transcript.rs

//! Transcript data shared by the worker, controller state, and the chat UI.
//!
//! [`ChatEntry`] is what a worker snapshot carries in its transcript tail and
//! what the chat view renders, and [`TranscriptItem`] is the materialized
//! form controller state persists, so both live below the modules that use
//! them rather than inside any one of them.
//!
//! The text helpers that read one of those shapes live here for the same
//! reason: the database, the projection, controller state, the compactor and
//! the review host all need the plain text of a stored message, and none of
//! them should have to reach up into the chat view to get it.
