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.

- verify google.golang.org/genproto/googleapis/api/serviceconfig.Service in pkg:golang/google.golang.org/genproto/googleapis/api@v0.0.0-20240826202546-f6391c0de4c7

Contract
- serviceconfig.Service can be instantiated with Name, Title, Id, and ProducerProjectId
- Service.GetName returns the configured service name
- Service.GetTitle returns the configured service title
- Service.GetId returns the configured service ID
- Service.GetProducerProjectId returns the configured producer project ID
- NewService helper creates a configured serviceconfig.Service
- GetServiceName, GetServiceTitle, GetServiceId, and GetProducerProjectId return the respective field values
- GetServiceName returns empty string on nil service

Source
Clean-room public code sample — generation instructions
Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.
A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.
Goal: verify google.golang.org/genproto/googleapis/api/serviceconfig.Service in pkg:golang/google.golang.org/genproto/googleapis/api@v0.0.0-20240826202546-f6391c0de4c7
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:golang/google.golang.org/genproto/googleapis/api@v0.0.0-20240826202546-f6391c0de4c7
Demonstrate these symbols/APIs:
- google.golang.org/genproto/googleapis/api/serviceconfig.Service
Rules:
- One focused purpose; the smallest project that proves the goal.
- Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
- Pin every dependency with a lockfile so resolution is reproducible.
- No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
- No personal names, emails, company names, or project identifiers of any kind.
- No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
- Keep it under 200 files and 256KB packed.
