ADR-0087 exemption (no-migration-prescription): a refusal of filter STRUCTURE at the engine's query door and at its published in-memory aggregation function: a { $field } comparison against a column the spec's crossFieldComparisonVerdict answers no-class for, at having and at a per-aggregation filter, and the reference rules engine.aggregate already applied, now applied by applyInMemoryAggregation when its caller passes a field map. No authorable key, spelling, export or stored shape moves: FieldReferenceSchema, every query shape and every object definition parse as before, the package entries export nothing new and nothing less, applyInMemoryAggregation keeps its signature, and no stored row is read or rewritten. What is refused is a comparison the same query's where already refuses on driver-sql, and which comparable column the caller meant is not something a ledger entry can decide. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers a filter's comparison class (not registered / already-registered); and the change is runtime behaviour, not a declaration (not runtime-interface-only / type-surface-only).
