#!/bin/bash

# Runs the device test plan with Claude Code on this runner after the smoke test, one session per layout,
# as claude-scope says. A session drives the app only through the ui helper, and reads and writes only its
# own directory <output dir>/<layout>: prompt.md, report.md, shots/, transcript.jsonl (stream-json).
# Usage: scripts/ci/ios-sim/claude-test.sh <output dir>
# Needs CLAUDE_CODE_OAUTH_TOKEN, SIM_UDID (the booted simulator with the app) and, when the test backend runs, BACKEND_DIR.
