  "sourceRowHashesNote": "sourceRowHashes are positional placeholders (sha256:0N00...): the WORLD-aggregate bundle carries one harmonised observation per source, not raw source rows. They enter memberHash (and so the sub-index snapshotHash and the anchored proof blocks) and are therefore preserved verbatim; sourceHash is the real per-source content hash. Member harmonisedValue is the temp-DB Numeric round-trip of the bundle observation and may differ from verify/material/<period>/source-bundle.json harmonised_value beyond 15 significant digits; both sit inside published hashes (memberHash and dataBundleHash respectively) and cannot be aligned without a hash-breaking revision."
