This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- simpleUpdateNotifier is an async function that checks for newer package versions from npm registry
- simpleUpdateNotifier opts out silently without network calls when stdout is not a TTY and alwaysRun is false
- simpleUpdateNotifier logs an update notification to stderr when a newer version is available and alwaysRun is true
- simpleUpdateNotifier persists lastUpdateCheck timestamp in XDG_CONFIG_HOME config directory
- simpleUpdateNotifier skips network check when last update check is within updateCheckInterval
- simpleUpdateNotifier does not log notification when latest registry version is equal to or older than current version
- simpleUpdateNotifier supports custom distTag parameter for targeting release tags like beta
- simpleUpdateNotifier catches network and parse errors gracefully without unhandled exceptions
