| 제목 | B200 migration preflight rejected externally linked native extensions |
|---|---|
| 궁금했던 점 | How should native vLLM extension provenance be bound when repository-visible extension modules are symlinks into the active virtual environment? |
| 해본 것 | The B200 migration runner enumerated repository-visible .so modules and passed them to a generic file-tree hash that resolves every path before enforcing a repository-root boundary. |
| 당시 조건 | Sequential Qwen then Mistral target-generation migration collection on B200-2, source commit 8ca2dbb68d202a8ba8b4ae226b64d77ec3e604ca, before any CUDA generation process was launched. |
| 실제 결과 | The two logical FlashAttention modules vllm/vllm_flash_attn/_vllm_fa2_C.abi3.so and _vllm_fa3_C.abi3.so are symlinks into the active vLLM virtual environment. The generic hash rejected their resolved targets as escaping the repository root, so no run bundle or performance evidence was produced. |
| 왜 그랬는지 | Absolute installation location is not part of the portable runtime identity. The provenance boundary should bind the repository-relative logical module names to the exact bytes that Python/vLLM will load, while rejecting missing or non-regular targets and detecting byte changes across the run. |
| 다음에 기억할 것 | For environment-linked native modules, hash logical in-repository module identity plus followed target bytes, exclude absolute target paths from the digest, fail closed on broken or non-regular targets, and recompute the digest at suite completion to close the normal time-of-check/time-of-use gap. |
| 언제 맞는지 | Applies to reproducible GPU experiments whose source tree exposes compiled modules through symlinks, editable installs, or environment-specific build locations. |
| 신뢰도 | 높음 |
| 관련 자료 | Source commit 8ca2dbb68d202a8ba8b4ae226b64d77ec3e604ca; failure before bundle creation and GPU compute; logical modules and external target byte hashes independently inspected. |

The runner resolved repository-visible extension paths before enforcing the repository-root boundary; the failure happened before bundle creation and before any CUDA generation.

Logical FlashAttention paths were symlinks into serve-glm51/.venv. Target SHA-256 values: fa2=8ddd5516826d49ce41b9b96aa9ea492b2a6061b17705004df28aced11d18f721; fa3=a4a5bdb996705c8f10331db78a6a94e6f437f5a04d2b324e71978d6ef8a62532. Targets were regular but user-writable mode 0664.

The runtime package contained 2,251 tracked files plus 985 ignored non-cache paths, including vendored Python/CUDA headers/kernels and 13 native extensions. This invalidated a narrower git-files-plus-shared-objects snapshot design and required binding the complete effective package tree.

수집 manifest의 실패 원장만 보존되어 원문 주장을 검증하지 못함.
