… heartbeats The out-of-process watchdog treated a missing heartbeat file as healthy (!mtime → return forever), so a CI runner reclaiming the tmpdir file left the guard silently disarmed — the 2026-08-17 teardown hang burned the full 15m step timeout with no kill despite --progress arming the watchdog. Track missing-since and kill after the timeout instead. Also heartbeat the teardown phases (disposeApps per-app, cleanup, complete): the 2026-08-17 hang sat after 'summary pass=229' with zero attribution; the next hang names the teardown stage it froze in.
…tract The Router's judgment charter lacked the positive obligation behind every disposal: implementation is not the finish line. Encode it as the contract's leading principle (bilingual key prompt): after implementation, keep iterating verification until the delivery bar the user demanded is genuinely met, and the Router owns every judgment on that loop — replan when evidence is insufficient, flow reorganization (extend/replan) when the outcome deviates, a new DAG when the graph is exhausted. Neither a completed node nor a green build closes the loop; only the user's delivery standard does.
fix(test): watchdog silent stand-down on missing heartbeat + teardown heartbeats
feat(policy): verify-to-delivery doctrine in the Verdict Disposal Contract

本批次（dev → main）
#317：exerciser 进程外看门狗两处强化——心跳文件缺失不再静默放行（missing-since 追踪，超时照杀）+ teardown 阶段心跳标签（disposeApps 逐 app/cleanup/complete）。修复 2026-08-17 CI 挂起烧满 15 分钟而看门狗未开火的问题；下一个 teardown 挂起将 120s 内被终结并自报现场归因（#316 首个交付物）。
#318：Verdict Disposal Contract 注入持续核验至上线标准原则（双语关键提示词）——路由器判定三职责完整（replan/流程重组/新开 DAG），节点完成与构建绿均不构成闭环。
dev 验证
两 PR Typecheck 门禁均绿后合并；#317 本地双验证（干净 run 零误触发 exit 0；缺文件场景 3 秒开火）；#318 测试锚点 21/21 绿。
main 门禁
Typecheck + Unit Tests (linux) + E2E (linux/windows) 四项全绿后合并。
