Voltius v0.27.0

Added

• Voltius now answers voltius:// links. A session invite, a team invite or an
  email verification opens the app straight on the thing it points at, on
  desktop and on mobile. Links are routed through a table that classifies each
  one by how much it is trusted, and a link that arrives before you are signed
  in is queued and replayed once you are. Verifying your email no longer needs
  the manual "I've verified" click.
• Live session invites can be read out loud: alongside the link, a share now
  offers a short spoken code that a teammate can type into the join field.
• Vault backups are visible. When a save is quarantined because it could not be
  opened, the vault panel lists the kept backups with their real sizes and
  offers to restore one, instead of leaving them as files on disk you were never
  told about.
• The People section in the share menu reads as clickable, and Recent entries
  can be pruned.

Fixed

• A cloud vault is unlocked with the key that actually encrypted it, and that
  key survives re-authenticating with the cloud. Signing back in no longer
  leaves the vault unopenable on the device that created it.
• The vault never deletes secrets.enc when no key opens it, writes it
  atomically so an interrupted save cannot truncate it, and stops retention from
  deleting backups a recovery run never attempted.
• Vault failures are told apart from missing data: "vault unavailable" is no
  longer read as "no credentials saved", the locked-store error from the Rust
  side carries the vault-locked code, and that code survives the reconnect loop.
  A form now says outright when a secret could not be read instead of showing a
  blank field.
• Sync now carries the vault list — which vaults exist and what they are
  called — in the encrypted blob, so a second device stops showing objects whose
  vault it cannot name.
• A new vault key is uploaded before the vault is re-encrypted to it, so a
  failure mid-rotation cannot strand the vault.
• An account with no password whose vault cannot be read is sent to recovery,
  and the vault is unlocked before the legacy migration runs.
• Connecting from the SFTP side pane while the vault is locked now shows the
  vault panel rather than failing silently.
• The account quick switcher no longer carries one account's state into
  another's, signing out drops the saved credentials, and the rest of an
  account's local state moves with the account. Reaching a second account from
  the switcher works again.
• Auto-lock is reachable from the account menu.
• An invite link stays reachable after the share menu closes, presence is shown
  on Recent rows with a dot that actually paints, the members popover floats
  above the header, and your own presence is trusted.
• The invite search says it accepts handles, not just email; the members popover
  title is translated in Russian and Chinese.
• A button's ripple releases its listeners and timers when the button unmounts.
