• free_webmail_developer store Developer email poyrazolcay62@gmail.com; no verified publisher; no business website confirmed.
• js_external_hosts_broad crx 8 external JS hosts including Netflix, Instagram, YouTube, X, OpenAI — anomalous for a wallpaper/newtab.
• game_portal_shell_pattern store yowgames.com in both install/uninstall URLs matches game-portal monetization shell fingerprint.
• no_csp manifest content_security_policy is null; MV3 provides some default protections but no explicit CSP declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Electric Guitar Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.47 -> 7.97 (+2.5 cap 2.5).
