# Event Sourcing Event sourcing reconstructs state from an append-only sequence of recorded events rather than only preserving a final snapshot. [[Scanned_20260803-1201]] independently approximates this method through numbered envelopes, dated receipts, signatures, device labels, custody tokens, and later provenance statements. ## Archive significance The packet is a personal event ledger, but many entries still lack a master manifest, precise acquisition time, or external corroboration. See [[Personal Digital Continuity]] and [[Chain of Custody]].
