/** Lazy view of `sf.substreams.sink.database.v1.DatabaseChanges`: nested and repeated message fields are

 [`::buffa::LazyMessageView`] for the deferred-validation contract;
 the eager, whole-tree-validated counterpart is named `DatabaseChangesView`.

/** Lazy view of `sf.substreams.sink.database.v1.CompositePrimaryKey`: nested and repeated message fields are
 recorded as undecoded byte ranges and decoded on access. See
 [`::buffa::LazyMessageView`] for the deferred-validation contract;
 the eager, whole-tree-validated counterpart is named `CompositePrimaryKeyView`.

 Oneof variants, map values, groups, and extern-typed fields (e.g.
 well-known types) hold eagerly-decoded `CompositePrimaryKeyView`-family
 types; only singular/repeated message fields defer.
