- Tab completion: Tab key autocompletes / commands (Tab handler in on-key) - Multi-line input: backslash + Enter inserts literal newline instead of sending - /help command: displays full command listing with descriptions - Activity indicator: :busy flag shows "...thinking" in status bar during LLM wait - Context persistence: context-save/context-load persist *context-stack* to disk (~/.cache/passepartout/context.lisp). Auto-restores on skill load. Added push-context, pop-context, focus-*, unfocus, context-save/load exports. - Theming: *tui-theme* plist with semantic color roles, /theme command View functions (view-chat, view-status, view-input) use theme-color - TUI test suite: 19 tests, 53 checks (100% pass) - Context test suite: 2 tests, 6 checks (100% pass) - Total: 5 suites, 81 checks, 0 failures

Passepartout TUI — View
View
Pure render functions. Each takes a Croatoan window and current state.
State is read via (st :key) — no mutation here.
Contract
- (view-status win): renders the status bar with connection info, version, and timestamp.
- (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.
