+# LUT library (authoring)
+
+`index.json` is the agent-consumed catalog of color-grade looks. Each entry resolves
+on demand — no `.cube` bodies are committed to the repo.
+
+Each look has:
+
+- `id`, `description`, `tags`, `intensity` — matching + application metadata.
+- `url` (optional) — a hosted `.cube` downloaded, validated, and frozen at resolve
+  time, exactly like bgm/image assets.
+- `params` (optional) — a deterministic `buildCube` spec used offline (`--local-only`)
+  or as a fallback if the `url` download/validation fails.
+
+An entry needs at least one of `url` or `params`; prefer both (CDN url with a params
+fallback) so resolution is never blocked on the network.
+
+## Hosting a new look (operators)
+
+1. Generate the `.cube` (e.g. `resolve -t lut --params '{...}'` or a graded export).
+2. Upload it to the public CDN origin bucket:
+
+   ```
+   aws s3 cp <id>.cube s3://heygen-public/luts/<id>.cube
+   ```
+
+   It is then served at `https://static.heygen.ai/luts/<id>.cube` (CloudFront).
+
+3. Add an entry to `index.json` with that `url` (and ideally a `params` fallback).
