-- **Outcome:** The background probes accessible frames, elects the visible HTML5 player without trusting child-frame claims, and routes injection, ordered commands, state, chat, audio and teardown to the selected document. Hidden equal candidates without visibility evidence are rejected. A tab-wide frame sentinel plus subframe-navigation events recover CSS visibility switches, document reloads, lazy video insertion and failed delivery. Google Drive and YummyAnime-style nested external players are covered by live topology inspection plus packed-Chromium E2E fixtures; live two-peer service runs remain tracked separately.

 Since v3.1.0 the content script walks **same-origin** frames, so a player wrapped in the site's own iframe is found and controlled without a site-specific workaround. This also covers `srcdoc` and `about:blank` frames, which inherit the parent origin.
 
 Since v3.1.2 the background can also inspect accessible **cross-origin** frames and inject KoalaSync into the exact frame/document containing the visible player. Frame election uses visibility and media signals so hidden preloads, trailers and ad players do not win accidentally. When browser site access for the external player origin is withheld, KoalaSync uses the existing website-access recovery flow instead of bypassing the browser permission.
+
+The currently verified cross-origin service topologies are:
+
+- **Google Drive:** `drive.google.com` top page → `youtube.googleapis.com/embed` player.
+- **YummyAnime:** `yummyanime.tv` top page → same-origin wrapper → `thealloha.club` player.
+
+These embedded origins are implementation details of the services and may change independently. If the browser withholds access to a newly used player origin, KoalaSync asks for that origin through its normal site-access flow.
