# tests/lifecycle/run-20x.sh — loop the lifecycle harness N times.
#
# Each iteration: setup-teardown → run.sh (with the same args you'd pass
# to run.sh) → setup-teardown. Tallies pass/fail per iteration and prints a
# summary at the end. Returns non-zero if any iteration failed.
#
# Env:
#   ARCHY_ITERATIONS                    (default: 20)
#   ARCHY_FAIL_FAST=1                   stop on first failed iteration
#   plus everything run.sh / lib/rpc.bash respects
#     (ARCHY_PASSWORD, ARCHY_HOST, ARCHY_SCHEME, ARCHY_ALLOW_DESTRUCTIVE,
#      ARCHY_ALLOW_CASCADE_DESTRUCTIVE, ARCHY_ALLOW_NOAUTH)
#
# Usage:
#   tests/lifecycle/run-20x.sh                       # 20× full bats/ suite
#   ARCHY_ITERATIONS=5 tests/lifecycle/run-20x.sh    # 5× full suite
#   tests/lifecycle/run-20x.sh bitcoin-knots          # 20× a single suite
#
# Suggested release-gate invocation:
#   ARCHY_PASSWORD=password123 ARCHY_ALLOW_DESTRUCTIVE=1 \
#     tests/lifecycle/run-20x.sh
