Minecraft-TA rendering integration

Engineering record and source map for the 2026.09.13 stable project checkpoint: Minecraft 1.21.1 native DLAA, shaded foreground isolation, scRGB HDR, live output switching, modded UI composition and the accepted Full solar treatment.

The original combination was accepted in-game. Audited SR/Iris rebuilds passed offline and hidden GPU checks; they still need a short live acceptance pass. This is a project checkpoint on an upstream SR alpha, not a universal compatibility claim.

• Checkpoint, versions and remaining acceptance
• Architecture: what each repository owns
• Methodology and lessons
• History and findings
• Standards and specification audit
• Normal fixes separated for possible upstream PRs
• Exact artifact and source manifest
• Distribution boundaries
• Local recovery and cleanup

Published builds: SR and Iris. All four component forks have the coordinated ta-rendering-2026.09.13 source tag.

Source forks

Component	Source
Super Resolution	TA checkpoint branch
Iris	TA checkpoint branch
Sodium	Focused contribution branches
FramedBlocks	Optional material integration

HDR presentation and UI live in SR; adapted shader passes own HDR appearance. The Iris fork contains ordinary rendering fixes. Its PR branches exclude HDR, release branding and unrelated changes. No upstream PRs have been opened.

Shader packaging

This repository contains no generated shader pack, patch payload or derived GLSL. Complementary/Euphoria distribution conditions remain under review. We tested a version-locked patch locally: 119 file deltas reconstruct the accepted 681-file Full tree, matching the deterministic build byte-for-byte. Technical success is not permission to distribute the payload.

The generic utility and synthetic tests are included:

python tests/test_shader_patch.py
python tools/shader_patch.py create base.zip modified.zip patch.zip
python tools/shader_patch.py apply base.zip patch.zip output.zip

It rejects a mismatched base, corrupt output, unsafe paths and invalid copy ranges. It never deploys or downloads. tools/build_shader.py --source <local-shader-tree> can verify/package a locally available exact Full tree against the published file-hash manifest. That input tree is intentionally absent here.
