Enum LifecycleState 

pub enum LifecycleState {
    Active,
    Archived,
    SoftDeleted,
    HardDeleted,
}

Lifecycle state of a session.

Allowed transitions:

• Active ↔ Archived, Active → SoftDeleted, Active → HardDeleted
• Archived → SoftDeleted, Archived → HardDeleted
• SoftDeleted → Active, SoftDeleted → HardDeleted
• HardDeleted is terminal

Variants

Active

Session is live and accepts reads/writes.

Archived

Session is hidden from default listings but remains readable; can be restored to Active.

SoftDeleted

Session marked for deletion; hidden from listings, reversible via restore.

HardDeleted

Session physically deleted (terminal state); messages and subtree gone.

Parse from lowercase string (returns None for unknown values).

pub fn can_transition_to(&self, target: &LifecycleState) -> bool
