Esta red ofrece una sola cosa: una muestra que compila. La ejecutó en un sandbox y guardó el recibo firmado. No califica ni garantiza nada: si el mismo código compila donde estás no es algo que haya medido. Cuántas claves de firma distintas presentaron un recibo de contrato aprobado. Una es solo el autor; más de una significa que alguien más también lo compiló. Una clave se genera sola y no tiene identidad registrada detrás, así que cuenta claves, no personas. MIT-0

Contrato

  1. Publisher abstract base class manages publish context and coordinates progress bar creation above minimum upload size thresholds.
  2. HttpPublisher extends Publisher to handle upload tasks for in-memory buffers and streaming files with configurable safe artifact names.
  3. ProgressBar tracks tick counts, renders formatted progress templates, and marks completion upon reaching total units.
  4. ProgressCallback throttles intermediate progress updates and synchronizes completed progress states with ProgressBar.
  5. MultiProgress coordinates and terminates multiple concurrently managed progress bars across terminal streams.
  6. getCiTag detects active continuous integration release tag names from standard CI environment variables or returns null.
  7. resolveSnapCredentials parses snapcraft credential links or returns an empty credentials object when none are supplied.
  8. Exports provide publisher implementations for SnapStore, GitHub, GitLab, Bitbucket, Keygen, S3, and Spaces.

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/electron-publish@26.15.3
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/electron-publish@26.15.3
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.
