The Gemini effort fix (ee9e9c1f) adds a flat reasoning_effort to every
Google chat-completions request at the session default knob — the
golden fixtures now carry it. Only the eight google__* goldens change
(one added key each); other providers' goldens are untouched — the
UPDATE_WIRE_GOLDENS pass also wanted to rewrite twelve passing goldens
with escape-format-only churn (raw em-dash vs \u2014), reverted to
keep the diff semantic.
Captures the exact request kwargs each provider hands to its SDK seam (Anthropic
messages.stream, OpenAI chat/responses create, Google OpenAI-compat) for a
representative set of trajectories, asserted against committed goldens. This is the
behavior-equivalence net the canonical-trajectory wire-shape refactor is proven
against. Regenerate the baseline with UPDATE_WIRE_GOLDENS=1.
