#+TITLE: Passepartout TUI — Model
#+PROPERTY: header-args:lisp :tangle /home/user/.local/share/passepartout/lisp/channel-tui-state.lisp

* Model

The TUI state is a single plist accessed via ~st~ / ~(setf st)~.
All state mutation flows through event handlers in the controller.

** Contract

1. (init-state): returns a fresh state plist with ~:msgs~ list,
   ~:input~ buffer, ~:dirty~ flag, ~:busy~ flag, and ~:connection~ status.
2. (add-msg role content &key gate-trace): appends a message object
   to the ~:messages~ vector (v0.3.3), tagged with timestamp, role,
   and optional gate-trace from the daemon (v0.4.0).
3. (queue-event ev): thread-safely enqueues an event for the
   reader loop. (drain-queue) returns and clears the queue.
