YAML file (autotel.yaml or AUTOTEL_CONFIG_FILE)\n * 2. Environment variables (OTEL_*, AUTOTEL_*)\n * 3. Built-in defaults\n *\n * Environment Variables:\n * - OTEL_SERVICE_NAME: Service name (required for meaningful traces)\n * - OTEL_EXPORTER_OTLP_ENDPOINT: OTLP collector endpoint (e.g., http://localhost:4318)\n * - OTEL_EXPORTER_OTLP_HEADERS: Auth headers (e.g., x-honeycomb-team=YOUR_KEY)\n * - AUTOTEL_INTEGRATIONS: Comma-separated list or 'true' for all (default: http,express)\n * - AUTOTEL_DEBUG: Set to 'true' to enable console span output\n * - AUTOTEL_CONFIG_FILE: Path to YAML config file (overrides autotel.yaml discovery)\n *\n * @requires Node.js 20.6.0 or later\n */\n\n// namespace import for browser-bundler compat — see node-require.ts\nimport * as nodeModule from 'node:module';\nimport { createAddHookMessageChannel } from 'import-in-the-middle';\nimport { init } from './init';\nimport { loadYamlConfig } from './yaml-config';\n\n// Register ESM hooks first (must happen before any instrumented modules load)\nconst { registerOptions } = createAddHookMessageChannel();\nnodeModule.register(\n  'import-in-the-middle/hook.mjs',\n  import.meta.url,\n  registerOptions,\n);\n\n// Load YAML config if present (init.ts will also load it, but we need values here)\nconst yamlConfig = loadYamlConfig();\n\n// Parse auto-instrumentations from environment variable (fallback if not in YAML)\nconst autoInstrumentationsEnv = process.env.AUTOTEL_INTEGRATIONS;\nconst autoInstrumentations:\n  | string[]\n  | boolean\n  | Record<string, { enabled?: boolean }> =\n  autoInstrumentationsEnv === 'true'\n    ? true // Enable all auto-instrumentations\n    : autoInstrumentationsEnv\n      ? autoInstrumentationsEnv.split(',').map((s) => s.trim())\n      : (yamlConfig?.autoInstrumentations ??
