c45a07e5 swapped the opencode harness default to moonshotai/kimi-k2, which broke push-enabled (Kimi reported delete_branch as "auth failed" where sonnet handles it). The agnostic test matrix expects Sonnet-grade tool-calling; switching to Kimi was scope creep on top of the original "don't default to opus" ask — opencode's default was already sonnet, not opus, so nothing needed to change there.
