Ticket, proposal, and WebSocket revisions now fail closed unless they are finite, non-negative integers; fractional values are no longer silently truncated into valid revisions. Adversarial client tests cover fractional and negative inputs.
Proposal updates now enforce the documented `OPEN → ACCEPTED/DECLINED/EXPIRED/CANCELLED` graph, including rejecting higher-revision reopen/accept attempts after terminal decisions while preserving same-state duplicates. Adversarial proposal-transition tests cover accepted and declined terminal paths.
Ticket projections now validate playlist metadata on every update, rejecting unknown values before either phase or playlist state can mutate. An adversarial higher-revision update test covers this boundary.
