Layer 1: Unfixing. During the initial constraint propagation, if a neighbor cell creates a contradiction, the solver converts it from a fixed constraint back into a solvable cell. Its own neighbors (two cells out — "anchors") become the new constraints. This is cheap and handles easy cases.
The second benefit is that we get dynamic dependencies for free. If pull-based reactivity is just a call stack, then it’s very easy to conditionally call (i.e. conditionally depend on) some input. We don’t need to maintain an internal list of which dependencies a node is subscribed to or vice versa, we just fetch values as needed.
