Struct TaskEnding 

pub struct TaskEnding {
    pub call: String,
    pub status: Option<ToolCallStatus>,
    pub summary: String,
    pub text: String,
    pub at: usize,
}

What a persisted task ending says, which is what the live wire’s task_notification frame says: the CLI writes the frame’s fields as XML into the transcript instead.

Public because Rendered carries them: a caller building turns needs the endings the fold already read, rather than a second walk to find them.

Fields

call: String

The call it ends, from the notice’s <tool-use-id>.

status: Option<ToolCallStatus>

How the task ended. None for a word this does not know.

summary: String

The harness’s own sentence about the outcome.

text: String

The notice as the CLI wrote it, which a carried copy repeats verbatim.

at: usize

Where the notice sits in the conversation it was read from, which is what says whether a turn already holds it.
