# One README repo, WITH-codegraph only, N runs. Each run appends a why-Read
# diagnostic so the agent explains any Read/Grep. (The WITHOUT baseline is
# codegraph-independent and already in the README — no point re-running it.)
# Output -> /tmp/ab-why/<repo>/with<n>.jsonl
# Usage: bench-why-repo.sh <repo-path> "<query>" [N]
