# start_canopy_testnet.sh — Launch a clean, isolated Canopy testnet instance
#
# Runs on port 7780 (web) with its own fresh database and NO P2P mesh.
# CANOPY_DISABLE_MESH=true means it never auto-joins the main instance or
# any other peer on the LAN.  Agents connect via HTTP API keys only.
#
# This does NOT touch or interfere with the main instance (7770).
#
# Usage:
#   ./start_canopy_testnet.sh           # start testnet (preserves existing DB)
#   ./start_canopy_testnet.sh --reset   # wipe DB and start completely fresh
