# Scenario 09: Ambiguous symbol resolution
# Question: "Where is 'validate' defined — and which one do callers mean?"
#
# Tests: search + refs for a symbol that exists in 4+ files
# Key differentiator: cartog returns distinct symbols with file locations;
# grep returns a wall of matches across definitions AND usages.
