/**
 * autoplan AskUserQuestion-blocked regression (gate, paid, real-PTY).
 *
 * v1.21+ regression: Conductor launches Claude Code with
 * `--disallowedTools AskUserQuestion --permission-mode default` (verified
 * by inspecting the parent claude process via `ps`). The native
 * AskUserQuestion tool is removed from the model's tool registry; without
 * fallback guidance the model can't ask the user and silently proceeds.
 *
 * Autoplan auto-decides INTERMEDIATE questions BY DESIGN
 * (autoplan/SKILL.md.tmpl:45), but Phase 1's premise confirmation gate is
 * one of the few non-auto-decided AskUserQuestions and MUST surface to the
 * user. This test asserts that gate still surfaces when AskUserQuestion is
 * disallowed at the tool-registry level — the fix must route the question
 * through a Conductor-side variant (mcp__conductor__AskUserQuestion) or
 * through the plan-file + ExitPlanMode flow.
 *
 * Filename keeps `auto-mode` for branch-history continuity. Auto-mode (the
 * AUTO_DECIDE preamble path when QUESTION_TUNING=true) is a related but
 * distinct silencing mechanism; both share the same fix surface.
