# DR-0020 fine-tune environment (SEPARATE venv on the GPU machine / Colab —
# these never enter the project's own dependencies).
#
# Colab: `pip install unsloth` usually suffices (it pins its own torch/
# transformers/bitsandbytes). Local RTX 5060 (Blackwell): install a torch
# build matching your CUDA first, then unsloth; if bitsandbytes 4-bit kernels
# misbehave on the new consumer arch, fall back to the free T4 — that PoC path
# is first-class, not a downgrade (DR-0004 / DR-0008 spike precedent).
#
# Re-verify versions at kickoff (DR-0020 §9): the Unsloth template-mirror and
# export behaviours referenced in train.py were checked against upstream on
# 2026-07-02.
