Replaced software cursor (draw-text █ every frame) with native terminal cursor (position-cursor using cursor-move + cursor-style). Terminal handles blinking natively at 500ms — no redraw needed for cursor updates. - position-cursor: computed input insertion point from state, calls cursor-move + cursor-style (:block :blink t) + cursor-show. - Called from main loop every frame after (sleep 0.1), outside redraw's begin-sync/end-sync. No flicker.

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 fb w h): no-op. Status bar is a clean black line.
- (view-chat fb w h): renders scrolled chat messages. User messages get amber left border (│), agent messages no border, streaming agent gets grey left border. Gate traces/tool calls use ╎ prefix.
- (view-input fb w h): renders expanding light grey input box, multi-line word-wrapped prompt, software blinking cursor (█), right-aligned lowercase hint at h-2.
- (redraw fb w h): wraps view-status/chat/input in begin-sync/end-sync, dispatches per dirty flags, fills global :bg first.
- (char-width ch): returns 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).
- (sidebar-visible-p w): returns T if sidebar should show given width W and current :sidebar-mode (:auto >120, :visible always, :hidden never).
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.

v0.7.1 — Markdown Rendering
render-styled accepts a (text . plist) segment list from the span
parser and emits draw-text calls. The w parameter is ignored (layout
is line-at-a-time, not fixed-width); theme-color is fully qualified
as passepartout.channel-tui:theme-color since this function lives in
the passepartout package but the theme API is in passepartout.channel-tui.
The inline span parser (parse-markdown-spans) delegates punctuation
delimiters (bold, `code`, italic) to a local pick helper.
URLs are handled directly via url-end rather than through pick,
so the :url clause was removed from pick's case form to avoid
dead code.
