Systems and methods for mobile peer-to-peer content sharing

A system for governing digital communications, comprising:

• a processing device comprising registers and arithmetic logic units;
• non-transitory computer readable storage medium storing computer-executable instructions that, in response to execution by the processing device, cause the processing device to perform operations, comprising:
• establish a relationship object representing a trust relationship between communicating parties;
• generate relationship-scoped validation material associated with the relationship object;
• maintain a trust ledger configured to store event-driven, non-identity metadata associated with the relationship;
• maintain a relationship state model defining a plurality of relationship states and permitted communication behavior associated with respective states;
• and
• instantiate a communication validation component configured to:
• receive, prior to delivery or presentation, a communication associated with the relationship object;
• evaluate the communication using the relationship-scoped validation material and expected continuity data derived from the trust ledger;
• and
• deterministically accept, reject, or restrict the communication based at least in part on the relationship state and continuity evaluation,
• wherein communication handling is performed at run-time independently of identity authentication, shared secrets, or
• probabilistic threat scoring.
