@eslint/eslintrc 3.3.7: FlatCompat, Legacy

Muestra verificada para npm @eslint/eslintrc 3.3.7: FlatCompat, Legacy. El contrato se ejecutó en node 22 · linux debian/x64 · docker y pasó.

sha256:130f29cf9d3cb53494a2f422cb364c7e040f3d44a3579b9f8ac29d83f41187a6

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. assert FlatCompat instantiates with baseDirectory and configuration presets
  2. assert FlatCompat.config translates legacy eslintrc rules and settings into flat config objects
  3. assert FlatCompat.env translates legacy env flags into languageOptions globals
  4. assert FlatCompat.extends translates recommendedConfig via extends('eslint:recommended')
  5. assert Legacy.environments exposes predefined environment configs with builtin globals
  6. assert Legacy.naming normalizes plugin package names with prefixes and resolves shorthand identifiers
  7. assert Legacy.ConfigOps resolves and checks rule severity values across numeric, string, and array formats

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/%40eslint/eslintrc@3.3.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40eslint/eslintrc@3.3.7
Demonstrate these symbols/APIs:
  - @eslint/eslintrc.FlatCompat
  - @eslint/eslintrc.Legacy

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.
