Walking the bin-page DMA chains enumerated 898 SEND payload programs per frame: 4 = the standard end-of-frame pipeline; ~860 = the scene's per-primitive coefficient blocks at 0x815f000+, far beyond the old dump window. Their geometry sits in plain screen-space IEEE floats (+0x14/+0x18 and +0x24/+0x28): 433 star positions + 389 streaks radiating from a convergence point = the Star Trek warp-speed starfield, reconstructed from micro-code compiled by the original firmware on the emulated i860. Readout §06 now renders the warp field from the embedded position/segment data. Tools: dumpcontent.py (payload-region dump), content_frame.py (chain walk + payload parse + reconstruction).
