- Added -ixon to stty so Ctrl+Q (XON byte) isn't swallowed by the terminal driver and reaches the TUI as :CTRL-Q - view-input now truncates the prompt (> prefix + visible text) to chat-w - 2 characters, and the hint to chat-w characters, so neither extends into the sidebar area

Passepartout TUI — View
View
| Pure render functions. Each takes the cl-tty backend and current state. |
State is read via (st :key) — no mutation here. |
Contract
- (view-status win): renders the status bar with connection info, msg count, scroll offset, rule counter, focus map (v0.4.0), and timestamp. Two lines: line 1 (status + rules), line 2 (focus + time).
- (view-chat win h): renders the scrolled chat message list. Takes window and available height. Messages are color-coded: green (user), white (agent), yellow (system).
- (view-input win): renders the input line with cursor and typing indicator.
- (redraw sw cw ch iw): dispatches redraws based on
(st :dirty)flags (status, chat, input). Minimizes terminal writes. - (char-width ch): returns the terminal column width of character CH. ASCII < 128 = 1. CJK, fullwidth, emoji = 2. Combining marks = 0. Tab = 8. Used by word-wrap for accurate line counting (v0.7.0).
- (view-status win): v0.7.0 — timestamp right-aligned at (- chat-w 12) on line 2, focus info at :x 1. No overlap.
Status Bar
The status bar, as of v0.4.0, renders Passepartout's three differentiator visualizations — data only available because of the deterministic gate architecture:
- Rule counter (
Rules:N): the number of pending HITL actions from the Dispatcher's*hitl-pending*hash table. The user watches this tick up as they teach the agent their preferences through approve/deny decisions. - Focus map (
[Focus: <id>]): the foveal focus from the daemon's signal context. Shows the user what the agent is currently looking at. - Gate trace (not rendered in status bar — attached to individual
messages via
:gate-tracefield for future collapsible rendering per message).
All three enrichments cost 0 LLM tokens — they are daemon-state queries that the TUI actuator attaches to the response plist before transmission.
