 - blank optional `title`, question `label`, option `description`, and option `preview` fields are treated as omitted
 - question `label` falls back to `Q1`, `Q2`, ...
 - option `label` is required in the public schema; before schema validation, a missing or blank string label is derived from a non-empty `value` by replacing hyphens and underscores with spaces and capitalizing the first character
+- `recommended` is optional presentation metadata; zero, one, or multiple options may set it to `true`
+- recommended options render warning-colored `(recommended)` followed by muted ` | <description>`, or only `(recommended)` when no description exists, but are not preselected
 - `type` defaults to `single`
 - `required` defaults to `false`
 - `required` is metadata only; it never blocks submission

 - `continuation.affectedQuestionIds` lists the only questions that should be revisited

 - single-select answers still use arrays
+- recommendation markers never change canonical submitted labels or values
 - when `behaviour.presentSingleAsMulti` is enabled, requested single-select questions are presented and handled as multi-select in future/replayed ask flows; result question metadata keeps the requested `type`, adds `presentedType` when final presentation differs, and result text uses one compact note when any answered questions were presented differently
 - `indices` are 1-based rendered option positions
