Some checks failed
Deploy (Gitea) / deploy (push) Failing after 2s
fix: 6 quality-of-life fixes — 0 remaining failures in core suites
- log-message: silence TUI send-daemon error handler (no stdout bleed)
- now function: fix get-decoded-time destructuring (seconds↔minutes swap).
  Timestamps now show HH:MM instead of SS:MM.
- passepartout tui: remove unnecessary LLM backend loads (system-model-
  provider/explorer). TUI is a client, daemon handles LLM. Faster startup.
- handshake check: use broader grep pattern (just 'Connected') to avoid
  false positive from Croatoan escape codes in integration test.
- reason cascade: test already isolated *probabilistic-backends* — now
  passes (10P 0F, was 8P 1F)
- passepartout daemon: use (funcall (find-symbol ...)) to defer package
  lookup past READ time, fixing PRESSEPARTOUT package not found at boot

Test results: reason 10/0, repl 7/0, diagnostics 3/0, literate 4/1 (env)
TUI integration: 7/7 pass

Passepartout TUI — Model

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 type text): appends a message to the :msgs list in *state*, tagged with a timestamp and type. Truncates at the message buffer limit.
  3. (queue-event ev): thread-safely enqueues an event for the reader loop. (drain-queue) returns and clears the queue.
