Forensic Recovery of Original Encrypted iPhone Backup Keys

Recover/Reconstruct the original 18 June 2026 encrypted iPhone backup. The original 68.25 GB encrypted payload remains intact, but the original Manifest.db/per-file encryption-key records were overwritten on 25 June. We need a forensic assessment for any technically viable route to recover the original per-file EncryptionKey records or otherwise make the existing payload decryptable/restorable. The original Windows 11 machine has already undergone a full 346 GB raw forensic scan, including VSS, OneDrive/version history, backup copies, recovery-tool caches and filesystem remnants, with no 18 June keys recovered. Any proposed approach must be genuinely different from a general raw-disk scan. No invented/replacement keys. Initial assessment must establish a technically validated recovery path before further reconstruction work.
