# successful command path of the recorded agent run (see
# agent-run.transcript.md calls 15 and 20-21) in a fresh temporary directory:
# preview first, then apply, then check, balance and income statement.
# Inputs are the canonical challenge downloads; the rules are the agent's own
# rules.toml bytes, embedded verbatim. The full record, including the agent's
# exploratory reads and its one failed apply (sandboxed cache lock), lives in
# the transcript — this replay shows the working path only.
#
# Usage: sh demo-replay.sh   (needs `bea 0.1.0` on PATH)
