# ==============================================
# Matrix Dev Environment (Synapse + Element Web)
# ==============================================
#
# Development-only overlay for testing the Matrix bridge locally.
# NOT for production — use docker-compose.sample.matrix.yml for production.
#
# Usage:
#   docker compose -f docker/docker-compose.yml -f docker/docker-compose.matrix.yml up -d
#
# Or with Makefile:
#   make matrix-up
#
# This overlay:
#   - Adds Synapse homeserver (localhost:8008) using shared PostgreSQL
#   - Adds Element Web client (localhost:8501)
#   - Creates a separate 'synapse' database in the shared PostgreSQL instance
#   - Enables open registration for easy dev testing
#
# After first startup, create the bot account:
#   docker/matrix/scripts/setup-bot.sh
#

  # Synapse Database Init
  # ======================
  # Creates the 'synapse' database and user in the shared PostgreSQL instance.
  # Runs once and exits — idempotent, safe to run repeatedly.
