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.

Contract

  1. archFromString maps valid architecture names to Arch enum values and throws for invalid architecture names
  2. toLinuxArchString formats architecture names according to package target type
  3. getArchSuffix returns empty string for default arch and hyphenated suffix for target arch
  4. getArtifactArchName maps architecture and target artifact extensions to distribution architecture names
  5. serializeToYaml serializes objects to YAML format string
  6. deepAssign performs deep property assignment and deduplicates merged arrays
  7. safeStringifyJson serializes objects to JSON while masking specified skipped keys
  8. isEmptyOrSpaces and isEnvTrue validate strings and evaluate boolean environment variable strings
  9. replaceDefault expands default placeholder with provided default list
  10. removePassword sanitizes password arguments in command strings with SHA-256 hashes
  11. InvalidConfigurationError constructs configuration error with message and error code

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:npm/builder-util@25.1.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/builder-util@25.1.7
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

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.
