Cross-Check Session
For holders who recently updated a backup and want confirmation before archiving the old version.
Scope
This shorter session covers the comparison phase of our full audit. It suits holders who are confident in their storage setup but need verification after re-writing, engraving, or relocating a backup.
Process
You arrive with at least two copies. We walk through word-by-word comparison, checksum validation, and a single derivation test on an air-gapped device we provide. No written report is included; you receive annotated worksheets to keep.
Preparation
Do not photograph or digitise your phrase before arriving. Bring only physical copies.
