    note: Splunk's own OpenAPI objects, extracted from the React Server Component payload embedded in each of the 48 API reference pages at dev.splunk.com. The operations and schemas are Splunk's; the assembly into standalone documents is API Evangelist's. Splunk serves no fetchable spec file — dev.splunk.com answers 200 with an identical 6,638-byte shell for every asset path, including invented control paths — so this is NOT first-party publication and is not graded as such.
