Usage: $0 --target-id ID --schema NAME [options]

Required:

  --schema NAME            Schema/database to harvest

Optional:
  --mcp-config PATH        Claude Code MCP config (default: ${SCRIPT_DIR}/mcp_config.json)

  --notes TEXT             Notes for static harvest (default: ${NOTES})
  --endpoint URL           MCP query endpoint (default: ${ENDPOINT})
  --skip-phase-a           Skip static harvest and use --run-id
  --run-id N               Existing run_id (required when --skip-phase-a)
