Key findings from full source audit:
- gen_patch.py's VLLM_INJECTION_POINTS target csrc/*.cu files that DON'T EXIST
in EngineX (precompiled .so, no CUDA source). This is why it outputs 0 patches.
- Actual injection is via patch_ops.sh full-file Python replacements (15 files)
- Python-side tuning values (_PARTITION_SIZE=512, SMEM=49152, Q_CHUNK=256) are
hardcoded in deployed files, not programmatically derived from muh headers
- 27 muh headers have 36+ bi100_* structs (14 reduce, 22 scan) all SMEM-safe
- scale_mem_bound passes all 4 CCCL parity tests
- Benchmark infrastructure (bench_bi100.py) ready but needs BI-V100 hardware
This replaces the stale GROUND_TRUTH_STATUS.md and GROUND_TRUTH_STATUS_v2.md.
