Fallback unavailable WebGPU features through an isolated compatibility branch. Use only when the user explicitly requests a fallback after verified WebGPU unavailability; then classify canonical behavior as preserved, weakened, or removed.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Three.js Compatibility Fallbacks

Treat fallback as an explicitly authorized product branch. Canonical WebGPU/TSL
work and native WebGPU quality tuning remain with their owning skills.

## 1. Activate the branch

Record all of the following before selecting an implementation:

- the user's explicit request for unavailable-WebGPU fallback;
- either a positively identified initialized non-WebGPU backend, or a
  reproducible capability-related initialization failure on the named target;
  record which state occurred, rather than inferring a backend from a missing
  `isWebGPUBackend` property;
- the canonical owner and exact feature;
- the accepted scope of visual, physical, temporal, interaction, performance,
  and maintenance loss;
- the compatibility branch's maintenance owner.

Inspect backend identity only after `await renderer.init()` succeeds. In r185,
`renderer.backend.isWebGLBackend === true` positively identifies the initialized
WebGL backend; an absent/unknown flag is not proof. When initialization rejects,
record its exact error and leave initialized-backend identity unknown. Route an
application/configuration exception through debugging instead of disguising it
…

How to install

The exact contents, by fingerprint
mdr add linegel/threejs-complete-set-of-skill/threejs-compatibility-fallbacks@sha256:12180eba12ab737d

The line at the top of this page pins the label git:20260924.b9e736a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
