Subject: [PATCH] test: fast-lane suite asserts Ollama's native thinking-off
 shape
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Routing a task-level ``reasoning_effort: none`` through the provider profile
means the certified Ollama fast lane now sends the profile's own disable
shape — top-level ``reasoning_effort="none"`` plus ``think=False`` — instead
of forwarding a pass-through ``extra_body.reasoning`` that Ollama's /v1 does
not read. The two fast-lane tests encoded the old pass-through; they keep
their intent (thinking is off, and only on the certified route) against the
native wire.
