New information enters a frame through composition with adjacent frames. When two frames interact, they refine their shared relations and this update is local, meaning it doesn't require a global time variable. Instead, each composition increases the frame’s informational content, enriching its internal structure and making more distinctions possible.
Because composition is monotonic, you can’t lose information by resolving more, this creates a natural arrow of time: the frame's informational structure becomes strictly more refined (or at least never less refined), which gives rise to a directional, causal ordering of updates.
