Power returns. The server starts by itself. 恢复供电，无需按键，T736 自行启动并恢复 NPU / MCP。

An operator physically removed and restored main power without touching the power button. The Mac independently observed TCP22 disappear and return, and the board reported a new boot. After boot dependencies completed, a fresh authenticated MCP Client executed pinned NPU and vendor Golden tests. 操作人确认主电源断开／恢复，且无人按电源键。新的启动周期中，网络、NPU 和 MCP 最终自行恢复，并由独立 Client 再次完成真实计算。这是一个有界的实测结果，不是长期可靠性认证。

What the first observer missed / 为什么最初显示 NOT_ACCEPTED： TCP22 became reachable before the LTE/PPP routing and vipcore startup units became active. The early test truthfully reported NOT_ACCEPTED_NEEDS_REVIEW; it is preserved unchanged. Independent readback on the same boot later showed those services ready, and a new official MCP client passed both fixed-model and Golden tests. 首次观察程序并非检测到自动开机失败，而是 SSH 恢复早于 LTE、USA2 与 NPU 服务就绪。原始失败回执完整保留，通过同一 boot 的后续服务回读与独立 NPU/MCP 调用形成增量接受证据。

Don't mistake transport for readiness SSH 可连接，不等于 Server 已经 Ready。

Five levels: R0 Auto Power → R1 Transport → R2 Network & NPU → R3 MCP Discovery → R4 Bounded Compute. Operational readiness requires R0–R3, and compute acceptance is a separate R4 check. 真正的 Readiness Gate 必须等待网络路由、NPU 驱动和独立 MCP 调用，不能只根据 SSH TCP22 可连就宣布就绪；计算 Golden 作为进一步的有界验收。

Latency not yet accepted / 尚未通过的计时： The same boot's SSH return was observed at 12:52:04.810 HKT while both NPU and USA2 systemd units entered active state at approximately 12:52:42 HKT, about 37 seconds later. The actual time power was restored was not instrumented; this is neither a cold-start-to-ready benchmark nor a guaranteed SLO. 系统服务约在 SSH 恢复后 37 秒才进入 active。目前不能把 13.831 秒的网络中断时间当作设备总恢复时间。

SCOPE AND CONTINUITY / 证据边界

What is—and is not—accepted经过验证，也明确尚未验证的范围

Accepted: one operator-attested no-button power restore; changed boot; delayed network and pinned NPU driver recovery; independent SSH-authenticated MCP 6/6; fixed NBG execution plus vendor custom_lut 256-byte Golden.

Not yet accepted: electrical instrumentation of total power loss, full cold-start-to-ready latency, many unexpected cycles, Mac-free second Host, general vision-model Golden accuracy, WD 4TB integrity, or a public MCP HTTP endpoint.

未重新接入 WD 4TB；没有增加公开 MCP 端口或通用工作执行授权。第二块 AIS T736 将作为独立节点重新识别，不继承 USA2 的已验收身份。
