The settle-time decode was confirmed only against a SETTLED frame, which shows the end state is right and says nothing about whether the five flashes ever happen. This runs the oracle: a draw capture armed before the title exists, so the window contains the frames in which the screen is built. The flashes fire in a six-frame window and are absent from all 155 other sampled frames. `ptlogo_back2eff1` is drawn in exactly two frames at t = 54.0 against a decoded peak of t54-56; `ptlogo1` first appears at t = 42.2 against a decoded t42. Units-per-frame was taken from the GLOW's period alone, a different element, so the timings are not circular. The two holders are continuous from frame 134. The plate glow's quad carries a per-vertex colour whose alpha IS the element's fade alpha, so the ramp is read straight out of the guest: observed range 0..80 against a decoded peak of 80, exact and unfitted; period 51.158 presented frames over 20 cycle starts. Fitting the decoded ramp gives RMS 13.16 alpha levels against 38.18 for the same ramp REVERSED -- if the shape carried no information those would be equal, so the asymmetry is real and correctly directed. Further controls: symmetric triangle 15.73, flat 31.13. `ptlogo_back2eff3` was never drawn, and that is expected rather than a miss: a 2-unit flash peak is 0.85 of a presented frame, so catching one is a matter of phase. A port drawing all five every time shows more sweep than the console. METHOD.md gains the trap this cost: a 2D draw's identity is its vertex geometry, not its bound texture. These sprites sample shared pages, and matching texture dimensions produced a false negative (no flash is ever drawn) and a false positive (the intro movie's 640x360 YUV planes read as `ptbase2`) in the same pass. Also records the top-level restriction on the settle window, which the port raised and which is verified here: top-level [160,236] width 76, including the `ptloop` leaves [269,540] width 271 -- an instant past the end of every top-level element's timeline. Evidence committed as a derived per-frame series, not the 7 MB raw log.
