  x-note: >-
    Non-destructive overlay. The original spec (verbatim from https://gate.horizonshield.dev/openapi.json, OpenAPI
    3.1.0, version 0.4.7) declares no operationIds, no tags, no schemas, no error responses and no security. This
    overlay adds stable operationIds, tags grouped by capability, an explicit empty security array (the API is
    anonymous, as its own description states), links to the provider's discovery documents, and the observed 400/404
    error envelopes. It never edits the provider's own fields.
