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
- Bun.password.verify throws an Error with code PASSWORD_UNSUPPORTED_ALGORITHM for arbitrary non-empty hash strings and PASSWORD_INVALID_ENCODING for malformed prefixes rather than returning false, while an empty string hash returns false.
- Bun.password.verify returns true for matching credentials and false for mismatched passwords when provided valid argon2id or bcrypt hashes.
- Bun.password.hash with an unsupported algorithm name throws a TypeError with code ERR_INVALID_ARG_TYPE listing supported algorithms.
- Bun.password.hash with out-of-range bcrypt cost rounds throws a TypeError with code ERR_INVALID_ARG_TYPE.
