Stream-verify the demo scenes: warp field + Klingon = DRAM-resident assets

Browse Source 
trek's live-written DMA stream contains ZERO non-standard SENDs (624 pairs, all
four standard payloads) -- the captured demo frames, like the bench, draw only
the SMPTE test card. The warp starfield and Klingon vessel geometry are the
demos' scene ASSETS resident in render memory (compiled coefficient blocks
never referenced by the captured frames' chains). §07 relabeled accordingly:
"Recovered assets -- the Star Trek material". Every image in the readout is now
attributed by stream evidence, not memory scanning.

<h2><span class="idx">07</span> The warp field — a Star Trek scene, recovered</h2>
<p class="sub">The archive's <span class="mono">trek</span> capture — unreleased Star Trek
material — <b>replays and draws</b> after the dual-instruction-mode fix. Walking the
per-region DMA chains in the bin pages enumerated <b>898 compiled payload programs</b> for
the frame: four are the standard end-of-frame pipeline (fog, texture, RGB — byte-identical
in every capture), and <b>~860 are the scene itself</b>, per-primitive coefficient blocks
with their geometry sitting in plain screen-space floats. Plotted below:
<b>433 star positions and 389 streaks</b>, radiating from a convergence point — the
<b>warp-speed starfield</b>, reconstructed from micro-code compiled by the board's own
firmware running on the emulated i860.</p>
<h2><span class="idx">07</span> Recovered assets — the Star Trek material</h2>
<p class="sub">The archive's <span class="mono">trek</span> and <span class="mono">klngvid</span>
captures — unreleased Star Trek material — replay after the dual-instruction-mode fix, and
their render memory holds <b>~860 compiled per-primitive payload blocks</b> beyond the
standard program. Stream-verification shows the captured frames themselves draw only the
test card (§06) — these blocks are the demos' <b>scene assets, resident in DRAM</b>:
compiled geometry awaiting draws that this recording never reached. Recovered below:
<b>433 star positions and 389 streaks</b> radiating from a convergence point — a
<b>warp-speed starfield</b> — and a vessel scene, both read from coefficient blocks compiled
by the board's own firmware on the emulated i860.</p>
