"""Publish combined Phase-2 pack-measurement report (ADR-0043).

Runs both pack-driven runners (identity-divergence + refusal-calibration)
and writes a unified report to
`evals/results/phase2_pack_measurements.json` plus a per-runner copy
under each lane's own `results/packs_v1/` directory.

Usage:
    PYTHONPATH=. python3 scripts/publish_pack_measurements.py [--json]
