# Usage:
#   docker compose -f docker-compose.test.yml up --build --exit-code-from test-runner
#
# The test-runner service replaces the demo coordinator: it runs pytest against
# the live CLN stack and exits 0 on success, 1 on failure.
#
# CLN nodes wipe their regtest/ database on every container start so the stack
# is always in a clean, consistent state regardless of previous runs.
# Bitcoind keeps its blockchain (persistent volume) so blocks aren't re-mined.
#
# NOTE: the elementsproject/lightningd image has an entrypoint script that
# calls `lightningd --network=... "$@"`.  We override the entrypoint with
# ["sh", "-c"] so we can wipe stale state before starting lightningd.

  # Each CLN node wipes its regtest/ subdirectory on startup so it always starts
  # from block 0, matching bitcoind even if the volume carried stale state.
