"""Showcase tinymfv's plotting on a real steering run. Consumes a steering-lite `run_allinstr_showcase.py` output dir (one calibrated activation-steering vector administered across every instrument over a signed c-sweep) and renders the SAME two figures for every instrument, uniformly: - map : ipsative culture map (PCA), AI coherent +/-c path vs the human cloud. - range: per-factor range, AI base + coherent +/-c path vs the human society strip. Ordinal instruments read _profiles.csv. MFV reads mfv_profiles.csv and is projected into z-scored relative-emphasis space, because its nominal foundation probabilities cannot share a raw axis with 1-5 survey scores. It still goes through the same plot_ipsative_pca / plot_range functions. cs are SIGNED multipliers of the calibrated coefficient C (0 = base). The public README plots show the coherent path: c=0 plus each +/-c row whose tinymfv answer mass stays above the requested fraction of base. Incoherent rows are dropped. uv run python scripts/plot_steer_showcase.py \ --run-dir ../steering-lite/outputs/allinstr_qwen35_4b \ --out docs/img/showcase \ --vec-label "MFV Authority anchor (+c intended higher Authority)" """ from __future__ import annotations import argparse import copy import csv import json from pathlib import Path from types import SimpleNamespace import matplotlib matplotlib.use("Agg") import matplotlib.pyplot as plt import numpy as np import tinymfv as T from tinymfv import get_instrument from tinymfv.zones import zones_for # 16pf turned off: even at 6 macro zones its ipsative map is an unreadable pile-up (that instrument # doesn't separate cultures; Brazil/Ecuador stretch Latin America across the whole plot). -- Claude ORDINAL = ["mfq2", "big5", "humor_styles"] def _frac(x, scale_max: int) -> np.ndarray: return (np.asarray(x, float) - 1) / (scale_max - 1) def read_human_csv(path: str) -> dict[tuple[str, str], float]: """{(country, foundation): mean} from a tinymfv human_.csv.""" out: dict[tuple[str, str], float] = {} with open(path, newline="") as fh: for r in csv.DictReader(fh): out[(r["country"], r["foundation"])] = float(r["mean"]) return out def human_matrix(instr) -> tuple[list[str], np.ndarray]: """(countries, M[countries x factors] as 0-1 fraction).
