# Production-ready partner-edge acceptance test.
# Asserts that after install.sh completes, the edge has:
#  1. All compose services up for which credentials/config are provided
#  2. Caddy upstream pool contains every active channel
#  3. channels-status.env reflects actual runtime state
#  4. /metrics endpoint reachable (Phase 5.8)
#  5. Telegram alert delivery wired (Phase 5.8)
#  6. Naive deployed when NAIVE_SERVER set (Phase 5.10)

# Driven by: docs/superpowers/plans/2026-05-19-production-ready-installer-multi-channel.md
