thread-manifest — the World Manifest format of the Thread

The World Manifest is the "HTML" of the Thread: an open, renderer-agnostic JSON description of a place that any browser can resolve and render. This crate is the reference implementation of the format — parse, validate, and address worlds — depending only on serde and thread-id, so anyone building for the Thread can use or reimplement it with no engine baggage.

In this repository the crate is named infinite-manifest for historical reasons; it is published to crates.io as thread-manifest. See docs/thread/publish-thread-crates.md.

What it gives you

• WorldManifest — the document: world metadata, environment (sky, time), spawns, prefabs (built-in or glTF meshes + a standard PBR material), instanced placements, portals (the hyperlinks — veils to other worlds), sandboxed WASM behaviors, and optional presence.
• WorldManifest::from_json / validate — parse + check conformance: the version tag is recognized, every reference resolves, and portals address the Thread. The same check the conformance suite runs.
• Locator — the address of a place: thread://host/world@when#place, with well_known_url() for decentralized .well-known hosting.

use infinite_manifest::{WorldManifest, Locator};

let world = WorldManifest::from_json(json_text)?;
println!("{} — {} veils", world.world.title, world.portals.len());

let loc = Locator::parse("thread://studio.example.com/gallery#entry").unwrap();
assert_eq!(loc.host, "studio.example.com");
