Struct ThreadLeafState 

pub struct ThreadLeafState {
    pub thread_id: String,
    pub leaf_id: Option<String>,
}

Persisted thread metadata extension for the tree. This is the current_leaf_id column added to state.threads; None before the first turn, Some(id) after. The existing threads JSON shape is otherwise unchanged (back-compat: old rows read as None and the next append mints the header leaf).

Fields

thread_id: String

leaf_id: Option<String>
