Two results, one of which corrects me. 1. The R1-re-opened 'declared keyframe timeline reproduces the captured splash' resolves in FAVOUR of the declared timeline. Instrument is a disc keyframe table against the guest's vertex stream -- no renderer in the chain, which is what the 'our-reader' tag demanded. Calibration-free test: is each captured alpha an exact member of the declared piecewise-linear value set at integer t? 39/50 exact under truncation, 30/50 under rounding, and the worst error under either rule is ONE alpha level in 255. All 11 non-exact samples are low by exactly 1 and all are on falling segments. The old refutation rested on 'still at a=255 nine frames after its declared a=32' -- under the fixed layout a=32 is at t=206, four units from the end of a 210-unit timeline. That was the off-by-one association. 2. The unit->seconds rate is PER-GAMEPART, which corrects what I told the port an hour ago. Title ~57 units/guest-second; splash ~35-40. The splash figure is confirmed two ways that share no algebra: a 15-unit ramp (T read off the disc, not borrowed) and a 160-unit HOLD, which is a declared duration with no T, no alpha slope and no interpolation in it. And my 'the borrowed T=15 does not apply' was wrong in the other direction: the disc says T=15 plainly. What failed was the premise of a single global rate, not the T. Noted at the foot of that page rather than by editing it. The trap worth recording: all four elements give 650-679 alpha/s, agreeing to 2%, which reads exactly like one clock. It is a coincidence -- T differs 22 vs 15 and the rates differ 57 vs 37, and the ratios nearly cancel. A quantity that looks constant across screens is not evidence of one clock when the thing that would vary is inside it. The hold breaks the tie. For the port: a single keyframe_units_per_second cannot be right, and a splash played at 60 runs 1.5-1.7x too fast -- shorter, sharper fades than the game's, which is the direction the play-test reported.
