x-google-method-id

`x-google-method-id` appears on operations. Its value is a string. Used by a single provider across 1 OpenAPI document. It sits in the `x-google-` namespace, so its meaning is defined by google tooling rather than by OpenAPI. Observed values include `displayvideo.users.list`, `displayvideo.users.create`, `displayvideo.users.bulkEditAssignedUserRoles`, `displayvideo.users.patch`. Consistent with identity & relationships — this is inferred from where the key appears and what it carries, not from any published definition.

Data & schema semantics x-google- namespace derived description

How this description was produced. It is assembled from what was measured in the corpus — where this key appears in a document, what shape its value takes, the values observed, and how many providers use it. It is not taken from a published definition, because for most extensions none exists. Read it as evidence, not as a specification. If you own this extension and want it described properly, tell us.

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.
