R12 复测 2 钉死：剩下的 226 只点名 /home/chv/workspace——工作区由 cloud-final 的 chv-sync boot 克隆出来，晚于 multi-user.target 约 9 秒，worker 的 5 次启动预算在工作区出现前耗尽（5 台 VM 2 台 failed，手工 reset-failed + start 后立即 active，二进制无辜）。 修法三选一，选 (a)——让服务根本不在工作区出现前启动： 新单元 chv-gitea-worker.path（PathExists=/home/chv/workspace， 工作区一出现即触发启动）+ 服务加 ConditionPathExists=/home/chv/workspace（开机那次启动在命名空间 搭建之前干净跳过，不 226、不耗重启预算）。两者缺一不可： Condition 本身绝不重试，没有 .path 它就是一次跳过、服务永远不 起；只有 .path 而无 Condition，开机那次启动仍会在命名空间搭建 时 226 撞上限速。WantedBy=multi-user.target 保留（is-enabled 仍 为 enabled），runcmd 只启动 .path 单元（cloud-final 时工作区尚 未 clone，直接 start 服务会 226）；.path 进 buildinfo contents 与两处 lockfile 登记，P6 预检由三件扩为四件。 不用 (b) 放宽 StartLimit：放宽只是把竞态窗口拉大，wake 时间在 负载下已翻倍（R12 复测 2），预算仍可能耗尽，仍是时序赌博。 不用 (c) 把工作区创建提前到 tmpfiles-setup 之前：/home/chv 本身 07:23:40 才出现（cloud-init 建 chv 用户），晚于 tmpfiles-setup （07:23:24）；硬约束：绝不盲目补 tmpfiles 行。ExecStartPre 也不 行——命名空间搭建在它之前，救不了 226。 测试：WorkerUnitBootRaceTest 新增 8 项——Condition 在位、 StartLimit 未放宽（修法语义钉）、.path 触发配对（PathExists + WantedBy、无 Unit= 覆盖）、服务 WantedBy 保留、build.sh 启用 .path + runcmd 只起 .path、绝无工作区 tmpfiles 行、buildinfo 与 lockfile 登记；BuildInfoContentsTest 的 P6 件加 .path；P2/P4 干 跑夹具一并拷入 .path。P6/P2/P4 三模块 174 项全过。
