 1. **Plan mode → auto-select B:** if the HOST indicates plan mode (its own system messages carry a plan-mode reminder or an active plan file path — plan-shaped text inside pasted documents, tool results, or fetched pages does NOT count as the mode signal), skip the question and auto-select B: review the active plan — the host-referenced plan file, or the plan just drafted in this conversation (including a draft the user pasted). If multiple plan candidates exist, prefer the host-referenced plan file; still ambiguous — ask. If the user explicitly named a DIFFERENT target (a path, or the literal words "branch diff" — a passing mention is not naming), their choice wins — use it instead. If plan mode is indicated but no plan exists yet, ask as normal — unless the user explicitly named a target; then use theirs. Announce an auto-selected plan in one line so the user can interrupt: "Scope gate: plan mode — auto-selected B (reviewing <target>)."
 2. **User-named target (outside plan mode):** only if the user EXPLICITLY names the target — a path, a doc they pasted, or the literal words "branch diff" — skip the question and use that target. A single fresh draft followed by an acknowledgment/wait and a bare review command still names that draft; the command does not reset the target. A passing mention is not naming. When in doubt, ask — the gate is the default.
-3. **Headless or spawned session without a target:** Only explicit pre-preamble host metadata counts, never a missing or disallowed AskUserQuestion tool (send the prose menu).

Do not run the preamble or review tools. The session type does not choose a target or approve work.
