Abstract: The disclosed technology teaches rejecting, during validation, a sequence of components intended for interacting with a user. Included are providing a sequence setup GUI supporting construction of an executable sequence by connecting at least five components in a directed graph, and tracing multiple paths through the directed graph, including from at least one conditional branch at a first up-chain component, in which down-chain components accept as input and depend on output from at least one up-chain component, referred to as input chain dependencies. Also included are locating at least one error in use of a particular down-chain component when invoked following one of the multiple paths, where the error results from failure to satisfy any of the input chain dependencies of the particular down-chain component, and reporting the error during validation to a user of the GUI, before passing the sequence of components from validation to use in production.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for protecting user privacy in the playback of user sessions are described. In one aspect, a method includes accessing, for a user session with one or more user interfaces, event data that includes interface data specifying a structure of the user interface(s), and, for each of one or more user interface elements for which content was presented by the user interface(s) during the user session, an encrypted content element including the content of the user interface element encrypted using a public key corresponding to a rule enabling recording of the content of the user interface element and data identifying the rule. Playback of the user session is generated including, for each of the interface element(s), decrypting the encrypted content element for the user interface element and presenting the decrypted content during the playback of the user session.
