Audit follow-up (2026-06-10), all validated before commit. #2 WebRTC — the shipped baseline now MATCHES the manually-validated config (behind a residential proxy: host=<uuid>.local, srflx=proxy egress, No-Leak, gathering completes, indistinguishable from vanilla Firefox on BrowserLeaks + CreepJS): - prefs baseline obfuscate_host_addresses False->True; add zoom.stealth.webrtc.disable_ipv6=True; drop the dead media.peerconnection.ice.disableIPv6 (no-op on FF150) - launcher auto-derives the proxy egress IP via _geo.prepare_session_geo (one round-trip shared with the timezone resolution) and feeds nICEr via STEALTHFOX_WEBRTC_PUBLIC_IP + STEALTHFOX_WEBRTC_DISABLE_IPV6 in _build_env (sync + async); an explicit caller env still wins. The C++ mechanisms were already in firefox-9 — this activates them, no rebuild. #1 drop orphan prefs zoom.stealth.timezone + zoom.stealth.seed (read by no C++; the live ones are juggler.timezone.override + zoom.stealth.fpp.hw_seed). #3 release title 'rev N' instead of 'rev firefox-N'. CI guards (unit, leak-safe — no real proxy/creds, the kind that would have caught this gap at zero cost): - shipped-baseline guard + no-orphan-prefs (test_webrtc_realness.py) - egress auto-derive in _build_env (test_launcher_helpers.py) - prepare_session_geo returns (tz, egress) (test_geo.py) CI keeps faking 'behind a proxy' with an in-process TCP-only SOCKS5 + RFC 5737 TEST-NET IPs; real-proxy residential realness stays a LOCAL manual gate. 449 unit pass.
