제목	Complete private vLLM snapshots make B200 generation provenance portable
궁금했던 점	How can a B200 generation collector use ignored precompiled vLLM payloads and external native symlinks without leaving mutable runtime dependencies?
해본 것	Materialize the complete effective vLLM package before GPU work: exact-commit tracked files, every non-bytecode ignored runtime file, and stable-copied direct symlink target bytes. Freeze it read-only, launch with Python safe-path and a private PYTHONPATH, disable plugins, reject inherited VLLM overrides, and rehash before and after each model.
당시 조건	Three-policy pivot target-generation migration collector, source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369, intended for sequential Qwen then Mistral collection on B200-2.
실제 결과	A real CPU-only materialization covered 3,236 files and 553,835,742 bytes: 2,251 tracked files, 985 runtime-untracked files, 13 native extensions, and 2 direct symlinks materialized as regular files. Strict audit validation and actual vLLM package import from the private snapshot passed, and teardown left no snapshot files.
왜 그랬는지	The portable runtime identity is the sorted logical package paths plus sizes and content hashes, not editable-install metadata or absolute target locations. The complete package digest must travel in generation backend provenance alongside the native-only digest.
다음에 기억할 것	For editable or precompiled ML runtimes, snapshot the entire effective package rather than only Git files or shared objects; reject inherited behavior controls, prove actual import origin, content-bind both package and native subsets, and retain a strict sanitized audit with the result.
언제 맞는지	Applies to reproducible GPU inference experiments using editable installs, ignored wheel payloads, JIT caches, external symlinks, or plugin entry points.

The complete private-package snapshot replaces the rejected direct external-symlink hashing approach and closes the normal multi-model mutation window.
