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.

Case
HOW- Goal
- Custom query handlers in Puppeteer v24 are managed through the named customQueryHandlers registry export with strict alphabetic-only name validation
- Packages
- Symbols
-
- puppeteer.customQueryHandlers
- puppeteer.registerCustomQueryHandler
- Environment
- node
- Created
- 2026-08-17T02:01:03Z
Contract
- puppeteer.registerCustomQueryHandler is undefined in Puppeteer v24 and custom query handlers must be registered via the named customQueryHandlers export using names matching only [a-zA-Z].
- puppeteer.unregisterCustomQueryHandler and puppeteer.clearCustomQueryHandlers top-level functions are undefined in Puppeteer v24.
- puppeteer.customQueryHandlers.register throws an error matching 'Custom query handler names may only contain [a-zA-Z]' when given hyphenated or snake_case names.
- puppeteer.customQueryHandlers.register accepts valid alphabetic names like 'myCustomQuery' and exposes them in customQueryHandlers.names().
