Periodic-tier E2E test that catches the original failure mode the
user complained about: 5+ options for ONE decision must split into
N sequential AskUserQuestion calls, not drop one to fit Conductor's
4-option cap.
Fixture: 5 independent chat-platform integration candidates
(Slack/Discord/Teams/Telegram/Mattermost), each carrying its own
include/defer/cut decision. Floor = 4 review-phase AUQs (standard
[N-1] tolerance band). Pre-fix "drop to 4 + 1 dropped" fails this
floor.
Wired into test/helpers/touchfiles.ts: tier periodic, depends on
plan-ceo-review/**, the new preamble subsection, the question-pref
binary (for the carve-out), and the runner helper. touchfiles.test.ts
expected count bumped 21 → 22 to account for the new entry.
Cost: ~$0.30/run when EVALS_TIER=periodic. Skips silently otherwise.
