The encoder child is CPU only (GPU placement, GpuBusy and plan_placement
are deleted) and assembles LLM2Vec B: Llama base, MNTP merged, then the
supervised adapter. The cache identity names assembly, device, dtype,
torch/transformers/peft/accelerate versions, Kimodo commit and the child's
own sha256 beside the three revisions. VILI_THREADS (1..16) caps torch in
the worker and the child. The worker binds port 0 and reports it in its
ready line; errors name a class and place, never the request.
