Things are taken one at a time and set in place within an order that holds steady from one occasion to the next. What's noticed in a thing is how it fits. What's placed stays placed, so understanding thickens along a single continuous line, and the order itself isn't up for revision.
A situation lands whole, in one pass, against an inner measure that doesn't move with it. Whatever falls short shows immediately, and the verdict arrives with the perception, not after it. Once delivered it's spent: the next encounter starts clean, and the measure is unchanged by it.
Many signals settle at once into a read of what's happening, taken from the surroundings and weighted toward what in them is sound. The read re-forms as circumstances turn, and so does what it's measured against. Earlier reads don't linger to contradict it, so what's held is only ever the live situation.
How a thing reads depends on when and where it's caught, and on how it lands. What's wrong in it surfaces first and gets traced back, step by step, to what went wrong before it. Attention stays on the fault after the moment has passed, and each one found is kept, so the record only grows.
