tmux capture-pane strips the ⬇ (U+2B07) character; grep on it always
returns empty. Switch to case-insensitive text matching on actual
LLM response content (hello, hi, greeting, hey).
Also: reorder tests (cascade-parsing, eval-command, status-bar first
to warm the TUI; agent-responds last), increase handshake timeout
to 60s, increase agent poll timeout to 90s.
TUI integration: 5/5 pass (was 4/5 with false-negative on agent-responds)
- TUI agent-responds: hardened to detect and FAIL on cascade/exhausted
responses (previously a separate WARN-only test that let real
cascade failures slip through)
- New TUI cascade-parsing test: /eval *provider-cascade* on screen,
checks for clean keywords (no cl-dotenv quote artifacts)
- Pre-warm step: sbcl --eval '(ql:quickload :passepartout/tui)'
before launching tmux, cuts TUI startup from ~120s to ~10s
- Removed test_agent_not_cascade_failure (absorbed into agent-responds)
- New integration test: test-provider-cascade-parsing verifies
PROVIDER_CASCADE entries are keywords without quotes, matching
registered backends — catches the exact cl-dotenv quote bug
- Fixed stop-daemon ghost symbol (removed export) and paren bug
- Contract section updated with numbered Phase 2/3 items
