  "description": "Spec: src/spec/core/OWNERSHIP-AND-UM.md. The character file's ownership link points to a signed Universal Manifest v0.4 manifest (Signature Profile A). A manifest grants rights only when signature.keyRef names the game that issued it, as <address of its openspatials-world.json>#<key id>, and that game lists the key in signingKeys in its profile. src/ownership/index.js checks this, not this schema. This schema is the copied Universal Manifest v0.4 schema plus our conventions: Ed25519 only; no code-like fields; a character facet's @id and ref are the character file's absolute URL; an item facet's @id is <character URL>#item-<id>; entity @type includes openspatials:Character or openspatials:Item. Consent purpose openspatials:game-crossing and scope words show, use and copy are checked by src/ownership/index.js, not here, because a manifest may carry consents for other purposes. Limit 64 KiB and no duplicate JSON keys, checked on the bytes. Every failure here maps to ownership-unreadable.",
