Struct UpdateSession 

pub struct UpdateSession {
    pub title: Option<String>,
    pub title_pinned: Option<bool>,
    pub cwd: Option<String>,
    pub model: Option<String>,

}

Typed mutable facts for an existing session.

Omitted fields are preserved. Clearing metadata is deliberately not part of this contract; lifecycle operations own destructive state transitions.

Fields

title: Option<String>

title_pinned: Option<bool>

Whether title is a person’s choice, which decides who may overwrite whom. Leaving this None marks the write as derived — a title generated from session content — and derived writes never overwrite a pinned title. That default is what makes an auto-titling caller fail-safe without having to know pinning exists.

title	title_pinned	effect
Some	Some(true)	rename: set the title and pin it
Some	Some(false)	retitle and release the pin
None	Some(_)	change the pin state, keep the title
Some	None	derived: applied only while unpinned
None	None	no title change
