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
- Ajv with removeAdditional true removes undeclared properties from validated objects only when additionalProperties false is explicitly specified in the schema, retaining undeclared properties when additionalProperties is omitted.
- Default Ajv without removeAdditional rejects input containing undeclared properties when additionalProperties is false.
- Ajv with removeAdditional 'all' strips undeclared properties even when additionalProperties false is omitted.
- Ajv with removeAdditional 'failing' strips only properties that fail the additionalProperties subschema while retaining valid extra properties.
