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.

HOW- Goal
- delegate file system operations and log method calls using Hfs from @humanfs/core
- Packages
- Symbols
-
- Hfs
- Hfs.prototype.logEnd
- Hfs.prototype.logStart
- Hfs.prototype.resetImpl
- Hfs.prototype.setImpl
- Hfs.prototype.text
- Hfs.prototype.walk
- Hfs.prototype.write

Contract
- Hfs creates an instance with a custom base implementation and confirms isBaseImpl
- Hfs write encodes string data and text decodes underlying bytes via the implementation
- Hfs logStart records method calls with arguments and logEnd retrieves the logged entries
- Hfs setImpl replaces active implementation and resetImpl restores the base implementation
- Hfs walk traverses directory structures depth-first and applies entry and directory filters
- Hfs rejects invalid path arguments and empty log names with TypeError
