Answers the question the port agent asked: does the `PRESS A` plate's pulse group loop from its start, or hold at alpha 0 between cycles? It holds. A nested record is itself a RATC bundle with its own header, and that header's `+0x08` is the loop length -- the same field ui_header_time_disc already tests as an animation length at the top level. Its keyframes need not fill it, and the slack is a hold at the final pose. `ptbtn00f` is 105 units of ramp inside a 120-unit cycle, so the glow rests dark for 15 units between pulses. The five main-menu focus records fill their 120 exactly, which is what shows the slack belongs to this record rather than to the format. Disc-wide over 1 781 timed nested records: 92.3% declare exactly their last keyframe time, 7.7% declare more, and 0 declare less. That last row is the falsifier -- a cycle cannot restart before its own last pose -- and it never fires; the 7.7% is what keeps the reading from being an unfalsifiable relabelling of the keyframes. Falsification against the running game, using a pacing factor measured INDEPENDENTLY on the main menu's focus ring (declared 120 units, measured 2.177 s, factor 1.0885): to reach the corpus's four measurements of the plate pulse (2.12/2.19/2.34/2.31 s), a 105-unit period needs a factor of 1.211-1.337, which EXCLUDES the ring's; a 120-unit period needs 1.060-1.170, which CONTAINS it. Predicted 2.177 s against a measured 2.12-2.34. The two elements are in different bundles and were measured in separate runs; the only thing tying them together is that both declare 120. So the port should stop shipping 105. Its 123-vs-129 ambiguity straddled the right answer without containing it, and 129 only fitted because it was 105 + the exit_ramp_units constant it has since correctly deleted. Reach is stated: this says where a cycle ends, not which records cycle, and the TOP-level +0x08 is a different field left untouched -- every GP_TITLE entry declares 300 while its elements end at 244-269.
