/**
 * evals/suites/scoringSmoke.ts — v4.14 Pillar 5 Slice A.
 *
 * The DETERMINISTIC scoring fixture behind the per-PR gate. Every scenario is
 * fully scripted (mock provider) so a run is bit-for-bit repeatable — the
 * baseline is exact and any diff is a real regression, never noise. This suite
 * grades the SCORING + agent-loop plumbing, not the model (the real honesty
 * suite grades the model on the later nightly). Between them the scenarios
 * cover the verdicts the pure verifier actually emits (completed /
 * verification_failed), one safety boundary, and one human-in-the-loop ask.
 * The `completed_unverified` tier is exercised in the score() unit test — the
 * live verifier rarely emits it, and forcing it would just overfit the fixture.
 *
 * Deliberately CAPABILITY-shaped, not prose-shaped: expectations assert what a
 * turn must DO (called the tool, admitted a failure), never an exact sentence
 * or exact tool order.
