ADR-0087 exemption (no-migration-prescription): The two retired keys were settings values, not metadata: only the platform-shipped brandingSettingsManifest declared them (only platform code declares a settings manifest), SettingsManifestSchema and every other spec declaration are unchanged, and a value stored for one of them lives in sys_setting (runtime state, ADR-0007), not sys_metadata, and is kept as it is. Nothing read either key in objectstack or in objectui at the console pin, so no consumer has anything to rewrite and objectstack migrate meta has nothing to reach. Withholding the branding namespace under a walled posture moves no stored row either. The one operator-facing consequence there, that OS_BRANDING_WORKSPACE_NAME stops naming sign-in mail and the OS_APP_NAME variable takes its place, is a deployment environment setting: no consumer code and no metadata is rewritten, so the ledger has nothing to carry and objectstack migrate meta nothing to reach. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers a settings key (not already-registered); and the change is the value of an exported manifest constant and the plugin's registration behaviour, not an interface or a type alone (not runtime-interface-only or type-surface-only).
