ADR-0087 exemption (no-migration-prescription): a change of which rows the analytics read scope and the draft preview select for a value comparison on a declared datetime, date or time column, not of anything an author writes: no spec key, spelling or stored shape moves. AnalyticsQuerySchema, CubeSchema, DatasetSchema and every RLS policy parse and save as before, the package index exports the same names, and no stored row is read or rewritten. The two new options members are optional and identity when absent, so every existing caller of compileScopedFilterToSql compiles as before. What moves is the row set such a comparison selects, which now equals the engine's own answer for the same filter, so there is nothing for objectstack migrate meta to rewrite. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers a filter comparand's storage form and this diff adds none (not registered / already-registered); and the change is runtime behaviour, not a declaration alone (not runtime-interface-only / type-surface-only).
