이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

실행 증거

선언된 환경과 서명된 실행을 분리해 두었습니다. 이 샘플이 무엇을 어디서 실행했는지 그대로 볼 수 있습니다.

  1. atom.Body is a non-zero Atom representing the HTML body tag with string value "body"
  2. atom.Lookup with byte slice "body" returns atom.Body and lookup with uppercase "BODY" returns 0
  3. atom.String with byte slice "body" returns string "body"
  4. html.Parse resolves the <body> element node with DataAtom equal to atom.Body and Data equal to "body"
  5. html.Node constructed with DataAtom atom.Body renders as valid HTML body element
  6. atom.Body is distinct from other HTML tag atoms including atom.Head, atom.Html, and atom.Div

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 pkg:golang/golang.org/x/net@v0.59.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:golang/golang.org/x/net@v0.59.0

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.
