As a user I want to sign out of my account so that my identity is no longer active on this device.

This is simply a change of copy. Remember Vault → Identity:

Acceptance Criteria

Sign out is accessible from the avatar dropdown menu

Tapping sign out shows a confirmation modal before any action is taken

Modal title: "Sign out?"

Modal text: "Your identity will no longer be active on this device. You can sign back in at any time."

Buttons: Cancel and Sign out

Confirming sign out removes the identity from the device and returns the user to the signed-out state

The avatar icon reverts to the outlined/dashed state

If the user has multiple accounts, signing out of one account switches to the next available account instead of returning to a fully signed-out state

Basic Flow

User clicks avatar → Sign out

Confirmation modal appears

User clicks Sign out

Identity removed from device

User returned to signed-out state — avatar reverts to outlined icon

Edge Cases

User taps Cancel → modal closes, nothing changes

User has multiple accounts → signs out of active account, app switches to next account automatically

User signs out and immediately tries to sign back in → standard sign-in flow, i

⚠️ User has a local-only identity and signs out → identity is no longer accessible on this device and cannot be recovered without a backup. Worth adding an extra warning in this case
