src/upstream/client.ts is the only way this service talks to the Artcraft API. Middleware refuses, before anything leaves the Worker: routes not allowlisted for the client's `use` (tools = read, sign-in/out = auth), per-request baseUrl overrides to any other origin, and concrete URLs that do not match the allowlisted template (independent second check). The credential is attached last, so a rejected request never carries it. Read clients require a credential; auth clients may sign in without one. Tests (13): headers and URL of a good request, path substitution, array query params as repeated keys (what actix_web_lab parses), 401 passed through as a result not an exception, credential required for read, sign-in without and sign-out with a credential, and the gate firing — auth route from read client, read route from auth client, unlisted path, foreign baseUrl — each with fetch provably not called; path parameters are percent-encoded so they cannot escape their segment; the rejection message never contains the credential. CLAUDE.md layout updated for the upstream module and generated files. pnpm check: typecheck, eslint, prettier, 77 tests passing.

The IDE for artists.
ArtCraft
ArtCraft is the IDE for interactive AI image and video creation. We turn prompting into crafting, so your ideas become a form of tangible expression and computing. This is Adobe Photoshop for everyone, and we're giving away the source code!
Show, Don't Tell: Advanced Crafting Features
Text-to-image is great, but artists need control. It's important to know what your image will look like before you generate it, and it's vitally important to achieve consistency and repeatability.
Note: all of the above videos were generated for free with Grok Video; the cost to build this README was negligible.
Quick and Easy Prompting
We haven't abandoned text-to-asset generation for quick prototyping and ideation. We support every popular workflow in a first class fashion.
