Thanks @Stefan Mihajlov for the tip. ` no app-hosting verification` doesn't see to exist anymore in 17.15 -- what tab completion gives is `no app-hosting signed-verification` which didn't change much. `show app-hosting infra` report then reported `IOX version: 2.12.0.3 [line-br] App signature verification: disabled`. Setting it from the web UI changed that setting: "Application Signature Validation is currently Disabled". Trying the below silently fails as before. (The web UI was more descriptive with an error message -- complaining "App signature validation is required")

End of the day, Cisco states this:
"Cisco does not provide any pre-packaged third party unsupported apps. Customers have to package it themselves. Certain third party vendors with whom Cisco has collaborated with can share a link specific to Cisco installation." https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9500-series-switches/222780-understand-app-hosting-on-catalyst-9000.html
It wasn't clear from their webpage, but the only "Cisco-signed" apps are (1) ThousandEyes and (2) Cisco DNA Spaces. Custom apps, and "open source" seems to require running from Cisco USB storage. https://developer.cisco.com/app-hosting/ciscosigned/
I was optimistic about a great solution utilizing powerful equipment we already owned to do some DNS resolving internally.
