Subject: [PATCH] remove: delete journey-think-bigger routing test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Never passed reliably. Tests ambiguous routing ("think bigger" →
plan-ceo-review) but Claude legitimately answers directly instead
of invoking a skill. The other 10 journey tests cover routing
with clear, actionable signals.
