Topology (local parity = production)

services:
  sqlserver:   # gtp-sqlserver on 14333:1433, volume mssql_data
  postgres:    # gtp-postgres on 5433:5432, volume pg_data
  redis:       # gtp-redis on 6380:6379
  api:         # build backend/, ASPNETCORE_URLS=http://+:8080, ports 8080:8080, depends_on sqlserver+redis
  mcp:         # build mcp/, Streamable HTTP on 3001:3001
volumes: { mssql_data:, pg_data: }

Rules

• Daemons prefixed gtp-*; never collide with a personal stack's ports.
• Secrets via env (.env, git-ignored); no hardcoded passwords.
• Named volumes, no host-path binds for data.
• Health checks for api and sqlserver.
