D3-TUI Agent Operating Contract

This repo is the canonical D3-TUI source of truth for FROM House Shachi work.

Authoritative current docs:

1. docs/REALIGNMENT_BRIEF.md
2. docs/D2_TITLE_MENU_TARGET.md
3. docs/ASSET_EXTRACTION_MAP.md
4. docs/BUILD_TARGET_POLICY.md
5. docs/AGENT_PROTOCOL.md

If any older doc, stage brief, or script conflicts with those files, the current docs above win.

Hard boundaries:

• Do not work on MIL-CD exploit booting.
• Do not make CDI the active target.
• Do not restore raw IP.BIN + binary concatenation.
• Do not assume physical Dreamcast hardware is required for this effort.
• Do not commit licensed D2 disc images, extracted D2 texture archives, or generated D2 pixel arrays.
• Do not delete archives, private assets, old containers, old images, or build evidence unless a human explicitly asks.

Target:

• RG40XXV/Knulli FlycastVL is the authoritative validation environment.
• The intended visual is the D2 Disc 1 title menu: snowy mountain background, snow flecks, translucent red D2 logo, menu stack, and WARP copyright.
• The previous W/A/R/P NLOGO.PVM plus 0GDTEX.PVR screen is decoder evidence only, not the final target.

When validation is blocked, keep working by reviewing code, tightening tests, improving docs, removing contradictions, filing issue notes, and making small traceable commits.
