Telecom domain had 20 simulations terminated due to too_many_errors (all scored as 0). Banking domain had 52 simulations terminated due to max_steps (all scored as 0). Banking domain evaluated with terminal-based agentic search retrieval (terminal_use). banking_knowledge re-graded under tau2-bench v1.0.1 grading fixes on 2026-07-15 (extra-read logging #329, numeric-argument normalization #397, T077-T086 gold trajectories #402); scores prior to v1.0.1 are not comparable.",
