nanalLabs BlogSeals stack as versions. That is why you can open a past state of any note, roll back to it, and even recover notes you deleted.
Opening a past version
In a note's proof & timeline, click "Local" on any history row. That version's text opens read-only — you look into the past without touching the current note.
Rolling back to a version
"Restore this version" offers two choices — restore as a copy (current note untouched, a copy is created) or restore in place. When in doubt, choose the copy.
Recovering deleted notes — Rewind
Ribbon → "Rewind — find deleted notes" lists only the notes deleted from this vault. Pick a note and a version, and the restored text comes back byte-identical to the original — and is resealed immediately, so the fact that a restore happened is itself on record. Even recovery cannot be done quietly; that is a property of the seal chain.
Rebuilding everything — bulk restore
Changed machines, or lost the vault entirely? Ribbon → "Bulk restore (from nanalStorage)" reconstructs your notes in their original folder structure, attachments included (free twice a year). Afterwards, a reconstruction report records what was restored and what wasn't — notes from your free-tier days whose originals haven't been uploaded yet are listed as "no stored copy." That is honest reporting, not failure.
To browse everything stored in the cloud, use ribbon → "Browse stored notes" — a note browser with vault filters and per-note version history.
