# Verification script for startup wedge fix (bf-2u1)
#
# This script verifies that the fix for the startup wedge issue works correctly.
# The wedge occurred when child claude inherited global settings that contained
# hooks (SessionStart, etc.) which could cause hangs at startup.
#
# Fix: Always pass --setting-sources= when launching with custom settings.json
