Low-Context Execution Packet

Use branch stage/d3-06-native-title-scene.

Create or reuse a frontend tree with a boring layout:

frontend/kos/
  Makefile
  src/main.c
  src/render_scene.c
  src/render_scene.h
  src/input.c
  src/input.h
  romdisk/
  assets/

Implementation order:

1. compile a blank KOS loop from D3-04
2. query Shachi atoms for the render/input/texture surfaces being touched
3. load placeholder or extracted preview assets
4. render background/snow layers
5. render logo or logo proxy
6. apply D2_PHYSICS_MANIFEST.md constants
7. package ELF and CDI if feasible
8. capture emulator proof

Dreamcast/KOS constraints:

• fixed-size buffers only
• no blocking file/network calls in the render loop
• 60 FPS target if emulator path can measure it
• all proprietary asset use must reference D3-05 provenance

Minimum verification:

make -C frontend/kos clean all
file frontend/kos/*.elf

docs/NATIVE_SCENE_REBUILD_REPORT.md must include:

• build host and command
• artifact path
• renderer modules changed
• screenshot/video path
• known visual deviations from D2
• Shachi atom IDs cited for PVR/rendering decisions
• next prompt for D3-07
