Reverse-engineered the migrated 4k69 player: jwplayer now serves OK.ru CDN (okcdn.ru)
mp4s. The static page (SSR behind Cloudflare, fetched via proxy) carries "file"+"label"
pairs for every quality. okcdn's srcIp param is NOT enforced (cross-IP test 2026-06-14:
206 video/mp4 from a residential IP != srcIp), so the URL plays from any IP. Parse the
okcdn sources server-side and return them mobile_direct_ok — the phone plays the direct
video, no WebView, no VAST preroll, no age-gate, zero VPS proxy. Skips 4K/2K. Reverts
the brief _vps_blocked_fallback routing (WebView grabbed the preroll ad, not content).
Verified on emulator: native player streams the actual scene (report 5de3fbc5).
