# ONE offload run on ONE indexed repo at a given offload STYLE (plain|refs), so we can
# watch a single agent transcript at a time (the user's one-run-at-a-time methodology).
# The OFFLOAD reasoning runs in the prewarmed DAEMON process, so the style env must be
# set on BOTH the daemon and the client MCP config. Writes one metrics line to RESULTS
# and leaves the raw stream-json at $RUNS/<repo>-<style>-<n>.jsonl for inspection.
#
# Usage: offload-eval-refs1.sh <indexed-repo> <style> <n> "<question>"
