/**
 * The lifecycle of a snippet in the SQL editor, modelled as a single set of
 * mutually-exclusive states.
 *
 * The status is attached to a snippet as it enters the app: 'saved' when
 * fetched from the database (see the snippet queries in this directory) and
 * 'new' when created locally (see createSqlSnippetSkeletonV2). The transition
 * and predicate helpers live in state/sql-editor/sql-editor-lifecycle.
