Class ModelReducer

java.lang.Object
io.fluxzero.sdk.modeling.ModelReducer

public final class ModelReducer extends Object
Sole executor for the immutable handler and target knowledge in MutationPlan.

Interceptor outputs form ordered substeps under one pinned read boundary. Within a substep, payload handlers first produce one immutable intermediate state and model handlers then consume that complete state. Handlers within either phase never observe partial sibling results; only the composed final state becomes visible to later substeps. This class owns handler invocation, result validation, ordering and staged Graph changes for live handling, retry, rebase and reconstruction.
