# DigitalOcean App Platform spec — one-click deploy.
#
# Click the badge in the README, or run:
#   doctl apps create --spec .do/app.yaml
#
# After the app comes up, mint your first bearer token from the App console
# or via doctl:
#   doctl apps list                          # find your app id
#   doctl apps exec <app-id> server \
#       -- ./flashback token mint --user=admin --name=initial
#
# The MCP URL is then https://<app>.ondigitalocean.app/mcp with the bearer
# pasted into your Claude Desktop / Cursor / Claude Code config.

  # AUTO_MIGRATE=1 so the first boot creates the schema.
