  version: 1.0.0
  description: >-
    Non-destructive enhancements to the provider's OpenAPI 3.1 (openapi/ingest0r-com-openapi.yml, verbatim copy in
    openapi/_original/ingest0r-com-openapi.json). Adds tags the spec lacks, links the provider's own discovery
    documents, and records the live-observed free-tier and rate-limit headers. Generated 2026-09-19; the original is
    never mutated.
