# One run: fresh work copy + pack fixtures, the driver (worker turns + PO), then finalize.
# Usage: [TASK=F1|F2] run.sh <cfg> <rep>        cfg: bare|sp|spd|mp|both
#   RUN_TAG=x -> runs/<name>-x (smoke runs; analyze.py ignores tagged runs)
# The work copy lives OUTSIDE the repo tree ($FLOW_BENCH_WORK, default /private/tmp/flow-bench/<name>): Claude Code
# loads every CLAUDE.md of the parent directories, so a work copy under this repo read the repo's CLAUDE.md (and the
# instructions it pulls in) in every session. After finalize the copy (without node_modules) is archived to work/<name>.
