/**
 * @module @nhtio/adk/batteries/orchestration/cells/structured
 *
 * The `structured` predicate cell.
 *
 * This cell evaluates a declarative, JSON-shaped predicate tree against a
 * bounded, already-materialised plain-data snapshot of a run's outputs. It is
 * the default predicate evaluator for most plans because it has no external
 * dependencies: there is no parser to load and no runtime to initialise, so it
 * can never fail for a missing peer.
 *
 * Two properties hold by construction and are worth keeping in mind when
 * reading this cell:
 *
 * 1. It reads a plain-data snapshot rather than live objects. The predicate
 *    only ever touches values reached through `readPath` on the marshalled
 *    outputs, so it never invokes reachable methods or getters and cannot be
 *    surprised by object identity or prototype chains.
 * 2. It uses no clock and no randomness. A branch or select node is therefore
 *    safe to re-enter unconditionally when a run resumes: re-evaluating the
 *    same predicate against the same snapshot always yields the same verdict.
