 | an unknown or retired operator (`$median`, `$regex`), or an empty or non-string `$icontains` | refused only when a grouped row reached it: an empty grouped set, a condition on a column the row does not carry, or a `$or` whose earlier branch held all answered without an error | the operator the refusal names |
 | `{ total: { $field: 'max_cap' } }` (a reference with no operator) | refused as an unsupported operator, again only when a grouped row carried `total` | `{ total: { $eq: { $field: 'max_cap' } } }`, or `$ne` / `$gt` / `$gte` / `$lt` / `$lte` |

-| a `{ $field }` reference naming a column the aggregated row does not have, or carrying an `addDays` that is not an integer or a `{ $field }` | compared the reference object itself, so the answer depended on the operator: no group under `$eq`, `$gt` and `$gte`; every group under `$ne`; under `$lt` / `$lte`, every group against a text or date column (the object compares as the text `[object Object]`) and no group against a number column | a groupBy projection or an aggregation alias of the same query (the refusal lists them); a whole-day `addDays` |

 Not refused, but answering differently:
