CydandClaude Opus 4.8 90fd3497d1 Readout §02: real decoded DMA list + embedded-float payload finding
§02 now shows the actual per-region DMA command list captured from the emulator
(region 0x0801fa40: SEND/SENDE/TXDN/TILE/GOTO) and the real SENDE payload with
its embedded float coefficients (bit-serial MEMpluseqMEM sweep). §05 + the
last-mile list updated: the micro-code is partly decoded (lists clean, payloads
carry recoverable floats), remaining work is the control-word field split.

CydandClaude Opus 4.8 7bd6af8c20 Readout: add the Tier-1 Pixel-Planes array section (§05)
Signal-chain Pixel-Planes stage flips to "simulated"; new section shows the
64x128 tile footprint the array lit for the object (18/50), the 26-byte
pixel-memory bit layout (Z24 + RGB), and states the validation + the honest
remaining gap (the compiled micro-code binary, still undecoded, that carries
the ground/sky).

CydandClaude Opus 4.8 e43cf24993 Decode the captured object: it's a complete 9x5 height-field surface
The 45 VSTRIP vertices captured off the i860 sort back into an exact 9x5
model-space grid (x,z in even 2-unit steps, y = height at every node; all
45 cells filled). cap7's death-camera views it nearly edge-on, which is why
the raw screen projection looks like a folded sliver. gridsurf.py rebuilds
the true grid connectivity (2 tris/quad) and shades it from the firmware's
own per-vertex normals -> a clean solid surface. render-readout.html now
leads with that true-3D reconstruction and shows the grazing projection +
wireframe as "how the death-camera saw it".

Also resolved a long-standing red herring: the (1,1,10,10) extent bounds
that earlier sessions chased as the "empty-bins bug" appear identically in
the working frame -- they're the per-frame marker rect, not the geometry.

CydandClaude Opus 4.8 32ac5ca9b8 Shaded frame: Gouraud raster of the i860's projected geometry
Captures the object cap7's death-camera view draws (4 VSTRIP strips, 45
verts) with its per-vertex normals straight off the emulated i860, and
shades it in software with a barycentric z-buffered fill (shade_render.py).
This is our rasteriser showing the firmware's geometry lit by the firmware's
own normals -- not the board's bit-serial Pixel-Planes array (that stays the
Tier-1 build). cap7-geometry.json is the portable capture; render-readout.html
is the published readout with the shaded frame as its hero.
