#
# Lifecycle tests for the lnd package. Mirrors bitcoin-knots.bats so the
# 20× release-gate run exercises lnd through the same state matrix.
#
# Tiers:
#   - Read-only (always runs):        presence, state-reporting consistency, RPC reachable
#   - Destructive (ARCHY_ALLOW_DESTRUCTIVE=1): stop → start → restart
#   - Cascade-destructive (ARCHY_ALLOW_CASCADE_DESTRUCTIVE=1): uninstall → reinstall
#
# Pre-req: lnd is installed. Reinstall path is gated separately because it
# wipes the wallet macaroons and forces re-onboarding.
