此前测试都直打 runGraph/evaluate，绕过真正的任务入口 Handle()——熔断、输入护栏门控、 状态机流转、token 预算、异步评测/用量这些治理逻辑的协同从未在入口级被覆盖。 新增 handle_test.go 6 例（全 fake 依赖，可断言各出口）： - HappyPath：running→done + token 流出/收尾 + 异步评测落库(ok) - ToolFeedsAgent：图执行→工具→agent 全程经 Handle，工具被调、产出注入 - CircuitBreakerOpen：熔断开 → 快速 failed、不执行图 - BudgetExceeded：meta token_budget=3 → failed + 用量回写带 Exceeded - GuardrailBlocks：灰区 + LLM 分类器命中 → rejected、不进 running - EmptyTaskDropped：空 id 直接丢弃、无状态回写 配套 fakeStatus/fakeUsageSink；fakeEvalSink 加锁（Handle 异步评测在 goroutine 写）。 go test -race ./internal/eino 干净，四模块全绿。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
