|title=<nowiki>B200 migration preflight rejected externally linked native extensions</nowiki>
|question=<nowiki>How should native vLLM extension provenance be bound when repository-visible extension modules are symlinks into the active virtual environment?</nowiki>
|attempt=<nowiki>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.</nowiki>
|context=<nowiki>Sequential Qwen then Mistral target-generation migration collection on B200-2, source commit 8ca2dbb68d202a8ba8b4ae226b64d77ec3e604ca, before any CUDA generation process was launched.</nowiki>
|observation=<nowiki>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.</nowiki>
|interpretation=<nowiki>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.</nowiki>
|reusable_lesson=<nowiki>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.</nowiki>
|applicability=<nowiki>Applies to reproducible GPU experiments whose source tree exposes compiled modules through symlinks, editable installs, or environment-specific build locations.</nowiki>
|confidence=<nowiki>high</nowiki>
|evidence=<nowiki>Source commit 8ca2dbb68d202a8ba8b4ae226b64d77ec3e604ca; failure before bundle creation and GPU compute; logical modules and external target byte hashes independently inspected.</nowiki>
