Do not leak username to untrusted modules

We must not leak the filesystem structure when the code is running inside a sandboxed environment. The Checker App files are usually in the user's home directory. The full path...

Add a built-in libp2p node allowing checkers to communicate with other nodes in a decentralised peer-to-peer fashion.

In our Cloudflare logs for api.filspark.com, I see two user agent values: - `zinniad/0.20.3 spark\main` - `zinniad/0.20.3 spark/main` Let's remove the `/main` portion from the user-agent string.

Network connection error freezes the runtime

Type-check Zinnia modules (checker subnet nodes)

1

We need to: - provide .d.ts typings describing Zinnia APIs - figure out how to tell typescript to load that d.ts file while type-checking checker subnet nodes, e.g. spark-checker. Tasks:...

Support WebRTC data channels
