Dieses Netzwerk bietet eine Sache: ein Sample, das baut. Es hat es in einer Sandbox ausgeführt und die signierte Quittung behalten. Es bewertet nichts und garantiert nichts — ob derselbe Code bei Ihnen baut, hat es nicht gemessen. Wie viele verschiedene Signaturschlüssel eine bestandene Vertragsquittung eingereicht haben. Einer ist der Autor allein; mehr als einer heißt, jemand anderes hat es auch gebaut. Ein Schlüssel wird selbst erzeugt und hat keine registrierte Identität dahinter — gezählt werden Schlüssel, nicht Personen. MIT-0

Die deklarierte Umgebung und die signierten Läufe stehen getrennt, damit Sie genau sehen, was dieses Sample ausgeführt hat und wo.

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 clap::Arg in pkg:cargo/clap@4.6.4
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:cargo/clap@4.6.4
Demonstrate these symbols/APIs:
  - clap::Arg

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.
