The disaster-recovery backup selected every Measurement scalar except the aggregation fields, so a restore brought every `stats:` aggregate back with no provenance and the Apple Health authority ladder came back flat: an export.xml source-day estimate could then overwrite a native HealthKit statistic. `aggregationProvenance` now rides the select, the disaster-recovery serialization, the payload schema and the restore mapping, following `externalSourceVersion` exactly — including staying out of the reduced portable shape, which carries the human-readable subset only. The schema field is optional, so every backup written before this parses unchanged. Restoring one of those older backups no longer recreates the ambiguity migration 0263 repaired: an Apple Health row under a `stats:` identity with no provenance comes back as LEGACY_UNKNOWN, the sentinel the cumulative drain already writes in that situation, so a native sync or archive reprocess can repair it. The gate is scoped as 0263 scoped its backfill — other providers mint `stats:` identities for their cumulative dailies and have never carried provenance, and ordinary point rows keep NULL.
