Reproduced against the live yummyanime.tv layout, which is:
top (no video)
├── visible same-origin wrapper 830x498 -> cross-origin player
├── hidden same-origin wrapper 0x0 -> cross-origin mirror
└── hidden cross-origin trailer 0x0
Three things kept that page from ever settling on a target.
Equally-ranked players were a hard failure. Several mirrors or dubs loaded at
once is an ordinary layout for these sites, and refusing to activate made them
unusable. The resolver now holds the top frame and waits for one of them to
start playing, which is the signal that breaks the tie.
Inconclusive probes moved the target. A page whose players are still loading
resolves differently from one call to the next, and every difference triggered
a full teardown and reinjection, so activation never finished — the popup sat
on "activating" with nothing in the log. A probe that finds no video now leaves
the target where it is.
The visibility handshake expired mid-probe. Its listener lived 1000ms while the
probe sequence is six separate executeScript round trips; on a heavy page it
was gone before the answer arrived, leaving every frame's visibility unknown —
the exact state that makes two players look equal. It now outlives the sequence.
A settled failure also no longer reports itself as "activating".
Covered by two fixtures built from the real page: one where the player exists
up front, and one where the host only creates it on play, asserting the target
is promoted into the deep cross-origin frame without touching the popup again.

The evidence for the frame-observation fixes was a reimplementation of the
logic measured in a browser console, not the shipped code. Two extension
specs now cover the observable behaviour end to end: a player frame that
swaps its document, and the same one level deeper.
The nested case fails against the pre-fix content.js and passes now. The
top-level case already passed before the fix, so that fix removed dead
observer registrations without changing what a user could see; recorded
here so the distinction is not lost.
Also adds bench-finder.mjs, which measures the extracted shipped finder
instead of a transcription of it.

The weighted score summed incomparable units, so size could outvote traits
that disqualify an element outright. Measured on a real page: a display:none
preload reports its full 1080p intrinsic size and scored 2073600, beating a
visible unmuted player at 509920.
Selection now compares an ordered list of signals, highest priority first:
has a source, is rendered, is not a silent background loop, rendered size
bucket, is playing, has controls, duration. Rendered size replaces intrinsic
resolution, and mute state is gone from the ranking entirely: it is a viewer
preference, not evidence about which element is the player.
It stays a ranking rather than a filter, so a page of only bad candidates
still yields one and findVideo never returns null where a video exists.
The new tests/e2e suite runs the shipped finder against real fixture pages
and drives the packed extension for injection, reinjection and remote
play/pause/seek into a first-party frame. All five scoring scenarios fail
against the previous implementation.
