cleanup releases it. The static preparation before `0x21c` is not a movie teardown boundary.
**Manual-test correction (2026-07-11):** the initial port incorrectly treated those pre-yield static loads
as surface replacement, producing start/first-frame/stop all in render frame 0. The bounded host now keeps
the movie as an independently updating retained layer, parks `0x21c` until the DirectShow completion event,
then permits cleanup. A real-render lifecycle run records first frame 98 and stop frame 181. The screenshot
sequence's known stale-CG/transition behavior can obscure this layer, so screenshot appearance is not used
as the visual oracle. **Manual recheck remains unresolved:** normal interactive SC0000 logs start, changing
frame delivery, EOF, and delayed stop, but the movie is not visibly presented in the application. The next
slice must diagnose compositor/layer publication rather than reopening decode or VM-lifecycle timing.
**Manual-test corrections (2026-07-11):** the initial port incorrectly treated pre-yield static loads as

the movie through `0x21c` until DirectShow completion. A follow-up compositor trace proved the movie object
was present at the correct z-position, but the static AGF cache reused the first decoded sample forever
because every sample has the same `(assetId,colorKey)`. An unconditional current-sample backbuffer copy did
not help because normal retained composition immediately covered it with that cached first sample. Movie
surfaces now bypass the static cache and publish only through the retained object. A windowed run records
first frame 101 and stop frame 190; the user manually confirmed visible playback. The separate lower white
textbox-area object remains outside this finding, as does the deliberately unrendered movie audio stream.
