- 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
