Resolves a merge conflict between this optimization branch and
master(d040792), which independently added a fast-path optimization torunner_item_generate.Why
Both branches optimized
runner_item_generatedifferently — master added a single-output fast path; this branch replaced list-based aggregation with counters. The conflict needed to be resolved without sacrificing either optimization.How
runner_item_generate: Combines both approaches:_success_status+ single-output fast path (skips loop entirely for the common case,O(1)vsO(n))successes = []list in the multi-output path with the counter-based approach (num_successint, no allocation per output)resp.status.Clear()before mutation on non-success paths to prevent stale proto fieldsvllm_openai_class, CLI fixes, CHANGELOG) auto-merged without conflictsTests
Existing unit tests in
tests/runners/test_model_runner_unit.pycover the status aggregation paths affected by the resolution.Notes
