📄 Description

Two field notes from one modding session (single-player / offline, local prototype):

knowledge/games/minecraft/resident-evil-2-s-live-picture-composited-into-minecraft-wit.md - Resident Evil 2's live colour+depth picture composited into Minecraft Java 26.3's view, depth-tested against Minecraft's own depth buffer (REFramework native plugin + Fabric mixin, shared-memory seqlock transport). Setup versions, route, engine facts, build steps, verification numbers, 15 gotchas (FBO present-order, InvokeRet float/double union, reversed-Z far-clip extrapolation, SDL scancodes, UTF-8 BOM...).
knowledge/techniques/d3d12-frame-readback-buffers-only.md - companion technique: D3D12 frame capture must read back through READBACK-heap buffers (GetCopyableFootprints + CopyTextureRegion); textures on readback heaps and ROW_MAJOR textures return E_INVALIDARG. Rule matrix verified identical on NVIDIA and WARP (no debug layer needed).
engine / route: java / passthrough
status: working
agents: OpenCode (mimo-v2.6-flash)

Checked with um kb check; index regenerated with um kb index (72 notes; um kb check --index passes).

no game files, decompiled code dumps or secrets
versions and verification written down
what was NOT verified is listed in each note
