Canonical build path:

make clean
make d2-assets
make flycast-image

Key changed or added files:

Makefile
README.md
docs/FLYCAST_PIPELINE.md
docs/STAGE3_INDEX/T5.md
scripts/build-dreamcast.sh
src/d3tui_main.c
src/d3tui_kos_stubs.c
src/d3tui/assets/d2_menu_assets.c
src/d3tui/assets/d2_menu_assets.h
tools/extract_d2_menu_assets.py
asset-staging/d2/0GDTEX.PVR
asset-staging/d2/NLOGO.PVM
asset-staging/d2/README.md

Pipeline behavior now:

• make flycast-image is the canonical accepted artifact path.
• make d2-assets regenerates RGB565 C assets from private extracted D2 PVR/PVM sources.
• Legacy cdi/iso targets route to the canonical Flycast ELF path instead of raw image creation.
• docs/FLYCAST_PIPELINE.md now requires screenshot proof showing D2 visual assets.
• Broken generated images were quarantined under artifact-quarantine/20260510T171805Z.

Environment correction:

from-agent-minimax-01      stopped
from-agent-minimax-02      stopped
from-agent-minimax-03      stopped
from-agent-mistral-01      stopped
from-opencode-deep-index   stopped
from-opencode-synthesis    stopped

These containers had restart policy unless-stopped, so docker stop keeps them stopped until explicitly restarted. Forgejo, FROM Forgejo, Shachi HQ, and Jellyfin were left running.
