x-ownership
`x-ownership` appears in the info block. Its value is a string. Used by 3 providers across 10 OpenAPI documents. Observed values include `IoTConnect is Avnet's own IoT platform (docs.iotconnect.io is titled "Avnet /IOT`, `ezyVet is owned by IDEXX Laboratories, Inc. (acquired June 2021).`, `Published in the zincsearch/zincsearch GitHub repo; info.contact points`. Consistent with data & schema semantics — this is inferred from where the key appears and what it carries, not from any published definition.

Why this is not in OpenAPI
Extensions exist because a provider needed something the specification would not carry. Most of what they hold is not the API contract at all — it is operational metadata about the contract: documentation, lifecycle, policy, provenance, and now agents. That metadata is usually better placed alongside the contract, in an Overlay or an APIs.json index, than crammed inside it. See everything else doing the data & schema semantics job.
