#!/usr/bin/env bash
# Run every replay under tests/harness/replays/ against a fresh harness.
#
# Boots the harness (up.sh + seed.sh), runs each `replays/*.sh` in
# alphabetical order, tracks pass/fail, and tears down on exit. Returns
# non-zero if any replay failed.
#
# Usage:
#   ./run-all-replays.sh                # boot, run, teardown
#   KEEP_UP=1 ./run-all-replays.sh      # leave harness running on exit (debug)
#   REBUILD=1 ./run-all-replays.sh      # rebuild images before booting
#
# CI usage: invoke without flags. The trap-on-EXIT teardown ensures we
# don't leak Docker resources when a replay fails partway through.
