ADR-0087 exemption (no-migration-prescription): a refusal at the analytics door of a caller-named measure spelling whose inferred source names no field. No authorable key, spelling, export type or stored shape moves: AnalyticsQuerySchema still parses every measures list it parsed (the refusal is a runtime rule on the request, not a schema change), CubeSchema and DatasetSchema are untouched, a member a cube declares is never minted and is served as before, the package index exports the same names with the same types, and no stored row is read or rewritten. A refused spelling had no answer to preserve: both strategies answered 500 for it, and which column a caller meant by an empty prefix is not something a ledger entry can rewrite. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers a caller-named measure spelling, and this diff adds none (not registered / already-registered); and the change is runtime behaviour, not a declaration (not runtime-interface-only / type-surface-only).
