ADR-0087 exemption (already-registered): this change adds no new transition. It puts the `having` clause of `engine.aggregate` behind refusals the shared comparand-shape face already makes for `where` and `aggregations[i].filter` on the same verb. The arms whose transitions are on the ledger are named: the equality-slot array, the blank `$between` endpoint and the `{ $field }` `$between` endpoint. The first two prescriptions apply to a `having` as written, and so does the third one's literal-bound half; its column-to-column half does not, because `having` resolves no `{ $field }` reference in any slot (a gap this change does not touch, stated in the table below). The null list member, the null `$between` endpoint and the null ordering comparand were ruled at the face with no ledger entry (their changesets declared no-migration-prescription), and the non-list `$in` / `$nin` / `$between` refusal is the face's original rule. `having` is a request-only key: no metadata type stores it, so there is no stored document for `objectstack migrate meta` to rewrite. The table below is the author-facing remedy for each arm, not a mechanical rewrite.
