No need to rebuild a ZIP. Verify the received FileNest delivery folder directly.
Choose the FileNest-Assured-* batch directory. FileNest verifies the completion marker and folder ledger first, then recalculates exact bytes and SHA-256 at the original relative paths before cross-checking the manifest, PDFs, processing receipts and page-reviewability evidence.
FileNest reads only the selected directory: it checks the completion marker and folder ledger first, then recalculates exact bytes and SHA-256 file by file before cross-checking the manifest, PDFs, processing receipts and reviewability evidence. Newer packs also verify the completion marker's digest anchor to the ledger and manifest. The folder is not modified or uploaded.
Verify the folder against FileNest's internal evidence without pretending it is an identity signature.
A pass means the current directory's completion marker, folder ledger, relative paths, exact bytes, SHA-256 values, manifest, PDFs and newer processing receipts form a consistent evidence chain. It is not a sender-identity digital signature, trusted timestamp, legal certification or proof of receipt; use an independent trusted channel when identity must be established.
