performance rewards.

Verified H100 Run

The validation run completed successfully, logged 256 rollout samples and 125 evaluation samples, and produced a synchronized parameter update across all eight ranks. The before/after parameter hashes differ, all 16 synchronization records agree across ranks, and timing evidence is marked verified.
