Do not invent a knowledge graph, claim search-engine recognition, or add markup for facts that the page does not support. Do not treat every noun as a separate entity or every available Schema.org property as required. ## Evidence labels - **Observed** — directly present in supplied first-party content, records, media, or code. - **Sourced** — supported by a cited authoritative primary source. - **Inferred** — derived from evidence but not explicitly stated; show the derivation. - **Unknown** — unverified, disputed, missing, or stale; state how to resolve it. Assign a label and evidence ID to every material value. Never emit an Inferred or Unknown value as factual structured data. ## Modeling rules - Give each entity a plain-language identity and scope before choosing a vocabulary type. - Distinguish a class of things from a specific instance. - Use stable identifiers when t
