Worker preflight + watch

lightnode-sdk

workerWatch streams state-change events (registered, went-stale, jobs-completed) for any worker, no key required.

Preflight runs against the live network with YOUR private key, so it can't fire from the browser. Sample output:

{
  "verdict": "ok",
  "elapsedSec": 9.4,
  "worker": "0xabc...",
  "summary": "OK in 9.4s. Worker 0xabc... replied with 14 chars.",
  "txs": {
    "createSession": "0x...",
    "submitJob":     "0x...",
    "jobCompleted":  "0x..."
  }
}

Run it locally: PRIVATE_KEY=0x... npx lightnode worker preflight --net testnet

Models on-chain (AIConfig)

On LightChain mainnet the official model registry is AIConfig - whitelisted models, fees, and output limits. ln.getModels() / ln.estimateFee() read it directly. The custom lcai_listSupportedModels RPC method returns the live whitelist.
