At git 8f61aa84212dc232a1392180fdbe4c0f8333d8fb, audited final_v1 protocol, run-plan inventory, generation/latency/trace validators, then ran a read-only B200-2 preflight with ssh -p 49001: GPU inventory/process query, git state, and .venv torch/CUDA/vLLM version checks.

B200 target-generation portability boundary The inventory declares target_generation::primary and target_generation::architecture_replication with hardware=null. Promotable generation validates pinned model/tokenizer, clean git, native extension hash, backend/runtime versions, and records the producing GPU, but does not bind the artifact to L40S or RTX. Latency, regime selection, native baseline, traces, policy bindings, host preflight, and results are target hardware/config bound. B200 final cells are rejected. Which pre-final artifacts can be completed on B200-2 and safely migrated to the L40S/RTX PRO 5000 final experiment? lab Complete only the two deterministic target-model generation calibrations on one isolated B200 GPU at a time. Preserve them as structurally promotable, content-addressed migration candidates; never treat B200 latency, throughput, load, policy, or comparative outcomes as final evidence.
