+/**
+ * This library is capable of producing linked summaries from unlinked
+ * ones (or prelinked ones).  It functions by building a miniature
+ * element model to represent the contents of the summaries, and then
+ * scanning the element model to gather linked information and adding
+ * it to the summary data structures.
+ *
+ * The reason we use a miniature element model to do the linking
+ * (rather than resynthesizing the full element model from the
+ * summaries) is that it is expected that we will only need to
+ * traverse a small subset of the element properties in order to link.
+ * Resynthesizing only those properties that we need should save
+ * substantial CPU time.
+ *
+ * The element model implements the same interfaces as the full
+ * element model, so we can re-use code elsewhere in the analysis
+ * engine to do the linking.  However, only a small subset of the
+ * methods and getters defined in the full element model are
+ * implemented here.  To avoid static warnings, each element model
+ * class contains an implementation of `noSuchMethod`.
+ *
+ * The miniature element model follows the following design
+ * principles:
+ *
+ * - With few exceptions, resynthesis is done incrementally on demand,
+ *   so that we don't pay the cost of resynthesizing elements (or
+ *   properties of elements) that aren't referenced from a part of the
+ *   element model that is relevant to linking.
+ *
+ * - Computation of values in the miniature element model is similar
+ *   to the task model, but much lighter weight.  Instead of declaring
+ *   tasks and their relationships using classes, each task is simply
+ *   a method (frequently a getter) that computes a value.  Instead of
+ *   using a general purpose cache, values are cached by the methods
+ *   themselves in private fields (with `null` typically representing
+ *   "not yet cached").
+ *
+ * - No attempt is made to detect cyclic dependencies due to bugs in
+ *   the analyzer.  This saves time because dependency evaluation
+ *   doesn't have to be a separate step from evaluating a value; we
+ *   can simply call the getter.
+ *
+ * - However, for cases where cyclic dependencies may occur in the
+ *   absence of analyzer bugs (e.g. because of errors in the code
+ *   being analyzed, or cycles between top level and static variables
+ *   undergoing type inference), we do precompute dependencies, and we
+ *   use Tarjan's strongly connected components algorithm to detect
+ *   cycles.
+ *
+ * - As much as possible, bookkeeping data is pointed to directly by
+ *   the element objects, rather than being stored in maps.
+ *
+ * - Where possible, we favor method dispatch instead of "is" and "as"
+ *   checks.  E.g. see [ReferenceableElementForLink.asConstructor].
