chat-rk1

Runbook for the mainline `rocket` NPU stack on RK1 nodes — the rockchip-rknn Talos extension + rocket DT overlay (baseline), the aarch64 runtime image + benchmark, and the Phase-B patched rocket.ko (600 MHz clock lever). Use when rebuilding the runtime image, (re)deploying the extension/overlay to a node, extending to another RK1, building the patched module, or when NPU inference breaks after an upgrade or power cycle.

Recover an RK1 node that boot-loops or dies mid-boot (e.g. after a bad DTB) using the BMC serial console, u-boot, and the TFTP rescue kit. Use when a Talos RK1 node won't come up after an upgrade or DTB change.
