The avatar record carried as a Universal Manifest v0.4 document (Base, Tier 0, Signature Profile A): \"openspatials\": \"0.5\" beside \"manifestVersion\": \"0.4\"; one openspatials:Character facet (name, color, looks, ownership, requires) and one openspatials:Item facet per item, optional consents (the signing tool writes a show consent for the character and each item, purpose openspatials:game-crossing) and at most one openspatials:PlainCopy pointer. The character's fields follow the plain form's rules (character.schema.json). The signature is optional here: an unsigned record arrives unverified. Reason codes through x-openspatials-reason, as in character.schema.json: unknown-version > unsafe-file > too-large > invalid-file. Checked by code, not by this schema: the 64 KiB limit and duplicate JSON keys (on the bytes); exactly one character facet, whose @id, ref and entity @id equal subject; item facet @id equal to <subject>#item-<itemId> and no itemId twice; at most one plain copy pointer; the reading game's reads listing \"0.5\"; the signature, the key and freshness (src/ownership/index.js verifyAvatarRecord).",
