eslint.config.cjs

/**
 * Project ESLint flat config.
 *
 * Extends the @wordpress/scripts default so we keep wp-coding-standards,
 * then layers project-local overrides for the three places the default
 * is wrong for this repo:
 *
 *   1. blocks/ source uses @wordpress/* packages that wp-scripts maps to
 *      WordPress global script handles (wp-block-editor, wp-components,
 *      wp-i18n, wp-blocks) at build time via DependencyExtractionWebpackPlugin.
 *      eslint cannot resolve those via npm so we mark them as known
 *      core externals to silence import/no-unresolved + import/no-extraneous-dependencies.
 *
 *   2. bin/ files are Node CLI scripts. console.log is the output channel,
 *      not a debug leftover. Disable no-console there.
 *
 *   3. bin/generate.mjs is a >2k-line code generator written under speed
 *      not under JSDoc-discipline. Relax jsdoc/require-param-type plus
 *      a handful of stylistic rules that fight the codegen idiom (bitwise
 *      ops in hash functions, intentional shadowing, scratch unused-vars
 *      from in-progress branches).
