**Administrative Record Integrity** represents the technical "Chain of Custody" for statutory data. It is the cryptographic assurance that tax-relevant data—from invoices to payroll—remains pristine and unadulterated from the moment of ingestion to the eventual FTA inspection.
The Shift to 'Immutability-by-Default'
Under **Federal Decree-Law No. (28) on Tax Procedures**, taxpayers are required to keep records in a manner that enables the FTA to ascertain the tax liability. By 2026, "ascertaining" has evolved into a forensic requirement for **Non-Repudiation**. If an auditor cannot verify *when* and *by whom* a record was created, the integrity is considered "Compromised."
Digital Fingerprinting (SHA-256)
Every document stored in Arakan Vault is fingerprinted when it arrives. If the file is later changed, even by one character, the fingerprint no longer matches, so an altered copy is detected.
The 7-Year Statutory Lock
UAE Law requires records to be kept for **7 years** (15 years for real estate). Record Integrity ensures that the data presented in year 7 is identical to the data recorded in year 1, mitigating "Memory Risk" during long-tail audits.
Mitigating the 'Manual Adjustments' Risk
Traditional accounting software allows for "Journal Adjustments" that frequently leave no forensic trace. Arakan eliminates this audit risk by treating every adjustment as a **New Transaction Node**, linked to the original record, ensuring the auditor sees the *evolution* of the data rather than just the *final state*.
"In a 2026 audit, the question is no longer 'Where is the invoice?', but 'How can you prove this invoice hasn't been re-uploaded with different VAT details?'. Integrity is your only defense against a finding of Administrative Negligence."
