#!/usr/bin/env bash
# Run ONE ablation cell (build + eval) of the W4A8 SVDQuant grid, with its own logs.
# Invoked one-at-a-time by the operator (see saved feedback: no batched bg loops).

# Usage:  bash scripts/run_cell.sh <RANK> <variant> <WHITEN> <REFINE>
#   e.g.  bash scripts/run_cell.sh 16 plain          0 0
#         bash scripts/run_cell.sh 16 whiten         1 0
#         bash scripts/run_cell.sh 16 plain_refine   0 3
