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
- Struct.update populates scalar, boolean, null, nested dict, and list fields with automatic Value and ListValue wrapping, while assigning unsupported types raises ValueError.
- Struct helper methods get_or_create_struct and get_or_create_list instantiate child containers in-place and support append, extend, and index mutation.
- Any.Pack serializes arbitrary protobuf messages including Struct with default type.googleapis.com URL prefix or explicit custom prefix, and TypeName extracts the clean message name.
- Any.Is verifies descriptor matching, while Any.Unpack deserializes the payload into matching message instances and safely returns False without modifying destination on type mismatch.
- MessageToDict and ParseDict round-trip Struct directly as native dictionaries and Any containers with @type discriminator metadata.
