Select the canonical MailVault root, run preflight and create or open a profiler workspace. The source is always read-only.
Choose a completed physical-profile run. Alpha 4 attaches exact format assertions to this baseline; it does not create a new archive.
Search content objects and inspect filename/message occurrence history. SHA-256 is identity; filename is evidence.
Review physical findings using append-only statuses. Review state never modifies MailVault.
The Exact formats view:
- resolves the bundled or configured Siegfried sidecar;
- displays observed tool/signature identity;
- shows eligible object and byte totals;
- starts or resumes the versioned format run;
- streams exact object progress;
- exposes state, PUID, search and mismatch filters.
Extension status meanings:
- Mismatch — a safe extension alias was checked and the tool reported mismatch evidence;
- No mismatch — an alias was checked and no mismatch warning was reported;
- Not checked — no reliable extension alias was evaluated.
Unknown and ambiguous are evidence queues, not application failures. Tool errors require technical review.
