Present as consumer Google Chrome, not Chrome for Testing. CfT's UA string already matches consumer Chrome, but its client-hints brands report only [Not/A)Brand, Chromium] while real Google Chrome includes a Google Chrome brand; Cloudflare and Akamai read that Sec-CH-UA brand list and wall the missing-Google-Chrome case (measured: DigiKey, Mouser, Arrow, SnapEDA, ComponentSearchEngine, Octopart all served Just a moment interstitials while manufacturer-direct TI, ST, ams loaded fine). Every tab now applies a UA override via CDP setUserAgentOverride that adds the Google Chrome brand to navigator.userAgentData and Sec-CH-UA, kept consistent with the UA header, with the major version read from the live browser so a CfT bump never drifts it. This is not device spoofing: it is the same Windows Chrome the user runs, correctly declaring itself as Google Chrome, which is the user's own machine surfing as a normal user.

Binds its local server to LOOPBACK (127.0.0.1) only, so no Windows Firewall 'allow Node through the firewall' prompt ever pops. Chrome for Testing is fetched only as a LAST RESORT if the machine has no Chromium browser at all. SPAWN-VERIFIED fallback: pup tries each detected browser (Chrome \u2192 Edge \u2192 CfT) and actually launches it, falling through to the next if one won't start (and handling browsers like Edge that relaunch onto another PID), so a corrupt/partial install never hard-fails an open. The browser that launches is cached as the default (persisted across restarts) so it isn't re-probed each time. On spawn the bridge SELF-WARMS: detects browsers + disk, and only if the box has no Chrome/Edge and no cached CfT does it background-fetch CfT so the first open is instant. pup_use pins a specific browser (chrome | edge | cft | auto); {browser:'chrome',install:true} downloads & installs REAL Google Chrome (user-scoped, no admin) on an Edge-only box. pup_readiness (READ-ONLY) reports which browser will be used + the full candidate list + the default + free disk. Every failure returns a specific errorCode + _hint (chrome_install_no_disk, chrome_download_network, chrome_install_permission, chrome_stable_not_detected, \u2026). Launches with FULL browser permissions by default for full debug (strictPermissions:true opts out). Headful automation: open/close windows+tabs, navigate, screenshot, eval JS, record. pup is a GENERIC, non-profile browser only \u2014 every session is a fresh isolated Chrome/Edge process, never the user's real signed-in browser; profile defaults to sessionId. To drive the user's REAL Chrome/Edge (their profile, cookies, SSO), use the Adom browser EXTENSION's nbrowser_* verbs \u2014 a separate bridge, not pup's job. macOS (v1.9.74+): full parity with mac-native mechanics \u2014 background-by-default is the app-level hide (windows stay drivable/screenshottable while hidden), raise/lower map to unhide+activate/hide, pup_alert_window posts a native toast whose click focuses the window, pup_use {browser:'chrome',install:true} installs Chrome from the official dmg, and taskbar identity/badging remains Windows-only.",   "homepage": "https://wiki.adom.inc/adom/adom-bridge",   "author": "Adom Inc.",
