Paul HittandClaude Opus 4.8 6a0f642e0d D4: history the user can carry — encrypted export and import ...

Same design as iOS: the vault's history re-sealed under a passphrase-
derived key (PBKDF2 600k rounds, AES-256-GCM), saved through SAF, merged
back by content identity so the same backup twice adds nothing. Expired
stories stay expired — a backup is not a way back in. The passphrase is
stored nowhere, deliberately.
