ADR-0087 exemption (already-registered): this narrows the engine's own in-process evaluator to the rule that registered entry already records: its reason states that every query face refuses a non-boolean $null / $exists flag, its surface names a query having, the data-engine aggregate call's having and an aggregation filter among the carriers, and its replacement is this change's whole migration (a flag is the boolean itself; $null true is "has no value", $exists true is "has a value"). This change makes that statement true on the per-aggregation filter and having positions, which the engine evaluates itself after the driver. No authorable key, spelling, export or published type moves, and no stored row is read or rewritten; a stored filter carrying such a flag is already refused when it is saved, by that entry.
