      # SOURCE_COMMIT is intentionally not declared here. Coolify provides it
      # at runtime via its generated env file; declaring it here with Compose
      # interpolation can override the runtime value with an empty string.
      # Storage auto-selects mongodb because MONGO_URL is set — no KV_PROVIDER.
      # The in-process cron scheduler runs by default — no CRON_MODE.
      # PORT defaults to 8080 (internal health server) — omit unless overriding.
      # Long polling = no TELEGRAM_WEBHOOK_SECRET, no /webhook, no public domain.
      # Cron is in-process only — there is no /cron HTTP route and no secret.
      # No stock/coin/gold URL env overrides — modules use their coded default
      # providers (stock: SSI/VCI/KBS; coin: Binance->Coinbase->CoinGecko;
      # gold: VNAppMob). If GOLD_VNAPP_API_KEY is unset, the bot auto-fetches
      # and caches a key to Mongo.
    # Long polling is outbound-only: nothing inbound to route, so no published
    # ports and no public domain. `expose` keeps :8080 reachable inside the
    # Coolify network for the container health monitor against GET / only.
    expose:
      - "8080"
    # No compose healthcheck: distroless has no shell/curl and cmd/server has no
    # -healthcheck flag. Configure Coolify's HTTP monitor against GET / instead
    # (returns text/plain "miti99bot ok"). Note: a plain / check does not verify
    # Mongo connectivity — see docs/deploy-coolify-selfhosted.md.
