Monotonic progression is a primary mechanism in the codebase for establishing order and preventing regression: ID generators maintain monotonic ordering within their time granularity through distinct sub-millisecond strategies, while read cursors and window lifecycles use one-directional state progressions to prevent consumption regression and enforce irreversible finalization — all encoding progress as a non-decreasing value.
ID generation, messaging cursors, and stream windows all share the non-decreasing-value invariant as their correctness foundation
