Phase 5 — Device node NOC

Layer: Native ↔ Headless JS ↔ cloud ↔ native

The Matter device generates a CSR during pairDevice; RainMaker cloud signs a node operational certificate; CHIP installs it on the device. This loop runs while ChipToolCommissioningActivity may still be showing pairing progress (same Headless JS design as any path that uses ChipClient + EspNOCChainIssuer).

Call chain​

Issue NOC failure​

ESPMatterModule.handleHeadlessTaskResult("ISSUE_NOC", { success: false }) (logged; commission may time out).

What could go wrong​

Cloud issueNodeNoC fails or Headless JS cannot authenticate → NOC never reaches ChipClient → CHIP commissioning times out. Network loss while the ChipTool activity is visible is common; Headless JS is intentional so cloud calls still run in a dedicated runtime.
