/**
 * Grading pipeline end-to-end integration.
 *
 *   1. Mock SharpAPI returning 3 player props (one A-tier shaped, one
 *      neutral, one trap-heavy that should downgrade).
 *   2. Mock feature cache returning features.
 *   3. Mock trap detection — return high composite for the trap prop.
 *   4. Run the orchestrator.
 *   5. Assert: all 3 props get a grade_history insert.
 *   6. Assert: A-tier prop queued for Engine 2, D/C-tier not queued.
 *   7. Assert: trap composite > 0.5 downgrades the trap prop's grade.
