//! Telling a chat how a task it filed ended.
//!
//! A chat is single-turn: it speaks only when the operator writes, so "I will
//! tell you when it finishes" cannot be kept by the agent. This module keeps
//! it for the agent. When a task filed by a chat ([`Task::filed_by_chat`])
//! reaches a final state, a fixed English notice is queued as a draft of the
//! originating talk, and the talk's own turn machinery (its session, its
//! lease) runs it. No new seat and no new waiter: the same shape as
//! [`crate::consult`].
//!
//! - **A reconciler, not a hook.** [`sweep`] looks at the queue on every
//! daemon tick, so whoever put the task in its final state (the loop, `magi
//! task done`, the web UI, a restart) is covered the same way.
//! - **Once.** The task records what was reported ([`Task::chat_notice`]); the
//! talk records the accepted key in the same write as the draft
//! ([`talk::queue_once_matching`]). A crash between the two writes is repaired by the
//! next sweep, which finds the key in the talk and only fixes the task.
//! Lock order is task, then talk.
//! - **Closed or gone is skipped,** never reopened (unlike a consult).
//! - **A parking upgrade starts nothing.** The draft stays durable.
